1、spring与mybatis整合的配置文件为springmvc-dao.xml，内容如下

  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <beans xmlns="http://www.springframework.org/schema/beans"
  3.        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  4.        xmlns:context="http://www.springframework.org/schema/context"
  5.        xmlns:mvc="http://www.springframework.org/schema/mvc"
  6.        xsi:schemaLocation="http://www.springframework.org/schema/beans

  10.         http://www.springframework.org/schema/mvc
  11.         http://www.springframework.org/schema/mvc/spring-mvc.xsd">
  13.     <!--注解扫描包路径-->
  14.     <context:component-scan base-package="com.test.dao"/>
  15.     <!--开启注解配置-->
  16.     <context:annotation-config/>
  17.     <!--关联数据库文件-->
  18.     <context:property-placeholder location="classpath:dbconfig.properties"/>
  20.     <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">

  22.         <property name="url" value="${jdbcUrl}"/>
  23.         <property name="username" value="${username}"/>
  24.         <property name="password" value="${password}"/>
  25.         <!--c3p0连接池的私有属性-->

  35.         <property name="configLocation" value="classpath:mybatisConfig.xml"/>
  36.     </bean>
  38.     <!-- 4.配置扫描Dao接口包，动态实现Dao接口注入到spring容器中 -->
  39.     <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
  40.         <!-- 注入sqlSessionFactory -->
  41.         <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
  42.         <!-- 给出需要扫描Dao接口包 -->
  43.         <property name="basePackage" value="com.test.dao"/>
  44.     </bean>
  45. </beans>

2、spring与service整合的配置文件:springmvc-service.xml

  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <beans xmlns="http://www.springframework.org/schema/beans"
  3.        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  4.        xmlns:context="http://www.springframework.org/schema/context"
  5.        xsi:schemaLocation="http://www.springframework.org/schema/beans
  6.     http://www.springframework.org/schema/beans/spring-beans.xsd
  7.     http://www.springframework.org/schema/context
  8.     http://www.springframework.org/schema/context/spring-context.xsd">
  10.     <!-- 扫描service相关的bean -->
  11.     <context:component-scan base-package="com.test.service" />
  13.     <!--<!– 配置事务管理器 –>-->
  14.     <!--<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">-->

  16.         <!--<property name="dataSource" ref="dataSource" />-->
  17.     <!--</bean>-->
  19. </beans>

3、spring与controller整合的配置文件springmvc-servlet.xml

备注：

注意事项1：添加如下信息时，执行报如下500的错，将如下信息注释掉，访问正常，故先注释掉

注意事项2： 前缀WEB-INF/jsp/ 前一定要加 “/” ，，否则会报找不到文件404

  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <beans xmlns="http://www.springframework.org/schema/beans"

  13.     <!--注解扫描包路径-->
  14.     <context:component-scan base-package="com.jin.controller"/>
  15.     <!--使用注解驱动，配置请求控制器和适配器-->
  16.     <mvc:annotation-driven>
  17.         <!--<mvc:message-converters register-defaults="true">-->
  18.             <!--<bean class="org.springframework.http.converter.StringHttpMessageConverter">-->
  19.                 <!--<constructor-arg value="UTF-8"/>-->
  20.             <!--</bean>-->
  21.             <!--<bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">-->
  22.                 <!--<property name="objectMapper">-->
  23.                     <!--<bean class="org.springframework.http.converter.json.Jackson2ObjectMapperFactoryBean">-->
  24.                         <!--<property name="failOnEmptyBeans" value="false"/>-->

  29.     </mvc:annotation-driven>
  30.     <!--配置静态处理 css-->
  31.     <mvc:default-servlet-handler/>
  32.     <!--配置视图解析器-->
  33.     <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
  34.         <!--前缀-->
  35.         <property name="prefix" value="/WEB-INF/jsp/" />
  36.         <!--后缀-->
  37.         <property name="suffix" value=".jsp" />
  38.     </bean>
