Feign挡板和Mock
背景:
在项目开发中,会有调用第三方接口的场景。当开发时,对方不愿意提供测试服务器给我们调用,或者有的接口会按调用次数进行计费。当联调时,第三方的测试服务器也可能会出现不稳定,如果他们的服务挂了,我们就一直等着服务恢复,那么这就相当影响效率了。如果我们在开发时,就定义一个挡板或者mock服务,在发起调用时,不直接调到第三方接口,而是调到我们自己的挡板代码或者mock服务,这样就可以避免这些问题了。
优势:
- 挡板代码,不需要侵入业务代码,可以根据入参做一些动态结果返回
- 不需要专门开发一个挡板服务,并且在每次启动客户端都先启动挡板服务
- 可以自由选择使用挡板还是Mock数据
Demo详细代码,已经提交到Github,欢迎star
Demo地址: https://github.com/Seifon/FeignStubMock
一、下面我就以一个第三方SMS短信接口来做演示:
首先,我们写一个Feign客户端接口,正常调用第三方接口:
1.定义一个SMS短信的Feign客户端接口:
import cn.seifon.example.feignstubmock.dto.YunxunSmsReqDto;
import cn.seifon.example.feignstubmock.dto.YunxunSmsRespDto;
import org.springframework.cloud.openfeign.FeignClient;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
/**
* @Author: Seifon
* @Description:
* @Date: Created in 10:24 2019/1/7
*/
@FeignClient(name = "smsclient", url = "${sms.url}", primary = false)
public interface YunxunSmsFeign {
/**
*
* @param request
* @return {"code":"0","failNum":"0","successNum":"1","msgId":"19012516213625881","time":"20190125162136","errorMsg":""}
* @return {"code":"107","msgId":"","time":"20190125162358","errorMsg":"手机号码格式错误"}
*/
@PostMapping("/msg/variable/json")
YunxunSmsRespDto send(@RequestBody YunxunSmsReqDto request);
}
注意:@FeignClient注解里面的primary属性一定要设置为false,这是为了防止在开启Feign挡板时,出现多个Feign客户端导致启动报错。
2.写一个单元测试:
import cn.seifon.example.feignstubmock.dto.YunxunSmsReqDto;
import cn.seifon.example.feignstubmock.dto.YunxunSmsRespDto;
import cn.seifon.example.feignstubmock.feign.YunxunSmsFeign;
import com.alibaba.fastjson.JSON;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
@RunWith(SpringRunner.class)
@SpringBootTest
public class FeignStubMockApplicationTests {
@Autowired
private YunxunSmsFeign yunxunSmsFeign;
@Test
public void feignStubMockTest() {
YunxunSmsReqDto yunxunSmsReqDto=new YunxunSmsReqDto();
yunxunSmsReqDto.setAccount("XXXXXXX");
yunxunSmsReqDto.setPassword("XXXXXXX");
yunxunSmsReqDto.setMsg("登录验证码:{$var},请不要对非本人透露。");
yunxunSmsReqDto.setParams("13011112222,123456");
yunxunSmsReqDto.setReport("true");
YunxunSmsRespDto send = yunxunSmsFeign.send(yunxunSmsReqDto);
//打印结果
System.out.println(JSON.toJSON(send));
}
}
3.1.我们输入一个正确的手机号,拿一个成功的结果:

此时,我们可以根据日志,看到请求的地址也是第三方的url
3.2.我们输入一个错误的手机号,拿一个失败的结果:

当我们知道了两种情况下出现的结果,那么我们就可以模拟响应结果啦。小技巧:我们可以先跟对方调接口,把各种响应报文保存下来,方便后面直接mock数据
二、接下来进入挡板编写环节:
1.编写一个YunxunSmsFeignStub类,并实现YunxunSmsFeign接口:
import cn.seifon.example.feignstubmock.dto.YunxunSmsReqDto;
import cn.seifon.example.feignstubmock.dto.YunxunSmsRespDto;
import cn.seifon.example.feignstubmock.feign.YunxunSmsFeign;
import org.apache.commons.lang3.RandomUtils;
import org.apache.commons.lang3.StringUtils;
import org.apache.commons.lang3.time.DateFormatUtils;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.autoconfigure.condition.ConditionalOnProperty;
import org.springframework.context.annotation.Primary;
import org.springframework.stereotype.Component;
import java.util.Date;
/**
* @Author: Seifon
* @Description:
* @Date: Created in 10:24 2019/1/7
*/
@Primary //注意:需要在原Feign接口@FeignClient注解加入primary = false 属性
@Component
@ConditionalOnProperty(name = "feign-stub.yunxun.sms.mode", havingValue = "stub")
public class YunxunSmsFeignStub implements YunxunSmsFeign {
private static final Logger LOG = LoggerFactory.getLogger(YunxunSmsFeignStub.class);
@Override
public YunxunSmsRespDto send(YunxunSmsReqDto request) {
