swagger,中文“拽”的意思。它是一个功能强大的api框架,它的集成非常简单,不仅提供了在线文档的查阅,而且还提供了在线文档的测试。另外swagger很容易构建restful风格的api,简单优雅帅气,正如它的名字。
一、引入依赖
<dependency> <groupId>io.springfox</groupId> <artifactId>springfox-swagger2</artifactId> <version>2.6.1</version> </dependency> <dependency> <groupId>io.springfox</groupId> <artifactId>springfox-swagger-ui</artifactId> <version>2.6.1</version> </dependency>
二、写配置类
@Configuration @EnableSwagger2 public class Swagger2 { @Bean public Docket createRestApi() { return new Docket(DocumentationType.SWAGGER_2)
.apiInfo(apiInfo())
.select()
.apis(RequestHandlerSelectors.basePackage("com.forezp.controller"))
.paths(PathSelectors.any())
.build();
} private ApiInfo apiInfo() { return new ApiInfoBuilder()
.title("springboot利用swagger构建api文档")
.description("简单优雅的restfun风格,http://blog.csdn.net/forezp")
.termsOfServiceUrl("http://blog.csdn.net/forezp")
.version("1.0")
.build();
}
}
通过@Configuration注解,表明它是一个配置类,@EnableSwagger2开启swagger2。apiINfo()配置一些基本的信息。apis()指定扫描的包会生成文档。
三、写生产文档的注解
swagger通过注解表明该接口会生成文档,包括接口名、请求方法、参数、返回信息的等等。
现在通过一个栗子来说明:
package com.forezp.controller; import com.forezp.entity.Book; import io.swagger.annotations.ApiImplicitParam; import io.swagger.annotations.ApiImplicitParams; import io.swagger.annotations.ApiOperation; import org.springframework.ui.ModelMap; import org.springframework.web.bind.annotation.*; import springfox.documentation.annotations.ApiIgnore; import java.util.*; /**
* 用户创建某本图书 POST /books/
* 用户修改对某本图书 PUT /books/:id/
* 用户删除对某本图书 DELETE /books/:id/
* 用户获取所有的图书 GET /books
* 用户获取某一图书 GET /Books/:id
* Created by fangzhipeng on 2017/4/17.

*/ @RestController @RequestMapping(value = "/books") public class BookContrller {
Map<Long, Book> books = Collections.synchronizedMap(new HashMap<Long, Book>()); @ApiOperation(value="获取图书列表", notes="获取图书列表") @RequestMapping(value={""}, method= RequestMethod.GET) public List<Book> getBook() {
List<Book> book = new ArrayList<>(books.values()); return book;
} @ApiOperation(value="创建图书", notes="创建图书") @ApiImplicitParam(name = "book", value = "图书详细实体", required = true, dataType = "Book") @RequestMapping(value="", method=RequestMethod.POST) public String postBook(@RequestBody Book book) {
books.put(book.getId(), book); return "success";
} @ApiOperation(value="获图书细信息", notes="根据url的id来获取详细信息") @ApiImplicitParam(name = "id", value = "ID", required = true, dataType = "Long",paramType = "path") @RequestMapping(value="/{id}", method=RequestMethod.GET) public Book getBook(@PathVariable Long id) { return books.get(id);
} @ApiOperation(value="更新信息", notes="根据url的id来指定更新图书信息") @ApiImplicitParams({ @ApiImplicitParam(name = "id", value = "图书ID", required = true, dataType = "Long",paramType = "path"), @ApiImplicitParam(name = "book", value = "图书实体book", required = true, dataType = "Book")
}) @RequestMapping(value="/{id}", method= RequestMethod.PUT) public String putUser(@PathVariable Long id, @RequestBody Book book) {
Book book1 = books.get(id);
book1.setName(book.getName());
book1.setPrice(book.getPrice());
books.put(id, book1); return "success";
} @ApiOperation(value="删除图书", notes="根据url的id来指定删除图书") @ApiImplicitParam(name = "id", value = "图书ID", required = true, dataType = "Long",paramType = "path") @RequestMapping(value="/{id}", method=RequestMethod.DELETE) public String deleteUser(@PathVariable Long id) {
books.remove(id); return "success";
} @ApiIgnore//使用该注解忽略这个API @RequestMapping(value = "/hi", method = RequestMethod.GET) public String jsonTest() { return " hi you!";
}
}
通过相关注解,就可以让swagger2生成相应的文档。如果你不需要某接口生成文档,只需要在加@ApiIgnore注解即可。需要说明的是,如果请求参数在url上,@ApiImplicitParam 上加paramType = “path” 。
