要用到工具：

1. Maven 3
2. Tomcat 6.0.37
3. Tomcat 7.0.53

1. Tomcat 7 示例

這個例子說明了如何在Tomcat7打包並部署WAR文件。

1.1 Tomcat 認證
添加具有角色管理器GUI和管理腳本的用戶。

%TOMCAT7_PATH%/conf/tomcat-users.xml

<?xml version='1.0' encoding='utf-8'?>
<tomcat-users>

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

</tomcat-users>

1.2 Maven 認證
添加在上麵Maven 設置文件的 Tomcat 用戶，是之後Maven使用此用戶來登錄Tomcat服務器。

%MAVEN_PATH%/conf/settings.xml

<?xml version="1.0" encoding="UTF-8"?>
<settings ...>
	<servers>
	   
		<server>
			<id>TomcatServer</id>
			<username>admin</username>
			<password>password</password>
		</server>

	</servers>
</settings>

1.3 Tomcat7 Maven 插件
聲明一個Maven的Tomcat插件。

pom.xml

	<plugin>
		<groupId>org.apache.tomcat.maven</groupId>
		<artifactId>tomcat7-maven-plugin</artifactId>
		<version>2.2</version>
		<configuration>
			<url>http://localhost:8080/manager/text</url>
			<server>TomcatServer</server>
			<path>/yiibaiWebApp</path>
		</configuration>
	</plugin>

怎麼運行的？
在部署過程中，它告訴 Maven 通過部署 WAR 文件Tomcat服務器， “http://localhost:8080/manager/text” , 在路徑“/yiibaiWebApp“上, 使用 “TomcatServer” (settings.xml) 用戶名和密碼來進行認證。

1.4 發布到Tomcat
以下的命令是用來操縱Tomcat WAR文件。

mvn tomcat7:deploy 
mvn tomcat7:undeploy 
mvn tomcat7:redeploy

示例

> mvn tomcat7:deploy

...

2. Tomcat 6 示例

這個例子說明了如何在Tomcat6打包和部署WAR文件。這些步驟和Tomcat7是一樣的，隻是部署URL和命令名稱不同。

2.1 Tomcat 認證

%TOMCAT6_PATH%/conf/tomcat-users.xml

<?xml version='1.0' encoding='utf-8'?>
<tomcat-users>

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

</tomcat-users>

2.2 Maven 認證

%MAVEN_PATH%/conf/settings.xml

<?xml version="1.0" encoding="UTF-8"?>
<settings ...>
	<servers>
	   
		<server>
			<id>TomcatServer</id>
			<username>admin</username>
			<password>password</password>
		</server>

	</servers>
</settings>

2.3 Tomcat6 Maven 插件

pom.xml

<plugin>
		<groupId>org.apache.tomcat.maven</groupId>
		<artifactId>tomcat6-maven-plugin</artifactId>
		<version>2.2</version>
		<configuration>
			<url>http://localhost:8080/manager</url>
			<server>TomcatServer</server>
			<path>/yiibaiWebApp</path>
		</configuration>
	</plugin>	

2.4 發布到Tomcat

mvn tomcat6:deploy 
mvn tomcat6:undeploy 
mvn tomcat6:redeploy

示例

> mvn tomcat6:deploy

...
