Question

我已经尝试过第一个Jetty，因为他们宣称它是从头开始设计的模块化设计但是在评论了“--module = jsp”中的行：

{jetty.home}/start.ini
{jetty.home}/demo-base/start.d/jsp.ini

正在加载大量JSP功能：

_STOP_PORT=65521
_STOP_KEY="stop_now_123"

java -jar ../start.jar STOP.PORT="${_STOP_PORT}" STOP.KEY="${_STOP_KEY}" --list-modules=jsp

 Available Modules:
 ==================
 tags: [jsp]

    22) websocket       ${jetty.base}/start.d/demo.ini

〜作为测试，我还启动了Jetty并在使用其JSP测试页时记录了所有已加载的类（即使JSP模块据说不被jetty的启动引擎使用）

_LOG_FL="jetty_startup_loaded_classes_$(date +%Y%m%d%H%M%S).log"

java  -d64 -server -verbose:class -jar ../start.jar STOP.PORT="${_STOP_PORT}" STOP.KEY="${_STOP_KEY}") > "${_LOG_FL}" 2>&1

$ cat "${_LOG_FL}" | grep jsp > "${_LOG_FL}"_jsp_classes_lines.log

$ ls -l "${_LOG_FL}"_jsp_classes_lines.log

$ wc -l "${_LOG_FL}"_jsp_classes_lines.log

$ cat "${_LOG_FL}"_jsp_classes_lines.log | grep "\[Loaded org.apache.jsp.jsp"

Answer 1

您还需要停用--module=jstl，这取决于jsp模块。

 Module: jstl  
       : Enables JSTL for all webapplications deployed on the server  
 Depend: jsp, apache-jstl

参考：Managing Startup Modules

Answer 2

根据Sierra和Erdfelt的建议，我确实删除了所有jsp和jslt模块的依赖关系，并将{jetty.home} / lib / apache-jsp移离{jetty.home}。一切似乎都运转良好，但当我试图停止码头时，我得到了：

$ time java -jar ../start.jar STOP.PORT="${_STOP_PORT}" STOP.KEY="${_STOP_KEY}" --stop
java.lang.NullPointerException
 at org.eclipse.jetty.start.Main.stop(Main.java:576)
 at org.eclipse.jetty.start.Main.stop(Main.java:519)
 at org.eclipse.jetty.start.Main.doStop(Main.java:507)
 at org.eclipse.jetty.start.Main.start(Main.java:402)
 at org.eclipse.jetty.start.Main.main(Main.java:77)

Usage: java -jar $JETTY_HOME/start.jar [options] [properties] [configs]
 java -jar $JETTY_HOME/start.jar --help  # for more information

real    2m8.334s
user    0m1.737s
sys 0m0.193s

〜我要做的就是检查org.eclipse.jetty.start.Main中的停止线和相应的启动线。我仍然想知道我的猴子方式如何影响一些内部依赖并重新实现没有JSP的cdi和jfx

有没有办法只使用Jetty（或Tomcat）的servlet引擎（删除所有JSP功能）？
