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>

                </exclusion>  
                <exclusion>

                </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>

                </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。

2. 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();  
    }  
}  

3. 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/**"/> 

4. 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：
