# 解决eureka注册中心集群模式defaultZone参数使用localhost+端口无效问题 #

*  ## 处理方案 ##
    
    1.  增加 eureka.server.my-url参数
        
            eureka:
              server:
                my-url: xxx
 *  ## 问题描述 ##
    
    1.  application.yml配置文件

 *  ## 问题排查 ##
    
    1.  通过yml文件进入defaultZone参数作用类为EurekaClientConfigBean类的serviceUrl变量  
        ![在这里插入图片描述][20191107132824507.png]
    2.  Alt+F7搜索使用该参数的地方  
        ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzI1MjE1ODIx_size_16_color_FFFFFF_t_70 2]
    3.  设置断点debug启动，getEurekaServerServiceUrls方法将集群节点以逗号进行分割组成list返回  
        ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzI1MjE1ODIx_size_16_color_FFFFFF_t_70 3]
    4.  调用链往前推，最终在PeerEurekaNodes类resolvePeerUrls方法上找到过滤节点的代码  
        ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzI1MjE1ODIx_size_16_color_FFFFFF_t_70 4]
    5.  循环调用isThisMyUrl方法进行过滤，方法较为简单，hostFromUrl方法获取主机名，可以看到，如果使用localhost作为defaultZone参数，则这里 hostName.equals(myInfoComparator) 参数比较就会返回true从而过滤全部以localhost配置的节点  
        ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzI1MjE1ODIx_size_16_color_FFFFFF_t_70 5]
    6.  综上问题已经确定，通过设置 myUrl 参数使 isThisMyUrl 方法返回 false 即可跳过下面的判断  
        ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzI1MjE1ODIx_size_16_color_FFFFFF_t_70 6]
    7.  myUrl 参数由eureka.server.myUrl提供  
        ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzI1MjE1ODIx_size_16_color_FFFFFF_t_70 7]
 *  ## 测试 ##
    
    1.  配置文件增加 my-url 参数
        
        ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzI1MjE1ODIx_size_16_color_FFFFFF_t_70 8]
    2.  启动日志
