运行Java程序时报错Error:(3001, 19) java: ncCommonSvc.AsyncClient.microprobe_call不是抽象的
运行Java程序时报错Error:(3001, 19) java: ncCommonSvc.AsyncClient.microprobe_call不是抽象的, 并且未覆盖org.apache.thrift.async.TAsyncMethodCall中的抽象方法getResult();Error:(3013, 19) java: ncCommonSvc.AsyncClient.microprobe_call中的getResult()无法覆盖org.apache.thrift.async.TAsyncMethodCall中的getResult()返回类型void与java.lang.Object不兼容 报这个错误可能是什么原因呢,代码是由C++转成java测试thrift接口的,所以应该不是代码本身的问题,是代码里面实现的方法与引入的thrift库有冲突么 没有接触过Java的小白求教,要用Jmeter工具才用Java的
SpringCloud项目中用jmeter测试feign负载 异常率比直接访问client生产者还高
初入SpringCloud坑的小白 把SpringCloud负载均衡作为毕设课题研究 能不能有个大佬帮我分析一下问题 三台服务器 学生云 1核2G 带宽1M 五个项目 Eureka,fegin消费者,clientA,clientB,clientC三个生产者 **服务器1:Eureka,feign ,clinetA 服务器2:clientB 服务器3:clientC** 使用jmeter测试500线程/S 持续3秒 共计1500线程 访问feign和clientA **测试1访问feign**:异常率在33%左右 **测试2访问clientA**:异常率在28-33%左右 异常的基本上都是连接超时failed: Connection timed out: connect 在服务器1上抓包查看请求发现有的请求报了一些错 ``` 2019-05-12

Java学习的正确打开方式
在博主认为,对于入门级学习java的最佳学习方法莫过于视频+博客+书籍+总结,前三者博主将淋漓尽致地挥毫于这篇博客文章中,至于总结在于个人,实际上越到后面你会发现学习的最好方式就是阅读参考官方文档其次就是国内的书籍,博客次之,这又是一个层次了,这里暂时不提后面再谈。博主将为各位入门java保驾护航,各位只管冲鸭!!!上天是公平的,只要不辜负时间,时间自然不会辜负你。 何谓学习?博主所理解的学习,它

程序员接私活怎样防止做完了不给钱?
