FatJar方式：

在Eclipse下生成jar包分很多种情况。最简单的情况是没有用到第三方jar包，那么直接Export就可以生成jar包。但是如果用到了第三方jar包，那么就比较繁琐了，很不方便。FatJar可以解决这个问题，使用FatJar，即使包含了很多第三方jar包，也可以很方便的生成jar包。

安装方法：

1. eclipse在线更新方法：help > Install New Sofware > Add...

name：FatJar

URL：http://kurucz-grafika.de/fatjar

2. eclipse插件安装方法：

解压后，将解压出的plugins中的文件复制到eclipse中的plugins目录下

然后重启eclipse，避免Fat Jar被认不出来，在eclipse启动时使用-clean参数

使用Ant打包是比较方便的，我们可以在项目根目录下建立一个名为build.xml的xml文件，然后在xml文件里面定义我们的打包任务，如下：

打jar 包时文件内容：

<project default="jar" name="edi_salary_pfm">    <property name="lib.dir" value="lib"/>    <property name="src.dir" value="src"/>    <property name="resource.dir" value="${src.dir}/resources"/><property name="output.dir" value="build"/>    <property name="classes.dir" value="${output.dir}/classes"/>    <property name="jarname" value="edi_salary_pfm"/>     <!-- 第三方jar包的路径 -->    <path id="lib-classpath">    <fileset dir="${lib.dir}">    <include name="**/*.jar"/>    </fileset>    </path>    <path id="base.path"><!-- 需要在window->preferences->ant->runtime->properties 加上common_lib变量，指向hrms_common_lib的根目录 --><fileset dir="D:\source\truck\common_lib"><include name="*.jar" /></fileset></path><!-- 1. 初始化工作，如创建目录等 -->    <target name="init">    <mkdir dir="${classes.dir}"/>    <mkdir dir="${output.dir}"/>    </target>    <!-- 2. 编译 -->    <target name="compile" depends="init">    <javac srcdir="${src.dir}" destdir="${classes.dir}">   <compilerarg line="-encoding UTF-8"/>    <classpath refid="lib-classpath"/>    <classpath refid="base.path"/>    </javac><copy todir="${classes.dir}"><fileset dir="${resource.dir}"></fileset></copy></target>    <!-- 3. 打包jar文件 -->    <target name="jar" depends="compile">    <copy todir="${output.dir}/lib">  <fileset dir="${lib.dir}"/>    </copy>    <!--Create a property containing all .jar files,    prefix lib/, and seperated with a space-->    <pathconvert property="mf.classpath" pathsep=" ">    <mapper>    <chainedmapper>    <!-- jar包文件只留文件名，去掉目录信息 -->    <flattenmapper/>    <!-- add lib/ prefix -->    <globmapper from="*" to="lib/*"/>    </chainedmapper>    </mapper>    <path refid="lib-classpath"/>    <path refid="base.path"/>  </pathconvert>    <!-- jar文件的输出路径     需要比对一下先前的打包buid.xml文件看看要过滤掉那些文件   --><jar jarfile="${output.dir}/${jarname}.jar"><fileset dir="${classes.dir}"><!--<exclude name="**/config/**"/><exclude name="**/spring/dataAccessContext.xml"/><exclude name="ibatis/sql-map-config.xml"/><exclude name="spy.properties"/>--></fileset></jar></target>
</project>

打war包文件内容：
