Convert the Jar file to the exe installation file, and install the jar file. After checking on the network and using the exe4jtool for real-time conversion, the basic steps of the software are as follows: 1. you need to know whether the target file is 32-bit or 64-bit. If the generated file is 32-bit, you need to use a 32-bit jre. If the generated file is 64-bit, A 64-bit jre is required. Figure 1 Select 3

Multi-thread programming (5) -- thread pool, multi-thread programming -- Thread Pool The Java. util. concurrent package is added after JDK 1.5. This package mainly introduces the use of threads and thread pools in java. It provides great help for us to handle thread issues during development. I.

Now almost all development projects are used by MAVEN projects, but sometimes you can use the diff gate or the new jar may not be able to search the Web in the Pom file configuration should be how to write, so write down this blog.For example, I now want to join the Aaa.jar this package open cmd, enter the command inside MVN install:install-file-dfile= want to add the location of the jar package (such as E:

If there are multiple wars in a TOMCAT when a product is packaged, the general way to deploy it is to deploy to the%tomcat_home%/webapps directory, which follows the Java EE specification and puts the referenced jar into the%tomcat_home%/webapps/ Xxxxx.war/web-inf/lib below. But more than one project could possibly refer to the same jar, how do you make multiple projects share this

in the development process, we often encounter the situation of reading the configuration file, for the configuration file read, depending on the environment and so on, and so on, in general, if the use of relative/path from a non-jar package, relatively simple, it is not a statement, and in manycase, we need to pack our class into a jar file for use, and then we'll find out that if we hadn't taken that int

Thread pool data structure and threading construction methodSince we have seen the Threadpoolexecutor source code, it is easy to see the data structure of the threadpoolexecutor thread pool. Figure 1 depicts this data structure.Figure 1 Threadpoolexecutor data structureIn fact, even without the above figure describing the Threadpoolexecutor data structure, we are able to guess its data structures according

Java thread pool (1), java Thread PoolWhy use a thread pool? 1. reduce resource consumption. Reuse created threads to reduce the consumption caused by thread creation and destruction. Second, increase the response speed. When a task arrives, the task can be executed immediately without waiting for the thread to be created. Third: Improve the manageability of threads. A thread is a scarce resource. If it

destruction are irrelevant to the work originally executed by the creation thread. To improve efficiency, Windows provides the thread pool concept. The thread pool makes it easier to create, manage, and revoke threads. I think the thread pool can be:* Initialize the thread and dynamically create the thread.* Pre-allocated thread

package has far worse functions than log4j and has average performance. Later Apache developed a commons-logging.jar to be compatible with two logger. Therefore, the underlying logger can be switched with the log program written in the commons-logging.jar. You can choose log4j, java. util. logging or its own simple logger. However, I strongly recommend that you use log4j because log4j has high performance and the log output time is almost the same as system. Out. On average, you only need 5 us
