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：
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>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。
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(); } }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/**"/>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; } }启动项目，查看结果：
