Maven整合SSM[详解图文]

一：新建maven工程，项目结构如下

具体步骤如下

1、 新建maven project 然后Next

 

选择maven-archetype-webapp然后Next

 

给项目一个坐标，然后Finish

 

创建后的项目有错--上面的工程名称是Demo3，这个截图不是，是因为为了重现错误，新建了一个工程

1、 给项目添加Tomcat

右键点击项目->Build Path->Configuer Build Path…->Add Library->Server Runtime->Apache Tomcat v7.0，OK

同样可以选8.0，因为这我只配置了7.0，所以选的7.0

1、 修改pom.xml文件，添加项目需要的jar文件

<properties> <!-- spring版本号 --> <spring.version>4.0.2.RELEASE</spring.version> <!-- mybatis版本号 --> <mybatis.version>3.2.6</mybatis.version> <!-- log4j日志文件管理包版本 --> <slf4j.version>1.7.7</slf4j.version> <log4j.version>1.2.17</log4j.version> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.11</version> <!-- 表示开发的时候引入，发布的时候不会加载此包 --> <scope>test</scope> </dependency> <!-- spring核心包 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-oxm</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${spring.version}</version> </dependency> <!-- mybatis核心包 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>${mybatis.version}</version> </dependency> <!-- mybatis/spring包 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.2.2</version> </dependency> <!-- 导入java ee jar 包 --> <dependency> <groupId>javax</groupId> <artifactId>javaee-api</artifactId> <version>7.0</version> </dependency> <!-- 导入Mysql数据库链接jar包 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.30</version> </dependency> <!-- 导入dbcp的jar包，用来在applicationContext.xml中配置数据库 --> <dependency> <groupId>commons-dbcp</groupId> <artifactId>commons-dbcp</artifactId> <version>1.2.2</version> </dependency> <!-- JSTL标签类 --> <dependency> <groupId>jstl</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <!-- 日志文件管理包 --> <!-- log start --> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>${log4j.version}</version> </dependency> <!-- 格式化对象，方便输出日志 --> <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.1.41</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>${slf4j.version}</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>${slf4j.version}</version> </dependency> <!-- log end --> <!-- 映入JSON --> <dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-mapper-asl</artifactId> <version>1.9.13</version> </dependency> <!-- 上传组件包 --> <dependency> <groupId>commons-fileupload</groupId> <artifactId>commons-fileupload</artifactId> <version>1.3.1</version> </dependency> <dependency> <groupId>commons-io</groupId> <artifactId>commons-io</artifactId> <version>2.4</version> </dependency> <dependency> <groupId>commons-codec</groupId> <artifactId>commons-codec</artifactId> <version>1.9</version> </dependency> </dependencies>

当修改完pom.xml后，项目帮我们下载需要使用的jar包，如下：

 右键项目->maven->update Project，选中Force Update of Snapshots/Releases选项，OK

 

更新后，发现项目报红叉:

 

说明： faces 2.2 必须使用动态Web模块2.5或者以上，必须使用java 1.6或者以上

这时我们右键项目->Project Facets，发现Dynamic Web Module是2.3，Java是1.5

我们在更改Dynamic Web Module时发现不让修改，修改步骤如下：

1） 改项目下的.settings\org.eclipse.wst.common.project.facet.core.xml，将 版本改成为3.0,将成后是 <installed facet="jst.web" version="3.0"/> ，再启动Eclipse.右键项目->Maven->Update Project

2） 此时，问题一般解决。如还不能解决，尝试在pom.xml中加入如下代码

finalName中间填写自己的项目名

<build> <finalName>maven_ssm</finalName> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>2.0.2</version> <configuration> <source>1.6</source> <target>1.6</target> </configuration> </plugin> </plugins> </build>

更新maven，此时发现还有错误，在eclipse的Markers窗口视图装其报错选项删除掉即可！

 

1、 查看maven的配置是否已经修改

1) Java编译器配置

右键项目->Properties->Java Compiler->JDK Compliance level: 1.6看看是否已经更改成1.6

 

删除自带的jre路径，点击Java Build Path设置为我们自己安装的jre6的路径

 

 

2) 查看Project Facets，是否如下：

Dynamic Web Module:3.0

Java : 1.6

JavaScript:1.0

JavaServer Faces:2.2

JAX-RS(REST Web Services) : 2.0

 

现在maven基本已经配置完成

下面创建SSM项目

在SQL数据库创建表

1、 在com.yztc.po下创建User类

package com.yztc.po; public class User { private int id; private String user_name; private int age; private String remark; public int getId() { return id; } public void setId(int id) { this.id = id; } public void setUser_name(String user_name) { this.user_name = user_name; } public String getUser_name() { return user_name; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } public String getRemark() { return remark; } public void setRemark(String remark) { this.remark = remark; } @Override public String toString() { return "["+id+","+user_name+","+age+","+remark+"]"; } }

