我需要将OpenDocument电子表格("~/orders/orderAction.aspx?orderID={0}"
)转换为Excel兼容文件(.ods
或.xls
)
我知道它可能using libreoffice
cli。我想用Java做这件事。我知道Java可以运行命令行进程,但我更喜欢仅JVM解决方案(不需要环境上的libreoffice)。有没有可以提供帮助的开源库?

我最后打电话给libreoffice。
File outputDirectory = source.getParentFile();
String[] command = {
"/usr/bin/libreoffice",
"--headless",
"--invisible",
"-env:UserInstallation=file://" + SystemUtils.getJavaIoTmpDir().getAbsolutePath(), // prevent conversion to fail or just do nothing if libreoffice is already running
"--convert-to",
"ods",
"--outdir",
outputDirectory,
source.getAbsolutePath()
};
try {
ProcessBuilder processBuilder = new ProcessBuilder(command);
processBuilder.directory(outputDirectory);
Process process = processBuilder.start();
int returnValue = process.waitFor();
if (returnValue == 0) {
log.debug("process ended successfully");
} else {
log.error("process ended with error code " + returnValue);
}
} catch (IOException e) {
throw new UncheckedIOException("cannot convert " + source, e);
}
