Springboot集成Swagger2显示字段属性说明

新建spring boot工程

添加依赖

<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger2</artifactId>
<version>2.9.2</version>
</dependency>
<dependency>
<groupId>io.springfox</groupId>

<version>2.9.2</version>
</dependency>

新建swagger配置

import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.service.Contact;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

/**
* @author felix
* @ 日期 2019-05-27 12:03
*/
@Configuration
@EnableSwagger2
public class SwaggerConfiguration {
@Value("${swagger.enabled}")
private boolean enable;

@Bean
public Docket createRestApi() {
return new Docket(DocumentationType.SWAGGER_2)
.apiInfo(apiInfo())
.enable(enable)
.select()
.apis(RequestHandlerSelectors.basePackage("com.fecred.villagedoctor.controller"))
.paths(PathSelectors.any())
.build();
}

@Bean
public Docket healthApi() {
return new Docket(DocumentationType.SWAGGER_2)
.groupName("分组名称")
.apiInfo(apiInfo())
.enable(enable)
.select()
//分组的controller层
.apis(RequestHandlerSelectors.basePackage("com.xxx.controller"))
.paths(PathSelectors.regex(".*/health/.*"))
.build();
}

private ApiInfo apiInfo() {
return new ApiInfoBuilder()
.title("标题")
.description("一般描述信息")
.termsOfServiceUrl("http://localhost:8999/")
.contact(new Contact("联系人", "邮箱", "邮箱"))
.version("1.0")
.build();
}
}

新建前后端响应工具类

import io.swagger.annotations.ApiModelProperty;
import lombok.Data;

/**
* @author ie
* @ 日期 2019-10-25 14:24
*/
@Data
public class Result<T> {
@ApiModelProperty(value = "状态值")
private int code;
@ApiModelProperty(value = "提示信息")
private String message;
@ApiModelProperty(value = "结果")
private T payload;

private Result<T> code(int code) {
this.code = code;
return this;
}

private Result<T> message(String message) {
this.message = message;
return this;
}

private Result<T> payload(T payload) {
this.payload = payload;
return this;
}

public static <T> Result<T> ok() {
return new Result<T>().code(ResultCode.SUCCESS.getCode()).message(ResultCode.SUCCESS.getMessage()).payload(null);
}

public static <T> Result<T> ok(T payLoad) {
return new Result<T>().code(ResultCode.SUCCESS.getCode()).message(ResultCode.SUCCESS.getMessage()).payload(payLoad);
}

public static <T> Result<T> fail() {
return new Result<T>().code(ResultCode.FAIL.getCode()).message(ResultCode.FAIL.getMessage()).payload(null);
}

public static <T> Result<T> result(int code, String message, T payload) {
return new Result<T>().code(code).message(message).payload(payload);
}
}

状态码

@Getter
public enum ResultCode {
//成功
SUCCESS(20000, "成功"),
//失败
FAIL(40000, "失败"),
//未认证（签名错误）
UNAUTHORIZED(40001, "未认证（签名错误）"),
//接口不存在
NOT_FOUND(40004, "接口不存在"),
//服务器内部错误
INTERNAL_SERVER_ERROR(50000, "服务器内部错误"),
//TOKEN已过期
TOKEN_INVAILD(10001, "TOKEN已过期"),
//TOKEN无效
TOKEN_NOTFOUND(10002, "TOKEN无效");
private final int code;
private final String message;

ResultCode(int code, String message) {
this.code = code;
this.message = message;
}
}

Controller 层使用

@GetMapping(value = "/detail")
@ApiOperation(value = "根据id查询用户")
public Result<User> detail(@RequestParam("userId") Long userId) {
log.info("根据userId查询用户信息【{}】", userId);
User user = userService.findByUserId(userId);
log.info("用户信息【{}】", user.toString());
return Result.ok(user);
}

PageInfo 封装

用于 PageHelper显示属性值

import com.github.pagehelper.Page;
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;

import java.util.Collection;
import java.util.List;

/**

#对pagehelp的使用方式

@GetMapping(value = "/list")
@ApiOperation(value = "获取用户列表")
public ResponseData<MyPageInfo<User>> getList(@RequestParam(value = "page", defaultValue = "1") Integer page, @RequestParam(value = "size", defaultValue = "10") Integer size) {
PageHelper.startPage(page, size);
List<User> list = userService.getList();
log.info("查询用户列表记录数为 ：【{}】", list.size());
MyPageInfo<User> pageInfo = new MyPageInfo<>(list);
return ResultGenerator.successResult(pageInfo);
}
