详细IDEA整合Maven+SSM框架附带源码

网上很多整合SSM博客文章并不能让初探ssm的同学思路完全的清晰，可以试着关掉整合教程，摇两下头骨，哈一大口气，就在万事具备的时候，开整，这个时候你可能思路全无 _中招了咩 ，还有一些同学依旧在使用eclipse或者Myeclipse开发，我想对这些朋友说IDEA 的编译速度很快，人生苦短，来不及解释了，直接上手idea吧。这篇文章每一步搭建过程都测试过了，应该不会有什么差错。本文章还有个比较优秀的特点，就是idea的使用，基本上关于idea的操作都算是比较详细的，所以不用太担心不会撸idea！最后，本文章旨在清晰地整合各个框架之间的流程与思路。

相信有很多小伙伴都是学了SSM框架，而且学的时候应该是用eclipse或者Myeclipse开发的，随着idea崛起，实力碾压eclipse，IDEA 的编译速度很快，通常比ec快2倍！外加丧心病狂的代码提示引起程序员的尖叫！当然，我不是说eclipse不好，只是idea更加便捷，更加便于开发，这是事实。我相信很多小伙伴都是从eclipse转向idea（包括我，普遍一开始上手不习惯idea，时刻保持一颗畏惧敬畏的心，生怕敲不出一行靓丽的Hello Word（你们都是大神，记得当时的我一直syso，敲不出一行输出语句QAQ），作为过来人，我告诉大家，这些都是没必要的担心，你只要记住，具（工具idea）在我手中，码（代码）就在我手中，管他三七四十九呢，拿起idea就是一顿撸码，我就是酱紫的，所以呢才有了这篇idea版的SSM框架整合，不然你以为怎么来的？

1. 搭建整合环境

1. 整合说明

整合说明：SSM整合可以使用多种方式，咱们选择XML + 注解的方式，不要觉得不妥，这样其实最便捷-

2. 整合的思路：

1、先搭建整合的环境

2、先把Spring的配置搭建完成 3、再使用Spring整合SpringMVC框架 4、之后使用Spring整合MyBatis框架 5、最后spring整合mybatis框架配置事务（Spring的声明式事务管理）

3. 创建数据库和表结构语句：

复制在MySQL中运行即可：

create database ssm;
use ssm;
create table account (
id int primary key auto_increment,
name varchar(50),
money double
);

4. 创建maven的工程

具体的使用idea创建maven，请看这篇使用IntelliJ IDEA创建第一个Mawen项目

1. 创建Twossm_parent父工程（打包方式选择pom，必须的）
2. 创建Twossm_web子模块（打包方式是war包）
3. 创建Twossm_service子模块（打包方式是jar包）
4. 创建Twossm_dao子模块（打包方式是jar包）
5. 创建Twossm_domain子模块（打包方式是jar包）
6. web依赖于service，service依赖于dao，dao依赖于domain
7. 在Twossm_parent的pom.xml文件中引入坐标依赖
   找到对应的< properties >标签，以及< dependencies >标签，复制粘贴即可
   版本控制是在< properties >标签中控制，从坐标依赖中可以看出版本号：spring5X、MySQL3.1.6、mybatis3.4.5

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <maven.compiler.source>1.7</maven.compiler.source>
    <maven.compiler.target>1.7</maven.compiler.target>
    <spring.version>5.0.2.RELEASE</spring.version>
    <slf4j.version>1.6.6</slf4j.version>
    <log4j.version>1.2.12</log4j.version>
    <mysql.version>5.1.6</mysql.version>
    <mybatis.version>3.4.5</mybatis.version>
  </properties>

8. 部署Twossm_web的项目，只要把Twossm_web项目加入到tomcat服务器中即可

5. 编写实体类，在Twossm_domain项目中编写

在这里，我提醒一下，可能各位不熟悉idea快捷键，就比如说getset方法搞不出来哈哈，就这篇整合SSM的文章所用到的idea快捷键可以参考下面蓝色字体文章（点击蓝色字体即可），熟悉idea的哥们可以当我没说，当我在放pi（快快快捂住鼻子…）
IDEA快速实现接口、查找接口的实现、getSet方法快速生成等等常用快捷键

package com.gx.dao;

