后台讲师管理模块-添加讲师

内容简介

一、自动填充

二、编写 controller

一、自动填充

1.在实体类上加注解

private Boolean isDeleted;

@ApiModelProperty(value ="创建时间")

@TableField(fill = FieldFill. INSERT)

private Date gmtCreate;

@ApiModelProperty(value = "更新时间" )

@TableField(fill = FieldFill. INSERT_UPDATE)

2.自动填充类

@Componentpublic class MyMeta0bjectHandler implements Meta0b jectHandler {

@0verride

public void insertFill (Meta0bject meta0bject) {

//属性名称，不是字段名对this.setFieldValByName(fieldName: "gmtCreate",new Date(), meta0bject) :this. setFieldValByName( fieldName: "gmtModified", new Date(), meta0bject) :

}

@0verride

public void updateFill (Meta0bject metaObject) {this. setFieldValByName ( fieldName: "gmtModified", new Date(), meta0bject) :

}

二、编写 controller

1.添加讲师接口的方法

@PostMapping ( "addTeacher" )

public R addTeacher(@RequestBody EduTeacher eduTeacher) {

boolean save = teacherService. save (eduTeacher) :

if(save) {

return R. ok() :

} else {

return R. error) :

}

1. 打开 swagger,点击添加讲师
   

/eduservice/teacher/addteacher

eduTeacher(去掉时间和id,因为时间是自动填充，id 为为生出来的)

{

"avatar": "string",

"career": "string",

"intro": "string",

"isDeleted": false,

"level": 0,

"name": "string1010",

"sort": 0

}

点击try it out!

{

"success"; true,

"code": 20000,

"message": "成功",

"date": ()

}
