Office转换pdf解决并发问题
由于项目之前的代码 https://blog.csdn.net/Amor_Leo/article/details/89389321
不能支持并发 于是用了锁机制和阻塞队列实现
方法 一 :
@Component
public class Office2PDFUtils {
private static Logger logger = LoggerFactory.getLogger(Office2PDFUtils.class);
@Value("${oppenOffice.winPath}")
private String winPath;
@Value("${oppenOffice.linuxPath}")
private String linuxPath;
@Value("${oppenOffice.port}")
private String port;
private static BlockingQueue<OfficeManager> OfficeManagerQueue = new LinkedBlockingDeque<>();
private static Lock lock = new ReentrantLock();
/** * @Description: 使Office2003-2007全部格式的文档(.doc|.docx|.xls|.xlsx|.ppt|.pptx) 转化为pdf文件 * @method: openOfficeToPDF * @Param: inputFilePath * @Param: outputFilePath * @return: boolean * @auther: LHL */

}
/** * @Description: 在bean创建实例时, 连接OpenOffice.org 并且启动OpenOffice.org * @method: initOpenOfficeService * @Param: * @return: void * @auther: LHL */

// 锁