  
  

  
  

   
   
1
  
  

import com.gx.domain.Account;
import org.apache.ibatis.annotations.Insert;
import org.apache.ibatis.annotations.Select;
import org.springframework.stereotype.Repository;

import java.util.List;

public interface IAccountdao {

<span class="token keyword">public</span> List<span class="token operator">&lt;</span>Account<span class="token operator">&gt;</span> <span class="token function">findAll</span><span class="token punctuation">(</span><span class="token punctuation">)</span><span class="token punctuation">;</span>

package com.gx.service;

  
  

  
  

   
   
1
  
  

import com.gx.domain.Account;

import java.util.List;

public interface AccountService {
// 查询所有账户
public List<Account> findAll();

<span class="token comment">// 保存帐户信息</span>
<span class="token keyword">public</span> <span class="token keyword">void</span> <span class="token function">saveAccount</span><span class="token punctuation">(</span>Account account<span class="token punctuation">)</span><span class="token punctuation">;</span>

import com.gx.domain.Account;
import com.gx.service.AccountService;
import org.springframework.stereotype.Service;

import java.util.List;
@Service(“accountService”)
public class AccountServiceImpl implements AccountService {

<span class="token annotation punctuation">@Override</span>

到这里，整合环境就搭建好了效果如下，接下来搭建Spring的配置！

2、Spring框架代码的编写

搭建和测试Spring的开发环境

1、创建resources的资源文件目录管理XML配置文件

创建一个叫resources的资源文件目录，用来管理放置XML配置文件

2、编写applicationContext.xml的配置文件

在resources资源文件中创建applicationContext.xml的配置文件，编写具体的配置信息


applicationContext.xml中的配置信息

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"

3. 在项目中编写测试方法，进行测试

1、创建Test包


2、在test包中创建一个叫TestSpring的class类，具体的内容如下：

package com.gx.test;

  
  

  
  

   
   
1
  
  

import com.gx.domain.Account;
import com.gx.service.AccountService;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class TestSpring {
@Test
public void run1(){
ApplicationContext ac = new ClassPathXmlApplicationContext(“classpath:applicationContext.xml”);
AccountService as = (AccountService) ac.getBean(“accountService”);
as.findAll();
}
}

运行如下效果，说明搭建Spring的开发环境成功！

到这里，Spring的开发环境成功！接下来搭建SpringMVC框架环境。

3、SpringMVC框架代码的编写

搭建和测试SpringMVC的开发环境

1. 在web.xml中配置DispatcherServlet前端控制器

   <!--配置前端控制器-->
  <servlet>
     <servlet-name>dispatcherServlet</servlet-name>
      <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
      <!--加载springmvc.xml配置文件-->
      <init-param>
          <param-name>contextConfigLocation</param-name>
          <param-value>classpath:springmvc.xml</param-value>
      </init-param>
      <!--启动服务器，创建该servlet-->
      <load-on-startup>1</load-on-startup>
  </servlet>
    <servlet-mapping>
        <servlet-name>dispatcherServlet</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

2. 在web.xml中配置DispatcherServlet过滤器解决中文乱码

<!--解决中文乱码的过滤器-->
    <filter>
        <filter-name>characterEncodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>characterEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

4. 创建springmvc.xml的配置文件，编写配置文件

同样是在resources资源文件夹中创建springmvc.xml配置文件


springmvc.xml的配置文件内容：

<?xml version="1.0" encoding="UTF-8"?>

import com.gx.domain.Account;
import com.gx.service.AccountService;

