报错异常

java.lang.NoSuchMethodException: java.util.List.() Required List parameter ‘list’ is not present

如果是POST请求的话，使用@RequestBody package cn.itcast.controller;

import cn.itcast.pojo.Student; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.PostMapping; import org.springframework.web.bind.annotation.RequestBody; import org.springframework.web.bind.annotation.RequestParam; import org.springframework.web.bind.annotation.RestController;

import java.util.List;

@RestController public class StudentController { @PostMapping("/students") public Student getStudent(@RequestBody List studentList){ return studentList.get(0); }

}
