spring+springmvc+mybatis扫描mapper文件的问题

如下数据源的配置文件中mybatis的mapper扫描代码

...省略数据源配置

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="configLocation" value="classpath:mybatis.xml" />
    <property name="dataSource" ref="dataSource" />
    <property name="mapperLocations" value="classpath*:mapper/*.xml" />
</bean>

<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
    <property name="basePackage" value="xxx.dao" />
    <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
</bean>
      ... 

####将这段代码放在spring 的配置文件中就扫描不到吗mybatis的mapper但是
####放在spring-mvc的配置文件中就可以扫描到是应为什么原因呢?
####求大神告知

2个回答

是不因为 你的pom文件 值引用了 spring-mvc 的配置

因为你的数据源dataSource 是配置在mvc的xml中的

springMVC+myBatis中如何进行事务处理

springMVC+myBatis中在使用注解方式的时候如何进行事务处理

求,SpringMVC+MyBatis免xml的纯java注解配置方式?

不想做伸手党,这次实在没办法; 新项目需要用到mybatis,之前公司一直用springMvc+hibernate, 都是用一个WebApplicationInitializer实现类+WebMvcConfiguration实现类 用纯注解方式配置。 然而自己只会用xml配置mybatis,找得到注解写mybatis的sql语句, 但实在找不到SpringMVC+MyBatis的配置注解,百度的净是些挂羊头卖狗肉的 xml配置, 只能求助于各位道友了?

在spring中使用mybatis.其中目录结构如下 ![图片说明](https://img-ask.csdn.net/upload/201512/13/1449936546_649645.png) spring配置文件如下: ``` <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource"/> <property name="configLocation" value="classpath:mybatis.xml"/> </bean> <!-- dao接口的扫描--> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="xblog.dal.dao"/> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/> </bean> ``` 其中mybatis配置文件mybatis.xml在resources文件夹中,内容如下: ``` <mappers> <mapper resource="xblog/dal/mybatis/UserMapper.xml" /> <mappers> ``` UserMapper.xml放在java源码的xblog.dal.mybatis这个package下, 测试时,出错: Caused by: java.io.IOException: Could not find resource xblog/dal/mybatis/UserMapper.xml 把UserMapper.xml放在resources目录下,并将mybatis.xml修改为: <mapper resource="UserMapper.xml" /> 就可以通过测试.请问: 如何访问到package目录下的资源.

spring mvc整合mybatis 为什么不把mapper接口类直接注入Controller呢

# spring mvc整合mybatis 为什么不把mapper接口类直接注入Controller呢? 正常开发如下: 1、mapper.xml,mapper接口类,service接口,serviceImpl实现类,Controller控制类 2、serviceImpl实现类注入mapper接口类,在Controller控制类中注入service接口 ## 问题1、为什么不直接把mapper接口类注入到Controller控制类中应用呢? ## 问题2:或者设计一个公用执行方法类,该类实现applicationContextAware接口,然后直接在spring容器中获取已经实例化的mapper接口,通过反射原理执行该接口的某个指定方法。最后在controller类中的方法里直接调用该类执行由前端传进来的方法名 请问各位大神这两种情况有什么影响呢?

SPRING+MYBATIS DAO不写实现类的优缺点

现在流行MYBATIS不写DAO实现类,请问这样做的优缺点是什么啊

关于springMVC与Mybatis整合时对sqlSessionFactory和init的问题

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sqlSessionFactory' defined in class path resource [spring/applicationContext.xml]: Invocation of init method failed; nested exception is org.springframework.core.NestedIOException: Failed to parse mapping resource: 'file [D:\workplace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\SpringMVC-mybatis\WEB-INF\classes\com\crud\mapper\UserMapper.xml]'; nested exception is org.apache.ibatis.builder.BuilderException: Error parsing Mapper XML. Cause: org.apache.ibatis.builder.BuilderException: Error resolving class. Cause: org.apache.ibatis.type.TypeException: Could not resolve type alias 'userResultMap'. Cause: java.lang.ClassNotFoundException: Cannot find class: userResultMap

Springmvc-myBatis配置文件不解析数据库的properties文件

初次配置SpringMVC+myBatis,使用properties来存储数据库的相关数据,并在xml中读取出来,写入dataSource中。 这时发现报错:Cannot load JDBC driver class ${jdbc.driverClassName} java.lang.ClassNotFoundException: ${driverClass} 按理说没有jar包,应该报错Cannot load JDBC driver class com.mysql.jdbc.Drive ``` <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> <property name="driverClassName" value="${driverClass}"/> <property name="url" value="${jdbcUrl}"/> <property name="username" value="${username}"/> <property name="password" value="${password}"/> ``` 如果像上述这样就会报错,properties文件无误。 如果改成这样: ``` <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> <property name="driverClassName" value="com.mysql.jdbc.Driver"/> <property name="url" value="jdbc:mysql://localhost:3306/Lettiy"/> <property name="username" value="root"/> <property name="password" value="root"/> ``` 便可以正常访问,所以怀疑时properties文件没有正常导入 在xml最开始已经引入了该properties,路径正确,可以通过ctrl直接打开 ``` <context:property-placeholder location="classpath:jdbc.properties"/> ``` 现在贴出全部的xml ``` <?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:property-placeholder location="classpath:jdbc.properties"/> <!-- 扫描注解Bean --> <context:component-scan base-package="*.service"> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan> <!-- 开启AOP监听 只对当前配置文件有效 --> <aop:aspectj-autoproxy expose-proxy="true"/> <!--myBatis 配置--> <!-- 第一种方式:加载一个properties文件 --> <!--<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">--> <!--<property name="location" value="classpath:resource/jdbc.properties"/>--> <!--</bean>--> <!-- 配置数据源 --> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> <property name="driverClassName" value="${driverClass}"/> <property name="url" value="${jdbcUrl}"/> <property name="username" value="${username}"/> <property name="password" value="${password}"/> </bean> <!-- mybatis和spring完美整合,不需要mybatis的配置映射文件 --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="configLocation" value="classpath:mybatis-spring.xml" /> <property name="dataSource" ref="dataSource"/> <!-- 自动扫描mapping.xml文件 --> <property name="mapperLocations" value="classpath:datamapper/**/*.xml"></property> </bean> <!-- DAO接口所在包名,Spring会自动查找其下的类 --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="login.repository"/> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property> </bean> <!-- (事务管理)transaction manager, use JtaTransactionManager for global tx --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource"/> </bean> <!-- (事务管理)transaction manager, use JtaTransactionManager for global tx --> <tx:annotation-driven transaction-manager="transactionManager"/> <!--repository 注解扫描--> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="annotationClass" value="org.springframework.stereotype.Repository"/> <property name="basePackage" value="login.repository"/> <property name="sqlSessionFactory" ref="sqlSessionFactory"/> </bean> </beans> ```
