前言
使用外部手动添加的jar到项目,打包时出现jar找不到问题解决
处理
例如项目结构如下
 
 引入方式换成这种
	<!-- 除了一下这两种引入外部jar,还是可以将外部jar包添加到maven中(百度查)-->
	<!-- pdf转word -->
	<dependency>
	    <groupId>com.aspose</groupId>
	    <artifactId>aspose-pdf</artifactId>
	    <version>22.5</version>
	    <scope>system</scope>
	    <systemPath>${project.basedir}/lib/aspose-pdf-22.5.cracked.jar</systemPath>
	</dependency>
	<!-- excel转pdf -->
	<dependency>
	    <groupId>com.external</groupId>
	    <artifactId>aspose-cells</artifactId>
	    <version>8.5.2</version>
	    <scope>system</scope>
	    <systemPath>${project.basedir}/lib/aspose-cells-8.5.2.jar</systemPath>
	</dependency>
 
这里打包war生成的jar会在lib-provided,所以要指定,不然就算打包成功也会报错找不到类的
	<build>
        <plugins>
            <!-- 打包外部jar需要-->
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <includeSystemScope>true</includeSystemScope>
                </configuration>
            </plugin>
            <!-- 打包war防止上面引入的本地jar添加到 lib-provided 文件夹中而读取不了-->
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-war-plugin</artifactId>
                <configuration>
                    <webResources>
                        <resource>
                            <directory>${project.basedir}/lib</directory>
                            <targetPath>WEB-INF/lib/</targetPath>
                            <includes>
                                <include>**/*.jar</include>
                            </includes>
                        </resource>
                    </webResources>
                </configuration>
            </plugin>
        </plugins>
    </build>
 
这样打包后即可!
你也可以将这些jar包添加到本地maven然后正常引入
