解决循环依赖

Java

今天使用JavaConfig配置Shiro的时候出现了

Error creating bean with name ‘getShiroFilter’: Requested bean is currently in creation: Is there an unresolvable circular reference?

在xml配置的时候一切正常，苦思冥想后找到原因：

ShiroRealm代码片段


public class ShiroRealm extends AuthorizingRealm {

    @Autowired
    private UserService userService;

    ...
}

改成这样：


public class ShiroRealm extends AuthorizingRealm {

    private UserService userService;

    public UserService getUserService() {
        return userService;
    }

    public void setUserService(UserService userService) {
        this.userService = userService;
    }

    ...
}

RootConfig 这样写：


public class ShiroRealm extends AuthorizingRealm {

    ...

    public ShiroRealm getShiroRealm() {
        //return new ShiroRealm();
        ShiroRealm shiroRealm=new ShiroRealm();
        shiroRealm.setUserService(new UserService());
        return shiroRealm;
    }

    ...
}
