shiro配置报错问题

开始在配置shiro一直报错

下面直接上代码，我开始的配置是这样的：

<!-- 配置权限管理器 -->      <bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager"   >            <!-- 使用下面配置的缓存管理器 -->          <property name="cacheManager" ref="cacheManager"/>           <property name="sessionMode" value="native"/>        <!-- ref对应我们写的realm  MyShiro -->          <property name="realm" ref="myShiro"/>            <property name="sessionManager" ref="sessionManager"/>    </bean>  

下面是报的错位置：

org.springframework.beans.factory.BeanCreationException:

 Error creating bean with name 'shiroFilter' defined in class path resource [applicationContext-shiro.xml]: 

BeanPostProcessor before instantiation of bean failed; 

nested exception is org.springframework.beans.factory.BeanCreationException: 

Error creating bean with name 'org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor#0' 

defined in class path resource [applicationContext-shiro.xml]:

 nested exception is org.springframework.beans.factory.BeanCreationException:

nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'myShiro': 

Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException:

MyShiro.userService; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException:

 No qualifying bean of type [com.kj.service.UserService] 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=userService)}

接着下面的错误：

Caused by: org.springframework.beans.factory.BeanCreationException: 

Error creating bean with name 'securityManager' defined in class path resource [applicationContext-shiro.xml]: 

Cannot resolve reference to bean 'myShiro' while setting bean property 'realm';

 nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'myShiro':

 nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException:

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=userService)}

1.接着分析：

配置的包名检查过了没有什么问题。

2.接着分析：

是不是不能自动注入？

接着检查我的注解也都没有什么问题：

dao的注解：

import com.kj.domain.Permission;/* * Permission对应的Dao接口类 */@Repository("permissionMapper")public interface PermissionMapper {

service的注解：

@Service("userService")public class UserServiceImpl implements UserService{@Autowired@Qualifier("userMapper")private UserMapper userMapper;

filter的 注解：

@Service@Transactionalpublic class MyShiro extends AuthorizingRealm {    @Autowired    @Qualifier("userService")    private UserService userService;

最后！

在网上找资料才解决。

<!-- 配置权限管理器 -->      <bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager"    depends-on="permissionMapper,roleMapper,rolePermissionMapper,userMapper,userRoleMapper">            <!-- 使用下面配置的缓存管理器 -->          <property name="cacheManager" ref="cacheManager"/>           <property name="sessionMode" value="native"/>        <!-- ref对应我们写的realm  MyShiro -->          <property name="realm" ref="myShiro"/>            <property name="sessionManager" ref="sessionManager"/>    </bean>  

就是在自定义realm中，一定要用depends-on加入所有的userService依赖持久层里面的dao。