这时候就要创建controller跳转的list.jsp页面了：




list.jsp页面创建好了，编写一下内容，只是看是否跳转成功，输出一句话即可：

6.部署Tomcat进行测试

7.测试运行

到这里，spring、springmvc的开发环境就都搭建好了，不容易啊，都坚持看到这里了，给你点个赞，接下来是整合spring和springmvc了！

4. Spring整合SpringMVC的框架

整合之前，想一想，怎样去整合Spring、SpringMVC框架呢，怎么才算是整合成功了呢，带着问题，一起来吧！

1、Spring整合SpringMVC的框架原理分析

整合成功的表现：在controller（SpringMVC）中能成功的调用service（Spring）对象中的方法。要想在controller中调用service方法，就要注入service到controller中来，有service对象才可以调用service方法，方法是这样没有错，但是有一个问题，就是启动Tomcat之后试想一下，在web.xml中配置有前端控制器，web容器会帮我们加载springmvc.xml配置文件，在springmvc.xml配置文件中我们配置情况是只扫描controller，别的不扫，而spring.xml文件就从头到尾没有执行过，spring中的配置扫描自然也不会去扫描，就相当于没有将spring交到IOC容器当中去，所以，现在的解决方案就是，在启动服务器时就加载spring配置文件,怎么实现呢？这时候监听器listener就派上用场了，具体实现如下：

2、在web.xml中配置ContextLoaderListener监听器

在项目启动的时候，就去加载applicationContext.xml的配置文件，在web.xml中配置ContextLoaderListener监听器（该监听器只能加载WEB-INF目录下的applicationContext.xml的配置文件）。要想加载applicationContext.xml的配置文件有两种方法，第一种（不建议）：

第二种（强烈建议）：在web.xml中配置加载路径

 <!--配置Spring的监听器，默认只加载WEB-INF目录下的applicationContext.xml配置文件-->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
 <!--设置配置文件的路径-->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>

  
  

  
  

  
  

   
   
1
   
   
2
   
   
3
   
   
4
   
   
5
   
   
6
   
   
7
   
   
8
   
   
9
  
  
  
  

   
   
1
   
   
2
   
   
3
   
   
4
   
   
5
   
   
6
   
   
7
   
   
8
   
   
9
  
  

至于为啥强烈建议第二种呢，是因为我们在整合过程中会有许多配置文件，我们自定义一个类似pages资源文件夹专门管理这些配置文件，方便管理，方便维护！！！

3. controller中注入service对象，调用service对象方法并测试

这时候，启动服务器时也会加载spring配置文件了，那么，我们可以在controller中注入service了，于是开始编写controller代码：

package com.gx.controller;

  
  

  
  

   
   
1
  
  

import com.gx.domain.Account;
import com.gx.service.AccountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import java.util.List;

@Controller
public class AccountController {

<span class="token annotation punctuation">@Autowired</span>   <span class="token comment">//按类型注入</span>
<span class="token keyword">private</span> AccountService accountService<span class="token punctuation">;</span>

<span class=“token annotation punctuation”>@RequestMapping</span><span class=“token punctuation”>(</span><span class=“token string”>"/account/findAll"</span><span class=“token punctuation”>)</span>
<span class=“token keyword”>public</span> String <span class=“token function”>findAll</span><span class=“token punctuation”>(</span>Model model<span class=“token punctuation”>)</span><span class=“token punctuation”>{</span>
System<span class=“token punctuation”>.</span>out<span class=“token punctuation”>.</span><span class=“token function”>println</span><span class=“token punctuation”>(</span><span class=“token string”>“Controller表现层：查询所有账户…”</span><span class=“token punctuation”>)</span><span class=“token punctuation”>;</span>

List<span class="token generics function"><span class="token punctuation"><</span>Account<span class="token punctuation">></span></span> list <span class="token operator">=</span> accountService<span class="token punctuation">.</span><span class="token function">findAll</span><span class="token punctuation">(</span><span class="token punctuation">)</span><span class="token punctuation">;</span>
<span class="token keyword">return</span> <span class="token string">"list"</span><span class="token punctuation">;</span>

<span class=“token punctuation”>}</span>

编写完成，开始测试，启动Tomcat，效果

到这里，
总算是整合完了spring、springmvc，同学你还能看到这里，我也挺欣慰的哈哈，手动再给你点个赞，接下来编写MyBatis环境惹！

5、MyBatis框架代码的编写

一看到Mybatis，就要想到dao，没错，MyBatis环境搭建首先是dao，搭建mybatis，之前要编写mapper映射的配置文件，其实挺麻烦的，所以我选择使用注解！

1、在IAccountdao接口方法上添加注解，编写SQL语句

package com.gx.dao;

  
  

  
  

   
   
1
  
  

import com.gx.domain.Account;
import org.apache.ibatis.annotations.Insert;
import org.apache.ibatis.annotations.Select;
import org.springframework.stereotype.Repository;

import java.util.List;

