修改应用实例元数据

PUT http://localhost:8761/eureka/apps/SERVICES2/services2:7f411a785a97590bf4ae5176489e3d15/metadata?version=1.1.1

version 就为一个元数据。
修改后：

<application>
    <name>SERVICES2</name>
    <instance>
        <instanceId>services2:7f411a785a97590bf4ae5176489e3d15</instanceId>

        </leaseInfo>
        <metadata>
            <zone>primary</zone>
            <profile>dev</profile>
            <!--元数据version改成了1.1.1-->
            <version>1.1.1</version>
    
        </metadata>
        <homePageUrl>http://192.168.1.7:8082/</homePageUrl>

源码实现

eureka server 用到了jersey实现api功能，其中包含了子资源路由api功能。具体可以参考 https://blog.csdn.net/qq_30062125/article/details/83758334
