What are Java command line options to set to allow JVM to be remotely debugged?
提问by paulgreg
I know there's some JAVA_OPTSto set to remotely debug a Java program.
我知道有一些JAVA_OPTS设置可以远程调试 Java 程序。
What are they and what do they mean ?
它们是什么，它们是什么意思？

I have this articlebookmarked on setting this up for Java 5 and below.
我将这篇文章加入了书签，用于为 Java 5 及更低版本进行设置。
Basically run it with:
基本上运行它：
-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=1044
For Java 5 and above, run it with:
对于Java 5 及更高版本，运行它：
-agentlib:jdwp=transport=dt_socket,server=y,suspend=y,address=1044

Before Java 5.0, use -Xdebugand -Xrunjdwparguments. These options will still work in later versions, but it will run in interpreted mode instead of JIT, which will be slower.
在 Java 5.0 之前，使用-Xdebug和-Xrunjdwp参数。这些选项在以后的版本中仍然有效，但它将在解释模式下运行，而不是在 JIT 下运行，后者会更慢。
From Java 5.0, it is better to use the -agentlib:jdwpsingle option:
从 Java 5.0 开始，最好使用-agentlib:jdwp单个选项：
-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=1044
Options on -Xrunjdwpor agentlib:jdwparguments are :
-Xrunjdwp或agentlib:jdwp参数的选项是：
transport=dt_socket: means the way used to connect to JVM (socket is a good choice, it can be used to debug a distant computer)address=8000: TCP/IP port exposed, to connect from the debugger,suspend=y: if 'y', tell the JVM to wait until debugger is attached to begin execution, otherwise (if 'n'), starts execution right away.
transport=dt_socket: 表示用于连接JVM的方式（socket是一个不错的选择，可以用来调试远程计算机）address=8000: TCP/IP 端口暴露，从调试器连接，suspend=y：如果'y'，告诉JVM等待直到调试器被附加开始执行，否则（如果'n'），立即开始执行。

For java 1.5 or greater:
对于 java 1.5 或更高版本：
java -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=5005 <YourAppName>
For java 1.4:
对于 Java 1.4：
java -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5005 <YourAppName>
For java 1.3:
对于 Java 1.3：
java -Xnoagent -Djava.compiler=NONE -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5005 <YourAppName>
Here is output from a simple program:
这是一个简单程序的输出：
java -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=1044 HelloWhirled
Listening for transport dt_socket at address: 1044
Hello whirled

Here is the easiest solution.
这是最简单的解决方案。
There are a lot of environment special configurations needed if you are using Maven. So, if you start your program from maven, just run the mvnDebugcommand instead of mvn, it will take care of starting your app with remote debugging configurated. Now you can just attach a debugger on port 8000.
如果您使用 Maven，则需要很多环境特殊配置。因此，如果您从 maven 启动您的程序，只需运行mvnDebug命令而不是mvn，它将负责启动您的应用程序并配置远程调试。现在您只需在端口 8000 上附加调试器即可。
It'll take care of all the environment problems for you.
它会为您解决所有环境问题。

Since Java 9.0 JDWP supports only local connections by default. http://www.oracle.com/technetwork/java/javase/9-notes-3745703.html#JDK-8041435
由于 Java 9.0 JDWP 默认只支持本地连接。 http://www.oracle.com/technetwork/java/javase/9-notes-3745703.html#JDK-8041435
For remote debugging one should run program with *:in address:
对于远程调试，应该使用*:地址运行程序：
-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=*:8000

-agentlib:jdwp=transport=dt_socket,server=y,suspend=y,address=PORT_NUMBER
Here we just use a Socket Attaching Connector, which is enabled by default when the dt_socket transport is configured and the VM is running in the server debugging mode.
这里我们只使用了 Socket Attaching Connector，当配置了 dt_socket 传输并且 VM 在服务器调试模式下运行时，它默认启用。
