summary

Intellij IDEA The more you use it, the more powerful it is , It's always when we write code , Give us a little surprise from time to time . for Intellij IDEA The love of , I decided to write a column or series about it , Put some good ones Intellij IDEA Tips to share . This is the first article in this series , It mainly introduces some practical tips that you may not know .

My favorite 【 Performance mode 】

We can use 【Presentation Mode】, take IDEA Get the biggest , You can only focus on the code in one class , To carry on without interference coding.

have access to Alt+V Shortcut key , eject View View , And then choose Enter Presentation Mode. The effect is as follows :

The advantage of this model is , Can make you more focused , Because you can only see the code for a specific class . Maybe the reader will ask , After entering this mode , I want to see what to do with other classes of code ? This is the time , It's about to test your keyboard proficiency . You can use CTRL+E Pop up recently used files . Or use CTRL+N and CTRL+SHIFT+N Location file .

How to exit this mode ? It's simple , Use ALT+V eject view View , And then choose Exit Presentation Mode  that will do . But I strongly advise you not to , Because you can be in Enter Presentation Mode In mode IDEA Do anything in it . Of course, the premise is , You are right about IDEA Proficient enough .

magical Inject language

If you use IDEA Writing JSON String time , Then one by one \ To escape double quotes , It's really not right , It's annoying and easy to make mistakes . stay IDEA have access to Inject language Help us automatically escape double quotes .

First, focus on the double quotes , Use alt+enter The shortcut key pops up inject language View , And select Inject language or reference.

After selection , Bear in mind , Press... Directly enter Enter key , To pop up inject language list . Choose... From the list  json Components .

After the choice . Mouse focus will be automatically positioned in double quotes , This time you use alt+enter You can see that

Choose Edit JSON Fragment And return , You can see the editor JSON View of the file .

You can see IDEA It does help us automatically escape double quotes . If you want to quit editing JSON View of information , Just use ctrl+F4 The shortcut key can .

Inject language There are so many languages and operations that you can't imagine , Readers can do their own research on .

Use the shortcut key to move the split line

Suppose you have the following scenario , The name of a class is in project Part of the view is blocked .

You want to see the name of the class completely , What to do . Generally use the mouse to move the split line , But it's too inefficient . have access to alt+1 Focus your mouse on project In the view , Then use it directly ctrl+shift+ Left and right arrows To move the split line .

ctrl+shift+enter It's not just for a semicolon at the end of a line

ctrl+shift+enter In fact, it means Finish for you It means , Not just for semicolons . for instance :

This code , We also need to if Statements with braces can be compiled through , At this time, you directly input ctrl+shift+enter,IDEA It will automatically help you finish , With braces .

Don't use it all the time IDEA Refactoring function of

IDEA The refactoring function of is very powerful , But sometimes , In a single class , If you just want to batch modify a certain text , You don't have to use refactoring . for instance :

In the above code , Yes 5 A place used rabbitTemplate Text , How to modify in batch ? The first is to use ctrl+w Choose rabbitTemplate This text , Then use... In turn 5 Time alt+j Shortcut key , Select... One by one , So all five texts are selected and highlighted , At this time, you can directly batch modify .

Remove the navigation bar

Remove the navigation bar , Because I don't usually use much .

You can remove the red navigation bar , Give Way IDEA It's a little cleaner . Use alt+v, Then remove the Navigation bar that will do . After removing the navigation bar , If you still use it occasionally , Direct use alt+home You can temporarily display the navigation bar .

If you want this temporary navigation bar to disappear , Use it directly esc The shortcut key can .

Position the mouse on project In the view

When there are so many packages and classes in the project , Sometimes we want to know that the current class is project Where is the view located .

In the picture above DemoIDEA in , How do you know it's in spring-cloud-config Where in the project ? You can use it first alt+F1, eject Select in View , And then choose Project View Medium Project, enter , You can immediately locate the class .

Picture description here

Then how to project Jump back to the code ? You can use it directly esc sign out project View , Or use it directly F4, Jump into the code .

Powerful symbol

If you vaguely remember a method name with a few letters , Want to be in IDEA Find it out , What can I do ? Use it directly ctrl+shift+alt+n, Use symbol To find out . for instance :

You want to find checkUser Method . Direct input user that will do .

If you remember a method in a business class , You can also use the initial to find the class , Then add a ., It's OK to type the method name again .

How to find a directory

Use ctrl+shift+n after , Use /, Then enter the directory name .

Automatic generation not null Judgment statement

Automatic generation not null such if Judge , stay IDEA There are many ways , One way you may not have thought of .

When we use rabbitTemplate. after , Direct input notnull And return ,IDEA So that it can automatically generate if Determine the .

Follow the template to find the content

This is also a function I like very much , You can find the code block matching the template according to the template . for instance :

Want to find everything in the whole project try catch sentence , however catch There is no exception handling in the statement .

catch The statement does not handle exceptions , It's extremely dangerous . We can IDEA It's easy to find all this code .

use first ctrl+shift+A The shortcut key pops up action box , Then input Search Struct

choice Search Structurally after , enter , Jump to template view .

Click on Existing Templates Button , choice try Templates . In order to find out catch There is no code block to handle exceptions , We need to configure it CatchStatement Of Maximum count Value , Set it to 1.

Click on Edit Variables Button , Modify... In the interface Maximum count Value .

Finally, click find Button , You can find out catch There is no code to handle exceptions .
