1. 配置tomcat服务器:修改tomcat的部署配置为:从不自动发布,禁用Web模块的自动从新装入为:禁用
2. 在tomcat运行配置上添加vm参数:-noverify -javaagent:D:\RUNTIME\jrebel\jrebel.jar -Dmyproject.root=D:/project/operamasks/workspaces/xxxx -Drebel.disable_update=true
其中:-javaagent的值表示jrebel的jar包路径
-Dmyproject.root的值表示当前的需要热部署的工程路径
3. 在工程的src源文件夹下添加名称为:rebel.xml的配置文件,内容格式如下:
<?xml version="1.0" encoding="UTF-8"?>
<application xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.zeroturnaround.com" xsi:schemaLocation="http://www.zeroturnaround.com http://www.zeroturnaround.com/alderaan/rebel-2_0.xsd">
<classpath>
<dir name="${myproject.root}/bin">
</dir>
<dir name="${myproject.root}/web/WebContent/WEB-INF/classes">
</dir>
</classpath>
<web>
<link target="/">
<dir name="${myproject.root}/web/WebContent">
</dir>
</link>
</web>
</application>
其中:myproject.root就是tomcat vm参数中指定的工程路径,你也可以使用绝对路径
这个文件定义的就是jrebel要监控的具体文件夹,即class文件和资源文件(比如:jsp等)
4.最后,启动tomcat服务器的成功提示:

=============================== [JRebel Spring Framework Plugin] ===============================
Plugins are contributed by third party and can cause compatibility problems.
If you have any troubles set -Drebel.spring_plugin=false to disable it.
------------------------------------------------------------------------------------------
Description: Supports adding new beans and adding new bean dependencies using
annotations or XML. Singletons will be reconfigured after the change. It also
supports adding or changing Spring MVC controllers or handlers.
=============================== [/JRebel Spring Framework Plugin] ==============================
=============================== [JRebel AspectJ Plugin DISABLED] ==============================
You can enable AspectJ Plugin by setting -Drebel.aspectj_plugin=true.
------------------------------------------------------------------------------------------
Description: Allows the AspectJ load-time weaving (javaagent launched by aj5 or
-javaagent:aspectjweaver.jar) to be used with JavaRebel. Note that AspectJ
weaver will still show "java.lang.Exception: AspectJ5 does not weave hotswapped
class" in the beginning, but this can be safely ignored.

到此为止,你成功配置jrebel了。

表示在运行期间jrebel会监控这些位置的class文件和资源文件的变化情况!!!!
以后就不需要经常启动tomcat来测试了,这种方便时可想而知的!
