一、背景介绍

1.1.项目简介

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。该框架最主要的功能是将Controller的方法进行可视化的展现,像方法注释,方法参数,方法返回值等都提供了相应的用户界面,尤其是对JSON参数的支持。同时可以结合swagger-ui可以对用户界面进行不同程度的定制,也可以对方法进行一个简单的测试。

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,自动在本类上下文加载一些环境变量信息
  • @EnableWebMvc 
  • @EnableSwagger 使swagger生效
  • @ComponentScan("com.myapp.packages") 需要扫描的包路径

 也可以自己不写配置类,直接使用默认的实现类,在Spring的配置文件中共配置:(不推荐

<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
1

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

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的方法参数描述

2.2.6.启动中间件

项目配置了Jetty或者Tomcat等Web容器的话,在对应的Controller配置好的话就可以启动看效果了。

2.2.7.需求定制

  • 分组信息定制
  • Url定制
  • Http相应定制

 

三、学习感想

Swagger很好的为我们在开发RESTful框架应用时,前后台分离的情况下提供了很有效的解决方案,上手迅速,操作简单,界面精简,功能完善,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,改变了以前的学习方法,收获了很多,同时也也得感谢国外友人的悉心帮助~技术无国界~


在公司的Wiki上写的博文,因为外面访问不了公司的内网,故贴过来给需要的小伙伴们分享一下。

可以在网站(www.sosoapi.com)上试下在线表单方式编写swagger-ui对应的json哈,编辑简单而且可以在线预览和导入导出,挺方便的
