2.搭建整合环境
1. 整合说明：SSM整合可以使用多种方式，咱们会选择XML + 注解的方式
1> 整合的思路
1. 先搭建整合的环境
2. 先把Spring的配置搭建完成
3. 再使用Spring整合SpringMVC框架
4. 最后使用Spring整合MyBatis框架
2>创建maven的工程（今天会使用到工程的聚合和拆分的概念，这个技术maven高级会讲）
1. 创建ssm_parent父工程（打包方式选择pom，必须的）
2. 创建ssm_web子模块（打包方式是war包）
3. 创建ssm_service子模块（打包方式是jar包）
4. 创建ssm_dao子模块（打包方式是jar包）
5. 创建ssm_domain子模块（打包方式是jar包）
6. web依赖于service，service依赖于dao，dao依赖于domain
7. 在ssm_parent的pom.xml文件中引入坐标依赖
3>创建测试文件
3.搭建web.xml
<!--配置Spring的监听器，默认只加载WEB-INF目录下的applicationContext.xml配置文件 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!--设置配置文件的路径 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param> <!--前端控制器 -->
<servlet>
<servlet-name>springDispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!--初始化时 加载sringmvx.xml -->
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:SpringMVC.xml</param-value>
</init-param>
<!--启动服务器时，创建Servlet -->
<load-on-startup>1</load-on-startup>
</servlet> <servlet-mapping>
<servlet-name>springDispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping> <!-- 配置 springMVC 编码过滤器 -->
<filter>
<filter-name>CharacterEncodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<!-- 设置过滤器中的属性值 -->
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
<!-- 启动过滤器 -->
<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>
4.搭建Spring的开发环境(使用注解开发)
将sqlMapconfig.xml 整合到applicationContext.xml中去 sqlMapconfig使用注解开发
applicationContext.context
<?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:aop="http://www.springframework.org/schema/aop"
xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd"> <!--开启注解扫描 -->
<!--希望只扫描service和dao，controller不需要Spring框架去处理 -->
<context:component-scan base-package="com.hdh">
<!--配置哪些注解不扫描 -->
<context:exclude-filter type="annotation"
expression="org.springframework.stereotype.Controller" />
</context:component-scan> <!--Spring整合MyBatis -->
<!--配置连接池 -->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="driverClass" value="com.mysql.jdbc.Driver" />
<property name="jdbcUrl" value="jdbc:mysql:///ssm" />
<property name="user" value="root" />
<property name="password" value="12345" />
</bean> <!--配置SqlsessionFactory -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"></property>
</bean> <!-- 配置AccountDao接口所在的包 -->
<bean id="mapperScannerConfigurer" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.hdh.dao"></property>
</bean> <!--配置Spring的事物管理 -->
<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"></property>
</bean> <!--配置事物通知 -->
<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="find" read-only="true" />
</tx:attributes>
</tx:advice> <!--配置AOP增强 -->
<aop:config>
<aop:advisor advice-ref="txAdvice" pointcut="execution(* com.hdh.service.impl.*.*(..))" />
</aop:config> </beans>
5 搭建Spring的开发环境（使用xml开发）
并且将sqlMapconfig.xml 整合到applicationContext.xml中去 sqlMapconfig使用xml开发
applicationContext.context
<?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:aop="http://www.springframework.org/schema/aop"
xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx.xsd"> <context:component-scan base-package="com.hdh">
<!--配置哪些注解不扫描 -->
<context:exclude-filter type="annotation"
expression="org.springframework.stereotype.Controller" />
</context:component-scan> <!--配置连接池 -->
<!-- <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="url" value="jdbc:mysql://localhost:3306/ssm" />
<property name="username" value="root" />
<property name="password" value="12345" />
</bean> -->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="driverClass" value="com.mysql.jdbc.Driver" />
<property name="jdbcUrl" value="jdbc:mysql://localhost:3306/ssm" />
<property name="user" value="root" />
<property name="password" value="12345" />
</bean> <!--配置SqlSessionFactory工厂-->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
</bean> <!--配置AccountDao接口所在包-->
<bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.hdh.dao"/>
</bean> <!--配置Spring框架声明式事务管理-->
<!--配置事务管理器-->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean> <!--配置事务通知-->
<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="find*" read-only="true"/>
<tx:method name="*" isolation="DEFAULT"/>
</tx:attributes>
</tx:advice> <!--配置AOP增强-->
<aop:config>
<aop:advisor advice-ref="txAdvice" pointcut="execution(* com.hdh.service.impl.*ServiceImpl.*(..))"/>
</aop:config> </beans>
6.SpringMVC的整合
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd">
<!--开启注解扫描 扫描Controller -->
<context:component-scan base-package="com.hdh" >
<context:include-filter type="annotation"
expression="org.springframework.stereotype.Controller" />
</context:component-scan> <!--配置视图解析去 -->
<bean id="internalResourceViewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/pages/"></property>
<property name="suffix" value=".jsp"></property>
</bean> <!--配置过滤静态资源 -->
<mvc:resources location="/css/" mapping="/css/**"></mvc:resources>
<mvc:resources location="/images/" mapping="/images/**"></mvc:resources>
<mvc:resources location="/js/" mapping="/js/**"></mvc:resources> <!--开启SpringMVC注解的支持 -->
<mvc:annotation-driven></mvc:annotation-driven>
<!--配置拦截器-->
<mvc:interceptors>
<mvc:interceptor>
<mvc:mapping path="/**" />
<mvc:exclude-mapping path="/user/login"></mvc:exclude-mapping>
<bean class="com.hdh.web.interceptor.Myinterceptior"></bean>
</mvc:interceptor>
</mvc:interceptors>
<!--配置json-->
<bean id="jsonConverter" class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
<property name="supportedMediaTypes">
<list>
<value>application/json;charset=UTF-8</value>
</list>
</property>
</bean>
</beans>
7.整合要点
1>web.xml中要配置监听器用于在服务器开启时自动加载applicationContext.xml 并且指定applicationContext.xml文件的位置
<!--配置Spring的监听器，默认只加载WEB-INF目录下的applicationContext.xml配置文件 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!--设置配置文件的路径 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
2>.Spring对jackson的整合
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-core</artifactId>
<version>2.9.5</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.9.5</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-annotations</artifactId>
<version>2.9.5</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.module</groupId>
<artifactId>jackson-module-jaxb-annotations</artifactId>
<version>2.9.5</version>
</dependency>
在springmvc中配置jakcson
<!--配置json-->
<bean id="jsonConverter" class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
<property name="supportedMediaTypes">
<list>
<value>application/json;charset=UTF-8</value>
</list>
</property>
</bean>
