war格式的包可以解决web应用程序部署时候不用按照目录层次结构部署，而是将war包当作部署单元来使用。
下面就讲下怎么去解压 .war 格式的压缩包：
1、安装jdk，我安装的是jdk1.7_64版本的，我在百度网盘上传一份，下载地址是：http://pan.baidu.com/s/1jGs22KQ
2、jdk下载完之后先解压到指定目录下（目录视自己情况而定，我为了方面直接放在root目录下了，下面再做配置文件也是根据这个目录而进行的）
[root@localhost ~]# ls
an install.log jdk-7u76-linux-x64.gz mnt3 下载 文档 视频
anaconda-ks.cfg install.log.syslog mydx_v.2.3.5_PR_15072502.war 公共的 桌面 音乐

3、解压jdk-7u76-linux-x64.gz ：
tar xvf jdk-7u76-linux-x64.gz
jdk1.7.0_76/include/linux/jni_md.h
jdk1.7.0_76/include/jawt.h
jdk1.7.0_76/include/jvmticmlr.h
jdk1.7.0_76/include/classfile_constants.h
[root@localhost ~]# ls
an install.log jdk-7u76-linux-x64.gz mnt3 下载 文档 视频
anaconda-ks.cfg install.log.syslog mydx_v.2.3.5_PR_15072502.war 公共的 桌面 音乐
anzhuangruanjian jdk1.7.0_76 mnt myipt.rule
4、进入jdk1.7.0_76
[root@localhost jdk1.7.0_76]# cd
在环境变量中配置jdk的家目录
[root@localhost ~]# vim /etc/profile
pathmunge /usr/sbin after
pathmunge /sbin after
fi
HOSTNAME=`/bin/hostname 2>/dev/null`
HISTSIZE=1000
if [ "$HISTCONTROL" = "ignorespace" ] ; then
export HISTCONTROL=ignoreboth
else
export HISTCONTROL=ignoredups
46
47 HOSTNAME=`/bin/hostname 2>/dev/null`
48 HISTSIZE=1000
49 if [ "$HISTCONTROL" = "ignorespace" ] ; then
50 export HISTCONTROL=ignoreboth
51 else
52 export HISTCONTROL=ignoredups
53 fi
54
55 export PATH USER LOGNAME MAIL HOSTNAME HISTSIZE HISTCONTROL
56 export PATH=$PATH:/usr/local/mysql/bin
添加下面的代码，目录根据自己的情况而定：
=====================================================
57 JAVA_HOME=/root/jdk1.7.0_76
58 JRE_HOME=/root/jdk1.7.0_76/jre
59 PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin
60 CLASSPATH=.:$JAVA_HOME/lib/jt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib
61 export JAVA_HOME JRE_HOME PATH CLASSPATH
=======================================================
62 # By default, we want umask to get set. This sets it for login shell
63 # Current threshold for system reserved uid/gids is 200
64 # You could check uidgid reservation validity in
65 # /usr/share/doc/setup-*/uidgid file
66 if [ $UID -gt 199 ] && [ "`id -gn`" = "`id -un`" ]; then
67 umask 002
68 else
69 umask 022
70 fi
71
72 for i in /etc/profile.d/*.sh ; do
73 if [ -r "$i" ]; then
74 if [ "${-#*i}" != "$-" ]; then
75 . "$i"
76 else
5、保存之后查看jdk是不是配置成功
命令
java -version
[root@localhost ~]# java -version
java version "1.7.0_76"
Java(TM) SE Runtime Environment (build 1.7.0_76-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.76-b04, mixed mode)
出现这个结果就说明是配置成功
6、解压war包
命令： jar
参数：
-c 创建war包
-v 显示创建过程信息
-u 更新war包
-xvf 提取war中的内容
简单就知道这些命令
现在就要解压war包了，需要用到
jar -vxf ceshi.war
[root@localhost ~]# jar -xvf ceshi.war
inflated: META-INF/MANIFEST.MF
created: META-INF/
created: WEB-INF/
created: WEB-INF/classes/

inflated: WEB-INF/lib/dom4j-1.6.1.jar

解压打当前目录了
那么如何解压到指定目录呢？由于jar命令不支持直接指定解压到某个目录，但是可以先创建一个目录，在此目录里面执行下面命令：
jar -xvf ../ceshi.war
[root@localhost ~]# mkdir ceshi
[root@localhost ~]# cd ceshi
[root@localhost ceshi]# pwd
/root/ceshi
[root@localhost ceshi]# jar -xvf ../ceshi.war
inflated: META-INF/MANIFEST.MF
created: META-INF/
created: WEB-INF/
created: WEB-INF/classes/
created: WEB-INF/classes/com/
created: WEB-INF/classes/com/mydx/
created: WEB-INF/classes/com/mydx/action/
inflated: WEB-INF/classes/com/mydx/action/UploadAction.class
inflated: WEB-INF/classes/struts.xml
created: WEB-INF/lib/
/lib/commons-logging-api-1.1.jar
inflated: WEB-INF/lib/commons-net-ftp-2.0.jar
inflated: WEB-INF/lib/commons-validator-1.3.1.jar
inflated: WEB-INF/lib/dom4j-1.6.1.jar
inflated: WEB-INF/lib/dwr.jar
inflated: WEB-INF/lib/ezmorph-1.0.4.jar
inflated: WEB-INF/lib/freemarker-2.3.16.jar
inflated: WEB-INF/lib/hibernate-c3p0-4.1.2.Final.jar
inflated: WEB-INF/lib/hibernate-commons-annotations-4.0.1.Final.jar
inflated: WEB-INF/lib/hibernate-core-4.1.4.Final.jar
inflated: WEB-INF/lib/hibernate-entitymanager-4.1.4.Final.jar
[root@localhost ceshi]# ls
index.jsp js META-INF upload WEB-INF
这些文件就是解压出来的。
