首先安装nexus做为maven的私服：

maven+snoatype nexus+jrebel+eclipse+tomcat整合的小例子

点击install-nexus安装nexus为服务后，访问：http://localhost:8081/nexus/

点击后上角的log in输入默认用户名和密码：admin/admin123，然后点击左侧的菜单repositories,依次单击将右面显示的三个type为proxy的configure中的Download Remote Indexes设置为true;

这么做的目的是同步下载远程索引到本地，以便本地快速搜索。点击保存后依次右键这3个仓库将其repair index。以便更新本地索引。

2，配置maven，关于maven环境变量的设置就不说了。网上有的是。

  <!-- mirrors
 
   | This is a list of mirrors to be used in downloading artifacts from remote repositories.
 
   |
 
   | It works like this: a POM may declare a repository to use in resolving certain artifacts.
 
   | However, this repository may have problems with heavy traffic at times, so people have mirrored
 
   | it to several places.
 
   |
 
   | That repository definition will have a unique id, so we can create a mirror reference for that
 
   | repository, to be used as an alternate download site. The mirror site will be the preferred
 
   | server for that repository.
 
   |-->
 
  <mirrors>
 
    <!-- mirror
 
     | Specifies a repository mirror site to use instead of a given repository. The repository that
 
     | this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used
 
     | for inheritance and direct lookup purposes, and must be unique across the set of mirrors.
 
     |

  <!-- profiles
 
   | This is a list of profiles which can be activated in a variety of ways, and which can modify
 
   | the build process. Profiles provided in the settings.xml are intended to provide local machine-
 
   | specific paths and repository locations which allow the build to work in the local environment.
 
   |
 
   | For example, if you have an integration testing plugin - like cactus - that needs to know where
 
   | your Tomcat instance is installed, you can provide a variable here such that the variable is
 
   | dereferenced during the build process to configure the cactus plugin.
 
   |
 
   | As noted above, profiles can be activated in a variety of ways. One way - the activeProfiles
 
   | section of this document (settings.xml) - will be discussed later. Another way essentially
 
   | relies on the detection of a system property, either matching a particular value for the property,
 
   | or merely testing its existence. Profiles can also be activated by JDK version prefix, where a
 
   | value of '1.4' might activate a profile when the build is executed on a JDK version of '1.4.2_07'.
 
   | Finally, the list of active profiles can be specified directly from the command line.
 
   |
 
   | NOTE: For profiles defined in the settings.xml, you are restricted to specifying only artifact
 
   |       repositories, plugin repositories, and free-form properties to be used as configuration
 
   |       variables for plugins in the POM.

    <!-- profile
 
     | Specifies a set of introductions to the build process, to be activated using one or more of the
 
     | mechanisms described above. For inheritance purposes, and to activate profiles via <activatedProfiles/>
 
     | or the command line, profiles have to have an ID that is unique.
 
     |
 
     | An encouraged best practice for profile identification is to use a consistent naming convention
 
     | for profiles, such as 'env-dev', 'env-test', 'env-production', 'user-jdcasey', 'user-brett', etc.
 
     | This will make it more intuitive to understand what the set of introduced profiles is attempting
 
     | to accomplish, particularly when you only have a list of profile id's for debug.
 
     |
 
     | This profile example uses the JDK version to trigger activation, and provides a JDK-specific repo.
 
    <profile>
 
      <id>jdk-1.4</id>
 
 
 
      <activation>

    -->
 
 
 
    <!--
 
     | Here is another profile, activated by the system property 'target-env' with a value of 'dev',
 
     | which provides a specific path to the Tomcat instance. To use this, your plugin configuration
 
     | might hypothetically look like:
 
     |
 
     | ...

     |       anything, you could just leave off the <value/> inside the activation-property.

