将Maven项目打包成可执行jar文件和外种配置方式(引用第三方jar)

http://blog.csdn.net/zhangdaiscott/article/details/6911640

方法一. mvn assembly 或 mvn package (一个jar包)

把依赖包和自己项目的文件打包如同一个jar包(这种方式对spring的项目不支持)

[html] view plain copy

1.   <build>  
2.       <plugins>  
3.           <plugin>  
4.               <artifactId>maven-assembly-plugin</artifactId>  
5.               <configuration>  
6.                   <archive>  
7.                       <manifest>  
8.                           <mainClass>com.tang.CSVUtils</mainClass>  
9.                       </manifest>  
10.                   </archive>  
11.                   <descriptorRefs>  
12.                       <descriptorRef>  
13.                           jar-with-dependencies  
14.                       </descriptorRef>  
15.                   </descriptorRefs>  
16.               </configuration>  
17.               <!-- 加上下面这一段,使用 mvn package命令,不加则使用mvn assembly-->  
18.               <!-- <executions>     
19.                   <execution>  
20.                       <id>make-assemble</id>  
21.                       <phase>package</phase>  
22.                       <goals>  
23.                           <goal>single</goal>  
24.                       </goals>  
25.                   </execution>  
26.               </executions> -->  
27.           </plugin>  
28.       </plugins>  
29.   </build>  

Eclipse 中 Run As--- Maven clean ---Maven assembly:assembly（或 Maven package）

Target目录生成如下文件：

其中，

testLog4j-0.1.jar 是不可直接运行的，因为没有带第三方包。

testLog4j-0.1-jar-with-dependencies.jar 就是带有第三方包的可执行 jar 包，

在命令行执行 java -jar testLog4j-0.1-jar-with-dependencies.jar 即可运行

方法二：mvn package(一个jar包和一个lib文件夹)

[html] view plain copy

1. <build>  
2.     <plugins>  
3.         <plugin>  
4.             <groupId>org.apache.maven.plugins</groupId>  
5.             <artifactId>maven-jar-plugin</artifactId>  
6.             <version>2.4</version>  
7.             <configuration>

28.                         <outputDirectory>${project.build.directory}/lib</outputDirectory>  
29.                     </configuration>  
30.                 </execution>  
31.             </executions>  
32.         </plugin>  
33.     </plugins>  
34. </build>    

执行maven package 进行打包进入target目录。

其中lib就是第三方jar包的目录，在其他项目引入testLog4j-0.1.jar会自动找到并引入lib里面的包.

只需要拷贝这两个（lib和testLog4j-0.1.jar）即可放到其他地方用了。

在命令行执行：java -jar testLog4j-0.1.jar

方法三：mvn package(推荐)(一个zip包，里面有一个jar包，一个lib文件夹，和一个conf文件夹)

(1)conf/package.xml (conf 文件夹和pom.xml在同一级目录) [html] view plain copy

mvn install后，此时会在target目录下生成一个zip文件，如：  youArtifactId-0.0.1-bin.zip 解压后有： conf 文件夹， lib文件夹，  youArtifactId-0.0.1-bin.jar
