java 使用POI导出为pdf，通过浏览器直接下载

pom.xmlo依赖：

<!--POI Excel表格导出依赖-->
<dependency><groupId>org.apache.poi</groupId><artifactId>poi-ooxml</artifactId><version>3.17</version>
</dependency><!-- 导出PDF使用 -->
<dependency><groupId>com.itextpdf</groupId><artifactId>itext-asian</artifactId><version>5.2.0</version>
</dependency>
<dependency><groupId>com.itextpdf</groupId><artifactId>itextpdf</artifactId><version>5.4.3</version>

因项目原因就不展示效果图了，可自己添加静态数据查看，直接上代码，根据自己需求修改：
