1:环境
eclipse indigo,
JDK1.6,
maven 3.2.1,
tomcat7.0.42
2:安装eclipse maven插件 m2eclipse
第一种方法:从网上下载m2eclipse,这个网上有很多下载的地方。然后放到eclipse安装目录的plugins下。
第二种方法:打开eclipse->help->install new software。在work with后输入:/technology/m2e/releases。如图:
3:下载maven和tomcat
上apache官网下载maven:/download.cgi。下载完成后解压即可。
上apache官网下载tomcat:/。
4:eclipse配置maven
window-》prefrences-》maven-》user setting。如图
window-》prefrences-》maven-》installations。如图
5:配置tomcat和maven
进入tomcat_home/conf/tomcat_users.xml:修改如下:
[html]view plaincopy print? <rolerolename="admin-gui"/> <rolerolename="admin-script"/> <rolerolename="manager-gui"/> <rolerolename="manager-script"/> <rolerolename="manager-jmx"/> <rolerolename="manager-status"/> <userusername="admin"password="admin"roles="manager-gui,manager-script,manager-jmx,manager-status,admin-script,admin-gui"/>
进入maven_home/conf/settings.xml:修改如下:
[html]view plaincopy print? <server> <id>tomcat</id> <username>admin</username> <password>admin</password> </server>
6:eclipse创建maven web项目
这个简单,new-》other-》maven project-》next。这里注意groupid选org.apache.maven.archetypes,artifactid 选maven-archetype-webapp,然后next,输入我们自己的groupid(com.test),artifactid(transition),然后finish,OK。如图所示:
7:修改pom.xml
[html]view plaincopy print? <projectxmlns="/POM/4.0.0"xmlns:xsi="/2001/XMLSchema-instance" xsi:schemaLocation="/POM/4.0.0/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.test</groupId> <artifactId>transition</artifactId> <packaging>war</packaging> <version>0.0.1</version> <name>transitionMavenWebapp</name> <url></url> <repositories> <repository> <id>maven_remote_1</id> <url>/pub/mirrors/maven2/</url> </repository> </repositories> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> </dependencies> <build> <finalName>transition</finalName> <plugins> <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>tomcat-maven-plugin</artifactId> <configuration> <warFile>target/transition.war</warFile> <server>tomcat</server> <url>http://localhost:8080/manager/text</url> <path>/transition</path> </configuration> </plugin> </plugins> </build> </project>8:运行maven项目
先进入tomcat目录启动tomcat,然后右键项目 run as-》run configrations:
Goals项输入:package tomcat:redeploy
Maven Runtime选择我们自己的maven。如图:
然后点Run,控制台显示如下:
[plain]view plaincopy print? [INFO]Processingwarproject [INFO]Copyingwebappresources[E:\transition\src\main\webapp] [INFO]Webappassembledin[3msecs] [INFO]Buildingwar:E:\transition\target\transition.war [INFO]WEB-INF\web.xmlalreadyadded,skipping [INFO] [INFO]<<<tomcat-maven-plugin:1.1:redeploy(default-cli)@transition<<< [INFO] [INFO]---tomcat-maven-plugin:1.1:redeploy(default-cli)@transition--- [INFO]Deployingwartohttp://localhost:8080/transition [INFO]OK-Undeployedapplicationatcontextpath/transition [INFO]OK-Deployedapplicationatcontextpath/transition [INFO]------------------------------------------------------------------------ [INFO]BUILDSUCCESS [INFO]------------------------------------------------------------------------ [INFO]Totaltime:2.412s [INFO]Finishedat:-03-13T11:43:42+08:00 [INFO]FinalMemory:6M/15M [INFO]------------------------------------------------------------------------
这里省略很多控制台输出,出现BUILD SUCCESS 则说明部署成功,浏览器输入:http://localhost:8080/transition/。显示Hello world..
注意:这样成功之后项目会直接打成war包,部署到tomcat下,每次build不需要重启tomcat。这样致命的缺点就是,不能调试。如果需要调试且在eclipse中启动tomcat的话。会发现右键项目没有run as server,有两种方法解决:
第一种:这时需要把项目转变成dynamic web module。右键项目-》properties-》project facets,然后右边选中dynamic web module。之后就会出现run as server了.
第二种:右键项目,run/debug as configrations 如上第8步骤的图。不过Goals中天上【tomcat:run】。然后run就OK了,注意这里不需要提前启动tomcat。
