使用Spring boot开发RestFul 风格项目PUT/DELETE方法不起作用

在使用Spring boot 开发restful 风格的项目，put、delete方法不起作用，解决办法。

实体类Student

@Data
public class Student {

    private String id;
    private String name;
    private int age;
    private String sex;

    @Override
    public String toString() {
        return ToStringBuilder.reflectionToString(this);
    }
}

 

controller

@RestController
public class GreetingController {

    @RequestMapping(value = "/demo1/student", method = RequestMethod.POST)
    public void addStudent(Student student) {
        System.out.println(student);
        System.out.println("添加成功");
    }

    @RequestMapping(value = "/demo1/student", method = RequestMethod.PUT)
    public void updateStudent(Student student) {
        System.out.println(student);
        System.out.println("更新成功");
    }

    @RequestMapping(value = "/demo1/student", method = RequestMethod.GET)
    public Student getAtudentById(String id) {
        System.out.println("接收到的的参数" + id);
        Stuent s = new Student();
        s.setId("12");
        s.setName("google");
        s.setAge(12);
        return s;
    }


    @RequestMapping(value = "/demo1/student", method = RequestMethod.DELETE)
    public void delStudent(Student student) {
        System.out.println(student);
        System.out.println("删除成功");
    }

}

 

使用put 更新接口调用，参数无法传递过去。解决办法是在需要组装的参数前面添加注解 @RequestBody 

修改如下：

@RequestMapping(value = "/demo1/student", method = RequestMethod.PUT)
    public void updateStudent(@RequestBody Student student) {
        System.out.println(student);
        System.out.println("更新成功");
    }

即可成功调用

 

delete 接口修改方法相同
