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.ContextLoaderListener</listener-class>
-
</listener>
-
<context-param>
-
<param-name>contextConfigLocation</param-name>
-
<param-value>classpath:applicationContext.xml</param-value>
-
</context-param>
springmvc配置信息：
-
<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:springmvc-servlet.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>
设置编码格式的过滤器信息：
-
<!-- 解决springmvc传递值乱码问题 -->
-
<filter>
-
<filter-name>encodingFilter</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>encodingFilter</filter-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
-
<!-- 配置数据源-->
-
<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：
-
<!--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
/*.xml</value>
-
</list>
-
</property>
-
</bean>
Mapper注入映射器的MapperScannerConfigurer：
-
<!-- 配置自动映射器 -->
-
<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：
-
<!-- 扫描所有注解信息 -->
-
<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：
-
<!-- 扫描注解 -->
-
<context:component-scan base-
package=
"org.web,org.dao,org.service"/>
-
<mvc:annotation-driven/>
-
-
<!-- 配置前缀和后缀 -->
-
<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" ?>
-
<!DOCTYPE configuration
-
PUBLIC
"-//mybatis.org//DTD Config 3.0//EN"
-
"http://mybatis.org/dtd/mybatis-3-config.dtd">
-
<configuration>
-
-
<settings>
-
<!-- 打印sql语句 -->
-
<setting name=
"logImpl" value=
"STDOUT_LOGGING" />
-
</settings>
-
<!-- 起别名 -->
-
<typeAliases>
-
<
package name=
"org.entity"/>
-
</typeAliases>
-
-
</configuration>
