前几天把权限系统重构了,服务层针对前后台分别提供相应的接口,但在配置注入的时候出现如下错误:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sysCurrentSessionService' defined in ServletContext resource [/WEB-INF/servicecontext/sysUserContext.xml]: Initialization of bean failed; nested exception is org.springframework.beans.TypeMismatchException: Failed to convert property value of type [$Proxy1 implementing com.centerm.service.rightmanage.ISysUserService,com.centerm.service.rightmanage.ISysUser4Dwr,org.springframework.aop.SpringProxy,org.springframework.aop.framework.Advised] to required type [com.centerm.service.rightmanage.Impl.SysUserService] for property 'sysUserService'; nested exception is java.lang.IllegalArgumentException: Cannot convert value of type [$Proxy1 implementing com.centerm.service.rightmanage.ISysUserService,com.centerm.service.rightmanage.ISysUser4Dwr,org.springframework.aop.SpringProxy,org.springframework.aop.framework.Advised] to required type [com.centerm.service.rightmanage.Impl.SysUserService] for property 'sysUserService': no matching editors or conversion strategy found
上面的英文意思说无法将一个实现com.centerm.service.rightmanage.ISysUserService,com.centerm.service.rightmanage.ISysUser4Dwr,org.springframework.aop.SpringProxy,org.springframework.aop.framework.Advised接口的代理注入给com.centerm.service.rightmanage.Impl.SysUserService
之所以会出现这个问题是:因为我配置了aop拦截了sysUserService对象,Spring依照sysUserService对象生成其接口的代理,当把这接口的代理塞给sysUserService对象出错了
简化下如下:
MyBean implements IBean
ProxyBean implements IBean
myBean=ProxyBean 当然会出错
