    一、背景介绍

    1.1.项目简单介绍

    Swagger项目是由Dilip Krishnan和Adrian Kelly等人维护开发的一个为Spring Web MVC 项目提供方法文档的一个框架。该框架最基本的功能是将Controller的方法进行可视化的展现,像方法凝视。方法參数,方法返回值等都提供了对应的用户界面。尤其是对JSON參数的支持。同一时候能够结合swagger-ui能够对用户界面进行不同程度的定制,也能够对方法进行一个简单的測试。

    1.2.code repository

    1.3.演示项目

    二、开发准备

    2.1.环境准备

    • idea intellij 13+
    • Oracle java 1.6
    • Gradle 2.0 +

    2.2.项目搭建

    2.2.1.jar仓库

    Maven

    <repositories>
        <repository>
          <id>jcenter-release</id>
          <name>jcenter</name>
          <url>http://oss.jfrog.org/artifactory/oss-release-local/</url>
        </repository>
    </repositories>
     
    <dependency>
        <groupId>com.mangofactory</groupId>
        <artifactId>swagger-springmvc</artifactId>
        <version>1.0.0</version>
    </dependency>

    Gradle

    repositories {
        jcenter()
    }
     
    compile "com.mangofactory:swagger-springmvc:1.0.0"

    2.2.2.相关依赖

    • As of v0.9.5 all dependencies on scala have been removed.
    • Spring 3.2.x or above
    • jackson 2.4.4
    • guava 15.0

    2.2.3.编写配置文件

    编写一个Java文件,并使用注解:

    • @Configuration 配置注解,自己主动在本类上下文载入一些环境变量信息
    • @EnableWebMvc 
    • @EnableSwagger 使swagger生效
    • @ComponentScan("com.myapp.packages") 须要扫描的包路径

    演示样例:

    package org.bugkillers.back.swagger;
     
    import org.springframework.beans.factory.annotation.Autowired;
    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.DefaultServletHandlerConfigurer;
    import org.springframework.web.servlet.config.annotation.EnableWebMvc;
    import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
    import com.mangofactory.swagger.configuration.SpringSwaggerConfig;
    import com.mangofactory.swagger.models.dto.ApiInfo;
    import com.mangofactory.swagger.paths.SwaggerPathProvider;
    import com.mangofactory.swagger.plugin.EnableSwagger;
    import com.mangofactory.swagger.plugin.SwaggerSpringMvcPlugin;
    /**
     * 使用注解的方式来扫描API
     * 无需在Spring的xml配置文件来配置。由 @see @EnableWebMvc 取代
     * <p/>
     * <p> @author 刘新宇
     *
     * <p> @date 2015年1月30日 下午1:18:48
     * <p> @version 0.0.1
     */
    @Configuration
    @EnableWebMvc
    @EnableSwagger
    @ComponentScan(basePackages ={"com.ak.swaggerspringmvc.shared.controller", "com.ak.spring3.music"})
    public class CustomJavaPluginConfig extends WebMvcConfigurerAdapter {
       private SpringSwaggerConfig springSwaggerConfig;
       @Autowired
       public void setSpringSwaggerConfig(SpringSwaggerConfig springSwaggerConfig) {
          this.springSwaggerConfig = springSwaggerConfig;
       }
       /**
        * 链式编程 来定制API样式
        * 兴许会加上分组信息
        * @return
        */
       @Bean
       public SwaggerSpringMvcPlugin customImplementation(){
          return new SwaggerSpringMvcPlugin(this.springSwaggerConfig)
                .apiInfo(apiInfo())
                .includePatterns(".*")
    //            .pathProvider(new GtPaths())
                .apiVersion("0.0.1")
                .swaggerGroup("user");
       }
        private ApiInfo apiInfo() {
          ApiInfo apiInfo = new ApiInfo(
                  "bugkillers-back API",
                  "bugkillers 后台API文档",
                  "<a href="http://127.0.0.1:9081/api" "="" style="color: rgb(59, 115, 175); text-decoration: none; border-radius: 0px !important; border: 0px !important; bottom: auto !important; float: none !important; height: auto !important; left: auto !important; margin: 0px !important; outline: 0px !important; overflow: visible !important; padding: 0px !important; position: static !important; right: auto !important; top: auto !important; vertical-align: baseline !important;  auto !important; box-sizing: content-box !important; min-height: inherit !important; background: none !important;">http://127.0.0.1:9081/api",
                  "bugkillers@163.com",
                  "My License",
                  "My Apps API License URL"
            );
          return apiInfo;
        }
        @Override
        public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
          configurer.enable();
        }
         
