引入依赖
具体
<dependency><groupId>net.sf.jacob-project</groupId><artifactId>jacob</artifactId><version>1.14.3</version></dependency>
如果不能够自动引入，需要手动下载（可以直接百度进行下载），将下载好的jar包存放在项目resource中，修改pom文件如下：
<dependency><groupId>net.sf.jacob-project</groupId><artifactId>jacob</artifactId><version>1.17</version><scope>system</scope><systemPath>${basedir}/src/main/resources/lib/jacob.jar</systemPath></dependency>

使用时直接调用即可，两个参数分别是源文件的绝对地址（包括文件名）和转换后的文件绝对地址（包括文件名）
