Detailed tomcat hot deployment and hot loading methods

I often have to change Java/JSP files in the project development process, but I don't want to restart the server (the server takes time to restart), and I want to get (debug) results directly. There are two ways to hot-deploy and hot-load:

1. Hotload: Set reloadable="true" in server.xml-> context property

2. Hot deployment: Set autoDeploy="true" in server.xml-> context property

It is also possible to:

3. Difference:

Hot loading: The server will listen for class file changes, including web-inf/class,wen-inf/lib, web-inf/web.xml and other files. If changes occur, it will load locally without emptying the session and releasing the memory. Development with many, but to consider the case of memory overflow.

Hot Deployment: The entire project is redeployed, including you retyping the.war file. It clears the session and frees up memory. A lot of it is used when the project is packaged.

You can also modify the configuration file above by setting it on Eclipse

Eclipse project name right-click: properties->Tomcat->General->Make this context as loadable (loadable ="true") Do not select Eclipse's project name Right click:Tomcat project->Update Context Definition
