任何有使用Java-Sandbox经验的人,我已经实现了文档中的一个基本示例,但我无法让它工作。
代码:SandPlayground.java
import java.util.concurrent.TimeUnit;
import net.datenwerke.sandbox.*;
import net.datenwerke.sandbox.SandboxContext.AccessType;
import net.datenwerke.sandbox.SandboxContext.RuntimeMode;
import net.datenwerke.sandbox.SandboxedEnvironment;
public class SandPlayground {
/**
* @param args
*/
public static void main(String[] args) {
System.out.println("Running...");
SandboxService sandboxService = SandboxServiceImpl.initLocalSandboxService();
// configure context
SandboxContext context = new SandboxContext();
//context.setRunRemote(true);
context.setRunInThread(true);
context.setMaximumRunTime(2, TimeUnit.SECONDS, RuntimeMode.ABSOLUTE_TIME);
context.addClassPermission(AccessType.PERMIT, "java.lang.System");
context.addClassPermission(AccessType.PERMIT, "java.io.PrintStream");
//run code in sandbox
SandboxedCallResult<String> result = sandboxService.runSandboxed(MyEnvironment.class, context, "This is some value");
// output result
System.out.println(result.get());
}
}
我的环境.java
import net.datenwerke.sandbox.SandboxedEnvironment;
public class MyEnvironment implements SandboxedEnvironment<String> {
private final String myValue;
public MyEnvironment(String myValue){
this.myValue = myValue;
}
@Override
public String execute() throws Exception {
/* run untrusted code */
System.out.println(myValue);
/* return some value */
return "This is a different value";
}
}
我得到了错误:
编辑:我已经包含了依赖项,但我仍然遇到一些错误:
使用上面的代码,我得到:
Exception in thread "main" net.datenwerke.sandbox.exception.SandboxedTaskKilledException: killed task as maxmimum runtime was exceeded
at net.datenwerke.sandbox.SandboxMonitorDaemon.testRuntime(SandboxMonitorDaemon.java:82)
at net.datenwerke.sandbox.SandboxMonitorDaemon.run(SandboxMonitorDaemon.java:57)
at java.lang.Thread.run(Thread.java:724)
当我删除 context.setMaximumRunTime() 调用时,我得到:
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/collections/map/IdentityMap ...
任何帮助深表感谢。
