使用@RequestParam 绑定List参数

@Data
public class User {
    private Integer id;
    private String name;
    private String password;
}

    @PostMapping("saveHomeworkRecords")
    public ResponseResult saveStudentHomeworkRecords(@RequestBody(required = true) List<User> users){
    	// 默认required=true，当List为空时会抛异常，导致无法进入方法体。required= false：表示当映射的List为空时不做异常捕抓；
        System.out.println(users);
        return ResponseResult.success("msg","");
    };

@Data
public class User {
    Long id;
    String username;
    Integer age;
}

@RestController
public class UserController {
    @PostMapping("saveUser")
    public ResponseResult saveUser(@RequestBody User user, @RequestParam("arrays") List<String > arrays, User  user1) {
        StringBuffer        sb   = new StringBuffer();
        for (String s:
             arrays) {
            sb.append(s+"   ");
        }
        return ResponseResult.success("插入成功！", sb.toString()+user.toString()+ user1.toString());
    }
