上一篇《简单搭建SpringBoot项目》讲了简单的搭建SpringBoot 项目,而 SpringBoot 和 Swagger-ui 搭配在持续交付的前后端开发中意义重大,Swagger 规范和完整的框架,用于生成、描述、调用和可视化 RESTful 风格的 Web 服务,对调用方而言非常直观,接口也可以点击try it out!
按钮 进行调试,在实际开发中大大增加了开发效率。点击可了解更多 swagger 相关信息swagger-ui官网
pom.xml中增加:
<!-- Swagger -->

SwaggerConfig.java:
package com.example.swagger;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.context.request.async.DeferredResult;
import springfox.documentation.builders.ApiInfoBuilder;
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;
import static springfox.documentation.builders.PathSelectors.regex;
/**

*/
@Configuration
@EnableSwagger2
public class SwaggerConfig {
/**
* 可以定义多个组,比如本类中定义把test和demo区分开了
*/
@Bean
public Docket testApi() {
return new Docket(DocumentationType.SWAGGER_2)
.groupName("test")
.genericModelSubstitutes(DeferredResult.class)
// .genericModelSubstitutes(ResponseEntity.class)
.useDefaultResponseMessages(false)
.forCodeGeneration(true)
.pathMapping("/")// base,最终调用接口后会和paths拼接在一起
.select()
.paths((regex("/api/test/.*")))//过滤的接口
.build()
.apiInfo(testApiInfo());
}
@Bean
public Docket demoApi() {
return new Docket(DocumentationType.SWAGGER_2)
.groupName("demo")
.genericModelSubstitutes(DeferredResult.class)
// .genericModelSubstitutes(ResponseEntity.class)
.useDefaultResponseMessages(false)
.forCodeGeneration(false)
.pathMapping("/")
.select()
.paths((regex("/api/demo/.*")))//过滤的接口
.build()
.apiInfo(demoApiInfo());
}
private ApiInfo testApiInfo() {
return new ApiInfoBuilder()
.title("Test 类型 API")//大标题
.description("这是 Test 类型 API 描述")//详细描述
.version("1.0")//版本
.termsOfServiceUrl("NO terms of service")
.contact(new Contact("shuai", "http://www.jianshu.com/u/07b9ae164f95", "1119386572@qq.com"))//作者

.licenseUrl("http://www.apache.org/licenses/LICENSE-2.0.html")
.build();
}
private ApiInfo demoApiInfo() {
return new ApiInfoBuilder()
.title("Demo 类型 API")//大标题
.description("这是 Demo 类型 API 描述")//详细描述
.version("1.0")//版本
.termsOfServiceUrl("NO terms of service")

}
}
此时启动 SpringBoot 工程,在浏览器输入 http://localhost:8080/swagger-ui.html 即可看见:
在 SwaggerConfig.java 文件中配置了扫描接口的路径,只有符合标准的接口才会显示出来,
常见swagger注解一览与使用
- 最常用的5个注解
@Api:修饰整个类,描述Controller的作用
@ApiOperation:描述一个类的一个方法,或者说一个接口
@ApiParam:单个参数描述
@ApiModel:用对象来接收参数
@ApiProperty:用对象接收参数时,描述对象的一个字段 - 其它若干
@ApiResponse:HTTP响应其中1个描述
@ApiResponses:HTTP响应整体描述
@ApiIgnore:使用该注解忽略这个API
下面创建符合规范的接口:
TestController.java:
package com.example.controller;
import io.swagger.annotations.ApiOperation;
import io.swagger.annotations.ApiParam;
import org.springframework.http.MediaType;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
/**
* Created by shuai on 2017/5/22.
*/
@Controller
@RequestMapping("/api/test")
public class TestController {
@ResponseBody
@RequestMapping(value = "/user", method= RequestMethod.POST, produces= MediaType.APPLICATION_JSON_VALUE)
@ApiOperation(value="获取user", notes="根据id获取User的接口")
public String getUser(
@ApiParam(required=true, name="id", value="主键id") @RequestParam(name = "id", required=true) String id
){
return "success";
}
}
当对象作为入参时,需要创建一个对象,对象中要用到上面提到的@ApiModel @ApiModelProperty
等注解:
UserVo.java:
package com.example.vo;
import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
/**
* Created by shuai on 2017/5/22.
*/
@ApiModel(description = "用户的对象")
public class UserVo {
@ApiModelProperty("姓名")
private String name;
@ApiModelProperty("年龄")
private Integer age;
@ApiModelProperty("性别")
private String sex;
//
Get And Set Method...()
DemoController.java:
package com.example.controller;
import com.example.vo.UserVo;
import io.swagger.annotations.ApiOperation;
import io.swagger.annotations.ApiParam;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.http.HttpHeaders;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.*;
import springfox.documentation.annotations.ApiIgnore;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
import java.util.ArrayList;
import java.util.List;
/**
* Created by shuai on 2017/5/21.
*/
@Controller
@RequestMapping(value = "/api/demo")
public class DemoController {
@ResponseBody
@RequestMapping(value = "/getUser", method = RequestMethod.POST)
@ApiOperation(value="测试getUser", notes="getUser详细说明", response = UserVo.class)
public UserVo getCount(
@ApiParam( required = true, name = "user", value = "入参为User对象") @RequestBody UserVo user
) {
return user;
}
}
这样一个简单的 SpringBoot 和Swagger-ui 结合的工程就完成了,下面启动运行:
