爲什麼@HystrixCommand是Spring注入的註解失敗？

Question

我服務的POM文件，該文件是Maven項目如下：

<?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" 
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

</build> 


</project> 

我的服務的部分源代碼如下：

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

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

我的問題是，當我輸入com.netflix.hystrix.contrib.javanica.annotation.HystrixCommand，它不被認可。任何人遇到同樣的問題？

請告訴我你是如何解決它的。

謝謝。

根據最新的POM文件，它已被棄用，支持spring-cloud-starter-netflix-hystrix。 STS並沒有幫助我添加導入，因此您可能需要手動添加：

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