摘要

目录添加Maven依赖添加配置类在application.properties中添加配置添加控制类UserController请求对象类DTO响应对象类最后，上效果图最后还有个坑 添

添加maven依赖

<!-- 集成swagger2 -->
<dependency>
	<groupId>io.springfox</groupId>
	<artifactId>springfox-swagger2</artifactId>
	<version>2.9.2</version>
</dependency>
<dependency>
	<groupId>io.springfox</groupId>
	<artifactId>springfox-swagger-ui</artifactId>
	<version>2.9.2</version>
</dependency>
<!--Google很好用的一个类库-->
<dependency>
	<groupId>com.google.guava</groupId>
	<artifactId>guava</artifactId>
	<version>27.0.1-jre</version>
</dependency>

添加配置类

package top.lidaoyuan.hamster.api.config.swagger; 
import java.util.Arrays; 
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.WEB.bind.annotation.RequestMethod;
 
import io.swagger.annotations.ApiOperation;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.builders.ResponseMessageBuilder;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.service.ResponseMessage;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;
 
@Configuration
@EnableSwagger2
public class Swagger2Config {
 
	@Bean
	public Docket customDocket() {
 
		// 配置全局参数返回状态
		java.util.List<ResponseMessage> resMsgList = Arrays.asList(
				new ResponseMessageBuilder().code(200).message("成功！").build(),
				new ResponseMessageBuilder().code(-1).message("失败！").build(),
				new ResponseMessageBuilder().code(401).message("参数校验错误！").build(),
				new ResponseMessageBuilder().code(403).message("没有权限操作，请后台添加相应权限！").build(),
				new ResponseMessageBuilder().code(500).message("服务器内部异常，请稍后重试！").build(),
				new ResponseMessageBuilder().code(501).message("请登录！").build());
 
		return new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfo()).select()
				.apis(RequestHandlerSelectors.withMethodAnnotation(ApiOperation.class))
				.paths(PathSelectors.any())
				.build()
				.globalResponseMessage(RequestMethod.GET, resMsgList)
				.globalResponseMessage(RequestMethod.POST, resMsgList)
				.globalResponseMessage(RequestMethod.PUT, resMsgList)
				.globalResponseMessage(RequestMethod.DELETE, resMsgList);
	}
 
	private ApiInfo apiInfo() {
		return new ApiInfoBuilder()
				.title("Hamster接口文档")
				.description("接口文档说明")
				.version("1.0.0")
				.build();
	} 
}

在application.properties中添加配置

logging.level.io.swagger.models.parameters.AbstractSerializableParameter=ERROR

添加控制类UserController

请求对象类DTO

package top.lidaoyuan.hamster.api.dto;

}

响应对象类

@JsonInclude(Include.NON_NULL)
public class JsonResultDTO {
	
	@ApiModelProperty(value = "状态码；200:成功")
	private Integer code;

	private String msg;
	
	@ApiModelProperty(value = "总记录数")

	}	
	
	public static JsonResultDTO ok() {
		return new JsonResultDTO(200, "成功");
	}
	
	public static JsonResultDTO ok(String msg) {

	}

	}
	
	public static JsonResultDTO error() {

	} 
}

最后，上效果图

请求路径Http://localhost:8080/swagger-ui.html

请求

响应

最后还有个坑

在使用最新版的springfox-swagger2 2.9.2``position排序的时候没有生效，后来在网上找了相关资料，需要重写swagger的两个类，具体如下。

@Primary //同一个接口，可能会有几种不同的实现类，而默认只会采取其中一种的情况下
@Component("ServiceModelToSwagger2Mapper")
@Order(Ordered.HIGHEST_PRECEDENCE)
public class CustomModelToSwaggerMapper extends ServiceModelToSwagger2MapperImpl {
 
    @Override
    protected List<Parameter> parameterListToParameterList(List<springfox.documentation.service.Parameter> list) {
        //list需要根据order|postion排序
        list = list.stream().sorted((p1, p2) -> Integer.compare(p1.getOrder(), p2.getOrder())).collect(Collectors.toList());
//        log.debug("************************************list:{}", list.toString());
        return super.parameterListToParameterList(list);
    }
