java 应用中使用 jodconvert

版本: 4.2.0

示例代码:

File inputFile = new File("document.doc");
File outputFile = new File("document.pdf");

// Create an office manager using the default configuration.
// The default port is 2002. Note that when an office manager
// is installed, it will be the one used by default when
// a converter is created.
final LocalOfficeManager officeManager = LocalOfficeManager.install(); 
try {

    // Start an office process and connect to the started instance (on port 2002).
    officeManager.start();

    // Convert
    JodConverter
             .convert(inputFile)
             .to(outputFile)
             .execute();
} finally {
    // Stop the office process
    OfficeUtils.stopQuietly(officeManager);
}

如果要转换其他格式, 只需要修改文件, 会根据文件后缀自动匹配:

File inputFile = new File("spreadsheet.xls");
File outputFile = new File("spreadsheet.ods");
JodConverter
         .convert(inputFile)
         .to(outputFile)
         .execute();

当使用stream流时,可以显示指定其格式:

InputStream inputStream = ...
OutputStream outputStream = ...
JodConverter
         .convert(inputStream)
         .as(DefaultDocumentFormatRegistry.XLS)
         .to(outputStream)
         .as(DefaultDocumentFormatRegistry.ODS)
         .execute();

问题: 每次使用都启动officeManager , 性能太低 .

在大多数应用中, 只需要启动一个OfficeManager , (如在servlet listener , spring context 配置时) , 当应用停止时,停止之. OfficeManager 自己会处理多线程.
