使用idea 引入第三方库，使用assembly插件打包包含第三方库的上线包

1.首先创建一个lib目录，将第三方jar包放到lib目录下。

2.选择菜单File -> Project Structure

3.打开Project Structure后，选择Modules -> Dependencies -> + -> JARS or directories...

4.选择你最开始创建的lib路径，点击OK,保存就好了。idea引入第三方库完成！

引入第三方库后，可以通过assembly插件将项目打包成上线包。

pom.xml中需要引入assembly插件

<build>
    <sourceDirectory>src/main/java</sourceDirectory>

        <resource>

</build>

assembly.xml配置文件如下：

<assembly>
   <id>assembly</id>
   <formats>
      <format>zip</format>
      <!--<format>jar</format>-->
   </formats>
   <includeBaseDirectory>false</includeBaseDirectory>
   <fileSets>
      <!-- -->
      <fileSet>
         <directory>src/main/resources</directory>
         <outputDirectory>conf</outputDirectory>       
         <includes>
                <include>*.xml</include>
                <include>*.properties</include>       
             <include>**/*.xml</include>              
               <include>**/*.properties</include>
          </includes>

         <fileMode>0644</fileMode>
      </fileSet>
      <fileSet>
         <directory>src/main/lib</directory>
         <outputDirectory>lib</outputDirectory>
         <includes>
            <include>*.jar</include>
         </includes>
         <fileMode>0644</fileMode>
      </fileSet>
      <fileSet>
         <directory>src/main/assembly/bin</directory>
         <outputDirectory>bin</outputDirectory>
         <fileMode>0755</fileMode>
      </fileSet>
   </fileSets>
   <dependencySets>
      <dependencySet>
         <outputDirectory>lib</outputDirectory>
      </dependencySet>
   </dependencySets>
</assembly>

其中下面这一段配置就是将的第三方库打包到最后的上线包的lib目录中去。

      <fileSet>
         <directory>src/main/lib</directory>
         <outputDirectory>lib</outputDirectory>
         <includes>
            <include>*.jar</include>
         </includes>
         <fileMode>0644</fileMode>
      </fileSet>
