如何从命令提示符启动调试模式的 apachetomcat 服务器？

我想为我的应用程序启动调试模式。但是我需要从命令提示符启动调试模式。有可能吗？程序会在公猫5.5到公猫6之间变化吗。？

First, Navigate to the TOMCAT-HOME/bin directory.

Then, Execute the following in the command-line:

catalina.bat jpda start

If the Tomcat server is running under Linux, just invoke the catalina.sh program

catalina.sh jpda start

It's the same for Tomcat 5.5 and Tomcat 6

On windows 
$ catalina.bat jpda start
On Linux/Unix 
$ catalina.sh jpda start

For windows first set variables:

set JPDA_ADDRESS=8000
set JPDA_TRANSPORT=dt_socket

to start server in debug mode:

%TOMCAT_HOME%/bin/catalina.bat jpda start

For unix first export variables:

export JPDA_ADDRESS=8000
export JPDA_TRANSPORT=dt_socket

and to start server in debug mode:

%TOMCAT_HOME%/bin/catalina.sh jpda start

  1. From your IDE, create a remote debug configuration, configure it for the default JPDA Tomcat port which is port 8000.

  2. From the command line:

    Linux:

    cd apache-tomcat/bin
export JPDA_SUSPEND=y
./catalina.sh jpda run

    Windows:

    cd apache-tomcat\bin
set JPDA_SUSPEND=y
catalina.bat jpda run

  3. Execute the remote debug configuration from your IDE, and Tomcat will start running and you are now able to set breakpoints in the IDE.

Note:

The JPDA_SUSPEND=y line is optional, it is useful if you want that Apache Tomcat doesn't start its execution until step 3 is completed, useful if you want to troubleshoot application initialization issues.

Inside catalina.bat set the port on which you wish to start the debugger

if not "%JPDA_ADDRESS%" == "" goto gotJpdaAddress
set JPDA_ADDRESS=9001

Then you can simply start the debugger with 

catalina.bat jpda

Now from Eclipse or IDEA select remote debugging and start start debugging by connecting to port 9001.

There are two ways to run tomcat in debug mode

  1. Using jdpa run

  2. Using JAVA_OPTS

First setup the environment. Then start the server using following commands.

export JPDA_ADDRESS=8000


export JPDA_TRANSPORT=dt_socket


%TOMCAT_HOME%/bin/catalina.sh jpda start


sudo catalina.sh jpda start

refer this article for more information this is clearly define it

A short answer is to add the following options when the JVM is started.

JAVA_OPTS=" $JAVA_OPTS -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=8080"

These instructions worked for me on apache-tomcat-8.5.20 on mac os 10.13.3 using jdk1.8.0_152:

$ cd /path/to/apache-tomcat-8.5.20/bin
$ export JPDA_ADDRESS="localhost:12321"
$ ./catalina.sh jpda run

Now connect to port 12321 from IntelliJ/Eclipse and enjoy remote debugging.

If you're wanting to do this via powershell on windows this worked for me

$env:JPDA_SUSPEND="y"

$env:JPDA_TRANSPORT="dt_socket"

/path/to/tomcat/bin/catalina.bat jpda start
