tomcat+myeclipse配置遠程調試

做爲一名開發人員多多少少會遇到各類問題，在衆多問題中或許你也會遇到：在本地都運行的好好的，但是發佈到服務器後怎麼就出問題了呢？出現這種問題的緣由有不少種，可究竟是什麼緣由引發的呢？咱們開發過程當中一般都是經過myeclipse的debug來查找緣由，總不可能在服務器上安裝myeclipse來調試程序吧？那怎麼辦？不要緊，還好有jpda（全稱Java^TM Platform Debugger Architecture）這個東東，須要在tomcat的啓動文件（startup.bat）中配置jpda，爲了避免修改原有的文件，咱們新增一個startup_debug.bat，內容以下：

if not "%CATALINA_HOME%" == "" goto gotHome
set "CATALINA_HOME=%CURRENT_DIR%"

echo The CATALINA_HOME environment variable is not defined correctly
echo This environment variable is needed to run this program
goto end
:okHome

set "EXECUTABLE=%CATALINA_HOME%\bin\catalina.bat"

rem Check that target executable exists
if exist "%EXECUTABLE%" goto okExec
echo Cannot find "%EXECUTABLE%"
echo This file is needed to run this program
goto end
:okExec

:doneSetArgs

set JPDA_TRANSPORT=dt_socket
set JPDA_ADDRESS=8000
set JPDA_SUSPEND=n

call "%EXECUTABLE%" jpda start %CMD_LINE_ARGS%

:end

內容與startup.bat幾乎一致，標黑的腳本爲新增的腳本，啓動時啓動startup_debug.bat便可

參數解釋：

jpda_transport=dt_socket（JPDA front-end和back-end之間的傳輸方法。dt_socket表示使用套接字傳輸。）

jpad_address=8000（JVM在8000端口上監聽請求。）

jpda_suspend=n（n表示直接啓動監聽端口和JVM，y表示啓動的JVM會暫停等待，直到調試器鏈接上。）

 

配置本地的myeclipse

 右鍵須要調試的工程→debug as→debug configurations，new 一個java remote application，填寫以下圖，信息填寫正確後，點擊debug便可進行遠程調試了。

 

 

 注意：一、調試時須要保持本地代碼和服務器上代碼一致

          二、確認防火牆關閉
