当使用Oracle的JDBC驱动连接数据库时,会出现这种错误:access denied (javax.management.MBeanTrustPermission register)

    一般的解决办法是修改{JAVA_HOME}\jre\lib\security\java.policy文件,添加一行:

    permission javax.management.MBeanTrustPermission “register”

    但是这种方法很不方便,我经过实践,其实还有一种简便的方法,就是实现一个自己的Policy:

    源代码如下:

    1. Policy.setPolicy(new AWSPolicy()); // 启动方法里设置Policy
    3.   private static class AWSPolicy extends Policy {
    4.     private final Policy defaultPolicy;
    7.     public AWSPolicy() {
    8.       super();
    11.       defaultPolicy = Policy.getPolicy();
    12.     }
    15.     @Override
    16.     public boolean implies(ProtectionDomain domain, Permission permission) {
    17.       if (permission instanceof javax.management.MBeanTrustPermission) {
    18.         return true;
    19.       } else {
    20.         return defaultPolicy.implies(domain, permission);
    21.       }
    22.     }
    23.   }
