Spring整合Mybatis关于Dao注入失败的问题求解
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'adminService': Injection of autowired nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private pers.zww.grad.dao.IAdminDao pers.zww.grad.service.impl.AdminServiceImpl.adminD nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [pers.zww.grad.dao.IAdminDao] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true), @org.springframework.beans.factory.annotation.Qualifier(value=adminDao)}
此为自动生成的Mapper，我加了注解@Repository
package pers.zww.grad.
import org.springframework.stereotype.R
import pers.zww.grad.vo.A
@Repository("adminDao")
public interface IAdminDao {
int deleteByPrimaryKey(String id);
int insert(Admin record);
int insertSelective(Admin record);
Admin selectByPrimaryKey(String id);
int updateByPrimaryKeySelective(Admin record);
int updateByPrimaryKey(Admin record);
Integer getCountByName(String name);
Integer getCountByNameAndPass(String name,String password);
这是Service里面注入
package pers.zww.grad.service.
@Service("adminService")
public class AdminServiceImpl implements IAdminService {
@Autowired
@Qualifier("adminDao")
private IAdminDao adminD
public int deleteByPrimaryKey(String id) {
// TODO Auto-generated method stub
配置文件都已扫描过了，而且相关mybatis的如下：
&bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"&
&property name="dataSource" ref="dataSource" /&
&!-- 自动扫描mapping.xml文件 --&
&property name="mapperLocations" value="classpath:pers/zww/grad/mapping/*.xml"&&/property&
&!-- 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="pers.zww.grad.dao" /&
&property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"&&/property&
按赞数排序
自动扫描的包有没有加进去
&!-- 对web包中的所有类进行扫描，以完成Bean创建和自动依赖注入的功能 --&
问题已解决，谢谢大家。
大哥你这个问题解决了么，我遇到了，求教
&bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"&
&property name="dataSource" ref="dataSource" /&
&property name="typeAliasesPackage"&
pers.zww.grad.vo
&/property&
&!-- 自动扫描mapping.xml文件 --&
&property name="mapperLocations" value="classpath:pers/zww/grad/mapping/*.xml"&&/property&
你的注解加到实现类中，不要加接口类
@Repository("adminDao")为什么注解在接口上呢
&context:component-scan base-package="pers.zww.grad.*"&
只写pers.zww.grad试下，我自己的工程加上.*后就报找不到bean了，可能是不支持这样写。
另外@Autowired默认按照类型注入，可以不指定bean的名称。
估计是包扫描的问题吧，，
我也想知道,我的也是不能注入呢,不是不需要实现么

京ICP备号-1 京公网安备02号我自己搭了一个struts2+Mybatis+Spring的框架，想通过MapperScannerConfigurer来自动添加Mybatis的mapper，发现一个很奇怪的问题：
如果不使用MapperScannerConfigurer，而采取手动配置添加mapper，一切正常；
如果使用了MapperScannerConfigurer，服务器启动的时候会报错，但是报的是数据源配置读取错误，好像和MapperScannerConfigurer无关。
错误信息和spring配置文件如下：

谢谢！我的配置文件在1楼贴出来了，我左看右看都没什么问题啊，而且只要将MapperScannerConfigurer所在的bean配置删除或者注释掉，就可以正常工作。MapperScannerConfigurer的bean连名字都没有，应该不会有冲突吧？
这里面没有我自己写的set方法，因为被注入的对象都是系统或者框架提供的类，框架应该不会有问题的吧。
最后请教如何看报错日志
Caused&by:&java.lang.NumberFormatException:&For&input&string:&&${jdbc.maxPoolSize}&
property中的定义是否后面多了空格。
没有，不用扫描方式添加mapper都好好的正常工作
${jdbc.maxPoolSize}这个肯定没有问题,
原因是你加入了MapperScannerConfigurer
他会优先于PropertyPlaceholderConfigurer执行,所以这个时候,${jdbc.maxPoolSize}还没有被解析呢,
故没有被mysql.properties里面的值所替换,所以出现NumberFormatException就是情理之中了
这是mybatis-spring的一个己经公开的问题
详细解决办法请看

谢谢啊，我已经按照解决方法修改了配置文件，启动不再报错，但始终搜索不到包下面的mapper，没有报错，只有提示：“No&MyBatis&mapper&was&found&in&'config.mybatis'&package.&Please&check&your&configuration.”
但是这个包下面肯定是有xml的mapper文件的啊！

由于无法自动加载mapper，我跟踪到mybatis和spring源代码里面发现其对于mapper的搜索是基于ClassPathScanningCandidateComponentProvider类的findCandidateComponents方法，但是用来匹配的resourcePattern默认值却是&**/*.class&，无法匹配mapper的xml文件，这是怎么回事？难道要我把xml修改成class？
用sqlSessionTemplate就不能用&自动扫描，&用自动扫描&就要用mybatis的接口

你这个问题解决没？我去官网上也没看到解决方案！我的也是用自动扫描就报错不能正常解析properties内容。
