安装JDK

• 安装地址
  JDK1.8
  JDK11
  JDK17

kona jdk

sudo tar -zxvf TencentKona-17.0.6.b1-jdk_linux-aarch64.tar.gz -C /Library/Java/JavaVirtualMachines/kona-jdk-17/
sudo tar -zxvf TencentKona-11.0.14.b1-jdk_linux-aarch64.tar.gz -C /Library/Java/JavaVirtualMachines/kona-jdk-11/
sudo tar -zxvf TencentKona8.0.9.b1_jdk_linux-aarch64_8u322.tar.gz -C /Library/Java/JavaVirtualMachines/kona-jdk-8/ 

设置环境变量

• 设置不同版本的JAVA_HOME

# java
export JAVA_8_HOME=/Library/Java/JavaVirtualMachines/jdk-1.8.jdk/Contents/Home
export JAVA_11_HOME=/Library/Java/JavaVirtualMachines/jdk-11.jdk/Contents/Home
export JAVA_17_HOME=/Library/Java/JavaVirtualMachines/jdk-17.jdk/Contents/Home
PATH=$JAVA_HOME/bin:$PATH
CLASSPATH=.:${JAVA_HOME}/lib
# 设置默认版本
export JAVA_HOME=$JAVA_17_HOME
# alias命令动态切换JDK版本
alias jdk8="export JAVA_HOME=${JAVA_8_HOME}"
alias jdk11="export JAVA_HOME=${JAVA_11_HOME}"
alias jdk17="export JAVA_HOME=${JAVA_17_HOME}"
export PATH
export CLASSPATH

• 生效配置

使用本地的shell配置，这里使用的是zsh

source .zshrc

IDE支持多版本编译

IDEA配置环境变量

pom文件示例

• JDK8

  <properties>
    <jdk.home>${env.JAVA_8_HOME}</jdk.home>
    <jdk.version>1.8</jdk.version>
  </properties>
<build>
    <plugins>
      <plugin>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>${plugin.compiler.version}</version>
        <configuration>
          <source>${jdk.version}</source>
          <target>${jdk.version}</target>
          <fork>true</fork>
          <debug>true</debug>

          <executable>${jdk.home}/bin/javac</executable>
        </configuration>
      </plugin>
  </plugins>
</build>

• JDK17

SpringBoot3要求JDK17，就涉及到此场景

<properties>
    <spring.cloud.version>2022.0.5</spring.cloud.version>
    <slf4j.vesion>1.7.30</slf4j.vesion>
    <jdk.home>${env.JAVA_17_HOME}</jdk.home>
    <spring.boot.version>3.1.7</spring.boot.version>
    <jdk.version>17</jdk.version>
  </properties>
<build>
    <plugins>
      <plugin>
        <artifactId>maven-jar-plugin</artifactId>
        <configuration>
          <archive>
            <manifestEntries>
              <Plugin-Id>${project.artifactId}</Plugin-Id>
              <Plugin-Compiler-Version>${jdk.version}</Plugin-Compiler-Version>
              <Plugin-Open-Modules>java.lang,java.lang.reflect</Plugin-Open-Modules>
            </manifestEntries>
          </archive>
        </configuration>
      </plugin>
  </plugins>
</build>
