SSM框架之整合

1.首先创建数据库

2.创建项目

3.导入所需要的坐标

4.进行mybatis的配置（使用注解方式），并编写SqlMapConfig.xml,内容如下（Dao层配置），并测试

<?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">
  <!--mybatis主配置文件-->
<configuration>
    <!--配置properties-->
    <properties resource="jdbcConfig.properties">
        <!--<property name="driver" value="com.mysql.jdbc.Driver"/>
        <property name="url" value="jdbc:mysql://localhost:3306/user"/>
        <property name="username" value="root"/>
        <property name="password" value="wzp961208"/>-->

    </properties>
    <!--使用typeAliases配置别名-->
    <typeAliases>
        <typeAlias type="com.ping.domain.Users" alias="user"></typeAlias>
       <!-- 用于指定要配置别名的包.类名就是别名,不区分大小写-->
        <package name="com.ping.domain"></package>
    </typeAliases>
    <!--配置环境-->
    <environments default="mysql">
       <!-- 配置mysql环境-->
        <environment id="mysql">
            <!--配置事务类型-->
            <transactionManager type="JDBC"></transactionManager>
           <!-- 配置连接池-->
            <dataSource type="POOLED">
                <!--配置连接数据库基本信息-->
                <property name="driver" value="${jdbc.driver}"/>
                <property name="url" value="${jdbc.url}"/>
                <property name="username" value="${jdbc.username}"/>
                <property name="password" value="${jdbc.password}"/>
            </dataSource>
        </environment>
    </environments>
   <!-- 映射配置文件，每个独立dao的配置文件-->
    <mappers>
       <!-- <mapper resource="com/ping/Dao/IUsersDao.xml"></mapper>-->
        <package name="com.ping.Dao"></package>
    </mappers>
</configuration>

5.业务层配置（食用Spring配置）其中建立ApplicationContext.xml,内容如下

<?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.ping">
        <!--配置不需要扫描的注解-->
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>
 
</beans>

6. 表现层Spring MVC的配置，首先配置前端控制器（web.xml)以及视图解析器（Spring MVC.xml）

web.xml配置：

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>
  <display-name>Archetype Created Web Application</display-name>
  <servlet>
    <servlet-name>dispatcherServlet</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>
  <servlet-mapping>
    <servlet-name>dispatcherServlet</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>
  <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>
</web-app>

Spring MVC.xml配置：

<?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">
    <context:component-scan base-package="com.ping">
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>
    <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>
    <!-- 设置静态资源不过滤 -->
    <mvc:resources location="/css/" mapping="/css/**" />
    <mvc:resources location="/images/" mapping="/images/**" />
    <mvc:resources location="/js/" mapping="/js/**" />

    <mvc:annotation-driven></mvc:annotation-driven>

</beans>

7.其中先把spring与spring MVC整合，在web.xml中配置监听器即可

<!--  spring与spring MVC得整合-->
  <!--监听器，只加载WEB-INF下applicationContextx.xml文件-->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <!--配置路径-->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
  </context-param>

8.再把spring与Mybatis,即在applicationContext.xml配置mybatis 

内容如下：

<!--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>
        <property name="jdbcUrl" value="jdbc:mysql:///ssm"></property>
        <property name="user" value="root"></property>
        <property name="password" value="wzp961208"></property>
    </bean>
    <!--配置SqlSessionFactoty-->
    <bean id="sessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"></property>
    </bean>
    <!--配置接口所在的包-->
    <bean id="mapperScannerConfigurer" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.ping.Dao"></property>
    </bean>
    <!--配置spring 声明式事务管理-->
    <bean id ="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"></property>
    </bean>
    <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>
    <aop:config >
        <aop:advisor advice-ref="txadvice" pointcut="execution(* com.ping.Service.Impl.AccountServiceImp.*(..))"></aop:advisor>
    </aop:config>

9.删除SqlMapConfig.xml即可
