1、spring与mybatis整合的配置文件为springmvc-dao.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:mvc="http://www.springframework.org/schema/mvc"
           xsi:schemaLocation="http://www.springframework.org/schema/beans
            https://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/mvc
            http://www.springframework.org/schema/mvc/spring-mvc.xsd">
    
        
        <context:component-scan base-package="com.test.dao"/>
        
        <context:annotation-config/>
        
        <context:property-placeholder location="classpath:dbconfig.properties"/>
    
        <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
            <property name="driverClassName" value="${driverClass}"/>
            <property name="url" value="${jdbcUrl}"/>
            <property name="username" value="${username}"/>
            <property name="password" value="${password}"/>
            
            
            
        </bean>
    
        
        <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
            
            <property name="dataSource" ref="dataSource"/>
            
            <property name="configLocation" value="classpath:mybatisConfig.xml"/>
        </bean>
    
        
        <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
            
            <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
            
            <property name="basePackage" value="com.test.dao"/>
        </bean>
    </beans>

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

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 “/” ，<property name="prefix" value="**/**WEB-INF/jsp/" />，否则会报找不到文件404

<?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:mvc="http://www.springframework.org/schema/mvc"
           xsi:schemaLocation="http://www.springframework.org/schema/beans
            https://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/mvc
            http://www.springframework.org/schema/mvc/spring-mvc.xsd">
    
        
        <context:component-scan base-package="com.jin.controller"/>
        
        <mvc:annotation-driven>
            
                
                    
                
                
                    
                        
                            
                        
                    
                
            
        </mvc:annotation-driven>
        
        <mvc:default-servlet-handler/>
        
        <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
            
            <property name="prefix" value="/WEB-INF/jsp/" />
            
            <property name="suffix" value=".jsp" />
        </bean>
    
    </beans>

错误1：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xqajEyM18_size_16_color_FFFFFF_t_70][]

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