Elasticsearch 自定义分词插件报错 java.net.SocketPermission

矫情吗；* 2022-05-12 13:28 118阅读 0赞

在制作elasticsearch插件的时候已经申请了网络访问权限在`plugin-security.policy`里面

grant {
      // needed because of the hot reload functionality
      permission java.net.SocketPermission "*", "connect,resolve";
    };

而且在安装的是确实也授权了

但是一旦访问网络还是报错了

access denied (“java.net.SocketPermission” “具体的网络地址” “connect,resolve”)

最终的解决方案是修改jre的`java.policy`

在授权的最下面添加

permission java.net.SocketPermission "*", "connect,resolve";

![在这里插入图片描述][70 2]

重启elasticsearch就可以了

其实在编写插件的过程中有可能遇到很多权限的问题，终极解决方案，修改jre的`java.policy`  
路径为`jdk安装目录\jre\lib\security\java.policy`

加上这么一行

permission java.security.AllPermission;
