SSM文件配置


SSM(Spring Springmvc Mybatis)

说明:小学生所写,若有不足请指出

三大框架简单说明:

  Spring:经常使用的就是IOC(控制反转)和AOP编程,不需要使用new关键字,安全。

 Spring mvc:SpringMVC:它用于web层,相当于controller(等价于传统的servlet和struts的action),用来处理用户请求

  Mybatis:MyBatis  使用简单的  XML 或注解用于配置和原始映射,将接口和  Java   POJOs  Plain Old Java Objects ,普通的  Java对象)映射成数据库中的记录。


我的目录结构:




mysql.properties:

jdbc.driver=com.mysql.jdbc.Driver
  jdbc.url=jdbc\:mysql\://localhost\:3306/javaweb?useUnicode\=true&characterEncoding\=gbk
  jdbc.username=root
  jdbc.password=xidaojia


web.xml文件:

<?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">
	
	<welcome-file-list>
		<welcome-file>index.jsp</welcome-file>
	</welcome-file-list>
	       <!-- 配置前端控制器-->
	<servlet>
		<servlet-name>SpringMVC</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
                     <!--配置spring mvc加载的配置文件-->
		<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>
         <!-- 拦截器 若是*.do则只会拦截以.do结尾的请求-->
	<servlet-mapping>
		<servlet-name>SpringMVC</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>
	
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:spring-mybatis.xml</param-value>
	</context-param>
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
</web-app>
 
 
 
 

spring mvc.xml配置

<?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/mvc
              http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
              http://www.springframework.org/schema/beans
              http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
              http://www.springframework.org/schema/context
              http://www.springframework.org/schema/context/spring-context-3.0.xsd">

	<!-- 扫描所有的 controller -->
	<context:component-scan base-package="com.Controller" />

	<!-- 启动注解驱动 SpringMVC 功能 -->
	<mvc:annotation-driven />

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

</beans>
 
 

Spring-myatis.xml文件配置

这里面包含三种配置文件 ,分别对应数据层控制,业务逻辑层控制和事物的控制

数据层控制
          <!-- 配置数据库配置文件 -->
	<bean id="propertyConfigurer"
		class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
		<property name="location" value="classpath:mysql.properties" />
	</bean>

	<!-- 配置数据源  数据库和spring -->
	<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
		destroy-method="close">
		<property name="driverClassName" value="${jdbc.driver}" />
		<property name="url" value="${jdbc.url}" />
		<property name="username" value="${jdbc.username}" />
		<property name="password" value="${jdbc.password}" />
	</bean>
 
  
      Spring与Mybatis整合
    <!-- 配置sqlSessionFactory -->
	<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
		<property name="dataSource" ref="dataSource" />
		<!-- 自动扫描mapping.xml文件 是Mybatis的配置文件  -->
		<property name="mapperLocations" value="classpath:com/Dao/*.xml"></property>		
	</bean>
	<!-- DAO接口所在包名,Spring会自动查找其下的类 ,要求mapper的配置文件和类名一致-->
	<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
		<property name="basePackage" value="com.Dao" />
		<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
	</bean>
 
  
 
  
 
  
业务逻辑层:
 
  
           <!-- Spring注解   注入  prototype表示多例 -->
	<context:component-scan base-package="com.service" />
	<bean id="user" class="com.pojo.User" scope="prototype"/>
 
  
 
  
事务控制层;
 
  
           <!-- 事务管理器 -->
	<bean id="transactionManager"
		class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
		<property name="dataSource" ref="dataSource" />
	</bean>
 
  
 
  
 
  
 
  
 
  

整个spring-mybatis.xml配置文件为:

 
  
<?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:p="http://www.springframework.org/schema/p"
	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-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">
        <!-- Spring注解   注入  prototype表示多例 -->
	<context:component-scan base-package="com.service" />
	<bean id="user" class="com.pojo.User" scope="prototype"/>
	
	<!-- 配置数据库配置文件 -->
	<bean id="propertyConfigurer"
		class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
		<property name="location" value="classpath:mysql.properties" />
	</bean>

	<!-- 配置数据源  数据库和spring -->
	<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
		destroy-method="close">
		<property name="driverClassName" value="${jdbc.driver}" />
		<property name="url" value="${jdbc.url}" />
		<property name="username" value="${jdbc.username}" />
		<property name="password" value="${jdbc.password}" />
	</bean>

	<!-- 配置sqlSessionFactory  Mybatis配置-->
	<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
		<property name="dataSource" ref="dataSource" />
		<!-- 自动扫描mapping.xml文件 -->
		<property name="mapperLocations" value="classpath:com/Dao/*.xml"></property>		
	</bean>
	<!-- DAO接口所在包名,Spring会自动查找其下的类 -->
	<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
		<property name="basePackage" value="com.Dao" />
		<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
	</bean>

	<!-- 事务管理器 -->
	<bean id="transactionManager"
		class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
		<property name="dataSource" ref="dataSource" />
	</bean>
	
</beans>
 
  
以上只是对SSM框架简单实用的配置文件,如果需要深入了解,请参考官方文档。
