- 最近參與公司接口編寫,Android和IOS端都要調用這些接口,需要對接調試,如果沒有一個接口文檔,管理接口,別人用了接口,也不知道接口怎么用,接口上有什么參數,哪些是必須參數,哪些是非必須參數,於是研究了Swagger框架應用到項目中去,Swagger與Spring項目結合,Spring必須是4.0以上版本,下面是研究的小小demo:
1、引入Swagger的jar包,由於我的是Maven項目,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配置代碼
[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、增加一個測試的ContactController
[java]
view plain
copy
- @Api(value = "contacts-api", description = "有關於用戶的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 = "創建用戶", notes = "返回用戶實體對象", 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 = "找不到頁面"),
- @ApiResponse(code = 500, message = "內部報錯")}
- )
- public void update(@ApiParam(name="id", value="編號", required=true)@PathVariable Integer id,@RequestBody Contact contact) {
- contact.setId(id);;
- contactService.update(contact);
- }
- }
5、 添加Swagger UI配置
從網上下載SwaggerUI項目,將dist下所有內容拷貝到本地項目webapp下面如下圖
6、修改index修改index.html
將index.html中http://petstore.swagger.wordnik.com/v2/swagger.json修改為http://localhost:8080/v2/api-docs
7、啟動項目,訪問http://localhost:8080/v2/index.html即可看到如下所示頁面:
