java.lang.IllegalArgumentException: Invalid character found in method name [0x160x030x010x020x000x01

springboot项目启动localhost 发送了无效的响应。

在初学springboot时刚启动springboot想要测试是否成功。

package com.itheima.controller;


import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

//Rest模式
@RestController
@RequestMapping("/books")
public class BookController {

    @GetMapping
    public String testById(){
        System.out.println("springboot is running...");
        return "springboot is running...";
    }

}

之后打开https://localhost:8080/books后报错了

 控制台显示：

在查找错误中得知，这个异常的意思就是在方法中有非法的参数，于是我觉得问题应该出在请求上。果然，我发现我写的ajax请求地址写的是 https，可是我并没有加密，是无法用https协议的，将https改为http即可。