@Repository //此注解代表这是一个持久层，用法类似@controller、@service
public interface IAccountdao {

<span class="token annotation punctuation">@Select</span><span class="token punctuation">(</span><span class="token string">"select * from account"</span><span class="token punctuation">)</span>
<span class="token keyword">public</span> List<span class="token generics function"><span class="token punctuation">&lt;</span>Account<span class="token punctuation">&gt;</span></span> <span class="token function">findAll</span><span class="token punctuation">(</span><span class="token punctuation">)</span><span class="token punctuation">;</span>
<span class="token annotation punctuation">@Insert</span><span class="token punctuation">(</span><span class="token string">"insert into account (name,money) value(#{name},#{money})"</span><span class="token punctuation">)</span>
<span class="token keyword">public</span> <span class="token keyword">void</span> <span class="token function">saveAccount</span><span class="token punctuation">(</span>Account account<span class="token punctuation">)</span><span class="token punctuation">;</span>

2.创建SqlMapConfig.xml的配置文件并编写

和之前创建配置文件一样，创建：

编写：

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
    <environments default="mysql">
        <environment id="mysql">
            <transactionManager type="JDBC"/>
            <dataSource type="POOLED">
                <property name="driver" value="com.mysql.jdbc.Driver"/>
                <property name="url" value="jdbc:mysql:///ssm"/>
                <property name="username" value="root"/>
                <property name="password" value="root"/>
            </dataSource>
        </environment>
    </environments> 
    <!-- 使用的是注解 -->
    <mappers> 
        <!-- <mapper class="com.gx.dao.IAccountdao"/> --> <!-- 该包下所有的dao接口都可以使用 -->
        <package name="com.gx.dao"/>
    </mappers>
</configuration>

  
  

  
  

  
  

   
   
1

3

14
   
   
15
   
   
16
   
   
17
   
   
18
   
   
19
   
   
20
  
  
  
  

   
   
1
   
   
2
   
   
3
   
   
4
   
   
5

16
   
   
17
   
   
18
   
   
19
   
   
20
  
  

因为我使用的是注解，我觉得还是有必要提一下以下三种方法：

3. 创建并编写Mybatis测试方法

运行测试：

运行效果：

到这里，mybatis环境搭建算是完成了，，哈哈接下来搭建最后整合spring、mybatis！（估计看到这里，你也饿了吧）

6. Spring整合MyBatis框架

Spring整合MyBatis框架之前，先想一想，怎样才算整合成功呢？其实，这和之前的spring整合springMVC的套路差不多，其实就是，Service能成功调用dao对象，能够做查询操作或者新增数据能存进数据库。现在spring已经是在IOC容器中了，dao是一个接口，可以通过程序帮这个接口生成代理对象，我们要是可以把这个代理对象也放进IOC容器，那么service就可以拿到这个对象，之后在service中做一个注入，service从而调用dao代理对象的方法，那么我们怎么去实现dao接口生成的代理对象放入IOC容器呢？其实很简单，只需要如下操作！
整合目的：把SqlMapConfig.xml配置文件中的内容配置到applicationContext.xml配置文件中

1、在applicationContext.xml中配置数据库连接池

至于为啥要配池子，我不说大家应该也知道，毕竟各位都是学过ssm的大神了

<!--Spring整合MyBatis框架-->
    <!--配置连接池-->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="com.mysql.jdbc.Driver"/>
        <property name="jdbcUrl" value="jdbc:mysql:///ssm"/>
        <property name="user" value="root"/>
        <property name="password" value="root"/>
    </bean>

5
   
   
6
   
   
7

2、在applicationContext.xml中配置SqlSessionFactory工厂

没配置工厂之前，我们用Test测试的时候，每次都要先创建工厂，因为工厂能够给我们创建SqlSession,有了SqlSession就可以通过SqlSession拿到代理对象。现在我们直接在applicationContext.xml中配置SqlSessionFactory工厂，这就相当于IOC容器中有了工厂，就可以去创建SqlSession，进而通过SqlSession拿到代理对象，没必要每次测试都去创建工厂。

 <!--配置SqlSessionFactory工厂-->
<bean id="sqlSessonFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="dataSource"/>
 </bean>

