Myeclipse optimization skills

Myeclipse optimization skills Step 1: Cancel automatic validation

There are a bunch of validation items, such as XML, JSP, JSF, and JS. We don't have to perform automatic verification on all of them, but we only need to manually verify them when necessary!

Cancellation Method:
Windows-> perferences-> myeclipse-> Validation
Except for all the check boxes under manual, none of them are selected.
Manual verification method:
On the file to be verified, right-click and choose myeclipse> RUN validation.

Step 2: cancel the eclipse spelling check

1. spelling check will cause us a lot of trouble. Our method names will all be abbreviations of words, and he will also prompt errors, so it is best to remove them, so it is not very useful.

Windows> perferences> General> Validation> editors> text editors> spelling

Step 3: cancel the startup items of myeclipse

Myeclipse has many startup items, but many of them are not needed, or only one or two of them can be used.

Windows-> perferences-> General-> startup and Shutdown

Step 4: Change the default JSP Open Mode

After myeclipse is installed, edit the JSP page to open its editing page and preview the page, which is slow and not suitable for development. So change it

Windows> perferences> General> editors> File Associations

Select an editor below and click the default button on the left.

Step 5: change the code prompt shortcut key

The current Code prompts the shortcut key. The default value is Ctrl + space, and we also switch the input method, so there will be conflicts. Who is myeclipse made by foreigners .. You do not need to switch the input method.

Windows> perferences> General> keys

Change content assist to Alt +/

At the same time, because Alt +/has been occupied by word completion, you must modify the shortcut key value of word completion at the same time.

Now, is the speed and convenience improved.

Of course, this is just a familiarity with a tool, and there is no technical content, but it is not a saying

With a convenient tool, we can still improve our mood when writing code...

Optimize myeclipse (latest supplement)

Supplement: We recommend that you use Windows> perferences> JAVA> editor> content assist and enter ". ABC "(for Versions later than 7.0, enter. abcdefghijklmnopqrstuvwxyz, the following steps are not required),-> apply-> OK. File-> export-> General-> perferences-> next, select the Save path, and click Finish. open the saved file and search for ". ABC, and then change it to ". abcdefghijklmnopqrstuvwxyz ", save. Then file-> impOrt-> perferences, select the file and finish.After the configuration is complete, you can check the effect when writing the Java program. 1. Remove unnecessary modules

20% of a system's functions often meet 80% of the requirements, and myeclipse is no exception. We only need 20% of the system functions in most cases, so we can disable loading and starting some unused modules. Open the Configuration window through windows-preferences, and select general-startup and shutdown on the left. The module loaded at eclipse startup is displayed on the right, you can remove some modules according to your actual situation.

Windows-> perferences-> General-> startup and Shutdown

Disable useless startup items:

WTP: similar to myeclipse, the main difference is that WTP is free of charge. If myeclipse is used, this can be canceled.
Mylyn: A team task management tool, similar to CVS, which manages the project progress in task units and can be canceled if it is useless.
Derby: a database saved as a jar. It is useless and canceled.
A large batch of startup items starting with myeclipse easie: the servers supported by myeclipse are only used by myself, and other items are canceled. For example, I only select atat6.x

2. Cancel the project configuration file automatically verified by myeclipse at startup.

By default, myeclipse automatically verifies the configuration file of each project at startup, which is a very time-consuming process,
You can select myeclipse enterprise workbench-validation in the preferences window, and then retain only the manual items in the validator list on the right (select all manual and only the first item in bulid ).

If you only need to select the file for verification, right-click and choose myeclipse-run validation.

Windows-> perferences-> myeclipse-> Validation
Drop all vertices except manual. Only classpath dependency validator is left in build.

Manual verification method:

On the file to be verified, right-click and choose myeclipse> RUN validation.

