1、自定义java.policy配置(如何让你的类禁止读写文件？禁止创建Socket对象？) - CSDN博客
一、java.security错误样例
完整的log如下

重点是下面这句话的提示：
Caused by: java.security.AccessControlException: access denied ("java.util.PropertyPermission" "*" "read,write")
这一句说明是java的安全管理机制限制了程序的读写操作，出现类似这个错误可以新建一个在项目中间一个文件名为policy的文件夹，创建文件my.policy，复制下面的代码，粘贴进去。
grant {
permission java.util.PropertyPermission "*", "read,write";
};然后在VM参数中写入下面这句话，制定程序的policy文件
-Djava.security.policy=policy/my.policy
运行即可。
二、类似错误
先贴出我的policy文件以及测试类的运行参数截图
如果还报类似错误，进行相应处理。下面给出我遇到的错误，以及policy文件中对应的授权。

对应my.policy文件
grant {
permission javax.management.MBeanTrustPermission "register";
permission javax.management.MBeanServerPermission "createMBeanServer";
// 表示文件名的时候要用双反斜杠，用-表示该文件夹下所有子目录
permission java.io.FilePermission "Capabilities.props", "read";
permission java.io.FilePermission "C:\\Users\\xiaochenchen\\-", "read,write";
permission java.util.PropertyPermission "*", "read,write";
permission java.net.NetPermission "getProxySelector";
permission java.net.NetPermission "setDefaultAuthenticator";
permission java.lang.RuntimePermission "getClassLoader";
permission java.lang.RuntimePermission "accessDeclaredMembers";
};
PS：
VM参数的等号后面是文件在项目中的相对路径，也可以用绝对路径
-Djava.security.policy=E:\elasticsearch-5.4.1(1)\elasticsearch-5.4.1\core\src\main\resources\config\elasticsearch.policy
附上es源码运行参数
-Des.path.home=E:\elasticsearch-5.4.1(1)\elasticsearch-5.4.1\core\src\main -Djava.security.policy=E:\elasticsearch-5.4.1(1)\elasticsearch-5.4.1\core\src\main\resources\config\elasticsearch.policy -Xms4g -Xmx4g
