swagger 3.0 学习笔记

引入pom

        <dependency><groupId>io.springfox</groupId><artifactId>springfox-boot-starter</artifactId><version>3.0.0</version></dependency>

可以加上全局请求参数

对象

ReqSwagger3VO

import io.swagger.v3.oas.annotations.media.Schema;
import lombok.Data;import java.io.Serializable;
import java.util.List;@Data
@Schema(name="ReqSwagger3VO",description ="swagger3对象" )
public class ReqSwagger3VO implements Serializable {private static final long serialVersionUID = 646541L;@Schema(description = "字符串",example = "aaaa")private String dataStr;@Schema(description = "数字",example = "1111")private Integer dataInt;@Schema(description = "字符数组" )private List<String> listStr;@Schema(description = "数字数组")private List<Integer> listInt;@Schema(description = "用户")private User user;@Schema(description = "用户数组")private  List<User> userList;@Schema(hidden = true)private String hiddenStr;private String hiddenNotStr;
}

User

import io.swagger.v3.oas.annotations.media.Schema;
import lombok.AllArgsConstructor;
import lombok.Data;
//https://www.cnblogs.com/antLaddie/p/17418078.html
@Schema(description ="用户信息" )
@Data
@AllArgsConstructor
public class User {@Schema(description = "姓名",example = "张三")private String name;@Schema(description = "年龄",example = "18", format = "int32")private int age;@Schema( description = "学生分数属性", format = "double", example = "55.50")private Double fraction;
}
