Java的特点有哪些
Java的特点有哪些
1.Java语言作为静态面向对象编程语言的代表，实现了面向对象理论，允许程序员以优雅的思维方式进行复杂的编程。
2.Java具有简单性、面向对象、分布式、安全性、平台独立与可移植性、动态性等特点。
3.使用Java可以编写桌面应用程序、Web应用程序、分布式系统和嵌入式系统应用程序等。
1、openoffice依赖jar，以maven为例：
com.artofsolving
jodconverter
2.2.1
org.openoffice
jurt
3.0.1
org.openoffice
ridl
3.0.1
org.openoffice
juh
3.0.1
org.openoffice
unoil
3.0.1
org.slf4j
slf4j-jdk14
1.4.3
2、直接上转换代码，需要监听openoffice应用程序8100端口即可。
public void convert(File sourceFile, File targetFile) {
try {
// 1: 打开连接
OpenOfficeConnection connection = new SocketOpenOfficeConnection(8100);
connection.connect();
DocumentConverter converter = new OpenOfficeDocumentConverter(connection);
// 2:获取Format
DocumentFormatRegistry factory = new BasicDocumentFormatRegistry();
DocumentFormat inputDocumentFormat = factory
.getFormatByFileExtension(getExtensionName(sourceFile.getAbsolutePath()));
DocumentFormat outputDocumentFormat = factory
.getFormatByFileExtension(getExtensionName(targetFile.getAbsolutePath()));
// 3:执行转换
converter.convert(sourceFile, inputDocumentFormat, targetFile, outputDocumentFormat);
} catch (ConnectException e) {
log.info("文档转换PDF失败");
}
}3、需注意：jodconverter 在转换2007版本以后的xxx.docx文档会报错，原因大家都明03后缀名xxx.doc 07以后版本xxx.docx
查看jodconverter源码发现documentFormat不支持xxx.docx格式BasicDocumentFormatRegistry中public DocumentFormat getFormatByFileExtension(String extension)默认支持是使用doc格式

解决方法：重写BasicDocumentFormatRegistry类中public DocumentFormat getFormatByFileExtension(String extension)方法，只要是后缀名包含doc则使用doc的documentFormat文档格式
