idea制作工具类打成jar包给web引用

ゝ一世哀愁。 2023-07-24 03:24 15阅读 0赞

先找到我们的project structure

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2JveXdjeA_size_16_color_FFFFFF_t_70][]

点击之后出现新窗口，依次选择Artifacets ->选中+号->JAR->Empty

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2JveXdjeA_size_16_color_FFFFFF_t_70 1][]

填写自己制作的jar包名称，然后点击Directory Content

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2JveXdjeA_size_16_color_FFFFFF_t_70 2][]

这里会弹出一个窗口，进行选择自己的class文件目录，这个class文件就是你想要的java类进行编译之后存放的目录，不是java类存放的目录，重要的事情说三遍。一般maven项目进行编译后的class文件都会在target目录下存放。

选中我们需要的class的目录之后，点击OK，然后外部也点击apply和OK即可

然后点击Build 选中Build Artfacts

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2JveXdjeA_size_16_color_FFFFFF_t_70 5][]

会出现下列框，直接点击Build即可。

我们回到前面步骤看一下导出的路径在哪

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2JveXdjeA_size_16_color_FFFFFF_t_70 6][]

如图所示：

接下来的步骤就是将我们把jar包放到lib目录下

然后在pom文件引入以下依赖

注意：groupId和artifactId可以随便写，systemPath路径中project.basedir指代当前项目的根路径，根据自己的lib所在路径进行写入即可

<dependency>
        <groupId>com.myjar</groupId>
        <artifactId>com.myjar</artifactId>
        <version>1.0</version>
        <scope>system</scope>
        <systemPath>${project.basedir}/src/main/resources/lib/myjar.jar</systemPath>
    </dependency>
