  • 整合springmvc+mybatis+spring

    7382c180c65140c58f00f598d58cb856

    1)编写 sqlMapConfg.xml 核心配置文件 (指定扫描包,会把包内所有的类都设置别名 )

    <?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>
        <!-- 设置别名 -->
        <typeAliases>
            <!-- 2. 指定扫描包,会把包内所有的类都设置别名,别名的名称就是类名,大小写不敏感 -->
            <package name="com.itheima.springmvc.pojo" />
        </typeAliases>
    
    </configuration>

    2) 配置spring 核心配置文件 applicationContext.xml

    配置数据源 druid, 读取db.properties, mybatis的工厂,mybatis的动态

    代理开发扫描方式 事务

     <?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
        xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"
        xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
        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-4.0.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
        http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd
        http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd">
    
    
        <context:property-placeholder location="classpath:db.properties"/>
        
        <!-- 数据库连接池 -->
        <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}" />
            <property name="maxActive" value="10" />
            <property name="maxIdle" value="5" />
        </bean>
        
        <!-- Mybatis的工厂 -->
        <bean id="sqlSessionFactoryBean" class="org.mybatis.spring.SqlSessionFactoryBean">
            <property name="dataSource" ref="dataSource"/>
            <!-- 核心配置文件的位置 -->
            <property name="configLocation" value="classpath:sqlMapConfig.xml"/>
        </bean>
    
        <!-- Mapper动态代理开发   扫描包     ==》 如果不配置这个的话,就要将所有的mapper注册到spring中 -->
        <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
            <!-- 基本包 -->
            <property name="basePackage" value="com.itheima.springmvc.dao"/>
        </bean>
        
        <!-- 注解事务 -->
        <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
            <property name="dataSource" ref="dataSource"/>
        </bean>
        
        <!-- 开启注解 -->
        <tx:annotation-driven transaction-manager="transactionManager"/>
    </beans>

    3)创建db.properties

    jdbc.driver=com.mysql.jdbc.Driver
    jdbc.url=jdbc:mysql://localhost:3306/springmvc?characterEncoding=utf-8
    jdbc.username=root
    jdbc.password=houchen

    配置springMvc的三大组件和自定义转换器

    <?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-4.0.xsd
            http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
            http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd">
    
            
            
            <!-- 扫描@Controler  @Service   -->
            <context:component-scan base-package="com.itheima"/>
            
            <!-- 处理器映射器 -->
    <!--         <bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping"/> -->
            <!-- 处理器适配器 -->
    <!--         <bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter"/> -->
            <!-- 注解驱动 -->
            <mvc:annotation-driven conversion-service="conversionServiceFactoryBean"/>
            
            <!-- 配置Conveter转换器  转换工厂 (日期、去掉前后空格)。。 -->
            <bean id="conversionServiceFactoryBean" class="org.springframework.format.support.FormattingConversionServiceFactoryBean">
                <!-- 配置 多个转换器-->
                <property name="converters">
                    <list>
                        <bean class="com.itheima.springmvc.conversion.DateConveter"/>
                    </list>
                </property>
            </bean>
            
            <!-- 视图解释器 -->
            <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
                <property name="prefix" value="/WEB-INF/jsp/"/>
                <property name="suffix" value=".jsp"/>
            </bean>
            
       </beans>

    5) 创建web.xml文件,配置监听器读取 applicationContext.xml,

    配置前端控制器读取springmvc.xml

    配置post提交乱码处理filter

    <?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
      <display-name>springmvc-mybatis</display-name>

        <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>
      
      <context-param>
          <param-name>contextConfigLocation</param-name>
          <param-value>classpath:applicationContext.xml</param-value>
      </context-param>
      
      <!-- spring的监听器 -->
      <listener>
          <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
      </listener>
        
      <!-- 处理POST提交乱码问题 -->
      <filter>
          <filter-name>encoding</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>encoding</filter-name>
          <url-pattern>*.action</url-pattern>
      </filter-mapping>
      
        <!-- 前端控制器 -->
      <servlet>
          <servlet-name>springmvc</servlet-name>
          <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
          <!-- 默认找 /WEB-INF/[servlet的名称]-servlet.xml -->
          <init-param>
              <param-name>contextConfigLocation</param-name>
              <param-value>classpath:springmvc.xml</param-value>
          </init-param>
      </servlet>
      
      <servlet-mapping>
          <servlet-name>springmvc</servlet-name>
          <!-- 
              1. /*  拦截所有   jsp  js png .css  真的全拦截   建议不使用
              2. *.action *.do 拦截以do action 结尾的请求     肯定能使用   ERP  
              3. /  拦截所有 (不包括jsp) (包含.js .png.css)  强烈建议使用     前台 面向消费者  www.jd.com/search   /对静态资源放行
           -->
          <url-pattern>*.action</url-pattern>
      </servlet-mapping>
    </web-app>
