撸了今年阿里、网易和美团的面试，我有一个重要发现.......>>> 
Springfox的前身是swagger-springmvc，是一个开源的API doc框架，可以将我们的Controller的方法以文档的形式展现，基于Swagger。
官网地址：http://springfox.github.io/springfox/
2019/3/21更新:最新用程序员DD的springboot兼容包，很方便零配置.
https://github.com/SpringForAll/spring-boot-starter-swagger
1.maven依赖
io.springfox
springfox-swagger2
2.4.0
io.springfox
springfox-swagger-ui
2.4.0
2.配置
package com.example;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.context.request.async.DeferredResult;
import springfox.documentation.builders.PathSelectors;
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;
@Configuration
@EnableSwagger2
@SpringBootApplication
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
@Bean
public Docket testApi() {
return new Docket(DocumentationType.SWAGGER_2)
.groupName("test")
.genericModelSubstitutes(DeferredResult.class)
//.genericModelSubstitutes(ResponseEntity.class)
.useDefaultResponseMessages(false)
.forCodeGeneration(true)
.pathMapping("/test")//api测试请求地址
.select()
.paths(PathSelectors.regex("/common/.*"))//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(PathSelectors.regex("/comm.*"))//过滤的接口
.build()
.apiInfo(demoApiInfo());
}
private ApiInfo testApiInfo() {
Contact contact = new Contact("王念", "http://my.oschina.net/wangnian", "[email protected]");
ApiInfo apiInfo = new ApiInfo("某API接口",//大标题
"REST风格API",//小标题
"0.1",//版本
"www.baidu.com",
contact,//作者
"主页",//链接显示文字
""//网站链接
);
return apiInfo;
}
private ApiInfo demoApiInfo() {
Contact contact = new Contact("王念", "http://my.oschina.net/wangnian", "[email protected]");
ApiInfo apiInfo = new ApiInfo("某API接口",//大标题
"REST风格API",//小标题
"0.1",//版本
"www.baidu.com",
contact,//作者
"主页",//链接显示文字
""//网站链接
);
return apiInfo;
}
}
3.restful注解描述
package com.example.demo;
import io.swagger.annotations.ApiOperation;
import io.swagger.annotations.ApiParam;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.*;
import springfox.documentation.annotations.ApiIgnore;
/**
* Created by 王念 on 2016/4/25.
*/
@RestController
@RequestMapping("comm/")
public class Controller {
/**
* 简单接口描述
*
* @param userName
* @return
*/
@RequestMapping(value = "/demo1", method = RequestMethod.POST)
@ApiOperation(value = "测试接口1", notes = "简单接口描述 userName必填", code = 200, produces = "application/json")
public ModelMap getDemo(@RequestParam("userName") String userName) {
ModelMap map = new ModelMap();
map.addAttribute("userName", userName);
return map;
}
/**
* 参数描述
*
* @param userName
* @return
*/
@RequestMapping(value = "/demo2/{userName}", method = RequestMethod.POST)
@ApiOperation(value = "测试接口2", notes = "参数描述", code = 200, produces = "application/json")
public ModelMap getDemo2(@ApiParam(name = "userName", value = "编号", required = true) @PathVariable("userName") String userName) {
ModelMap map = new ModelMap();
map.addAttribute("userName", userName);
return map;
}
/**
* 接受对象
*
* @return
*/
@RequestMapping(value = "/demo3", method = RequestMethod.POST)
@ApiOperation(value = "测试接口3", notes = "接受对象", code = 200, produces = "application/json")
public ModelMap getDemoa(@RequestBody User user) {
ModelMap map = new ModelMap();
map.addAttribute("result", user);
return map;
}
@ApiIgnore //使用这个注解忽略这个接口
@RequestMapping(value = "/demo4", method = RequestMethod.POST)
public ModelMap getDemob(@RequestParam String content) {
ModelMap map = new ModelMap();
map.addAttribute("result", new java.util.Date());
return map;
}
}访问http://localhost:8080/swagger-ui.html 就能看到
notes里 换行用 HMLT的标签就行了，哈哈哈哈
