我有一个用 openJDK (Amazon Correto 11) 和 openJFX 编写的应用程序。

当我在本地运行应用程序时 - 一切正常。但是当我从网络共享执行应用程序时出现异常：

我使用命令运行应用程序：

\\\some-network-share\app\jre\bin\javaw.exe -jar myapp.jar

因为在这个网络共享上，我复制了 Amazon Correto 11 JDK 文件和我用于应用程序的其他库。

我在另一个线程中运行 get request 并且该线程引发异常。

我怎样才能克服这个问题？

请帮忙。

我尝试了不同的库： 1. OkHttpClient 2. Java Unirest

但在两个相同的错误。


public class MyGetExecutor {


    public static void main(String[] args) {

        Thread getThread = new Thread( new Runnable() {

            @Override
            public void run() {

                try {
                    logMessage.add( "Before request" );
                    com.mashape.unirest.http.HttpResponse<String> response = Unirest.get("https://myappserver.domain.com/api/v1/users/1")
                    .header("User-Agent", "PostmanRuntime/7.17.1")
                    .header("Accept", "*/*")
                    .header("Cache-Control", "no-cache")
                    .header("Postman-Token", "abf4b45d-a2c5-4f53-b4e3-1fa29643d616,e59130fc-5ce0-4b70-af48-ab3808362e36")
                    .header("Host", "wf01.cdprojektred.com")
                    .header("Accept-Encoding", "gzip, deflate")
                    .header("Cookie", "JSESSIONID=2C71F035C2EDFF145FED5C03C4887EF1")
                    .header("Connection", "keep-alive")
                    .header("cache-control", "no-cache")
                    .asString();
                    logMessage.add( "After request" );
                } catch (Exception e) {
                    // TODO Auto-generated catch block
                    logMessage.add( "Exception in getThread: " + e.getMessage() );
                }


            }

        }, "Get-thread");
        getThread.setUncaughtExceptionHandler(
                new Thread.UncaughtExceptionHandler() {
                    @Override
                    public void uncaughtException(Thread t, Throwable e) {
                        logMessage.add( "Error in thread: " + e );
                        logMessage.add( "Details: " + e.getCause().getMessage() );
                    }
                }
            );
        getThread.start();

        while( getThread.isAlive() ) {

            try {
                Thread.sleep(1000);
                logMessage.add("Main thread sleeping...");
            } catch (Exception e) {
                logMessage.add("Exception in main thread...: " + e.getMessage());
            }



        }

    }
}

编辑 1我添加了额外的堆栈跟踪 - 请检查

线索是堆栈跟踪中的最后一个原因：
Caused by: java.lang.SecurityException: Can't read cryptographic policy directory: unlimited

进入兔子洞：

  • java.security.properties通过从正在运行的 JVM中检查来验证您的安全策略来自何处 ：

    System.getProperty("java.security.properties");

    它应该存在并指向一个文件。检查该文件并确保它具有以下属性，并且可以从策略文件所在的位置获得crypto.policy=unlimited名为unlimited的文件夹。策略文件本身应说明在何处查找此文件夹。

    对于科雷托来说<jre_home>/conf/security/policy/

  • 您可以通过启动 JVM 并将策略文件的位置传递给它来修改安全策略的位置：
    java -Djava.security.properties==/conf/security/java.security
    或者
    java -Djava.security.properties=/conf/security/java.security

    =第一种情况下的附加符号将导致 Java 仅使用您指向的文件中的属性。
    第二个选项将添加/更新文件中定义的属性。

  • 最后，您必须在Correto 11周围挖掘才能找到策略文件。
