因为springboot项目想使用jwt，每个restful接口都需要验证token的有效性，所以决定使用springboot+aop拦截所有请求进行token校验。

项目结构如下图:

1.pom.xml

    @Pointcut("execution(public * com.dingkai.account.controller..*(..))")
    public void controllerMethodPointcut(){}

    @Before("controllerMethodPointcut()") //指定拦截器规则
    public Object interceptor(JoinPoint jp){
        MethodSignature signature = (MethodSignature) jp.getSignature();
        Method method = signature.getMethod(); //获取被拦截的方法
        String methodName = method.getName(); //获取被拦截的方法名
        logger.info("interceptor ***************************");
        logger.info("methodName: "+methodName);
        return null;
    }
}

@CrossOrigin(origins = "*")
@Controller
public class LoginController {

    @Autowired
    private LoginService loginService;

    private final Logger logger = LogManager.getLogger(this.getClass());


    @GetMapping(value = "test")
    @ResponseBody
    public void test(){
        System.out.println();
    }

    @PostMapping(value = "login")
    @ResponseBody
    public void login(@RequestBody String jsonStr,HttpServletRequest request, HttpServletResponse response){
        String uuid=UuidUtil.getUUID();

        JSONObject jsonObject=JSONObject.parseObject(jsonStr);

        User user=loginService.login(
                jsonObject.getString("username"),
                MD5Util.MD5(jsonObject.getString("password"))
        );
        logger.info(uuid+" login ************************************");
        logger.info("user: "+user);
        //登陆失败
        if(user==null){
            ResponseUtil.RESPONSE(request,response,"104",uuid,"用户不存在",null);
        }
        //登陆成功
        else{
            String token = Jwts.builder()
                    .setSubject(user.getUsername())
                    .setExpiration(new Date(System.currentTimeMillis() + 60 * 60 * 24 * 1000))
                    .signWith(SignatureAlgorithm.HS512, "account")
                    .compact();
            response.addHeader("Authorization", token);
            ResponseUtil.RESPONSE(request,response,"0",uuid,"success",user);
        }
    }

}

运行项目并请求test接口
查看日志如下，说明springboot+aop已经成功，接下来只要在里面添加自己的token验证逻辑即可
