using Java code to fetch C # applications and implement data interaction This article mainly introduces applications that call C # through Java and passes parameters to C # clients. Before doing the project encountered this function, by the way to share the code out; Requi

easily accessible to the current thread instance, it is threadlocal.Three: Threadlocal's application scenarioThreadlocal has such scenarios as connection pooling management, session management, and so on.In the management of the connection pool, when we need to get a connection, we should give a different connection for each fetch. In a Web application, a request is managed by a thread pool, which means that the behavior of getting a connection is not a single-threaded behavior, so we'd better

end, such as the following code.Attention:In practice, if the Linux command fails on a Linux server, such as the not found command, it is executed, and the code will continue to go down. So make sure the command is correct, or use the return value to judge! The return and not called return values of the call WAITFOR () are different types.Such a download method can only rely on the download to the local MAVEN configuration of the warehouse, if there

Although there are already two standard parsing methods for DOM and sax in Java But it is not easy to operate, for a beginner like me, part of the code is living nausea To this end, the great third party development team developed jdom and DOM4J tools Given the current trend, we are here to talk about the basic usage of dom4j, not involving complex operations such as recursion. DOM4J is a lot of use, th

Sometimes, you need to do the file compression, decompression.Java itself provides a compressed, uncompressed native class library. But with open source code, I generally choose to use the Open source class library.Here's a sticker, I use ant-1.6.5 zip compression, unzip the code bar.Ziputil.javaImport Java.io.file;import java.io.fileinputstream;import java.io.fileoutputstream;import java.io.IOException; Im
