IDE idea automatic compilation and configuration of on update action and on frame deactivation

On Upate Action And On Frame Deactivation The setting of these two options , Depend on How the project is deployed yes exploded .

1、On Update action The meaning of

First of all to see On Update action Related explanation , Literally , Namely Manual trigger update When you move What do you do .

As shown in the figure above , Yes 4 An option .

1、Update resources ---- Update static resources , such as html,js,css etc. Both run mode and debug mode take effect immediately .
2、Update classes and resources ---- to update java,jsp and Static resources .

• java After modification , Will be compiled into .class Then overlay to target/kao Under the folder ,IDE In debug mode , Immediate effect .IDE In operation mode , Not effective immediately , need redeployed It will take effect. .
• jsp After modification , When interviewed again , It will update automatically , Recompile to .java---->.class Save in t omcat Of work Under the table of contents . Since it is only during access that it is detected whether to modify , Need to recompile , therefore IDE Operation mode and IDE In debug mode , All effective immediately . Refresh the next page ）;

3、Redeployed ----- Redeployment , Publish to tomcat in , No restart tomcat, Instead, delete the original , And then redistribute ;
4、Restart server ----- restart tomcat

2、On frame deactivation The meaning of

Look again. On frame deactivation , intend IDE When inactivated What do you do , That is to say IDE When you lose focus What do you do .

Yes 3 An option ：

• Do nothing --------- Don't do anything?
• Update resources ---- Update static resources , such as html,js,css etc. Both run mode and debug mode take effect immediately .
• Update classes and resources ---- to update java,jsp And static resources ditto .

3、 test On Update Action

Static resources don't need to be tested .
test On Update Action Of update classes and resources Options stay debug Pattern And Operation mode The difference between the two .

3.1、 On Update Action Operation mode

Operation mode Next ,jsp yes update classes and resources It's immediate , however .java After document modification It will not take effect immediately . As shown in the figure below .

3.2、 On Update Action debug Debug mode

debug Debug mode Next ,jsp and java File modification Will take effect immediately . As shown in the figure below .

4、 test On frame deactivation

test On frame deactivation , namely IDE Do something automatically when you lose focus , We test update classes and resources Options , Let's say Debug mode For example , Operation mode except java The modification will not take effect automatically , Others are consistent .

5、 summary

Officially recommended configuration , As shown in the figure below ：

On Update action choice update classes and resources Option ,
When in debug Pattern Next （java、jsp all Immediate effect ）
When in Operation mode Next （jsp Immediate effect ,java need redeploy It will take effect. ） .

On frame deactivation , When IDE When you lose focus Automatic triggering , And in the development process You may need to query information or Chat with people Or do something else ,IDE Need to keep losing focus . Every time you lose focus, it automatically triggers update ,CPU once It costs a lot , The computer slows down in an instant , So there's no need to , Set to Do nothing best , The official default is Do nothing .

The configuration I recommend , As shown in the figure below ：

such , Static files are automatically updated , The system does not need to be restarted . java Files need to be updated manually . It's a compromise .
