swagger升级版springboot集成在线文档knife4j
作者：互联网
自动生成文档框架.
步骤:
1.集成maven依赖
2.添加配置类,制定整个文档的署名,介绍等信息
3.编写接口类,视图实体类,结果映射类
4.启动项目,访问本地地址+端口+/doc.html(http://localhost:8080/doc.html) 具体可参考knife4j-spring-ui依赖内容
5.接口访问资源(用于接口调用,以后网关对接后可以汇总所有模块的文档,访问网关做到统一的访问在线文档)
分组接口：/swagger-resources 例如:localhost:8080/swagger-resources
详情实例接口：/v2/api-docs 例如:localhost:8080/v2/api-docs?group=user-group
集成,maven依赖:
springboot版本:
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.5.0</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>

接口,视图实体接收类,视图实体结果返回类
1.结果返回类
package com.example.springbootknife4j;
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;
import java.io.Serializable;
/**
* 我还没有写描述
*
* @author <发哥讲Java-694204477@qq.com>
* @version 1.0
* @date 2021/5/30 23:25
*/
@Data
public class Result<T> implements Serializable {
@ApiModelProperty(value = "响应码", name = "code")
private String code;
@ApiModelProperty(value = "响应消息", name = "msg")
private String msg;
@ApiModelProperty(value = "响应数据", name = "data")
private T data;
public static <T> Result<T> ok(T data) {
Result<T> result = new Result<>();
result.setCode("200");
result.setMsg("success");
result.setData(data);
return result;
}
}
记住最好使用泛型,然后在接口controller中最好指定好类型,然后会自动映射出视图类,并含有注释
2.视图实体接收类
package com.example.springbootknife4j.vo;
import com.fasterxml.jackson.annotation.JsonFormat;
import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import io.swagger.annotations.ApiParam;
import lombok.Data;
import lombok.experimental.Accessors;
import org.springframework.format.annotation.DateTimeFormat;
import java.util.Date;
/**
* TODO
*
* @author 发哥讲Java
* @version 1.0
* @date 2021-05-30 16:51
*/
@Data
@Accessors(chain = true)
@ApiModel("用户视图接收类 - userVo")
public class UserVo {
@ApiModelProperty(value = "主键", name = "id")
private String id;
@ApiModelProperty(value = "用户名", name = "username")
private String username;
@ApiModelProperty(value = "密码", name = "password")
private String password;
@DateTimeFormat(pattern = "yyyy-MM-dd HH:mm:ss")
@JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss", timezone = "GMT+8")
@ApiModelProperty(value = "创建日期", name = "crateTime")
private Date crateTime;
}
3.视图结果实体返回类
package com.example.springbootknife4j.vo;
import com.fasterxml.jackson.annotation.JsonFormat;
import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;
import lombok.experimental.Accessors;
import org.springframework.format.annotation.DateTimeFormat;
import java.io.Serializable;
import java.util.ArrayList;
import java.util.Date;
import java.util.List;
/**
* TODO
*
* @author 发哥讲Java
* @version 1.0
* @date 2021-05-30 16:51
*/
@Data
@Accessors(chain = true)
@ApiModel("用户实体类 - user")
public class User implements Serializable {
private static final long serialVersionUID = 1L;
@ApiModelProperty(value = "主键", name = "id")
private String id;
@ApiModelProperty(value = "用户名", name = "username")
private String username;
@ApiModelProperty(value = "密码", name = "password")
private String password;
@DateTimeFormat(pattern = "yyyy-MM-dd HH:mm:ss")
@JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss", timezone = "GMT+8")
@ApiModelProperty(value = "创建日期", name = "crateTime")
private Date crateTime;
/**
* 扩展
*/
@ApiModelProperty(value = "课程list")
private List<Course> courseList = new ArrayList<>();
}
package com.example.springbootknife4j.vo;
import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;
import lombok.experimental.Accessors;
import java.io.Serializable;
/**
* 我还没有写描述
*
* @author <发哥讲Java-694204477@qq.com>
* @version 1.0
* @date 2021/5/30 0:35
*/
@Data
@Accessors(chain = true)
@ApiModel("课程视图类 - CourseVo")
public class Course implements Serializable {
private static final long serialVersionUID = 1L;
@ApiModelProperty(value = "名称", name = "name")
private String name;
@ApiModelProperty(value = "课程id", name = "courseId")
private String courseId;
}
4.接口
package com.example.springbootknife4j.controller;
import com.example.springbootknife4j.Result;
import com.example.springbootknife4j.vo.Course;

@RestController
// 给整个类定义 tags, 将所有接口归档当前tags(菜单)下
// 给controller 起别名 类注解
@Api(tags = "测试API类 - hello")
public class HelloController {
// 方法的描述,
@GetMapping("/hello")
@ApiOperation(value = "访问hello接口")
@ApiOperationSupport(author = "发哥讲Java")//标注作者
@ApiImplicitParams(value = {
@ApiImplicitParam(name = "name", value = "姓名"),
@ApiImplicitParam(name = "age", value = "年龄"),
})
public Result<String> hello(String name, Integer age) {
System.out.println("name = " + name);
System.out.println("age = " + age);
return Result.ok(name + "--" + age);

// 方法的描述,
@GetMapping("/helloVo")
@ApiOperation(value = "访问复杂参数-hello接口")
@ApiOperationSupport(author = "发哥讲Java")//标注作者
public Result<String> helloVo(UserVo userVo) {
System.out.println("userVo = " + userVo);
return Result.ok(userVo.toString());

@PostMapping("/post")
@ApiOperation("复杂post请求接口")
@ApiOperationSupport(author = "发哥讲Java")//标注作者

// 构建user
User user = new User();
user.setId(UUID.randomUUID().toString())
.setUsername(userVo.getUsername())
.setPassword(userVo.getPassword())
.setCrateTime(userVo.getCrateTime());
// 构建 课程list
Course courseVo = new Course();
