一、原理
自行到猿小武的博客:https://blog.csdn.net/xxw19950701/article/details/115724571进行了解。
二、准备aspose-words-21.1.0-jdk17.jar
aspose-words-21.1.0-jdk17.jar
下载地址。如果失败下载不了,可能tick失效了,自己到官网[https://www.aspose.com/#]注册一个账号。到[https://downloads.aspose.com/words/java]找到[Aspose.Words for Java 21.1]进行下载。
三、反编译
-
引入反编译工具
<dependency> <groupId>org.javassist</groupId> <artifactId>javassist</artifactId> <version>3.27.0-GA</version> </dependency>
-
反编译
public static void main(String[] args) throw Exception { //这一步是完整的jar包路径 ClassPool.getDefault().insertClassPath("/Users/langkye/Development/Personal/awesome-auth/tester/lib/aspose-words-21.1.0-java/lib/aspose-words-21.1.0-jdk17.jar"); CtClass zzZJJClass = ClassPool.getDefault().getCtClass("com.aspose.words.zzZE0"); CtMethod zzZ4h = zzZJJClass.getDeclaredMethod("zzZ4h"); CtMethod zzZ4g = zzZJJClass.getDeclaredMethod("zzZ4g"); zzZ4h.setBody("{return 1;}"); zzZ4g.setBody("{return 1;}"); //反编译后的“zzZE0.class"保存目录[xxx/com/aspose/words/zzZE0.class] zzZJJClass.writeFile("/Users/langkye/Development/Personal/awesome-auth/tester/lib"); }

重新打包
# 1.将官网下载的jar[aspose-words-21.1.0-jdk17.jar]拆包。 # 拆包后的目录: # ./. # |__com/aspose/words/ # | |__... # | |__zzZE0.class(删除zzZE0.class文件。这个文件会通过反编译重新生成进行替换。) # |__META-INF/ # | |__... # | |__xxx.SF(删除.SF文件) # | |__xxx.RSA(删除.RSA文件) # |__/ # tar -zxvf aspose-words-21.1.0-jdk17.jar # 2.删除文件 # 删除[com/aspose/words/zzZE0.class]、[META-INF/xxx.SF]、[META-INF/xxx.RSA]文件。 # 3.替换原文件 # 将反编译生成的[zzZE0.class]替换掉[com/aspose/words/zzZE0.class] # 4.打包 jar cvfm aspose-words-21.1.0-jdk17.jar META-INF/MANIFEST.MF com/ # 5.安装到本地maven仓库(可选) mvn install:install-file\ -Dfile=/Users/langkye/Development/Personal/awesome-auth/tester/lib/new/aspose-words-21.1.0-jdk17.jar\ -DgroupId=com.aspose\ -DartifactId=aspose-words\ -Dversion=21.1.0\ -Dpackaging=jar
四、使用
-
在项目中引入
-
引入安装到maven仓库的依赖(二选一)。
<dependency> <groupId>com.aspose</groupId> <artifactId>aspose-words</artifactId> <version>21.1.0</version> </dependency>
-
引入项目中lib的依赖(二选一)。
<dependency> <groupId>com.aspose</groupId> <artifactId>aspose-words</artifactId> <version>21.1.0</version> <scope>system</scope> <systemPath>${project.basedir}/lib/aspose-words-21.1.0-jdk17.jar</systemPath> </dependency> <!-- 打包需要稍作修改 --> <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> <!-- 引入系统scope级别的jar --> <includeSystemScope>true</includeSystemScope> </configuration> </plugin> </plugins> </build>

测试·Word转PDF
public static void main(String[] args) throws Exception { // inPath = word文档的本地路径和名称 String inPath = "/Users/langkye/Downloads/16359649365739982767.docx"; // outPath = 输出的pdf文件的路径和名称 String outPath = "/Users/langkye/Desktop/aspose_word_test.pdf"; long old = System.currentTimeMillis(); File file = new File(outPath); FileOutputStream os = new FileOutputStream(file); Document doc = new Document(inPath); doc.save(os, SaveFormat.PDF); long now = System.currentTimeMillis(); System.out.println("convert OK! " + ((now - old) / 1000.0) + "秒"); }
