SSM框架的整合

首先先上干货，先把文件代码贴上来。

1.mybatis-config.xml

<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE configurationPUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"><configuration><settings><!-- 开启驼峰式命名 --><setting name="mapUnderscoreToCamelCase" value="true" /></settings></configuration>

2.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: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.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsdhttp://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd"><!-- 配置扫描包 --><!-- 此处的包的地址需要根据实际修改 设置手动扫描Controller包和ControllerAdvice包 --><context:component-scan base-package="com.gpf.ssm" use-default-filters="false"><context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/><context:include-filter type="annotation" expression="org.springframework.web.bind.annotation.ControllerAdvice"/></context:component-scan><!-- 配置视图解析器 --><bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"><property name="prefix" value="/WEB-INF/views/"></property><property name="suffix" value=".jsp"></property></bean><!--设置可以访问静态资源 否则文件无法访问 --><mvc:default-servlet-handler /><!-- 设置view-controller之后，不设置此方法之前的RequestMapping方法设置的URL无法访问 --><mvc:annotation-driven></mvc:annotation-driven></beans>

至于为什么要手动扫描包，在之前的博客中有提到。博客地址：http://blog.csdn.net/gpf951101/article/details/77774974

需更改位置：1 即扫描包

3.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: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.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsdhttp://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd"><!-- 配置扫描包 --><!-- 配置扫描包 此处需要根据实际更改扫描包 --><context:component-scan base-package="com.gpf.ssm" use-default-filters="true"><context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/><context:exclude-filter type="annotation" expression="org.springframework.web.bind.annotation.ControllerAdvice"/></context:component-scan><!-- 加载数据库文件 根据实际情况进行配置 --><context:property-placeholder location="classpath:db.properties"/><!-- 获取信息 --><bean id="comboPooledDataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"><property name="user" value="${jdbc.username}"></property><property name="password" value="${jdbc.password}"></property><property name="jdbcUrl" value="${jdbc.url}"></property><property name="driverClass" value="${jdbc.driver}"></property></bean><!-- 配置JdbcTemplate --><bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate"><property name="dataSource" ref="comboPooledDataSource"></property></bean><!-- 配置参数名的Template --><bean id="namedParameterJdbcTemplate" class="org.springframework.jdbc.core.namedparam.NamedParameterJdbcTemplate"><constructor-arg name="dataSource" ref="comboPooledDataSource"></constructor-arg></bean><!-- 配置事务 --><bean id="dataSourceTransactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"><property name="dataSource" ref="comboPooledDataSource"></property></bean><!-- 加载事务  --><tx:annotation-driven transaction-manager="dataSourceTransactionManager"/><!-- 配置 SqlSessionFactory --><bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"><property name="dataSource" ref="comboPooledDataSource" /><!-- 配置 mybatis 配置文件的位置和名称 根据实际配置位置 --><property name="configLocation" value="classpath:mybatis-config.xml"></property></bean><!-- 扫描 Mapper 接口，并把它们纳入到 IOC 容器中  根据实际配置包--><bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"><property name="basePackage" value="com.gpf.ssm.mapper" /></bean></beans>

需要更改位置：至少四处，均为配置文件位置和包的名称。

4.db.properties

jdbc.driver=com.mysql.jdbc.Driverjdbc.url=jdbc:mysql://localhost:3306/mybatis?characterEncoding=utf8&useSSL=true&&rewriteBatchedStatements=truejdbc.username=rootjdbc.password=951101

5.web.xml

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">  <display-name>ssm</display-name>  <!-- 配置Spring -->  <!-- needed for ContextLoaderListener --><context-param><param-name>contextConfigLocation</param-name><!-- 此处为Spring的xml配置文件的路径 需要更改 classpath代表根目录 --><param-value>classpath:applicationContext.xml</param-value></context-param><!-- Bootstraps the root web application context before servlet initialization --><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><!-- 配置SpringMVC --><!-- The front controller of this Spring Web application, responsible for handling all application requests --><servlet><servlet-name>springDispatcherServlet</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><param-name>contextConfigLocation</param-name><param-value>classpath:springmvc.xml</param-value></init-param><load-on-startup>1</load-on-startup></servlet><!-- Map all requests to the DispatcherServlet for handling --><servlet-mapping><servlet-name>springDispatcherServlet</servlet-name><url-pattern>/</url-pattern></servlet-mapping>  <!-- 配置字符编码过滤器  --><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><!-- POST转PUT和DELETE --><filter><filter-name>HiddenHttpMethodFilter</filter-name><filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class></filter><filter-mapping><filter-name>HiddenHttpMethodFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping></web-app>

配置Spring和SpringMVC，注意修改文件位置。

配置文件设置完毕。

如上。操作完毕。

最后附上ssm所需要的jar包，需要保证版本，不然会容易报错。
