vscode builds java development environment

Environment: The system needs to install jdk1.8, configure the environment variable JAVA_HOME

Open vscode, install java related plug-ins

Language support for Java ™ for Visual Studio Code

Java Extension Pack

Debugger for Java

Java Test Runner

After the above plug-ins are installed, you can start java development.

Personally recommended plug-in

Eclipse Keymap for Visual Studio Code. (eclipse shortcut keys, favorite of eclipse users)

Lombok Annotations Support for VS Code. (Simplified POJO, very pleasant surprise)

Develop basic configuration

Common configuration items: File->Preferences->Settings

1 , maven configuration (if maven is installed locally)

"java.configuration.maven.userSettings": "/home/luokai/maven/apache-maven-3.3.9/conf/settings.xml"

It is recommended to use maven Ali warehouse: add ## in settings.xml #

<mirrors>
    <mirror>
        <id>alimaven</id>
        <name>aliyun maven</name>
        <url>http://maven.aliyun.com/nexus/content/repositories/central/</url>
        <mirrorOf>central</mirrorOf>
    </mirror>
</mirrors>

2. Global search ignores folders, and you often need to ignore target files when searching for files.

"search.exclude": {
            "**/node_modules": true,
            "**/bower_components": true,
            "**/target": true,
            "**/logs": true
        }

3. Junit testing, there are problems with the Java Test Runner plug-in running multi-module project tests

GitHub issues have now been resolved: ), in version 0.7.1

recommend a cumbersome way: rely on maven

tasks-> configure tasks

in the tasks array Add the following configuration:

"tasks": [
    {
        "label": "test:HelloWorld",
        "type": "shell",
        "command": "mvn -Dtest=HelloWorldTest#testHelloWorld test",
        "group": "test"
    },

Execute test:command: Run the specified unit test, HelloWorldTest.testHelloWorld() method

Task->Run task

Select just added The test case works perfectly.

4. Use tomcat to debug web projects

(1) Install the Tomcat for Java plug-in

(2) Click the right number of TOMCAT SERVERS in the sidebar and select the locally installed tomcat

(3) Select the war package to run.

PS: Pay attention to building the latest war package before debugging

Tips:

Cancel clicking to open the file to cover the navigation bar:

File->Preferences->Settings, add "workbench.editor.enablePreview": false,
