ssm项目集成步骤

第一步：整合dao层
mybatis 和 spring ，通过 spring 管理 mapper 接口。
使用 mapper 的扫描器自动扫描 mapper 接口 在spring中进行注册。

MConfig.xml

<configuration>

    
    <settings>
   
        <setting name="logImpl" value="LOG4J"/>

        
        
        

       
        <setting name="cacheEnabled" value="true"/>
    settings>

    
    <typeAliases>
        
        <package name="com.demo.ssm.po"/>
    typeAliases>

    
    <mappers>
        
        
        


        <package name="com.demo.ssm.mapper"/>

    mappers>
configuration>

applicationContext-dao.xml

配置数据源
配置sqlSessionFactory
配置mapper扫描器

    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        
        <property name="driverClass" value="${jdbc.driver}"/>
        
        <property name="jdbcUrl" value="${jdbc.url}"/>
        
        <property name="user" value="${jdbc.username}"/>
        
        <property name="password" value="${jdbc.password}"/>
    bean>


    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">

    bean>


    
    
    
        
        
        
    

    
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        
        
        
        
        <property name="basePackage" value="com.demo.ssm.mapper"/>

        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
    bean>
beans>

逆向工程生产po类mapper（单表CRUD）
mybatis-generator.xml

<generatorConfiguration>
    <context id="testDb">
        
        <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost:3306/mdb" userId="root" password="root">jdbcConnection>

        
        <javaModelGenerator targetPackage="com.demo.ssm.po" targetProject=".\src\main\java">javaModelGenerator>


        
        <sqlMapGenerator targetPackage="com.demo.ssm.mapper" targetProject=".\src\main\java">sqlMapGenerator>

        
        <javaClientGenerator type="XMLMAPPER" targetPackage="com.demo.ssm.mapper" targetProject=".\src\main\java">javaClientGenerator>


        
        <table tableName="item">table>
        <table tableName="user">table>
        <table tableName="orderdetail">table>
        <table tableName="orders">table>

    context>
generatorConfiguration>        

Generator.java

public class Generator {
    public void generator() throws IOException, XMLParserException, InvalidConfigurationException, SQLException, InterruptedException {
        List warnings = new ArrayList();
        boolean overwrite = true;
        File configFile = new File("src/main/resources/generator/generatorConfig.xml");
        ConfigurationParser parser = new ConfigurationParser(warnings);
        Configuration configuration = parser.parseConfiguration(configFile);
        DefaultShellCallback callback = new DefaultShellCallback(overwrite);
        MyBatisGenerator myBatisGenerator = new MyBatisGenerator(configuration,callback,warnings);
        myBatisGenerator.generate(null);
    }

    public static void main(String[] args) throws InterruptedException, SQLException, InvalidConfigurationException, XMLParserException, IOException {
        Generator generator = new Generator();

        generator.generator();
    }
}

第二步：整合service层
通过 spring 管理 service 接口。
使用配置方式将 service 接口配置在 spring 配置文件中。
实现事务控制

定义service接口

public interface ItemsService {
    //商品查询列表
    List findItemsList(ItemsQueryVo itemsQueryVo);
}

实现service接口

public class ItemsServiceImpl implements ItemsService {
    @Autowired
    private ItemsMapperCustom itemsMapperCustom;

    public List findItemsList(ItemsQueryVo itemsQueryVo) {

        return itemsMapperCustom.findItemsList(itemsQueryVo);
    }
}

service配置
applicationContext-service

<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"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.3.xsd
    http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd
    http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd"
>

    
    <bean class="com.demo.ssm.service.impl.ItemsServiceImpl">
    bean>
beans>

service事务声明
applicationContext-tranaction.xml

<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"
       xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.3.xsd
    http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd
    http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd"
>

    
    
    <bean class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        
        <property name="dataSource" ref="dataSource">property>
    bean>