主要是配置repository。它的ID对应的是maven中的repository.以便maven能使用nexus搜索和管理组件，极大节约带宽，加速开发。

maven的配置如下：

 
<project xmlns="http://maven.apache.org/POM/4.0.0"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
 
    <modelVersion>4.0.0</modelVersion>
 
    <groupId>com.tudou</groupId>
 
    <artifactId>tudouSystem</artifactId>
 
    <packaging>war</packaging>
 
    <version>0.0.1-SNAPSHOT</version>
 
    <name>tudouSystem Maven Webapp</name>
 
    <!--<url>http://maven.apache.org</url> -->
 
    <properties>
 
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
 
        <tomcatPath>D:\progra\tomcat6</tomcatPath>
 
    </properties>
 
    <distributionManagement>
 
        <repository>
 
            <id>nexus-releases</id>
 
            <name>Nexus Release Repository</name>
 
            <url>http://localhost:8081/nexus/content/repositories/releases/</url>
 
        </repository>
 
        <snapshotRepository>
 
            <id>nexus-snapshots</id>
 
            <name>Nexus Snapshot Repository</name>
 
            <url>http://localhost:8081/nexus/content/repositories/snapshots/
 
            </url>
 
        </snapshotRepository>
 
    </distributionManagement>
 
    <dependencies>
 
        <dependency>
 
            <groupId>javax.servlet</groupId>
 
            <artifactId>javax.servlet-api</artifactId>
 
            <version>3.0.1</version>
 
        </dependency>
 
    </dependencies>
 
    <build>
 
        <plugins>
 
            <!-- Run As Maven build : clean package 就可以发布到tomcat下了，并按照<warName>命名 访问应用时，访问该地址即可：http://IP:Port/warName/ -->
 
            <plugin>
 
                <artifactId>maven-war-plugin</artifactId>
 
                <version>2.2</version>
 
                <configuration>
 
                    <!--默认打包名为项目名称，生成的WAR存放在target下-->
 
                    <warName>tudouSystem</warName>
 
                    <outputDirectory>${tomcatPath}\webapps</outputDirectory>
 
                    <!--修改JSP文件后不能重新编译发布-->
 
                    <webappDirectory>${basedir}/src/main/webapp</webappDirectory>
 
                    <warSourceDirectory>${basedir}/src/main/webapp</warSourceDirectory>
 
                </configuration>
 
            </plugin>
 
        </plugins>
 
    </build>
 
</project>

3，建立你的maven项目。完整的项目结构如图所示，注意它的default-output

maven+snoatype nexus+jrebel+eclipse+tomcat整合的小例子

这是还必须配置tomcat，<Context docBase="E:\java\newwork\tudouSystem\src\main\webapp" path="/tudouSystem" reloadable="false" />

项目的WEB.XML

 
<?xml version="1.0" encoding="UTF-8"?>
 
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee  
 
    http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
 
    <servlet>
 
        <servlet-name>TestServlet</servlet-name>
 
        <servlet-class>com.tudou.web.servlet.TestServlet</servlet-class>
 
    </servlet>
 
    <servlet-mapping>
 
        <servlet-name>TestServlet</servlet-name>
 
        <url-pattern>/TestServlet</url-pattern>
 
    </servlet-mapping>
 
 
 
    <welcome-file-list>
 
        <welcome-file>/TestServlet</welcome-file>
 
    </welcome-file-list>
 
    <display-name>Archetype Created Web Application</display-name>
 
</web-app>

项目的servlet:

package com.tudou.web.servlet;

import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

/**
 * @className:TestServlet.java
 * @classDescription:
 * @author:很拽の土豆
 * @createTime:2012-8-25 上午4:31:48
 */
public class TestServlet extends HttpServlet {
	@Override
	protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
		this.doPost(req, resp);
	}

	@Override
	protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
		req.setAttribute("YouName", "很拽の土豆");
		req.getRequestDispatcher("/index.jsp").forward(req, resp);
	}
}

JSP页面：

 
<%@ page language="java" contentType="text/html; charset=UTF-8"
 
    pageEncoding="UTF-8"%>
 
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
 
<html>
 
<head>
 
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
 
<title>Insert title here</title>
 
</head>
 
<body>
 
<h2>欢迎：${YouName}</h2>
 
</body>
 
</html>

右键：debug as ->maven clean ->package这是项目可以正常访问了。但是修改Servlet后必须重启服务。

3，安装jrebel

eclipse菜单help->eclipse market->install jrebel。next安装完之后会提示你重启。此时不要重启。因为jrebel是付费版。下载破解版jrebel.jar5.0。在eclipse/plugins下面搜索jrebel.jar然后定位到其所在的文件夹，复制进去覆盖。启动eclipse后选中项目debug as ->debug configurion，点击apache tomcat后会看到最后面的jrebel，勾选enabled jrebel。点击run.
