Ant之启动和停止tomcat

一般在大型的软件编译，打包，部署都离不开ant,例如我们在执行 ant deploy的command的时候不仅仅要打包成war包，还需要启动tomcat,启动包括直接start,以及debug模式启动，和stop tomcat.

<!-- Launches Tomcat -->
	<target name="tomcat-start"
		    description="Launches Tomcat">
		<fail unless="env.TOMCAT_HOME"
			message="You must set the TOMCAT_HOME environment variable to point to your Tomcat installation folder"/>
		<exec dir="${env.TOMCAT_HOME}/bin" executable="catalina.bat"
			vmlauncher="false" spawn="true">
			<arg value="start"/>
		</exec>
	</target>

	<!-- Launches Tomcat in debug mode -->
	<target name="tomcat-start-debug"
		    description="Launches Tomcat in JDPA debug mode on port 8000">
		<fail unless="env.TOMCAT_HOME"
			message="You must set the TOMCAT_HOME environment variable to point to your Tomcat installation folder"/>
		<exec dir="${env.TOMCAT_HOME}/bin" executable="catalina.bat"
			vmlauncher="false" spawn="true">
			<arg value="jpda"/>
			<arg value="start"/>
			<env key="JPDA_ADDRESS" value="8000"/>
			<env key="JPDA_TRANSPORT" value="dt_socket"/>
		</exec>
	</target>
<!-- Shuts down Tomcat -->
	<target name="tomcat-stop"
		    description="Shuts down Tomcat">
		<fail unless="env.TOMCAT_HOME"
			message="You must set the TOMCAT_HOME environment variable to point to your Tomcat installation folder"/>
		<exec dir="${env.TOMCAT_HOME}/bin" executable="shutdown.bat"
			vmlauncher="false" spawn="true"/>
		<sleep seconds="2"/>
	</target>

dt_socket:表示使用远程调式(dt_shmem表示本地调式),采用类似注入变量的形式去设置一些启动属性,避免手动修改catalina.bat文件。
