占位符的方式和GET参数的方式对比如下

	// 访问方式http://localhost:8082/admin/555555
    @RequestMapping(value = "/{id}", method = RequestMethod.GET)
    public Admin getAccountById(@PathVariable("id") String id) {
        return adminService.findAdminById(id);
    }
    // 访问方式 http://localhost:8082/admin/?id=555555
    @GetMapping
    public Admin getAccountById(@RequestParam("id") String id) {
        return adminService.findAdminById(id);
    }

RequestParam
