关于Shiro整合SpringBoot中，开发遇到的问题

public class AuthRealm extends AuthorizingRealm {

    @Autowired
    private UserService userService;

    //认证登录
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
　　　　 System.out.println("进入认证登录");
       // doGetAuthorizationInfo(null);
        UsernamePasswordToken usernamePasswordToken = (UsernamePasswordToken) token;
        String username = usernamePasswordToken.getUsername();
        User user = userService.findByUsername(username);
        return new SimpleAuthenticationInfo(user,user.getPassword(), this.getClass().getName());
    }

    //授权
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
        System.out.println("进入授权");
        User user = (User)principals.fromRealm(this.getClass().getName()).iterator().next();
        List<String> permissionList = new ArrayList<>();
        List<String> roleNameList = new ArrayList<>();
        Set<Role> roleSet = user.getRoles();
        if(!CollectionUtils.isEmpty(roleSet)){
            for (Role role :roleSet) {
                roleNameList.add(role.getRname());
                Set<Permission> permissionSet = role.getPermissions();
                if(!CollectionUtils.isEmpty(permissionSet)){
                    for (Permission permission: permissionSet) {
                        permissionList.add(permission.getPname());
                    }
                }
            }
        }
        SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();

        info.addRoles(roleNameList);    //获得各用户所相对应的角色
        info.addStringPermissions(permissionList);
        return info;
    }

}
