Swagger与SpringBoot的整合

Swagger可视化API，不仅能查看API，还能测试

1.引入相关JAR

<dependency>
    <groupId>com.mangofactory</groupId>
    <artifactId>swagger-springmvc</artifactId>
    <version>1.0.2</version>
</dependency>
<dependency>
    <groupId>org.codehaus.jackson</groupId>
    <artifactId>jackson-mapper-asl</artifactId>
    <version>1.9.13</version>
</dependency>
<dependency>
    <groupId>org.codehaus.jackson</groupId>
    <artifactId>jackson-core-asl</artifactId>
    <version>1.9.13</version>
</dependency>

2.在启动类中加入Swagger相关代码（用的springboot）：

@EnableSwagger
public class AppServiceApplication {

    public static void main(String[] args) {
        SpringApplication application = new SpringApplication(AppServiceApplication.class);
        Set<Object> sourcesSet = new HashSet<Object>();
        sourcesSet.add("classpath:applicationContext.xml");

        application.setSources(sourcesSet);

        application.run(args);
    }

    private SpringSwaggerConfig springSwaggerConfig;

    /**
     * Required to autowire SpringSwaggerConfig
     */
    @Autowired
    public void setSpringSwaggerConfig(SpringSwaggerConfig springSwaggerConfig) {
        this.springSwaggerConfig = springSwaggerConfig;
    }

    /**
     * Every SwaggerSpringMvcPlugin bean is picked up by the swagger-mvc
     * framework - allowing for multiple swagger groups i.e. same code base
     * multiple swagger resource listings.
     */
    @Bean
    public SwaggerSpringMvcPlugin customImplementation() {
        return new SwaggerSpringMvcPlugin(this.springSwaggerConfig).apiInfo(apiInfo()).includePatterns(".*?");
    }

    private ApiInfo apiInfo() {
        ApiInfo apiInfo = new ApiInfo(
                "App Service API",
                "",
                "",
                "[email protected]",
                "",
                "");

        return apiInfo;
    }

3.在代码中添加相关APIAnnotation，如下：

<span style="font-size:18px;background-color: rgb(255, 255, 255);">@ResponseBody
    @RequestMapping(
            value = addUser, method = RequestMethod.POST, produces = application/json; charset=utf-8)
    @ApiOperation(value = 添加用户, httpMethod = POST, response = BaseResultVo.class, notes = add user)
    public String addUser(@ApiParam(required = true, name = postData, value = 用户信息json数据) @RequestParam(
            value = postData) String postData, HttpServletRequest request)
    {
        LOGGER.debug(String.format(at function, %s, postData));
        if (null == postData || postData.isEmpty())
        {
            return super.buildFailedResultInfo(-1, post data is empty!);
        }
 
        UserInfo user = JSON.parseObject(postData, UserInfo.class);
        int result = userService.addUser(user);
        return buildSuccessResultInfo(result);
    }</span>

说明：
其中@ApiOperation和@ApiParam为添加的API相关注解，个参数说明如下：
@ApiOperation(value = “接口说明”, httpMethod = “接口请求方式”, response = “接口返回参数类型”, notes = “接口发布说明”；其他参数可参考源码；
@ApiParam(required = “是否必须参数”, name = “参数名称”, value = “参数具体描述”

4.添加Swagger UI配置

在GitHub上下载SwaggerUI项目，将dist下所有内容拷贝到本地项目webapp下面，结果目录如下图所示：

修改index.html

将index.html中http://petstore.swagger.wordnik.com/v2/swagger.json修改为http://localhost:8080/{projectname}/api-docs

到此为止，所有配置完成，启动你的项目，访问http://localhost:8086/swagger/index.html即可看到如下所示页面：

但是swagger不建议像上面和代码混合在一块，建议swagger用yaml文件单独配置部署生成HTML文件
