maven部署web项目到tomcat7(兼容tomcat8)

1.下载tomcat7并配置好JAVA_HOME,tomcat7\webapps目录除了manager之外,其它都可以删除(删除没用的,可加速tomcat的启动).

2.tomcat7\conf\tomcat-users.xml加入

<role rolename="manager-gui"/>
<role rolename="manager-script"/>
<user username="username" password="password" roles="manager-gui,manager-script"/>

当然用户名和密码可以不一样,但没有manager-gui就不能通过浏览器去访问manage应用,没有manager-script就不能通过manage去上传war包达到部署的目的.

3.在web项目的pom.xml的一个应用例子(注:url也必须有/text,否则也上传不了war包)

4.tomcat7要先启动,在命令行转到项目目录下输入d:\maven3\bin\mvn tomcat7:deploy看结果.(注:不是tomcat:deploy)

在eclipse配置好外部的maven,在eclipse的run configurations建一个Maven Build:Name随便起一个名字(如tomcat7_redeploy),Base directory选项目目录${workspace_loc:/testweb},goals填tomcat7:deploy.或tomcat7:redeploy

deploy:如果已经部署过,再deploy就会失败.去tomcat7的webapps删除已经部署过的就行了.

redeploy:即使没部署过也不会失败.不知道build的速度会不会明显减慢??

至于选deploy还是redeploy,自己看着办吧!

直至今天(2013-11-11)还没看到有tomcat8-maven-plugin,但tomcat7-maven-plugin的2.2版已经兼容tomcat8.

只到2.2:https://repository.apache.org/content/repositories/maven-staging-group/org/apache/tomcat/maven/

snapshots看到有2.3:https://repository.apache.org/content/repositories/snapshots/org/apache/tomcat/maven/
