菜鸡落泪：自己新建了一个模块，访问自己写的路由404

billwhite

我新建了一个user模块，并写了一个控制器：

package com.common.controller;

import com.alibaba.fastjson.JSONObject;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import lombok.extern.slf4j.Slf4j;
import org.jeecg.common.api.vo.Result;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

/**
* @program: jeecg-boot-parent
* @description: class_description
* @author: Bill
* @create: 2021/01/16 10:21
* @blog: webpro.ltd
*/
@Slf4j
@RestController
@RequestMapping("/user/demo")
@Api(tags="校园小镇前端API")
public class TestController {

    @ApiOperation("demo1")
    @GetMapping("/demo1")
    public String demo1(@RequestParam("id") String id) {
        return "接收到了ID:" + id;
    }

    @ApiOperation("demo2")
    @GetMapping("/demo2")
    public String demo2() {
        return "接收到了ID:";
    }

}

已经在shiro中排除拦截，但是显示404，以前只做过一个模块的springboot项目，求各位大佬帮助，谢谢！

This application has no explicit mapping for /error, so you are seeing this as a fallback.
