Question

我的服务的pom文件是maven项目如下：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

我服务的部分源代码如下：

@HystrixCommand(fallbackMethod = "reliable")
public String readingList(){
    URI uri = URI.create("http://localhost:8090/recommended");

    return this.restTemplate.getForObject(uri, String.class);
}

我的问题是，当我导入com.netflix.hystrix.contrib.javanica.annotation.HystrixCommand时，无法识别。有人遇到过同样的问题吗？

请告诉我你是如何解决的。

感谢。

Answer 1

根据最新的POM文件，它已被弃用，而不是spring-cloud-starter-netflix-hystrix。 STS也没有帮助我添加导入，因此您可能需要手动添加它：

import com.netflix.hystrix.contrib.javanica.annotation.HystrixCommand;

为什么@HystrixCommand是注入弹簧的注释失败了？
