SSM环境搭建回顾

编辑器：IDEA

系统：Win 10

包管理：maven

SSM：SpringMvc、Spring、MyBatis

一、搭建 maven的父子工程

  • 先建立 ssm 的父工程 review_ssm

  • 再分别建立 domain、dao、service、utils子模块，以及最后创建使用maven的webapp骨架构建的 web模块

构建 web骨架的时候记得补全目录

二、导包

在父工程中导入相关的依赖。

    <properties>
        <spring.version>5.0.2.RELEASE</spring.version>
        <slf4j.version>1.6.6</slf4j.version>

        <oracle.version>11.2.0.1.0</oracle.version>
        <mybatis.version>3.4.5</mybatis.version>
        <spring.security.version>5.0.1.RELEASE</spring.security.version>
    </properties>

    </build>

三、开始 ssm整合配置文件的编写

编写实体类（domain），编写业务接口（service），编写持久层接口（dao）

spring环境搭建（applicationContext） 编写业务层实现类（使用注解Service）

  • ==========applicationContext============
<!-- 开启注解扫描，管理service和dao -->
<context:component-scan base-package="com.cnblogs.ssm.service">
</context:component-scan>
<context:component-scan base-package="com.cnblogs.ssm.dao">
</context:component-scan>

springmvc环境搭建以及，spring和mvc的整合

  • ========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"
	version="3.1">

	<!-- 配置加载类路径的配置文件 -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath*:applicationContext.xml,classpath*:spring-security.xml</param-value>
	</context-param>

<!-- 配置监听器 -->
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
	<!-- 配置监听器，监听request域对象的创建和销毁的 -->
	<listener>
		<listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>
	</listener>

	


	<!-- 前端控制器（加载classpath:springmvc.xml 服务器启动创建servlet） -->
	<servlet>
		<servlet-name>dispatcherServlet</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<!-- 配置初始化参数，创建完DispatcherServlet对象，加载springmvc.xml配置文件 -->
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath:springmvc.xml</param-value>
		</init-param>
		<!-- 服务器启动的时候，让DispatcherServlet对象创建 -->
		<load-on-startup>1</load-on-startup>
	</servlet>
	<servlet-mapping>
		<servlet-name>dispatcherServlet</servlet-name>
		<url-pattern>*.do</url-pattern>
	</servlet-mapping>

	<!-- 解决中文乱码过滤器 -->
	<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>
	</filter>
	<filter-mapping>
		<filter-name>characterEncodingFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

	<!-- 委派过滤器 -->
	<filter>
		<filter-name>springSecurityFilterChain</filter-name>
		<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
	</filter>
	<filter-mapping>
		<filter-name>springSecurityFilterChain</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

	<welcome-file-list>
		<welcome-file>index.html</welcome-file>
		<welcome-file>index.htm</welcome-file>
		<welcome-file>index.jsp</welcome-file>
		<welcome-file>default.html</welcome-file>
		<welcome-file>default.htm</welcome-file>
		<welcome-file>default.jsp</welcome-file>
	</welcome-file-list>
</web-app>
  • =========spring-mvc.xml=========

<?xml version="1.0" encoding="UTF-8"?>

           ">

	<!-- 扫描controller的注解，别的不扫描 -->
	<context:component-scan base-package="com.cnblog.ssm.controller">		
	</context:component-scan>

	<!-- 配置视图解析器 -->
	<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<!-- JSP文件所在的目录 -->
		<property name="prefix" value="/pages/" />
		<!-- 文件的后缀名 -->
		<property name="suffix" value=".jsp" />
	</bean>

	<!-- 设置静态资源不过滤 -->
	<mvc:resources location="/css/" mapping="/css/**" />
	<mvc:resources location="/img/" mapping="/img/**" />
	<mvc:resources location="/js/" mapping="/js/**" />
	<mvc:resources location="/plugins/" mapping="/plugins/**" />

	<!-- 开启对SpringMVC注解的支持 -->
	<mvc:annotation-driven />

	<!-- 
		支持AOP的注解支持，AOP底层使用代理技术
		JDK动态代理，要求必须有接口
		cglib代理，生成子类对象，proxy-target-class="true" 默认使用cglib的方式
	-->
	<aop:aspectj-autoproxy proxy-target-class="true"/>
	
</beans>

spring和 mybatis的整合（主要是配置数据源和sqlsessionFactory）

  • =========applicationContext=============
<context:property-placeholder location="classpath:db.properties"/>
	<!-- 配置连接池 -->
	<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
   		<property name="driverClass" value="${jdbc.driver}" />
   		<property name="jdbcUrl" value="${jdbc.url}" />
   		<property name="user" value="${jdbc.username}" />
   		<property name="password" value="${jdbc.password}" />
   	</bean>	
	<!-- 交给IOC管理 SqlSessionFactory -->
	<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
   		<property name="dataSource" ref="dataSource" />
   	</bean>
	
	<!-- 扫描dao接口 -->
	<bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
   		<property name="basePackage" value="com.cnblog.ssm.dao"/>
   	</bean>
	
	<!-- 配置Spring的声明式事务管理 -->
	<!-- 配置事务管理器 -->
   	<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
   		<property name="dataSource" ref="dataSource"/>
   	</bean>

  <tx:annotation-driven transaction-manager="transactionManager"/>