 

2、 在com.yztc.mapper下创建UserMapper接口

package com.yztc.mapper; import java.util.List; import com.yztc.po.User; public interface UserMapper { public List<User> findAll(); }

 

3、 在com.yztc.mapper下创建UserMapper.xml

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <mapper namespace="com.yztc.mapper.UserMapper"> <select id="findAll" resultType="com.yztc.po.User"> select * from user; </select> </mapper>

 

4、 在com.yztc.service下创建UserService接口

package com.yztc.service; import java.util.List; import com.yztc.po.User; public interface UserService { public List<User> findAll(); }

 

5、 在com.yztc.serviceImpl下创建UserServiceImpl类

package com.yztc.serviceImpl; import java.util.List; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import com.yztc.mapper.UserMapper; import com.yztc.po.User; import com.yztc.service.UserService; @Service("userService") public class UserServiceImpl implements UserService { @Autowired public UserMapper userMapper; @Override public List<User> findAll() { return userMapper.findAll(); } }

 

6、 在src/main/resources下创建项目配置文件applicationContext.xml

<?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:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd"> <!-- 1.扫描组件 --> <context:annotation-config/> <context:component-scan base-package="com.yztc" /> <!-- spring-ajax注释必须加上这句 --> <mvc:annotation-driven/> <!-- 2.连接池的配置 --> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"> <property name="driverClassName" value="com.mysql.jdbc.Driver"/> <property name="url" value="jdbc:mysql://localhost:3306/test"/> <property name="username" value="root"/> <property name="password" value="123456"/> </bean> <!-- 2.使用引入的配置文件连接位置 新建文件jdbc.properties，内容 dbcp.driver=com.mysql.jdbc.Driver dbcp.url=jdbc:mysql://localhost:3306/test dbcp.username=root dbcp.password=123456 <context:property-placeholder location="classpath:jdbc.properties" /> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"> <property name="driverClassName" value="${dbcp.driver}"/> <property name="url" value="${dbcp.url}"/> <property name="username" value="${dbcp.username}"/> <property name="password" value="${dbcp.password}"/> </bean> --> <!-- 3.配置事务 --> <bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource"/> </bean> <!-- 扫描关于事务的注释，此事务注释作用于dataSource数据源 --> <tx:annotation-driven transaction-manager="txManager"/> <!-- 4.SqlSessionFactory --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource"/> </bean> <!-- 5.MapperScannerConfigurer --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.yztc.mapper" /> </bean> </beans>

 

7、 修改web.xml文件

<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0"> <display-name>Archetype Created Web Application</display-name> <!-- 在servlet之前进行请求的过滤 --> <filter> <filter-name>springUtf8Encoding</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> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>springUtf8Encoding</filter-name> <url-pattern>/</url-pattern> </filter-mapping> <servlet> <servlet-name>springmvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> </web-app>

 

8、 在Deployed Resources下webapp下创建一个index.jsp

<html> <head> <meta charset="utf-8"/> <title>MAVEN-SSM</title> </head> <body> <button id="btn" onclick="findByNameUser()">press</button> <div id="box"></div> <script type="text/javascript"> var un = document.getElementById("btn"); function findByNameUser(){ var xmlHttp = null; if(window.XMLHttpRequest){ xmlHttp = new XMLHttpRequest(); }else{ xmlHttp = new ActiveXObject("Microsoft.XMLHTTP"); } xmlHttp.onreadystatechange = function(){ if(xmlHttp.status == 200 && xmlHttp.readyState == 4){ var box = document.getElementById("box"); var user = eval("("+xmlHttp.responseText +")"); for(var i=0;i<user.length;i++) { box.innerHTML += "ID="+user[i]["id"] +",NAME="+user[i]["user_name"]+",AGE="+user[i]["age"]+",REMARK="+user[i]["remark"]+"<br/>"; } } } xmlHttp.open("get", "findAll", true); xmlHttp.send(); } </script> </body> </html>

 

9、 在com.yztc.controller下创建UserController类

package com.yztc.controller; import java.util.List; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.ResponseBody; import com.yztc.po.User; import com.yztc.service.UserService; @Controller public class UserController { @Autowired public UserService userService; @RequestMapping("/findAll") public @ResponseBody List<User> findAll(){ List<User> users = userService.findAll(); return users; } }

 

10、 项目右键，Run As on Server

总结步骤：

一：搭建Maven环境

jar包的引入在pom.xml中实现

二：

Web.xml--存放路径有变化

applicationContext.xml--存放路径有变化

SSM项目整体结构不变，只是jar包的引入是在webContent下面的lib，现在变成在Maven的pom.xml中引入
