[html] view plain copy
- 最近参与公司接口编写,Android和IOS端都要调用这些接口,需要对接调试,如果没有一个接口文档,管理接口,别人用了接口,也不知道接口怎么用,接口上有什么参数,哪些是必须参数,哪些是非必须参数,于是研究了Swagger框架应用到项目中去,Swagger与Spring项目结合,Spring必须是4.0以上版本,下面是研究的小小demo:
1、引入Swagger的jar包,由于我的是Maven项目,所以在pom.xml中(注意Spring是4.0以上版本)
[html] view plain copy
- <dependency>
- <groupId>io.springfox</groupId>
- <artifactId>springfox-swagger2</artifactId>
- <version>2.0.2</version>
- </dependency>
- <dependency>
- <groupId>com.fasterxml.jackson.core</groupId>
- <artifactId>jackson-annotations</artifactId>
- <version>2.4.4</version>
- </dependency>
- <dependency>
- <groupId>com.fasterxml.jackson.core</groupId>
- <artifactId>jackson-databind</artifactId>
- <version>2.4.4</version>
- </dependency>
- <dependency>
- <groupId>com.fasterxml.jackson.core</groupId>
- <artifactId>jackson-core</artifactId>
- <version>2.4.4</version>
- </dependency>
2、新增Swagger配置代码
[java] view plain copy
- package cn.;
[java] view plain copy
- import org.springframework.context.annotation.Bean;
- import org.springframework.context.annotation.Configuration;
- import org.springframework.context.annotation.ComponentScan;
- import org.springframework.web.servlet.config.annotation.EnableWebMvc;
- import springfox.documentation.spi.DocumentationType;
- import springfox.documentation.spring.web.plugins.Docket;
- import springfox.documentation.swagger2.annotations.EnableSwagger2;
- @Configuration
- @EnableWebMvc
- @EnableSwagger2
- @ComponentScan(basePackages ={"com.test.api"})
- /**
- *
- * @author xiaozhou
- */
- public class SwaggerConfig {
- /**
- * Every Docket 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 Docket customDocket(){
- return new Docket(DocumentationType.SWAGGER_2);
- }
- }
3、修改applicationContext.xml
[html] view plain copy
- <bean class="cn.conf.SwaggerConfig"/>
4、增加一个测试的ContactController
[java] view plain copy
- @Api(value = "contacts-api", description = "有关于用户的CURD操作", position = 5)
- @Controller
- @RequestMapping("/contacts")
- public class ContactController {
- @Autowired ContactService contactService;
- @ResponseBody
- @RequestMapping(value="/1.0/contact/get.do/{id}",method=RequestMethod.GET)
- public Contact get(@PathVariable Long id) {
- return contactService.find(id);
- }
- @ApiOperation(value = "创建用户", notes = "返回用户实体对象", response = Contact.class, position = 2)
- @RequestMapping(value = "/1.0/contact/add.do", method=RequestMethod.POST)
- public void add(@RequestBody Contact contact,HttpServletResponse response) {
- contactService.create(contact);
- String location = ServletUriComponentsBuilder.fromCurrentRequest()
- .pathSegment("{id}").buildAndExpand(contact.getId())
- .toUriString();
- response.setHeader("Location",location);
- }
- @RequestMapping(value="/1.0/contact/update.do/{id}",method=RequestMethod.POST)
- @ApiResponses(value = {
- @ApiResponse(code = 200, message = "更新成功", response = Contact.class),
- @ApiResponse(code = 404, message = "找不到页面"),
- @ApiResponse(code = 500, message = "内部报错")}
- )
- public void update(@ApiParam(name="id", value="编号", required=true)@PathVariable Integer id,@RequestBody Contact contact) {
- contact.setId(id);;
- contactService.update(contact);
- }
- }
5、添加Swagger UI配置
从网上下载SwaggerUI项目,将dist下所有内容拷贝到本地项目webapp下面如下图
6、修改index修改index.html
将index.html中http://petstore.swagger.wordnik.com/v2/swagger.json修改为http://localhost:8080/v2/api-docs
7、启动项目,访问http://localhost:8080/v2/index.html即可看到如下所示页面:
