When editing jsp and js files using Eclipse, it often occurs. I have been stuck on Baidu N times online. After N optimization and adjustments, the stuck phenomenon gradually improves. The specific method plays a role, which is not easy to talk about. List all used methods as follows:
1. Cancel verification
windows–>perferences–>validation
Click all except manual, and only classpath dependency Validator is left under build
2. Close spelling check
windows–>perferences–>general–> editors->Text Editors->spelling
3. For MyEclipse, editing tools when modifying JSP pages
Window > perferences > General > Editors > File Associations >
Select *.jsp > Set "MyEclipse JSP Editor" to default in Associated editors.
4. Eliminate jar packages to access the network
When editing JSP with eclipse or myeclipse, using smart prompts may cause ide to get stuck.
This is because when eclipse prompts, the network will be accessed according to the javadoc location specified by the JAR package.
Solution: window-->preferences-->java-->installed JREs, edit the jre, and set the javadoc location of the javadoc to empty (none). Of course, you can also download javadoc to the local machine, and the relevant settings can also be solved.
In addition: deal with all the jar packages used in your project the same way.
5. Modify the shortcut key to open the link
Recently, when editing code in MyEclipse, using shortcut keys for copying and pasting often causes the editor to pause briefly, and the cursor does not follow, and he can't react and he is almost fake.
After thinking about it, it should be caused by the configuration on the editor or the functions of the IDE, so I went to Preferences to find the edit function, conducted one by one, and finally found that it was caused by the hyperlink function of the code.
Enter method: Window -> Preferences -> General -> Editors -> Text Editors -> Hyperlinking
Change the shortcut key of the hyperlink to other keys such as Alt (cannot be changed to shift)
Note: In Eclipse, you can often use Ctrl+mouse to directly guide the editing interface to related methods, properties, or classes.
This function is indeed very useful, but since the copy-paste shortcut key is also Ctrl, Eclipse cannot react when I operate it quickly and cannot analyze my operation. Now I only need to change another shortcut
6. Modify the project's .project file
The default js editor in eclipse is very slow, especially when copying and pasting code.
The official website standard version of eclipse3.9 for javaEE does not install any plug-ins. The card was unbearable when writing JS. I tried to remove all validates, including the menu and project properties, and I had no effect. Later, I found in the project root directory.. project that the following red lines were still there. After deleting all the configuration segments corresponding to red, the problem was solved and editing JS was no longer like a snail.
<buildSpec> <buildCommand> <name></name> <triggers>full,incremental,</triggers> <arguments> <dictionary> <key>LaunchConfigHandle</key> <value><project>/.externalToolBuilders/</value> </dictionary> </arguments> </buildCommand> <buildCommand> <name></name> <arguments> </arguments> </buildCommand> <buildCommand> <name></name> <arguments> </arguments> </buildCommand> <buildCommand> <name></name> <triggers>full,incremental,</triggers> <arguments> <dictionary> <key>LaunchConfigHandle</key> <value><project>/.externalToolBuilders/</value> </dictionary> </arguments> </buildCommand> </buildSpec> <natures> <nature></nature> <nature></nature> <nature></nature> <nature></nature> <nature></nature> </natures>
7. Adjust the Eclipse running memory.
Edit the file in the eclipse installation directory and change the parameters to:
-vmargs -=1.6 -Xms512m -Xmx512m -XX:PermSize=256M -XX:MaxPermSize=256M -XX:-UseGCOverheadLimit
From the above seven aspects, I have summarized the solutions to the jsp and js files stuck when editing Eclipse, and I hope it will be helpful to everyone.