    
    <tx:advice id="txAdvice" transaction-manager="transactionManager">
        <tx:attributes>
            <tx:method name="save*" propagation="REQUIRED"/>
            <tx:method name="delete*" propagation="REQUIRED"/>
            <tx:method name="insert" propagation="REQUIRED"/>
            <tx:method name="update*" propagation="REQUIRED"/>
            <tx:method name="find*" propagation="SUPPORTS" read-only="true"/>
            <tx:method name="get*" propagation="SUPPORTS" read-only="true"/>
            <tx:method name="sel*" propagation="SUPPORTS" read-only="true"/>
        tx:attributes>
    tx:advice>

    
    <aop:config>
        <aop:advisor advice-ref="txAdvice" pointcut="execution(* com.demo.ssm.service.impl.*.*(..))"/>
    aop:config>
beans>

第三步：整合springmvc
由于 springmvc 是 spring 的模块 ， 不需要整合。
创建 springmcv.xml，配置处理器映射器，适配器，视图解析器
springmvc.xml

<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"
       xmlns:tx="http://www.springframework.org/schema/tx" xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.3.xsd
    http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd
    http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd"
>

    
    

    
    <context:component-scan base-package="com.demo.ssm.controller">context:component-scan>

    


    
    
    

    

    
    
    

    


    
    <mvc:annotation-driven>mvc:annotation-driven>


    
    
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
    bean>
beans>

配置前端控制器
web.xml

<web-app>
  <display-name>Archetype Created Web Applicationdisplay-name>
  
  <context-param>
    <param-name>contextConfigLocationparam-name>
    <param-value>classpath:spring/applicationContext-*.xmlparam-value>
  context-param>
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListenerlistener-class>
  listener>

  <servlet>
    <servlet-name>springmvcservlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServletservlet-class>
    
    <init-param>
      <param-name>contextConfigLocationparam-name>
      <param-value>classpath:springmvc.xmlparam-value>
    init-param>
  servlet>


  <servlet-mapping>
    <servlet-name>springmvcservlet-name>
    
    <url-pattern>*.actionurl-pattern>
  servlet-mapping>

web-app>

编写Controller（handler）
ItemsController.java

@Controller
public class ItemsController {
    @Autowired
    private ItemsService  itemsService;


    //商品查询列表
    @RequestMapping("/queryItems")
    public ModelAndView queryItems(){
        List list = itemsService.findItemsList(null);

        ;

        //返回modelAndView
        ModelAndView modelAndView = new ModelAndView();

        //相当于request的setAttr,在jsp通过itemlist获取数据
        modelAndView.addObject("itemsList",list);

        //指定试图
        //试图解析器中配置了前缀和后缀
//        modelAndView.setViewName("WEB-INF/jsp/itemsList.jsp");
        modelAndView.setViewName("itemsList");

        return modelAndView;

编写jsp

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@page isELIgnored="false" pageEncoding="UTF-8" %>
<%--
  Created by IntelliJ IDEA.
  User: v7

  Time: 12:18
  To change this template use File | Settings | File Templates.
--%>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>ItemsListtitle>
head>
<body>
    <from action="${pageContext.request.contextPath }/item/queryItem.action" method="post">
        查询条件：
        <table width="100%" border="1">
            <tr>
                <td><input type="submit" value="查询"/>td>
            tr>
        table>
        商品列表：
        <table width="100%" border="1">
            <tr>
                <th>商品名称th>
                <th>商品价格th>
                <th>生产日期th>
                <th>商品描述th>
                <th>操作th>
            tr>
            <c:forEach items="${itemsList}" var="item">
                <tr>
                    <td>${item.name}td>
                    <td>${item.price}td>
                    <td>${item.createTime}td>
                    <td>${item.detail}td>
                    <td><a href="${pageContext.request.contextPath}/item/editItem.action?id=${item.id}">修改a>td>
                tr>

            c:forEach>
        table>
    from>
body>
html>

加载spring容器
将mapper,service,controller加载到spring中

建议使用通配符方法加载spring文件.
在web.xml中，添加spring容器

  <context-param>
    <param-name>contextConfigLocationparam-name>
    <param-value>classpath:spring/applicationContext-*.xmlparam-value>
  context-param>
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListenerlistener-class>
  listener>

所需要的jar包：
数据库驱动包：mysql-5.1
mybatis 的jar包
mybatis 和 spring 整合包
log4j 包
数据库连接池包 c3p0
