搭建spring springMVC mybatis 项目

自己配置了一个SSM框架,打算做个小网站,这里把SSM的配置流程详细的写了出来,方便很少接触这个框架的朋友使用,文中各个资源均免费提供!

一.创建web项目(eclipse)

 File-->new-->Dynamic Web Project (这里我们创建的项目名为SSM)

下面是大致目录结构

 

二. SSM所需jar包。

 jar包链接:https://pan.baidu.com/s/1dTClhO 密码:n4mm

三.整合开始

1.mybatis配置文件(resource/mybatis/SqlMapConfig.xml)

<?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>
 
</configuration>
 

2.Dao,mybatis整合spring,通过spring管理SqlSessionFactory、mapper代理对象(resource/spring/applicationContext-dao.xml)

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"
    xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.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
    http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd">
 
    <!-- 数据库连接池 -->
    <!-- 加载配置文件 -->
    <context:property-placeholder location="classpath:*.properties" />
    <!-- 数据库连接池 -->
    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"
        destroy-method="close">
        <property name="url" value="${jdbc.url}" />
        <property name="username" value="${jdbc.username}" />
        <property name="password" value="${jdbc.password}" />
        <property name="driverClassName" value="${jdbc.driver}" />
        <property name="maxActive" value="10" />
        <property name="minIdle" value="5" />
    </bean>
    <!-- 让spring管理sqlsessionfactory 使用mybatis和spring整合包中的 -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <!-- 数据库连接池 -->
        <property name="dataSource" ref="dataSource" />
        <!-- 加载mybatis的全局配置文件 -->
        <property name="configLocation" value="classpath:mybatis/SqlMapConfig.xml" />
    </bean>
    <!-- 自动扫描 将Mapper接口生成代理注入到Spring -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.mapper" />
    </bean>
</beans>
这里用的是阿里的连接池,当然也可以用c3p0,个人建议用阿里

3. 所有的实现类都放到spring容器中管理。由spring创建数据库连接池,并有spring管理实务。(resource/spring/applicationContext-service.xml)

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"
    xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.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
    http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd">
        
        <!-- spring自动去扫描base-pack下面或者子包下面的java文件-->
        <!--管理Service实现类-->
        <context:component-scan base-package="com.service"/>
        .
</beans>

配置spring管理实务 (resource/spring/applicationContext-trans.xml)

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"
    xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.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
    http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd">
    <!-- 事务管理器 -->
    <bean id="transactionManager"
        class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <!-- 数据源 -->
        <property name="dataSource" ref="dataSource" />
    </bean>
    <!-- 通知 -->
    <tx:advice id="txAdvice" transaction-manager="transactionManager">
        <tx:attributes>
            <!-- 传播行为 -->
            <tx:method name="save*" propagation="REQUIRED" />
            <tx:method name="insert*" propagation="REQUIRED" />
            <tx:method name="add*" propagation="REQUIRED" />
            <tx:method name="create*" propagation="REQUIRED" />
            <tx:method name="delete*" propagation="REQUIRED" />
            <tx:method name="update*" propagation="REQUIRED" />
            <tx:method name="find*" propagation="SUPPORTS" read-only="true" />
            <tx:method name="select*" propagation="SUPPORTS" read-only="true" />
            <tx:method name="get*" propagation="SUPPORTS" read-only="true" />
        </tx:attributes>
    </tx:advice>
    <!-- 切面 -->
    <aop:config>
        <aop:advisor advice-ref="txAdvice"
            pointcut="execution(* com.service.*.*(..))" />
    </aop:config>
</beans>
 

4. Springmvc整合spring框架,由springmvc管理controller(resource/spring/springmvc.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:p="http://www.springframework.org/schema/p"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
    
    <!-- 扫描controller -->
    <context:component-scan base-package="com.controller" />
    
    <!-- Spring 来扫描指定包下的类,并注册被@Component,@Controller,@Service,@Repository等注解标记的组件 -->
    <mvc:annotation-driven />
    
    <!-- 配置SpringMVC的视图解析器-->
    <bean
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/" />
        <property name="suffix" value=".jsp" />
    </bean>
</beans>
 

5. 2中加载的属性配置文件(dbconfig.properties)根据自己的数据库更改用户名密码以及库

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/test1?characterEncoding=utf-8
jdbc.username=root
jdbc.password=123456
6. 配置log4j

log4j.properties

log4j.rootLogger=error,CONSOLE,A
log4j.addivity.org.apache=false
 
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.Threshold=error
log4j.appender.CONSOLE.layout.ConversionPattern=%d{yyyy-MM-dd HH\:mm\:ss} -%-4r [%t] %-5p  %x - %m%n
log4j.appender.CONSOLE.Target=System.out
log4j.appender.CONSOLE.Encoding=gbk
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
 
 
log4j.appender.A=org.apache.log4j.DailyRollingFileAppender  
log4j.appender.A.File=${catalina.home}/logs/FH_log/PurePro_
log4j.appender.A.DatePattern=yyyy-MM-dd'.log'
log4j.appender.A.layout=org.apache.log4j.PatternLayout  
log4j.appender.A.layout.ConversionPattern=[FH_sys]  %d{yyyy-MM-dd HH\:mm\:ss} %5p %c{1}\:%L \: %m%n
 