3. Remove the spelling check (if you think it is useful, do not go)

Spelling check will cause us a lot of trouble. Our method names will all be abbreviations of words, and he will also prompt errors, so it is best to remove them, so it is not very useful:
Windows> perferences> General> Validation> editors> text editors> spelling

The default JSP editor opened by myeclipse is not good. The preview will be opened at the same time.
Windows-> perferences-> General-> editors-> file associations,

Change the default value to myeclipse JSP Editor ()
The original default JSP editor is myeclipse visual JSP designer. As the name suggests, this compiler is a JSP visual editor, which is of great help to beginners,
However, modifying the default editor can actually increase the startup speed)

4. Disable Automatic Updates.

For myeclipse7.5:

(1) Disable Automatic Maven update:

Window-preferences-myeclipse enterprise Workbench-Maven4MyEclipse-Maven,
Disable all the options starting with download and update (remove the preceding check box)

(2) Disable update scheduling: window-> preferences-> General-> startup and shutdown-> Automatic Updates schedes (remove the preceding check box)

(3) window-> preferences-> myeclipse dashboard, disable show ...... On start

5. Increase Non-heap memory of JVM

Open myeclipse. ini
-Startup
../Common \ plugins \ org. Eclipse. Equinox. launcher_1.0.101.r34x_v20081125.jar
-- Launcher. Library
../Common \ plugins \ org. Eclipse. Equinox. launcher. win32.win32. x86_1.0.101.r34x_v20080731

-Clean
-Configuration
Configuration
-VM
C: \ Users \ Lenovo \ appdata \ Local \ genuitec \ common \ binary \ com. Sun. java. JDK. win32.x86 _ 1.6.0.013 \ JRE \ bin \ Client \ JVM. dll

-Vmargs
-Xmx384m
-XX: maxpermsize = 384 m
-XX: reservedcodecachesize = 96 m

The above is my myeclipse. ini and needs to be modified to-xmx,-XX: maxpermsize,-XX: reservedcodecachesize,
Increase the values of the three items, but the larger the value is not the better. I used to perform tests under the same conditions (2 GB memory),-xmx,-XX: the value of maxpermsize is 384m, which is faster than that of 512m (depending on the computer ),

-Xmx,-XX: the value of maxpermsize is set to the same size and the sum of the two cannot exceed the memory size of your computer.

6. Window-preferences-myeclipse enterprise Workbench-Maven4MyEclipse-Maven, change Maven JDK to JDK installed on the computer, that is, do not use the JDK improved by myeclipse

Register the Add button and select JDK on your computer (Note: It is not JRE, and my value is java6.014)

7. Window-preferences-myeclipse enterprise Workbench-Matisse4Myeclipse/swing, change design-time information (Dt. Jar) location to the computer-installed JDK's DT. Jar

(That is, do not use the DT. Jar provided by myeclipse. My value is: C: \ java6.014 \ Lib \ DT. Jar)

Appendix: basic configuration of myeclipse:

1. Install myeclipse first, and install myeclipse7.5 requires a VPN proxy. The installation process lasts for about 10-15 minutes. Use the VPN test account.

2. Configure myeclipse,
Choose windows --> preferences from the menu bar"

3. Configure JDK first,
Select "Java --> installed jres" in the left column ",
Click "add" to add

4. In the "add JRE" dialog box that appears, select the JRE directory,
Select the JDK directory where you are located. my options are c: \ Program Files \ Java \ jre6.
In the JRE name column, fill in the name you want. Here is "hijackson's JRE ",
Then "OK" to confirm

5. Return to the settings box and select the configured JRE.

6. Set Tomcat server to available and set the tomcat installation directory

7. Select the configured JDK from the Tomcat JDK.

8. The configuration is complete. You can start the service in three places ~~~

After the above optimization, the startup time of myeclipse can be reduced by 2/3, And the startup speed of Tomcat can be reduced by 1/2 (depending on the situation ),

In particular, the optimization effects of item 6 and item 7 are the most obvious,

If only the first five items are performed, the optimization effect is limited. In the short term, the startup speed can be improved, but it will be slow after about half a month (the specific reason is unknown)

In addition, after using myeclipse for a period of time, many projects will be generated. Even if these projects are closed, myecliose will load these projects at startup, which will take a lot of time, therefore, we recommend that you delete all unused projects and use imp again.ORT.
