Spring Java-based container configuration Over the years, a large number of XML configurations and complex dependency management in Spring have been criticized. To implement XML-free development experience, Spring adds new Configuration annotations to support the Java Config

Spring MVC: Java template engine Thymeleaf (2) This article was originally designed to directly introduce Thymeleaf's view parsing, but considering the convenience of learning, we decided to build a spring-mvc first. All the following processes require only one notepad and JDK. Step 1: Use maven to build a web app. mvn archetype:generate -DgroupId=org.nwpu.chen

Sometimes ourProgramYou need to connect to the server to detect the new version. If you find the new version, you need to automatically download and upgrade it. But in windows, how can I replace a running program file?Of course there is a way, the steps are as follows: 1. Package and release our program using Java program proxy (here we need to use its advanced version instead of the free version, click to

Spring is a bad thing and you have to configure everything. But it is also based on the configuration + annotation way, so that we are separated from the constant to new objects of the abyss of misery.My cache is not going to use concurrentmapcache, so I'll just take ehcache as an e