2
   
   
3
   
   
4
  
  

3、在applicationContext.xml中配置IAccountdao接口所在包

因为工厂有了，SqlSession也有了，那代理谁呢，所以我们要配置IAccountdao接口所在包，告诉SqlSession去代理接口所在包中的代理，从而存到IOC容器中

 <!--配置IAccountdao接口所在包-->
<bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
    <property name="basePackage" value="com.gx.dao"/>
</bean>

2
   
   
3
   
   
4
  
  

4、小结上面的三个配置

其实，上面的操作就是把mybatis中的配置（SqlMapConfig.xml）转移到spring中去，让它产生代理并存到IOC容器中！

5、完善Service层代码

在AccountServiceImpl实现类中编写代码：

package com.gx.service.Impl;

  
  

  
  

   
   
1
  
  

import com.gx.dao.IAccountdao;
import com.gx.domain.Account;
import com.gx.service.AccountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;
@Service(“accountService”)
public class AccountServiceImpl implements AccountService {

<span class="token annotation punctuation">@Autowired</span>
<span class="token keyword">private</span> IAccountdao iaccountdao<span class="token punctuation">;</span>

<span class=“token annotation punctuation”>@Override</span>
<span class=“token keyword”>public</span> List<span class=“token generics function”><span class=“token punctuation”>&lt;</span>Account<span class=“token punctuation”>&gt;</span></span> <span class=“token function”>findAll</span><span class=“token punctuation”>(</span><span class=“token punctuation”>)</span> <span class=“token punctuation”>{</span>

<span class=“token keyword”>return</span> iaccountdao<span class=“token punctuation”>.</span><span class=“token function”>findAll</span><span class=“token punctuation”>(</span><span class=“token punctuation”>)</span><span class=“token punctuation”>;</span>
<span class=“token punctuation”>}</span>

<span class=“token annotation punctuation”>@Override</span>

<span class=“token punctuation”>}</span>

6、完善Controller层代码

package com.gx.controller;

  
  

  
  

   
   
1
  
  

import com.gx.domain.Account;
import com.gx.service.AccountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import java.util.List;

@Controller
public class AccountController {

<span class="token annotation punctuation">@Autowired</span>
<span class="token keyword">private</span> AccountService accountService<span class="token punctuation">;</span>

<span class=“token annotation punctuation”>@RequestMapping</span><span class=“token punctuation”>(</span><span class=“token string”>"/account/findAll"</span><span class=“token punctuation”>)</span>

7、完善list.jsp页面

8、运行测试

到这里，SSM整合就基本完成，各位可以去打王者楼喽，咳咳等等…还没完成，我只是说基本完成。
接下来，spring整合mybatis框架还需要配置事务（Spring的声明式事务管理），至于为啥，一张图告诉你！（哎呀…ai…ai…别打…别打…别打脸…）

7.spring整合mybatis框架配置事务（Spring的声明式事务管理）

细心的小伙伴可能发现了，我在整合spring、mybatis测试的时候（TestMybatis中），新增数据保存的时候手动的提交过事务 session.commit()，如果不写这一句，就会出现数据没提交的情况，因此为了完美的整合ssm，我们必须配置Spring的声明式事务管理！

1、在applicationContext.xml中配置Spring框架声明式事务管理

如果对一些execution表达式什么的不太清除的或者AOP不是特别印象深刻，可以去看看我的这篇文章【Spring框架学习总结二】Spring的AOP通俗理解以及AOP的入门开发

 <!--配置Spring框架声明式事务管理-->
    <!--配置事务管理器-->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource" />

3、完善Service层、Controller层代码

Service层：在AccountServiceImpl实现类中调用service中的saveAccount(account)方法

 @Override
    public void saveAccount(Account account) {
        System.out.println("Service业务层：保存帐户...");
        iaccountdao.saveAccount(account);  //调用service中的saveAccount(account)方法
    }

Controller层代码：在AccountController类中添加一个保存save的方法

    @RequestMapping("/account/save")
    public void save(Account account, HttpServletRequest request, HttpServletResponse response) throws IOException {
        accountService.saveAccount(account);
        response.sendRedirect(request.getContextPath()+"/account/findAll");
        return;
