如果仅更改JSP，是否可以避免在WebLogic中重新部署项目？

Question

I have a project that runs inside the WebLogic server. 80 % of changes I do to the code affect JSP files only (not the class files). Those JSP files contain the frontend logic.

Whenever I change the JSP page, I need to do the following steps to see my changes:

1. mvn install inside the source directory.
2. Redeploy the application in WebLogic Admin Console ("Deployments", "Update").

Is it possible to avoid these two steps, if the only thing I change are JSP files (I don't touch Java files therefore, no class files are modified)?

Note that the application in question is set up in WebLogic so that it reads the directory with the class files ( myProject/target ), not a WAR file.

I have no definite information whether or not JRebel supports WebLogic. Its only alternative known to me, DCEVM , does not support WebLogic according to the last statement here .

Update 1 (02.05.2018 15:23 MSK): Changing

    <wls:resource-reload-check-secs>-1</wls:resource-reload-check-secs>

to

    <wls:resource-reload-check-secs>1</wls:resource-reload-check-secs>

in myProject/src/main/webapp/WEB-INF/weblogic.xml didn't help. When I deploy the application, then make a change to a JSP file, then run mvn install , the changes do not take effect.

Answer 1

There is page-check-seconds properties in weblogic.xml (beside others). Take a look at "weblogic.xml"

Answer 2

如果您以开发人员模式运行，并且每次在源代码上更改jsp时都不会重新部署产品，

Answer 3

No, for several reasons. JSPs have to be compiled . They are not simple html pages. They are also cached by the server. You most definitely have to redeploy the project.
