• 第十讲:springmvc+spring+mybatis+jquery整合


    springmvc+spring+mybatis整合(听起来高大上,实际就是把配置文件弄一块来了)

    1、导入相关jar包

    2、编写配置文件

      a总、web.xml----配置spring    配置springmvc

     <!-- spring  配置文件 -->
      <context-param>
          <param-name>contextConfigLocation</param-name>
          <param-value>classpath:applicationContext.xml</param-value>
      </context-param>
      <listener>
          <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
      </listener>
      <!-- springmvc 配置文件 -->
      <servlet>
          <servlet-name>springmvc</servlet-name>
          <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
          <init-param>
              <param-name>contextConfigLocation</param-name>
              <param-value>classpath:mvc.xml</param-value>
          </init-param>
          <load-on-startup>1</load-on-startup>
      </servlet>
      <servlet-mapping>
          <servlet-name>springmvc</servlet-name>
          <url-pattern>*.do</url-pattern>
      </servlet-mapping>

      b、mvc.xml----springmvc的配置文件---最简单的配置使用注解扫描,如果需要json或其他处理填写相关配置

    <?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:p="http://www.springframework.org/schema/p"
        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/context
            http://www.springframework.org/schema/context/spring-context.xsd">
        
        <!-- 注解扫描,自动扫描这个包下面的注解 -->
        <context:component-scan base-package="cn.sxt.controller"></context:component-scan>
        
    </beans>

      c、applicationcontext.xml---spring的配置文件

    <?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: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">
    <!--一、 配置datasource连接池    这种配置肯定是为了读取一个properties文件(下面ab两种方式,b有的时候不行))-->
        <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
            <property name="driverClassName" value="${driver}"></property>
            <property name="url" value="${url}"></property>
            <property name="username" value="${username}"></property>
            <property name="password" value="${password}"></property>
        </bean>
        <!-- a 这个就是为了读取这个配置文件的-->
        <bean class="org.springframework.beans.factory.config.PlaceholderConfigurerSupport">
            <property name="localion" value="classpath:db.properties"></property>
        </bean>        <!-- b <context:property-placeholder location="db.properties"/>-->
    <!--二、配置工厂 -->
        <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
            <property name="dataSorce" ref="dataSource"></property>
         <property name="configLocation" value="classpath:mybatis.cfg.xml"/>//新加的 </bean> <!--三、配置声明式事务 --><!--a 配置事务管理器 --> <bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource"></property> </bean> <tx:advice id="txAdvice" transaction-manager="txManager"> <tx:attributes> <tx:method name="save" propagation="REQUIRED"/> <tx:method name="get" read-only="true"/> <tx:method name="*" propagation="REQUIRED"/> </tx:attributes> </tx:advice> <aop:config> <aop:pointcut expression="execution(*cn.sxt.service.impl.*.*(..))" id="pointcut"/> <aop:advisor advice-ref="txAdvice" pointcut-ref="pointcut"/> </aop:config> <!--四、配置注解扫描 一行搞定自结束 --> <context:component-scan base-package="cn.sxt"/> </beans>

    上面截图后来修改在配置工厂属性里面新增了对mybatis的配置,见代码改变部分

      d、mybatis---mybatis的配置文件(可有可无,看你怎么整合)

    在mybatis3的pdf中拷贝过来的图片,不代表真实配置

    真实配置图片及代码

    <?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>
        <typeAliases>
            <package name="cn.sxt.vo"/>
        </typeAliases>
        <mappers>
            <!-- 添加所有的mapper文件填写位置-->
        </mappers>
    </configuration>

     3、编码
