大家好，我是雄雄，今天来带着大家来配置一下SSM(spring+springmvc+

mybatis)框架。

01

新建java web项目

直接在myeclipse中，新建一个web项目即可。

02

导入jar包

将SSM所需的jar包复制到项目的/WebRoot/WEB-INF/lib中，在这里我整理了下，大致需要34个jar文件，复制完之后，选中所有jar包，右击—Build Path-->Add to Build Path。

03

配置web.xml文件。

web.xml文件需要配置三部分信息，spring、springmvc以及解决springmvc传值乱码的过滤器，分别如下：

spring配置信息：

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

springmvc配置信息：

<servlet>    <servlet-name>springmvcservlet-name>    <servlet-class>org.springframework.web.servlet.DispatcherServletservlet-class>   <init-param>     <param-name>contextConfigLocationparam-name>     <param-value>classpath:springmvc-servlet.xmlparam-value>   init-param>   <load-on-startup>1load-on-startup>  servlet>  <servlet-mapping>    <servlet-name>springmvcservlet-name>    <url-pattern>/url-pattern>  servlet-mapping>

设置编码格式的过滤器信息：

  <filter>    <filter-name>encodingFilterfilter-name>    <filter-class>org.springframework.web.filter.CharacterEncodingFilterfilter-class>    <init-param>      <param-name>encodingparam-name>      <param-value>utf-8param-value>    init-param>    <init-param>      <param-name>forceEncodingparam-name>      <param-value>trueparam-value>    init-param>  filter>  <filter-mapping>    <filter-name>encodingFilterfilter-name>    <url-pattern>/*url-pattern>  filter-mapping>

04

配置Spring配置文件

applicationContext.xml文件，里面需要包含这些信息：用来连接数据库的数据源信息

  <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">    <property name="driverClassName" value="com.mysql.jdbc.Driver">property>    <property name="url" value="jdbc:mysql://localhost:3306/schooldb">property>    <property name="username" value="root">property>    <property name="password" value="root">property>  bean>

加载mybatis-config.xml文件以及sql映射文件的SqlSessionFactory：

  <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">    <property name="dataSource" ref="dataSource">property>    <property name="configLocation" value="classpath:mybatis-config.xml">property>    <property name="mapperLocations">      <list>        <value>classpath:org/dao/*.xmlvalue>      list>    property>  bean>

Mapper注入映射器的MapperScannerConfigurer：

  <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">    <property name="basePackage" value="org.dao">property>  bean>

最后就是扫描注解的配置：

  <context:component-scan base-package="org.dao,org.service,org.web"/>  <mvc:annotation-driven/>

05

配置springmvc的信息

springmvc-servlet.xml中需要包含最基本的两个部分，扫描注解和springmvc请求的前缀后缀设置：

  <context:component-scan base-package="org.web,org.dao,org.service"/>  <mvc:annotation-driven/>

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

06

配置mybatis配置文件

本文件简单点，就配置个别名和打印sql语句就行，都是可选的：

xml version="1.0" encoding="UTF-8" ?>br mpa-from-tpl="t"  />  PUBLIC "-//mybatis.org//DTD Config 3.0//EN"  "http://mybatis.org/dtd/mybatis-3-config.dtd"><configuration>

   <settings>

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

  <typeAliases>    <package name="org.entity"/>  typeAliases>

configuration>
