SSM配置文件整合流程
首先逆向工程生成Mapper以及pojodao层整合service层整合表现层整合web.xml配置
下面具体看每一层需要整合的东西 以下代码的头文件均已省略
Dao层整合
1、Mybatis核心配置文件
<?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>
这里不需要任何东西，因为交给spring管理
2、spring-dao配置文件
<!-- 数据库连接池 -->
<!-- 加载配置文件 -->
<context:property-placeholder location="classpath:properties/db.properties" />
<!-- 数据源 -->
<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>
<!-- 配置sqlSessionFactory -->
<bean class="org.mybatis.spring.SqlSessionFactoryBean" id="sqlSessionFactory">
<property name="configLocation" value="classpath:mybatis/SqlConfig.xml"></property>
<property name="dataSource" ref="dataSource"></property>
</bean>
<!-- 配置扫描包 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="包名"></property>
</bean>
db.properties
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/数据库名?characterEncoding=utf-8
jdbc.username=用户名
jdbc.password=用户密码
service层整合
1、spring-service整合
<!-- 配置扫描包 -->
<context:component-scan base-package="扫描包"/>
2、spring-trans整合
<!-- 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="切面表达式" />
</aop:config>
表现层整合
1、springMVC配置
<!-- 扫描包配置 -->
<context:component-scan base-package="包名" />
<!-- 注解驱动 -->
<mvc:annotation-driven />
<!-- 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>
<!-- 资源映射 -->
<mvc:resources location="/WEB-INF/css/" mapping="/css/**"/>
<mvc:resources location="/WEB-INF/js/" mapping="/js/**"/>
其中资源映射不是必须的，只是如果你的文件放在WEB-INF下面是无法访问的
Web.xml配置
<!-- 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>
</filter>
<filter-mapping>
<filter-name>CharacterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!-- springMVC前端控制器 -->
<servlet>
<servlet-name>自定义</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>自定义</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
以上就是ssm配置文件的一个整合了
