shiro框架,自定義realm注入service失敗解決辦法

報錯如下:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘shiroFilter’ defined in ServletContext resource [/WEB-INF/config/spring-shrio.xml]: Cannot resolve reference to bean ‘securityManager’ while setting bean property ‘securityManager’; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘securityManager’ defined in ServletContext resource [/WEB-INF/config/spring-shrio.xml]: Cannot resolve reference to bean ‘databaseRealm’ while setting bean property ‘realm’; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘databaseRealm’: Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.blog.service.ILoginService com.blog.realm.DatabaseRealm.loginSerivce; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.blog.service.ILoginService] 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)}

這么多大概就是一句話：自動注入失敗

問題分析: 查閱網絡上大量的問題分析,得到結論shiro 自定義realm的認證階段屬于filter，當時的spring bean還沒有讀取進來。

解決方案：換一種方式進行注入
寫一個工具類

@Component public class ApplicationContextUtils implements ApplicationContextAware {@Autowiredprivate static ApplicationContext context;@Overridepublic void setApplicationContext(ApplicationContext applicationContext) throws BeansException {this.context=applicationContext;}public static Object getBean(String name){return context.getBean(name);}}

需要使用的地方調用方法

@Overrideprotected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {System.out.println("-----------------------------");String principal = (String) token.getPrincipal();Object userServiceImpl = ApplicationContextUtils.getBean("userServiceImpl");System.out.println("aaaaaaaaaaaaaaa"+userServiceImpl);if("xiaochen".equals(principal)){return new SimpleAuthenticationInfo(principal,"123",this.getName());}return null;} }
