swagger使用教程
本文将介绍RESTful API的重磅好伙伴Swagger2，它可以轻松的整合到Spring Boot中，并与Spring MVC程序配合组织出强大RESTful API文档。它既可以减少我们创建文档的工作量，同时说明内容又整合入实现代码中，让维护文档和修改代码整合为一体，可以让我们在修改代码逻辑的同时方便的修改文档说明。另外Swagger2也提供了强大的页面测试功能来调试每个RESTful API.

pom引入依赖
<!--添加Swagger依赖 -->
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger2</artifactId>
<version>2.7.0</version>
</dependency>
<!--添加Swagger-UI依赖 -->
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger-ui</artifactId>
<version>2.7.0</version>
</dependency>
swagger配置类设置
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.service.Contact;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;
@Configuration //标记配置类
@EnableSwagger2 //开启在线接口文档
public class Swagger2Config {
@Bean
public Docket createRestApi() {
return new Docket(DocumentationType.SWAGGER_2)
.apiInfo(apiInfo())
.select()
.apis(RequestHandlerSelectors.basePackage("com"))//扫描com路径下的api文档
.paths(PathSelectors.any())//路径判断
.build();
}
private ApiInfo apiInfo() {
return new ApiInfoBuilder()
.title("Swagger 开发规范")//标题
.description("Saggger 开发规范详文档细地址 ：http://www.baidu.com")//描述
.termsOfServiceUrl("https://swagger.io/irc/")//（不可见）条款地址
.contact(new Contact("人字拖", null, null))
.version("6.6.6")//版本号
.build();
}
}
web层接口注解
@Api("HystrixController测试swagger2")
@RequestMapping("/H")
@RestController
public class HystrixController {
private final Logger log = LoggerFactory.getLogger(this.getClass());
@ApiOperation("a方法")
@RequestMapping(name = "a",value = "/a",method = {RequestMethod.POST})
public String a(){
System.out.println("this is a");
log.info("this is a");
return "this is a";
}
@ApiOperation("获取list列表")
@ApiImplicitParams({@ApiImplicitParam(paramType = "body", name = "list", value = "list参数", required = false),@ApiImplicitParam(paramType = "body", name = "name", value = "姓名参数", required = false) })
@RequestMapping(name = "getList",value = "/getList",method = {RequestMethod.POST})
public List getList(@RequestBody(required = false) List<Integer> list,@RequestBody(required = false)String name){
//return Arrays.asList("1","2","3","4","5");
List list1 = list;
return list1;
}
}
Swagger注解基本使用
- @Api 描述类/接口的主要用途
- @ApiOperation 描述方法用途
- @ApiImplicitParam 描述方法的参数
- @ApiImplicitParams 描述方法一组参数(Multi-Params)
- @ApiIgnore 忽略某类/方法/参数的文档
swagger页面汉化
-
在src/main/resources目录下创建META-INF\resources目录，然后创建一个名称为"swagger-ui.html" 的HTML文件。如图：
image - 接下来将下面这段内容原封不动的拷贝进去。
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">

更详细的译文翻译（非必需）
如果想进一步调整译文，可以在META-INF\resources\webjars\springfox-swagger-ui\lang 目录下添加zh-cn.js文件.

然后在译文（zh-cn.js ）根据个人喜好来添加翻译内容，如下
'use strict';
/* jshint quotmark: double */
window.SwaggerTranslator.learn({
"Warning: Deprecated":"警告：已过时",
"Implementation Notes":"实现备注",

"Unable to read api":"无法读取api",
"from path":"从路径",
"server returned":"服务器返回"
});
==swagger页面无法访问，页面404，解决方案：==
springboot没有配置swagger静态页面访问，在WebMvcConfigurer中配置资源目录就可以了，代码如下：
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("swagger-ui.html")
.addResourceLocations("classpath:/META-INF/resources/swagger-ui.html");
registry.addResourceHandler("/webjars/**")
.addResourceLocations("classpath:/META-INF/resources/webjars/");
}
