一、引入包

链接: https://pan.baidu.com/s/13V2ihOpRoLf3R9MFCH2kHQ?pwd=be64 提取码: be64 复制这段内容后打开百度网盘手机App，操作更方便哦

1.1在pom引入

<dependency><groupId>com.aspose</groupId><artifactId>aspose-words</artifactId><version>15.8.0</version><scope>system</scope><systemPath>${project.basedir}/lib/aspose-words-15.8.0.jar</systemPath></dependency>

1.2 因为我们的项目是打包成jar,所以以上方法在本地idea运行没有问题，linux系统不行

1.2.1解决方法1

<build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId><!-- 打包时会将本地jar一起打包 --><configuration><includeSystemScope>true</includeSystemScope></configuration>     </plugin></plugins>
</build>

或者是

<build><resources><resource><directory>lib</directory><targetPath>/BOOT-INF/lib/</targetPath><includes><include>**/*.jar</include></includes></resource></resources></build>

1.2.2解决方法2

对比方法一，我觉得还是挺垃圾的，谁想动一个摇摇欲坠的项目

         <dependency><groupId>com.aspose</groupId><artifactId>aspose-words</artifactId><version>15.8.0</version></dependency>
该语句中参数：
DgroupId ：组id 【对应pom中的groupId】
DartifactId：项目id 【对应pom中的artifactId】
Dversion：版本号 【对应pom中的version】
Dfile：jar包的绝对路径
Dpackaging：是什么包
DgeneratePom：是否生成pom

直接使用maven命令

mvn install:install-file -Dfile=C:\\Users\\yhc\\Desktop\\aspose-words-15.8.0.jar -DgroupId=com.aspose -DartifactId=aspose-words -Dversion=15.8.0 -Dpackaging=jar -DgeneratePom=true

不想运行也没关系，我放在云盘了，自行拷贝

生成这个文件夹，把这个放在你们的maven仓库就行了

二、配置文件–License.xml–去除水印

2.1 license.xml直接放到resources的根目录下即可

<License><Data><Products><Product>Aspose.Total for Java</Product><Product>Aspose.Words for Java</Product></Products><EditionType>Enterprise</EditionType><SubscriptionExpiry>20991231</SubscriptionExpiry><LicenseExpiry>20991231</LicenseExpiry><SerialNumber>8bfe198c-7f0c-4ef8-8ff0-acc3237bf0d7</SerialNumber></Data><Signature>sNLLKGMUdF0r8O1kKilWAGdgfs2BvJb/2Xp8p5iuDVfZXmhppo+d0Ran1P9TKdjV4ABwAgKXxJ3jcQTqE/2IRfqwnPf8itN8aFZlV3TJPYeD3yWE7IT55Gz6EijUpC7aKeoohTb4w2fpox58wWoF3SNp6sK6jDfiAUGEHYJ9pjU=</Signature>
