思路
每个微服务引入各自的 swagger 文档,zuul 做对立整合。
模块
- 父工程
springcloud-parent
引入swagger-spring-boot-starter
依赖:
<!--swagger-spring-boot-->
<dependency>
<groupId>com.spring4all</groupId>
<artifactId>swagger-spring-boot-starter</artifactId>
<version>1.7.0.RELEASE</version>
</dependency>
留神:这里版本必须为 1.7,应用 1.9 会有抵触
- 会员模块
springcloud-api-member-service-impl
扫包
swagger:
base-package: com.baba.api.service.impl
在 MemberServiceImpl
中引入 swagger
相干注解,失常来说这部分应该写入 Controller
中,并且最好用 PostMapping
或者 GetMapping
注解,不然每个接口会呈现多个。这里只是演示:
@ApiOperation("获取会员相干信息")
@ApiImplicitParam(name = "name",value = "用户信息参数",required = true,dataType = "String")
@RequestMapping("/getMember")
public UserEntity getMember(@RequestParam("name") String name) {UserEntity userEntity = new UserEntity();
userEntity.setName(name);
userEntity.setPassword("123456");
return userEntity;
}
启动类 AppMember
退出 @EnableSwagger2Doc
- 订单模块
springcloud-api-order-service-impl
扫包
swagger:
base-package: com.baba.api
OrderServiceImpl
中引入 swagger
相干注解
// 订单服务接口
@Override
@ApiOperation("获取订单相干信息")
@RequestMapping("/getOrderInfo")
public String getOrderInfo() {System.out.println("getOrderInfo--> 线程池名称:" + Thread.currentThread().getName());
return "订单服务接口调用胜利!";
}
![上传中 …]()
启动类 AppOrder
退出 @EnableSwagger2Doc
- 网关
gateway
中同样引入swagger-spring-boot-starter
依赖
<!--swagger-spring-boot-->
<dependency>
<groupId>com.spring4all</groupId>
<artifactId>swagger-spring-boot-starter</artifactId>
<version>1.7.0.RELEASE</version>
</dependency>
留神:我这里还引入的 jaxb-api
依赖解决如下报错,这个和 jdk 版本有关系,我这里还须要引入以下依赖
Error creating bean with name 'xmlModelPlugin': Lookup method resolution failed;
<dependency>
<groupId>javax.xml.bind</groupId>
<artifactId>jaxb-api</artifactId>
<version>2.3.0</version>
</dependency>
TokenFilter
拦截器临时正文掉:
启动类 AppGateway
中 增加文档起源 并注入 @EnableSwagger2Doc
注解
package com.baba.wlb;
import com.spring4all.swagger.EnableSwagger2Doc;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.cloud.context.config.annotation.RefreshScope;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.cloud.netflix.zuul.EnableZuulProxy;
import org.springframework.cloud.netflix.zuul.filters.ZuulProperties;
import org.springframework.context.annotation.Primary;
import org.springframework.stereotype.Component;
import springfox.documentation.swagger.web.SwaggerResource;
import springfox.documentation.swagger.web.SwaggerResourcesProvider;
import java.util.ArrayList;
import java.util.List;
/**
* @Author wulongbo
* @Date 2021/1/28 11:52
* @Version 1.0
*/@SpringBootApplication
@EnableEurekaClient
@EnableZuulProxy
@EnableSwagger2Doc
public class AppGateway {
//@EnableZuulProxy 开启网关代理
public static void main(String[] args) {SpringApplication.run(AppGateway.class, args);
}
// zuul 配置可能应用 config 实现实时更新
@RefreshScope
@ConfigurationProperties("zuul")
public ZuulProperties zuulProperties(){return new ZuulProperties();
}
// 增加文档起源
@Component
@Primary class DocumentationConfig implements SwaggerResourcesProvider{
@Override
public List<SwaggerResource> get() {List resource = new ArrayList();
resource.add(swaggerResource("app-member","/api-member/v2/api-docs","2.0"));
resource.add(swaggerResource("app-order","/api-order/v2/api-docs","2.0"));
return resource;
}
private SwaggerResource swaggerResource(String name,String location,String version){SwaggerResource swaggerResource=new SwaggerResource();
swaggerResource.setName(name);
swaggerResource.setLocation(location);
swaggerResource.setSwaggerVersion(version);
return swaggerResource;
}
}
}
启动
顺次启动,Eureka server
(集群[8100,9100]),config server
,member 服务,order 服务,gateway
(集群[81,82]), 以及 nginx(80)。
启动胜利后应用 nginx 做服务转发拜访 http://localhost/swagger-ui.html
切换服务名称:
至此 Zuul 网关就治理到了整个微服务 Swagger 文档
