1. 配置tomcat伺服器：修改tomcat的部署配置為：從不自動釋出，禁用Web模組的自動從新裝入為：禁用

2. 在tomcat執行配置上新增vm引數：-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包路徑
   -Dmyproject.root的值表示當前的需要熱部署的工程路徑

3. 在工程的src原始檔夾下新增名稱為：rebel.xml的配置檔案，內容格式如下：

1. <?xml version="1.0" encoding="UTF-8"?>  
2. <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">  
3.     <classpath>  
4.         <
   dir name="${myproject.root}/bin">  
5.         </dir>  
6.         <dir name="${myproject.root}/web/WebContent/WEB-INF/classes">  
7.         </dir>  
8.     </classpath>  
9.     <web>  
10.         <link target="/">  
11.             <dir name="${myproject.root}/web/WebContent">  
12.             </
    dir>  
13.         </link>  
14.     </web>  
15. </application>  

其中：myproject.root就是tomcat vm引數中指定的工程路徑，你也可以使用絕對路徑
這個檔案定義的就是jrebel要監控的具體資料夾，即class檔案和資原始檔（比如：jsp等）

4.最後，啟動tomcat伺服器的成功提示：

=============================== [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.
