因为公司使用的spring版本太高，在集成swagger的时候会存在一些问题，而网上的很多实例大多都是版本比较低的，为了使朋友们少踩坑，我这边将集成的过程记录一下：愿意了解源码的朋友直接求求交流分享技术二一四七七七五六三三

1. 引入spring、swagger的相关jar包（springfox-swagger2、springfox-swagger-ui），在pom.xml中配置：

<dependency>  <groupId>io.springfox</groupId>  <artifactId>springfox-swagger2</artifactId>  <version>2.4.0</version>  <exclusions>  <exclusion>  <groupId>org.springframework</groupId>  <artifactId>spring-core</artifactId>  </exclusion>  <exclusion>  <groupId>org.springframework</groupId>  <artifactId>spring-beans</artifactId>  </exclusion>  <exclusion>  <groupId>org.springframework</groupId>  <artifactId>spring-context</artifactId>  </exclusion>  <exclusion>  <groupId>org.springframework</groupId>  <artifactId>spring-context-support</artifactId>  </exclusion>  <exclusion>  <groupId>org.springframework</groupId>  <artifactId>spring-aop</artifactId>  </exclusion>  <exclusion>  <groupId>org.springframework</groupId>  <artifactId>spring-tx</artifactId>  </exclusion>  <exclusion>  <groupId>org.springframework</groupId>  <artifactId>spring-orm</artifactId>  </exclusion>  <exclusion>  <groupId>org.springframework</groupId>  <artifactId>spring-jdbc</artifactId>  </exclusion>  <exclusion>  <groupId>org.springframework</groupId>  <artifactId>spring-web</artifactId>  </exclusion>  <exclusion>  <groupId>org.springframework</groupId>  <artifactId>spring-webmvc</artifactId>  </exclusion>  <exclusion>  <groupId>org.springframework</groupId>  <artifactId>spring-oxm</artifactId>  </exclusion>  </exclusions>  </dependency>  <dependency>  <groupId>io.springfox</groupId>  <artifactId>springfox-swagger-ui</artifactId>  <version>2.4.0</version>  </dependency>
复制代码

提醒： 特别注意，springfox-swagger2在集成的时候，已经引入了spring的相关jar，特别是spring-context、spring-context-support的版本和项目中使用的版本完全不一致，项目在启动的时候出现很多包冲突的问题，这边在引入pom.xml文件的时候过滤掉了spring的相关jar包。

1. 编写Swagger的配置类：

package com.ml.honghu.swagger.web;  import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;  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;  @EnableWebMvc
@EnableSwagger2
@Configuration
@ComponentScan(basePackages ={"com.ml.honghu.**.rest"})
public class SwaggerConfig {  @Bean  public Docket createRestApi() {  return new Docket(DocumentationType.SWAGGER_2)  .apiInfo(apiInfo())  .select()  .apis(RequestHandlerSelectors.basePackage("com.ml.honghu"))  .paths(PathSelectors.any())  .build();  }  private ApiInfo apiInfo() {  return new ApiInfoBuilder()  .title("接口列表 v1.0")  .description("接口信息")  .termsOfServiceUrl("http://honghu.com")  .contact(new Contact("", "", "HongHu"))  .version("1.1.0")  .build();  }
}
复制代码

1. 在spring-mvc.xml文件中进行过滤器的配置，过滤掉swagger的相关访问配置：

<mvc:exclude-mapping path="/swagger*/**"/>
<mvc:exclude-mapping path="/v2/**"/>
<mvc:exclude-mapping path="/webjars/**"/>
复制代码

1. 服务配置项

@Api("区域服务")
@RestController
@RequestMapping(value = "/rest/area")
public class AreaService  {  @Autowired  private AreaService areaService;  <span style="color: #ff0000;">@ApiOperation(value = "区域列表", httpMethod = "GET", notes = "区域列表")</span>  @IsLogin  @ResponseBody  @RequestMapping(value = "treeData", method = RequestMethod.GET)  public List<Map<String, Object>> treeData(  <span style="color: #ff0000;">@ApiParam(required = true, value = "区域ID")</span>  @RequestParam(required=false) String extId, HttpServletResponse response) {  List<Map<String, Object>> mapList = Lists.newArrayList();  List<Area> list = areaService.findAll();  for (int i=0; i<list.size(); i++){  Area e = list.get(i);  if (StringUtils.isBlank(extId) || (extId!=null && !extId.equals(e.getId()) && e.getParentIds().indexOf(","+extId+",")==-1)){  Map<String, Object> map = Maps.newHashMap();  map.put("id", e.getId());  map.put("pId", e.getParentId());  map.put("name", e.getName());  mapList.add(map);  }  }  return mapList;  }
}
复制代码