YunxunSmsRespDto yunxunSmsRespDto = new YunxunSmsRespDto();
//模拟正常响应结果
yunxunSmsRespDto.setCode("0");
yunxunSmsRespDto.setFailNum("0");
yunxunSmsRespDto.setSuccessNum("1");
yunxunSmsRespDto.setMsgId(String.valueOf(RandomUtils.nextLong(19000000000000000L, 19999999999999999L)));
yunxunSmsRespDto.setTime(DateFormatUtils.format(new Date(), "yyyyMMddHHmmss"));
yunxunSmsRespDto.setErrorMsg("");
String params = request.getParams();
String[] paramSplit = StringUtils.split(params, ",");
if (paramSplit[0].length() != 11) {
//模拟错误响应结果
yunxunSmsRespDto.setCode("107");
yunxunSmsRespDto.setMsgId("");
yunxunSmsRespDto.setErrorMsg("手机号码格式错误");
}
return yunxunSmsRespDto;
}
}
注意:必须标注@Primary注解,否则启动会报错。@ConditionalOnProperty的作用就是根据application.yaml配置的相关属性,判断是否注入Spring容器
2.application.yaml文件,加入下面的配置:
sms:
url: 'http://smssh1.253.com'
#yunxun:代表第三方系统名称,sms:代表业务名称,mode:代表Stub模式,url:代表mock服务地址
feign-stub:
yunxun:
sms:
mode: 'stub'
3.为了区分返回的内容是挡板结果,我们可以写一个AOP切面打印日志:
import com.alibaba.fastjson.JSON;
import org.apache.commons.lang3.StringUtils;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Pointcut;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;
/**
* @Author: Seifon
* @Description:
* @Date: Created in 10:24 2019/1/7
*/
@Aspect
@Component
public class FeignStubAspect {
private static final Logger LOG = LoggerFactory.getLogger(FeignStubAspect.class);
@Pointcut("execution(* cn.seifon.example.feignstubmock..stub.*.*(..))")
public void pointCut(){}
@Around("pointCut()")
public Object around(ProceedingJoinPoint pjp){
String name = StringUtils.join(pjp.getTarget().getClass().getName(), ".", pjp.getSignature().getName());
LOG.info("-----【{}】---- 进入挡板模式... request: 【{}】", name, JSON.toJSON(pjp.getArgs()));
try {
Object proceed = pjp.proceed();
LOG.info("-----【{}】---- 退出挡板模式... request: 【{}】, response: 【{}】", name, JSON.toJSON(pjp.getArgs()), JSON.toJSON(proceed));
return proceed;
} catch (Throwable e) {
e.printStackTrace();
}
return null;
}
}
4.1.运行之前写的单元测试代码(输入一个正确的手机号):
2019-01-28 11:32:51.255 INFO 7488 --- [ main] c.s.e.f.aspect.FeignStubAspect : -----【cn.seifon.example.feignstubmock.feign.stub.YunxunSmsFeignStub.send】---- 进入挡板模式... request: 【[{"msg":"登录验证码:{$var},请不要对非本人透露。","password":"XXXXXXX","report":"true","params":"13011112222,123456","account":"XXXXXXX"}]】
2019-01-28 11:32:51.975 INFO 7488 --- [ main] c.s.e.f.aspect.FeignStubAspect : -----【cn.seifon.example.feignstubmock.feign.stub.YunxunSmsFeignStub.send】---- 退出挡板模式... request: 【[{"msg":"登录验证码:{$var},请不要对非本人透露。","password":"XXXXXXX","report":"true","params":"13011112222,123456","account":"XXXXXXX"}]】, response: 【{"code":"0","failNum":"0","successNum":"1","msgId":"19148964234899564","time":"20190128113251","errorMsg":""}】
{"code":"0","failNum":"0","successNum":"1","msgId":"19148964234899564","time":"20190128113251","errorMsg":""}
4.2.运行之前写的单元测试代码(输入一个错误的手机号):
2019-01-28 11:35:27.177 INFO 15204 --- [ main] c.s.e.f.aspect.FeignStubAspect : -----【cn.seifon.example.feignstubmock.feign.stub.YunxunSmsFeignStub.send】---- 进入挡板模式... request: 【[{"msg":"登录验证码:{$var},请不要对非本人透露。","password":"XXXXXXX","report":"true","params":"130,123456","account":"XXXXXXX"}]】
2019-01-28 11:35:27.900 INFO 15204 --- [ main] c.s.e.f.aspect.FeignStubAspect : -----【cn.seifon.example.feignstubmock.feign.stub.YunxunSmsFeignStub.send】---- 退出挡板模式... request: 【[{"msg":"登录验证码:{$var},请不要对非本人透露。","password":"XXXXXXX","report":"true","params":"130,123456","account":"XXXXXXX"}]】, response: 【{"code":"107","failNum":"0","successNum":"1","msgId":"","time":"20190128113527","errorMsg":"手机号码格式错误"}】
