 ？？近几天一些同学们总是询问小编Eclipse中如何迅速导入jar包?本教程就为大伙带来了Eclipse中迅速导入jar包的具体操作方法介绍。 

  

 ？？- 方法01·最常用的普通操作方式:基本步骤式 

 ？？右击“项目”→选择Properties，在弹出的对话框左侧列表中选择Java Build Path，如下图所示：选择Add External JARs，就可以逐个(也可以选择多个jar，但是限制在同一个文件夹中)添加第三方引用jar包。 

 ？？上面这种方式的操作具有通用性，但是每次创建项目，都需要重新引入Jar包，Jar包不具有可重用性。 

 ？？- 方法02·快速版的操作方式:用户Jar包式 

 ？？右击“项目”→选择Properties，在弹出的对话框左侧列表中选择Java Build Path，弹出如上图所示的对话框，这里选择"Add Library"，弹出如下图所示对话框，选择"User Library"，然后选择→Next 

 ？？在出现的对话框中，可以选择已经创建好的用户自定义库，也可以选择User Libraries，弹出的新对话框中选择"New"，创建新的用户自定义库。 

 ？？在待创建用户自定义库中，输入新的自定义库的名字,如下图 

 ？？然后为新库，添加所需的Jar包 

 ？？按上述步骤添加好用户自定义库后，以后可以重用这些已定义好的User Library库，为开发节省时间。 

 ？？- 方法03·快速版的操作方式:文件夹导入式 

 ？？在项目中，创建新的文件夹(eg:ibatis_jar)，如下图所示，本示例中创建了ibatis_jar文件夹 ，并将项目开发需要的第三方的jar包拷贝到该文件夹中。 

 ？？选中需要添加到项目中的jar包，右键选择"Build PathàAdd to Build Path"，这样Jar包就成功导入到项目中了。 

 ？？第三种导入Jar包的方式比第二种更简单，而且重用性更强，当我们不同的机器上查找所需的Jar包时，将这些文件夹直接拷贝就可以。 

 ？？-· Eclipse导入jar包快捷键 ·- 

 ？？方法一：直接通过”ctrl+shfit+o“引入。 

 ？？第一步：找到要引入包的java类，之后直接点击”ctrl+shfit+o“，会出现如下图所示界面。 

 ？？第二步：根据实际需要，分别选择弹出框中的类即可。 

 ？？方法二：直接在要引入的类上右击，在”source“中选择”Organize import“引入也可以完成。 

 ？？按照上文讲述的Eclipse中迅速导入jar包的具体操作方法介绍，你们自己也赶快去试试吧!