        class GtPaths extends SwaggerPathProvider{
            @Override
            protected String applicationPath() {
                return "/restapi";
            }
            @Override
            protected String getDocumentationPath() {
                return "/restapi";
            }
        }
         
    }

     

     也能够自己不写配置类,直接使用默认的实现类,在Spring的配置文件里共配置:(不推荐

    1
    2
    <mvc:annotation-driven/> <!-- Required so swagger-springmvc can access spring's RequestMappingHandlerMapping  -->
    <bean class="com.mangofactory.swagger.configuration.SpringSwaggerConfig" />

     

    2.2.4.与swagger-ui集成

    方式一:

    • Note: Only use this option if you don't need to customize any of the swagger-ui static content, otherwise use option 2.
    • Use the web-jar which packages all of the swagger-ui static content.
    • Requires that your app is using the servlet 3 specification.
    • For non-spring boot applications some extra spring configuration (ResourceHandler's) is required. See: https://github.com/adrianbk/swagger-springmvc-demo/tree/master/swagger-ui

    3
    4
    dependencies {
      ...
      compile "org.ajar:swagger-spring-mvc-ui:0.4"
    }

    方式二:(推荐

    • Manually copy all of the static content swagger-ui's dist directory (https://github.com/wordnik/swagger-ui/tree/master/dist)
    • Provide the necessary view resolvers and resource handlers to serve the static content.
    • Consult the spring documentation on serving static resources.

    The following is one way to serve static content from /src/main/webapp

    1
    2
    3
    4
    5
    <!-- Direct static mappings -->
    <mvc:resources mapping="*.html" location="/"/>
     
    <!-- Serve static content-->
    <mvc:default-servlet-handler/>

    2.6.5.Controller配置

    使用注解对Controller进行配置:

    • @Api 配置方法API
    • @ApiOperation API的操作 GET PUT DELETE POST
    • @ApiParam API的方法參数描写叙述

    演示样例Controller:

    package org.bugkillers.back.user.controller;
    import java.util.List;
    import org.bugkillers.back.bean.User;
    import org.bugkillers.back.result.Result;
    import org.bugkillers.back.user.service.UserService;
    import org.bugkillers.back.util.ResultUtil;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.http.HttpStatus;
    import org.springframework.http.ResponseEntity;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.PathVariable;
    import org.springframework.web.bind.annotation.RequestBody;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RequestMethod;
    import org.springframework.web.bind.annotation.ResponseBody;
    import com.wordnik.swagger.annotations.Api;
    import com.wordnik.swagger.annotations.ApiOperation;
    import com.wordnik.swagger.annotations.ApiParam;
    /**
     * 用户操作Controller
     * <p/>
     * <p>
     *
     * @author 刘新宇
     *
     *         <p>
     * @date 2015年1月30日 上午10:50:34
     *       <p>
     * @version 0.0.1
     */
    @Api(value = "user-api", description = "有关于用户的CURD操作", position = 5)
    @Controller
    @RequestMapping("/user")
    public class UserController {
        @Autowired
        private UserService service;
        /**
         * 注冊用户
         * @param user
         */
        @ApiOperation(value = "注冊", notes = "注冊用户", position = 3)
        @ResponseBody
        @RequestMapping(value = { "/regist" }, method = RequestMethod.POST)
        public ResponseEntity<?

