本文主要介绍如何编写一个hystrix的demo程序。

主要参考：

[https://github.com/Netflix/Hystrix/wiki/How-To-Use\#Hello-World][https_github.com_Netflix_Hystrix_wiki_How-To-Use_Hello-World]

1、引入maven依赖

<dependency>
                <groupId>com.netflix.hystrix</groupId>
                <artifactId>hystrix-core</artifactId>
                <version>1.5.12</version>
            </dependency>

2、编写一个集成HystrixCommand的类

package com.xueyou.hystrixdemo.v1;
    
    import com.netflix.hystrix.HystrixCommand;
    import com.netflix.hystrix.HystrixCommandGroupKey;
    
    public class CommandHelloworld extends HystrixCommand<String> {
        private String name;
    
        public CommandHelloworld(HystrixCommandGroupKey group, String name) {
            super(group);
            this.name = name;
        }
    
        @Override
        protected String run() throws Exception {
            return "hello " + name;
        }
    
    }

3、编写一个测试类进行测试

package com.xueyou.hystrixdemo.v1;
    
    import com.netflix.hystrix.HystrixCommandGroupKey;
    
    public class HelloWorld {
        public static void main(String[] args) {
            System.out.println(123);
            String result = new CommandHelloworld(HystrixCommandGroupKey.Factory.asKey("ExampleGroup"), "aaabbbccc").execute();
            String result2 = new CommandHelloworld(HystrixCommandGroupKey.Factory.asKey("ExampleGroup2"), "123sss").execute();
            System.out.println(result);
            System.out.println(result2);
        }
    }

4、运行结果：
