Spring Cloud之Swagger集羣搭建

 在微服務中，Swagger是每一個服務 好比會員服務，訂單服務，支付服務 進行繼承、

如何將整個微服務中的Swagger進行合成，同一臺服務器上。

 

使用Zuul+Swagger實現管理整個微服務API文檔

使用Nginx+Swagger以不一樣的項目區分跳轉到不一樣的接口文檔

 

Spring Boot支持對Swagger管理，只須要Zuul網關添加對應服務Swagger文檔便可

 

服務配置

一、會員服務和訂單服務都引入對swagger的maven支持

        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>2.8.0</version>
        </dependency>
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>2.8.0</version>
        </dependency>

                  　　

 

等於：（Spring Boot已經整合好了）

<dependency>
<groupId>com.spring4all</groupId>
<artifactId>swagger-spring-boot-starter</artifactId>
<version>1.7.0.RELEASE</version>
</dependency>

　　

二者選擇其一

 

而後啓動類須要：

@EnableSwagger2Doc

 

接着,controller中須要：

類上註解

   @Api("訂單接口")

接口方法上

 @ApiOperation("訂單服務接口")
 @PostMapping("/getOrder")

 

yml加入掃包範圍：

swagger:
     base-package: com.toov5.api

 

（每一個服務都同樣）

 

如Member：

 

 

package com.toov5.api.service.impl;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

import com.toov5.api.entity.UserEntity;
import com.toov5.api.service.IMemberService;
import com.toov5.base.BaseApiService;
import com.toov5.base.ResponseBase;

import io.swagger.annotations.Api;
import io.swagger.annotations.ApiImplicitParam;
import io.swagger.annotations.ApiOperation;

  
@RestController
@Api("會員服務接口")
public class MemberServiceImpl extends BaseApiService implements IMemberService {
    @Value("${server.port}")
    private String serverPort; 
    
     @RequestMapping("/getMember")  
    public UserEntity getMember(@RequestParam("name") String name) {
        UserEntity userEntity = new UserEntity();
        userEntity.setName(name);
        userEntity.setAge(10);
        return userEntity;
    }
     
     @RequestMapping("/getUserInfo") 
     public ResponseBase getUserInfo() {
        try {
            Thread.sleep(1500);
        } catch (Exception e) {
            
        }
        return setResultSuccess("getUserInfo調用成功....");
    }
     
      
     @RequestMapping("/") 
     public String Index() {
        return "我是member"+serverPort;
    } 
     
        @ApiOperation(value = "獲取會員信息接口") // 具體描述
        @ApiImplicitParam(name = "userName", value = "用戶信息參數", required = true, dataType = "String") // 傳入的參數 ,描述 , 必須傳遞true                                                                                                    // , 類型String
        @GetMapping("/getMemberInfo")
        public String getMemberInfo(String userName) {
            System.out.println(userName);
            return "userName" + userName;
        }
 
}

啓動：

package com.toov5.api.service.impl;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.cloud.openfeign.EnableFeignClients;

import com.spring4all.swagger.EnableSwagger2Doc;

@SpringBootApplication (scanBasePackages={"com.toov5.*"})
@EnableEurekaClient
@EnableFeignClients
@EnableSwagger2Doc //開啓swagger文檔)
public class AppMember {
  public static void main(String[] args) {
    SpringApplication.run(AppMember.class, args);
}
}

yml

server:
  port: 8005

spring:
    application:
        name: app-toov5-member
ַ
eureka:
  client:
    service-url:
           defaultZone: http://localhost:8100/eureka

           

    register-with-eureka: true

    fetch-registry: true

swagger:
  base-package:  com.toov5.api.service.impl

　　

 

網關gateway配置：

也須要引入相同的pom

<dependency>
<groupId>com.spring4all</groupId>
<artifactId>swagger-spring-boot-starter</artifactId>
<version>1.7.0.RELEASE</version>
</dependency>

 

而後啓動類：

package com.toov5;

import java.util.ArrayList;
import java.util.List;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.cloud.netflix.zuul.EnableZuulProxy;
import org.springframework.context.annotation.Primary;
import org.springframework.stereotype.Component;

import com.spring4all.swagger.EnableSwagger2Doc;

import springfox.documentation.swagger.web.SwaggerResource;
import springfox.documentation.swagger.web.SwaggerResourcesProvider;

@SpringBootApplication
@EnableEurekaClient
@EnableZuulProxy  //開啓網關代理
@EnableSwagger2Doc  //開啓swagger
public class AppGateway {
   public static void main(String[] args) {
   SpringApplication.run(AppGateway.class, args);     
}

       // 添加文檔來源
 @Component @Primary class DocumentationConfig implements SwaggerResourcesProvider { public List<SwaggerResource> get() { List resources = new ArrayList<Object>(); //app-itmayiedu-order 
               resources.add(swaggerResource("app-toov5-member", "/api-member/v2/api-docs", "2.0")); // 第一個參數能夠隨便寫 第二個參考yml對應
               resources.add(swaggerResource("app-toov5-order", "/api-order/v2/api-docs", "2.0")); return resources; } private SwaggerResource swaggerResource(String name, String location, String version) { SwaggerResource swaggerResource = new SwaggerResource(); swaggerResource.setName(name); swaggerResource.setLocation(location); swaggerResource.setSwaggerVersion(version); return swaggerResource; } } 
   }

yml配置：

###註冊 中心
eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8100/eureka/
server:  ##api網關端口號
  port: 81
###網關名稱
spring:   ##網關服務名稱
  application:
    name: service-zuul
  ###網關名稱  
  cloud:
    config:
    ####讀取後綴
      profile: dev
      ####讀取config-server註冊地址
      discovery:
        service-id: confi
    
### 配置網關反向代理    
zuul:
  routes:
    api-member:  ##隨便寫的
     ### 以 /api-member/訪問轉發到會員服務   經過別名找
      path: /api-member/**
      serviceId: app-toov5-member  ##別名  若是集羣的話  默認整合了ribbon 實現輪訓 負載均衡
    api-order:   ##隨便寫的
        ### 以 /api-order/訪問轉發到訂單服務
      path: /api-order/**
      serviceId: app-toov5-order   ##別名

　　

 

 與yml的對應！

 

啓動 eureka  zuul member 而後訪問
