打包参数:
mvn package -P saas -Dwar.name=dfxd -Ddb.name=dfxd
注意:D参数可以使用多次，匹配pom.xml里面定义的属性。

maven 生成的jar文件指定main class [url]http://qinglangee.iteye.com/blog/709961[/url]

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

						</manifest>
					</archive>
				</configuration>
			</plugin>
		</plugins>
	</build>

</project>

jar 命令:

假设现在是在classes目录的同级目录中

[color=darkblue]jar cvef zhch.illq.time.TimeTool timetool.jar -C classes . [/color]

-C 是指定要打包的目录

. (点) 是文件,表示当前目录,这样就把classes目录中及子目录中所有文件打包

参数e f 分别指定main class和生成的jar文件名, 后面要按顺序来

也可以写成这样

[color=darkblue]jar cvfe timetool.jar zhch.illq.time.TimeTool -C classes . [/color]

[b]maven 将代码打成可执行jar包[/b] [url][/url]

在Eclipse中编写代码，如果没有用到第三方jar可以直接export成jar包，但是如果用到第三方jar包，就需要手动将拷贝依赖的jar包，也可以编写ant脚本自动打包。更方便的是使用maven，现在maven管理项目很方便，如下面将自己编写的类打成可执行jar包，并自动拷贝依赖的jar包。下面是pom.xml文件：

        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

                            ./target/lib
                         </outputDirectory>
                         </configuration>

执行 maven install就会在项目target文件夹下生成jar包，和依赖的jar包（在lib文件夹中），直接运行 [color=darkblue]java -jar *.jar[/color]即可。

[size=x-large][color=red]2. 打war包时排除resource[/color][/size]

<build>   
  <plugins>
   <plugin>   
    <groupId>org.apache.maven.plugins</groupId>   
    <artifactId>maven-war-plugin</artifactId>   
    <version>2.0.2</version>   
    <configuration>   
     <warSourceExcludes>src/main/resources/**</warSourceExcludes>   
    </configuration>   
   </plugin>   
  </plugins>   
 </build>

打包时过滤和包含文件例子

<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-war-plugin</artifactId>
				<configuration>
					<escapeString>\</escapeString>
					<warName>${war.name}-${version.num}</warName>
					<warSourceExcludes>src/main/resources/packaged/**</warSourceExcludes>
					<webResources>
						<resource>
							<directory>src/main/resources/packaged</directory>
							<targetPath>WEB-INF/classes</targetPath>
							<filtering>true</filtering>
							<includes>
								<include>hibernate.properties</include>
							</includes>
						</resource>
                        <resource>
                            <directory>src/main/resources/packaged/tmp</directory>
                            <targetPath>WEB-INF/classes</targetPath>
                            <filtering>true</filtering>
                            <includes>
                                <include>applicationContext-init.xml</include>
                            </includes>
                        </resource>
					</webResources>
                    <warSourceDirectory>src/main/webapp</warSourceDirectory>
                    <webXml>src/main/resources/packaged/tmp/web.xml</webXml>
				</configuration>
			</plugin>

注意：pom.xml定义的一些属性，是可以被使用到applicationContext.xml里面的，

比如:pom.xml存在<hibernate.dialect>[color=red]org.hibernate.dialect.SQLServerDialect[/color]</hibernate.dialect>，然后jdbc.properties存在hibernate.dialect=${hibernate.dialect}，applicationContext.xml存在<prop key="hibernate.dialect">${hibernate.dialect}</prop>，那么打包得到的war，applicationContext.xml会变为：<prop key="hibernate.dialect">[color=red]org.hibernate.dialect.SQLServerDialect[/color]</prop>
