Swagger使用总结
1. Swagger是什么?
官方说法:Swagger是一个规范和完整的框架,用于生成、描述、调用和可视化 RESTful 风格的 Web 服务。总体目标是使客户端和文件系统作为服务器以同样的速度来更新。文件的方法,参数和模型紧密集成到服务器端的代码,允许API来始终保持同步。
个人觉得,swagger的一个最大的优点是能实时同步api与文档。在项目开发过程中,发生过多次:修改代码但是没有更新文档,前端还是按照老旧的文档进行开发,在联调过程中才发现问题的情况(当然依据开闭原则,对接口的修改是不允许的,但是在项目不稳定阶段,这种情况很难避免)。
2. spring boot 集成 Swagger
目前维护的系统是基于springboot框架开发的,因此本文会详细描述springboot与swagger集成的过程。
3,Swagger使用步骤:
3.1 导入相关的maven依赖
io.springfox
springfox-swagger2
2.5.0
io.springfox
springfox-swagger-ui
2.5.0
io.springfox
springfox-staticdocs
2.5.0
3.2 创建相关实体,controller,响应对象,主要看其中的注解的使用。
1 ,@Api(description = "用户相关接口文档")每个controller上的注解,表示这个controller主要的业务模块
2,@ApiOperation(value = "用户首页", notes = "访问页面")每个方法的注解,表示这个方法的业务功能是什么
3, @ApiParam(name = "userName",value = "用户昵称",required = true)方法参数注解,表示这个在这个业务方法中的名称,生成后的文档对该字段的说明,同样支持对象类型(引用类型),通过@ApiModelProperty(value = "用户id", required = true)来说明引用类型每个属性的作用。
4,@RequestHeader("token") String token 这个注解可以获取和设置header的参数,如用户身份签名。

bean 这里需要注意,如果有boolean类型,要为其添加getXX
X和setXXX方法,不是isXXX,因为swagger不识别isXXX
package org.kewei.zhang.entites;

@ApiModel(value = "用户信息")
public class UserVo {
@ApiModelProperty(value = "用户id", required = true)
private long userId=10;

3.3 swagger添加配置信息@Configuration@EnableSwagger2
package org.kewei.zhang.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.stereotype.Component;
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;
/**
* @author: kewei.zhang
* @Date: 2017/12/5
* @Time: 下午3:04
* Description:
*/
@Configuration
@EnableSwagger2
@Component
public class SwaggerConfig {
@Bean
public Docket userApi() {
return new Docket(DocumentationType.SWAGGER_2)
.groupName("用户")
.select()
.apis(RequestHandlerSelectors.basePackage("org.kewei.zhang.controller"))// 选择那些路径和api会生成document,每个controller都需要添加
.paths(PathSelectors.any()) // 对所有路径进行监控
.build()
.apiInfo(userInfo());
}
private ApiInfo userInfo() {
ApiInfo apiInfo = new ApiInfo("用户相关接口",//大标题
"用户有关的接口,包括增加删除用户",//小标题
"0.1",//版本
"上海",
new Contact("zkw", "", ""),// 作者
"swagger url",//链接显示文字
""//网站链接
);
return apiInfo;
}
}
3.4 在浏览器中输入http://ip:port/your-app-root/swagger-ui.html即可生成相应的文档并可以随时测试。

图中的文字说明都是通过之前的注解添加进去的
上述是完成生成api文档的具体步骤,但是有这样几个问题值得大家思考。
接口文档生成,需要嵌入我们的项目中,对我们的代码有侵入,这一点现在避免不了,而且我们只希望用户在我们的测试环境去测试,不希望生成环境去生成文档,如何解决这个问题,方法有两种,如下:
在配置中做管理
@Configuration
@EnableSwagger2
@EnableWebMvc
@ComponentScan("com.XXX.controller")
public class SwaggerConfig{
@Autowired
ConfigService configService;
@Bean
public Docket customDocket() {
if(configService.getServerEnv() == ServerEnvEnum.ONLINE) {
return new Docket(DocumentationType.SWAGGER_2)
.apiInfo(apiInfoOnline())
.select()
.paths(PathSelectors.none())//如果是线上环境,添加路径过滤,设置为全部都不符合
.build();
}else {
return new Docket(DocumentationType.SWAGGER_2)
.apiInfo(apiInfo());
}
}
private ApiInfo apiInfo() {
return new ApiInfoBuilder()
.title("XXX系统")
.description("XXX系统接口")
.license("")
.licenseUrl("")
.termsOfServiceUrl("")
.version("1.0.0")
.contact(new Contact("","", ""))
.build();
}
private ApiInfo apiInfoOnline() {
return new ApiInfoBuilder()
.title("")
.description("")
.license("")
.licenseUrl("")
.termsOfServiceUrl("")
.version("")
.contact(new Contact("","", ""))
.build();
}
}
另一种方式是:
修改一下依赖,为了编译通过,单独把swagger-annotations拿出来,线上环境把springfox-swagger-ui的依赖配置成是provided,这样可以实现http://localhost/swagger-ui.html访问404。但是:http://localhost/v2/api-docs和http://localhost/swagger-resources等接口依然能够访问,尽管是空的!
io.swagger
swagger-annotations
${springfox-swagger-anno.version}
io.springfox
springfox-swagger2
${springfox-swagger.version}
io.springfox
springfox-swagger-ui
${swagger.scope}
${springfox-swagger.version}