{"code":"107","failNum":"0","successNum":"1","msgId":"","time":"20190128113527","errorMsg":"手机号码格式错误"}
以上代码就完成了一个stub挡板功能,可有时候,我们已经拿到第三方接口的返回报文,并切不想去写一大段Stub代码。那么这个时候,我们就可以选择下面的Mock方式去完成我们的功能。
三、接下来进入Mock环节:
1. 首先准备一个mock服务,这里我就用自己比较喜欢的一个mock工具(mock-json-server)给大家演示:
1.1 安装nodejs:
参看官网:http://nodejs.cn/
1.2 安装mock-json-server:
npm install -g mock-json-server
1.3 新建mock数据文件(命名为:data.json):
{
"/msg/variable/json": {
"post": {
"code":"0",
"failNum":"0",
"successNum":"1",
"msgId":"19012516213625881",
"time":"20190125162136",
"errorMsg":""
}
}
}
1.4 运行:
mock-json-server {path}/data.json --port=1240
{path}替换为存放data.json的绝对路径
1.5 如果显示如下结果,就代表mock服务运行成功:
JSON Server running at http://localhost:1240/
mock-json-server具体使用文档,请参考:https://www.npmjs.com/package/mock-json-server
2. 准备工作做好后,接下来,就进入Mock正式环节:
2.1 首先,我们定义一个YunxunSmsFeignMock接口,并且继承YunxunSmsFeign接口
import cn.seifon.example.feignstubmock.feign.YunxunSmsFeign;
import org.springframework.boot.autoconfigure.condition.ConditionalOnProperty;
import org.springframework.cloud.openfeign.FeignClient;
import org.springframework.context.annotation.Primary;
import org.springframework.stereotype.Component;
/**
* @Author: Seifon
* @Description:
* @Date: Created in 10:24 2019/1/7
*/
@Primary //注意:需要在原Feign接口@FeignClient注解加入primary = false 属性
@Component
@ConditionalOnProperty(name = "feign-stub.yunxun.sms.mode", havingValue = "mock")
@FeignClient(name = "smsclient-mock", url = "${feign-stub.yunxun.sms.mockUrl}" ,path = "/")
public interface YunxunSmsFeignMock extends YunxunSmsFeign {
}
注意:必须标注@Primary注解,否则启动时会报错。@FeignClient里的name属性不能跟原Feign接口名称相同,如果相同会启动报错。@ConditionalOnProperty的作用就是根据application.yaml配置的相关属性,判断是否注入Spring容器
2.2 application.yaml文件,加入下面的配置:
sms:
url: 'http://smssh1.253.com'
#生产环境请勿添加此配置。mode说明:''-不开启, 'mock'-mock模式, 'stub'-stub模式。url说明:只有mock模式需要配置调试url。fund为第三方机构,repayment是业务名称
#yunxun:代表第三方系统名称,sms:代表业务名称,mode:代表挡板模式,url:代表mock服务地址
feign-stub:
yunxun:
sms:
mode: 'mock'
mockUrl: "http://localhost:1240"
2.3 为了区分返回的内容是Mock结果,我们可以写一个AOP切面打印日志:
import com.alibaba.fastjson.JSON;
import org.apache.commons.lang3.StringUtils;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Pointcut;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;
/**
* @Author: Seifon
* @Description:
* @Date: Created in 10:24 2019/1/7
*/
@Aspect
@Component
public class FeignMockAspect {
private static final Logger LOG = LoggerFactory.getLogger(FeignMockAspect.class);
@Pointcut("execution(* cn.seifon.example.feignstubmock..mock.*.*(..))")
public void pointCut(){}
@Around("pointCut()")
public Object around(ProceedingJoinPoint pjp){
String name = StringUtils.join(pjp.getTarget().getClass().getName(), ".", pjp.getSignature().getName());
LOG.info("-----【{}】---- 进入Mock模式... request: 【{}】", name, JSON.toJSON(pjp.getArgs()));
try {
Object proceed = pjp.proceed();
LOG.info("-----【{}】---- 退出Mock模式... request: 【{}】, response: 【{}】", name, JSON.toJSON(pjp.getArgs()), JSON.toJSON(proceed));
return proceed;
} catch (Throwable e) {
e.printStackTrace();
}
return null;
}
}
2.4 运行之前的单元测试类,得到如下结果:

说明:此时我们根据日志,会发现feign调用的url已经变为我们的Mock服务地址了。同理,如果要返回失败结果,只需要修改data.json文件,再次调用后,即可得到我们想要的结果了。
四、结语:
如果有什么需要改进的地方,或者不正确的地方,请在评论里面提出并指正。谢谢!
