思路
每个微服务引入各自的swagger文档,zuul做统一整合。
模块
- 父工程
springcloud-parent
引入swagger-spring-boot-starter
依赖:
com.spring4all
swagger-spring-boot-starter
1.7.0.RELEASE
注意:这里版本必须为1.7,使用1.9会有冲突
- 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
相关注解,正常来说这部分应该写入Controller
中,并且最好用PostMapping
或者GetMapping
注解,不然每个接口会出现多个。这里只是演示:
@ApiOperation("获取会员相关信息")
@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
加入 @EnableSwagger2Doc
- 订单模块
springcloud-api-order-service-impl
扫包
swagger:
base-package: com.baba.api
OrderServiceImpl
中引入 swagger
相关注解
// 订单服务接口
@Override
@ApiOperation("获取订单相关信息")
@RequestMapping("/getOrderInfo")
public String getOrderInfo() {
System.out.println("getOrderInfo-->线程池名称:" + Thread.currentThread().getName());
return "订单服务接口调用成功!";
}
![上传中...]()
启动类 AppOrder
加入 @EnableSwagger2Doc
- 网关
gateway
中同样引入swagger-spring-boot-starter
依赖
com.spring4all
swagger-spring-boot-starter
1.7.0.RELEASE
注意: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,我这里还需要引入以下依赖
Error creating bean with name 'xmlModelPlugin': Lookup method resolution failed;
javax.xml.bind
jaxb-api
2.3.0
TokenFilter
拦截器暂时注释掉:
启动类 AppGateway
中 添加文档来源 并注入 @EnableSwagger2Doc
注解
package com.baba.wlb;
import com.spring4all.swagger.EnableSwagger2Doc;

import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
* @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配置能够使用config实现实时更新
@RefreshScope
@ConfigurationProperties("zuul")
public ZuulProperties zuulProperties(){
return new ZuulProperties();
}
// 添加文档来源
@Component
@Primary class DocumentationConfig implements SwaggerResourcesProvider{
@Override
public List 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
依次启动,Eureka server
(集群[8100,9100]),config server
,member服务,order服务,gateway
(集群[81,82]),以及nginx(80)。
启动成功后使用nginx做服务转发访问 http://localhost/swagger-ui.html
切换服务名称:
至此 Zuul网关就管理到了整个微服务Swagger文档