 (log4j.xml)

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration PUBLIC "-//APACHE//DTD LOG4J 1.2//EN" "log4j.dtd">
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">
 
    <!-- Appenders -->
    <appender name="console" class="org.apache.log4j.ConsoleAppender">
        <param name="Target" value="System.out" />
        <layout class="org.apache.log4j.PatternLayout">
            <param name="ConversionPattern" value="%d{yyyy HH:mm:ss} %-5p %c - %m%n" />
        </layout>
    </appender>
    
    <!-- Application Loggers -->
    <logger name="com">
        <level value="error" />
    </logger>
    
    <!-- 3rdparty Loggers -->
    <logger name="org.springframework.core">
        <level value="error" />
    </logger>    
    
    <logger name="org.springframework.beans">
        <level value="error" />
    </logger>
    
    <logger name="org.springframework.context">
        <level value="error" />
    </logger>
 
    <logger name="org.springframework.web">
        <level value="error" />
    </logger>
 
    <logger name="org.springframework.jdbc">
        <level value="error" />
    </logger>
 
    <logger name="org.mybatis.spring">
        <level value="error" />
    </logger>
    <logger name="java.sql">
        <level value="error" />
    </logger>
    <!-- Root Logger -->
    <root>
        <priority value="error" />
        <appender-ref ref="console" />
    </root>
    
</log4j:configuration>

7、 配置 web.xml 

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    id="WebApp_ID" version="2.5">
    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>
    <!-- 加载spring容器 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring/applicationContext*.xml</param-value>
    </context-param>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <!-- 解决post乱码 -->
    <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>
        <!-- <init-param>
            <param-name>forceEncoding</param-name>
            <param-value>true</param-value>
        </init-param> -->
    </filter>
    <filter-mapping>
        <filter-name>CharacterEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>


    <!-- springmvc的前端控制器 -->
<!--     <servlet>
        <servlet-name>taotao-manager</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        contextConfigLocation不是必须的, 如果不配置contextConfigLocation, springmvc的配置文件默认在:WEB-INF/servlet的name+"-servlet.xml"
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:spring/springmvc.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>SSM</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-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:spring/springmvc.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>

 SSM框架整合完成,至于mybatis逆向工程生成的mapper.xml和pojo请放到第一张图的目录下

逆向工程项目我会贴出链接,解压导入改路径运行main方法就会自动生成了,注意配置生成的路径

逆向工程链接: 链接:https://pan.baidu.com/s/1ht4x3jI 密码:tvad

到这里项目整合完成,接下来是测试!

UserController.java

package com.controller;
 
import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import com.pojo.User;
import com.service.UserService;
 
@Controller
@RequestMapping("/user")  
public class UserController {
    
    @Resource(name="userService")
    private UserService userService;
    /**
     * 根据id查询
     */
    @RequestMapping(value="/queryById")
    public ModelAndView queryById(HttpServletRequest request){
        ModelAndView mv = new ModelAndView();
        String id = request.getParameter("id");
        try{
            User var = userService.findById(id);
            mv.setViewName("index");
            mv.addObject("var", var);
        } catch(Exception e){
        }
        return mv;
    }
}

UserService.java

package com.service;
 
import javax.annotation.Resource;
 
import org.springframework.stereotype.Service;
 
import com.mapper.UserMapper;
import com.pojo.User;
 
@Service("userService")
public class UserService {
    @Resource
    private UserMapper dao;
    /*
    * 通过id获取数据
    */
    public User findById(String id)throws Exception{
        return (User)dao.selectByPrimaryKey(id);
    }
}
 

为节省篇幅,更快的搭建成功,这里只写了一个方法,根据id查询数据

request -- > WebContent/index.jsp

<%@ page language="java" contentType="text/html; charset=utf-8"
    pageEncoding="utf-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<%
    String path = request.getContextPath();
    String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

</head>
<body>
    <form action="user/queryById.do" method="post">
        输入要查询的id:    <input type="text" name="id" value="123456"/>
        <button type="submit">提交</button>
    </form>
</body>
</html>

    }
</style>
</head>
<body>
<%
    User user = ((User)request.getAttribute("var"));
%>
 
    <table class="table">
        <tr class="td">
            <td>ID</td>
            <td>用户名</td>
            <td>密码</td>
            <td style="width: 200px">公司</td>
            <td>年龄</td>
            <td>性别</td>
        </tr>
<%if(user!=null){%>
        <tr class="td">
            <td><%=user.getId()%></td>
            <td><%=user.getUsername()%></td>
            <td><%=user.getPassword()%></td>
            <td><%=user.getCompany()%></td>
            <td><%=user.getAge()%></td>
            <td><%=user.getSex()==1?"男":"女"%></td>
        </tr>
    <%}else{ %>
        <tr class="td">
            <td style="color: red;">暂无相关数据</td>
        </tr>
<%} %>
    </table>
 
</body>
</html>
