一、针对单个文件打jar包

![20200114111546585.png][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3NpbmF0XzM0MzM4MTYy_size_16_color_FFFFFF_t_70][]

3.jar 会输出在  D:\\ideasvn\\out\\artifacts

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3NpbmF0XzM0MzM4MTYy_size_16_color_FFFFFF_t_70 1][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3NpbmF0XzM0MzM4MTYy_size_16_color_FFFFFF_t_70 2][]

如下：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3NpbmF0XzM0MzM4MTYy_size_16_color_FFFFFF_t_70 3][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3NpbmF0XzM0MzM4MTYy_size_16_color_FFFFFF_t_70 5][]

9.jar 会输出在  D:\\ideasvn\\out\\artifacts

注意：如果是springboot项目打包成jar 给别的项目引用

<plugins>
    需要把默认打去掉
       <!<plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin> -->
    替换成下面这个
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <configuration>
                <source>1.8</source>
                <target>1.8</target>
                <encoding>UTF-8</encoding>
    
            </configuration>
        </plugin>

二、使用

1. 非maven 项目直接eclipse 导入

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3NpbmF0XzM0MzM4MTYy_size_16_color_FFFFFF_t_70 6][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3NpbmF0XzM0MzM4MTYy_size_16_color_FFFFFF_t_70 7][]

使用：代码

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3NpbmF0XzM0MzM4MTYy_size_16_color_FFFFFF_t_70 8][]

输出![20200114113256889.png][]

2.maven 项目 springboot

1.先准备好本地jar包，然后在项目的resources目录创建 lib 目录，把本地jar包放进 lib 下

![20200114163812181.png][]

2.在Pom.xml中引用本地jar包

<dependency>
        <groupId>com.kry.tableutils</groupId>
        <artifactId>tableutils</artifactId>
        <version>0.0.3</version>
        <scope>system</scope>
        <systemPath>${project.basedir}/src/main/resources/lib/krytest.jar</systemPath>
    </dependency>

<dependency>
       <groupId>org.apache</groupId> 
       <artifactId>test</artifactId> 
       <version>1.0</version>
       <scope>system</scope> 
       <systemPath>${basedir}/src/main/webapp/WEB-INF/lib/1.3.3_encrypt.jar</systemPath>
    </dependency>

3.此时就可以在本地开发引用 该包

执行方法能成功。

4.    此时将项目打成jar包，部署运行会发现找不到 krytest.jar 里面的类

5. 这时候在pom。xml中添加` ``<includeSystemScope>``true``</includeSystemScope> 主要作用`

<plugins>
      
            <plugin>
                <artifactId>maven-compiler-plugin</artifactId>
                <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                    <encoding>UTF-8</encoding>
                    <compilerArguments>
                        <extdirs>${project.basedir}/src/main/resources/lib</extdirs>
                    </compilerArguments>
                </configuration>
            </plugin>
        
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <configuration>
                <executable>true</executable>
                <includeSystemScope>true</includeSystemScope>
            </configuration>
        </plugin>
    </plugins>

6.打jar包，部署，执行方法成功