    > regist(@RequestBody User user) { service.save(user); Result<String> result = ResultUtil.buildSuccessResult("注冊成功"); return new ResponseEntity<Result<String>>(result, HttpStatus.OK); } /** * 依据pk查找用户 * @param userPk * @return */ @ApiOperation(value = "依据pk查找用户", notes = "返回用户实体对象", response = User.class, position = 2) @ResponseBody @RequestMapping(value = { "/{userPk}" }, method = RequestMethod.GET) public ResponseEntity<?> findByPk( @ApiParam(value = "填写Pk", allowableValues = "range[1,5]", required = true, defaultValue = "userPk", allowMultiple = true) @PathVariable("userPk") Integer userPk) { Result<User> result = ResultUtil.buildSuccessResult(service.findByPk(userPk)); return new ResponseEntity<Result<User>>(result, HttpStatus.OK); } /** * 測试 * @param who * @return */ @ApiOperation(value = "Hellow World", notes = "測试功能", position = 1) @ResponseBody @RequestMapping(value = { "/hello/{who}" }, method = RequestMethod.GET) public ResponseEntity<?

    > hello( @ApiParam(value = "填写名称") @PathVariable("who") String who) { Result<String> result = ResultUtil.buildSuccessResult( "Hello guys" + " " + who + "!"); return new ResponseEntity<Result<String>>(result, HttpStatus.OK); } /** * 查询全部 * @return */ @ApiOperation(value = "获取全部用户", notes = "返回用户实体对象集合", position = 5) @RequestMapping(value = "/findAll", method = RequestMethod.GET) public @ResponseBody ResponseEntity<?> findAll() { Result<List<User>> result = ResultUtil.buildSuccessResult( service.findAll()); return new ResponseEntity<Result<List<User>>>(result, HttpStatus.OK); } /** * 依据用户pk更新实体 * @param userPk 用户pk * @param user 返回更新后的实体 * @return */ @ApiOperation(value = "更新用户", notes = "返回更新的用户实体对象",position = 5) @RequestMapping(value = "/update/{userPk}", method = RequestMethod.PUT) public ResponseEntity<?> updateByPk( @PathVariable("userPk") Integer userPk, @RequestBody User user) { user.setPk_user(userPk); service.update(user); Result<User> result = ResultUtil.buildSuccessResult(user); return new ResponseEntity<Result<User>>(result, HttpStatus.OK); } /** * 依据用户pk删除实体 * @param userPk 用户pk * @return */ @ApiOperation(value = "删除用户", notes = "依据pk删除用户",position = 5) @RequestMapping(value = "/delete/{userPk}", method = RequestMethod.GET) public ResponseEntity<?> deleteByPk( @PathVariable("userPk") Integer userPk) { service.delete(userPk); Result<String> result = ResultUtil.buildSuccessResult("删除成功"); return new ResponseEntity<Result<String>>(result, HttpStatus.OK); } }



    2.2.6.启动中间件

    项目配置了Jetty或者Tomcat等Web容器的话,在相应的Controller配置好的话就能够启动看效果了。

    2.2.7.需求定制

    • 分组信息定制
    • Url定制
    • Http对应定制

     

    三、学习感想

    Swagger非常好的为我们在开发RESTful框架应用时,前后台分离的情况下提供了非常有效的解决方式。上手迅速,操作简单,界面精简,功能完好。满足各种定制化的需求,是在使用Spring MVC做Web开发时的不二选择。

    通过对swagger的学习。增强了英语交流的能力。改变了曾经的学习方法。收获了非常多,同一时候也也得感谢国外友人的悉心帮助~技术无国界~

    3.1  Guava工具类的使用  http://ifeve.com/google-guava/

    Guavaproject包括了若干被Google的 Java项目广泛依赖 的核心库,比如:集合 [collections] 、缓存 [caching] 、原生类型支持 [primitives support] 、并发库 [concurrency libraries] 、通用注解 [common annotations] 、字符串处理 [string processing] 、I/O 等等

    3.2  Gradle构建工具的使用  http://ifeve.com/google-guava/

    配置更加简洁。支持Maven,好多开源项目已经从Maven转到Gradle。

    3.3  Groovy语言 http://groovy.codehaus.org/User+Guide

    和scala、clojure等同是在JVM上执行的脚本语言,丰富的类库。和Java互通。能够作为Java程序猿的第二语言。

    3.4  链式编程 (return this

    Java中类似Swagger配置文件SwaggerSpringMvcPlugin

    JQuery中类似 $("#p1").css("color","red").slideUp(2000).slideDown(2000);
