Spring中的注解 @RequestBody和@ResponseBody的使用和区别

package com.stu.eduservice.controller;

import com.stu.commonutils.ResultData;
import com.stu.eduservice.entity.vo.CourseVo;
import com.stu.eduservice.service.IEduCourseService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;

/**
 * <p>
 * 课程 前端控制器

 */
@RestController
@RequestMapping("/eduservice/course")
@CrossOrigin
public class EduCourseController {

    @Autowired
    private IEduCourseService eduCourseService;

    //添加课程基本信息
    //@RestController里包含了ResponseBody注解，如果controller不是@RestController而是@Controller，则这里需要加上ResponseBody注解
    @PostMapping("addCourseInfo")
    public ResultData addCourseInfo(@RequestBody CourseVo courseVo){

        eduCourseService.saveCourseInfo(courseVo);
        return ResultData.success();
    }

}
