在Java Spring应用程序中处理内容提供程序故障的最佳方法

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-netflix-hystrix</artifactId>
</dependency>

public class ContentProviderCommand extends HystrixCommand<String> {
    private final String contentProviderUrl;

    public ContentProviderCommand(String contentProviderUrl) {
        super(HystrixCommandGroupKey.Factory.asKey("ContentProviderGroup"));
        this.contentProviderUrl = contentProviderUrl;
    }

    @Override
    protected String run() throws Exception {
        // 执行内容提供程序调用的逻辑
        // 返回内容提供程序的响应
    }

    @Override
    protected String getFallback() {
        // 备用逻辑，处理故障时的情况
        // 返回备用的响应
    }
}

String contentProviderUrl = "http://example.com/content";
ContentProviderCommand command = new ContentProviderCommand(contentProviderUrl);
String response = command.execute();
