环境配置

1. 临时切换 Java 版本（仅当前终端生效）

在终端中直接执行以下命令，将当前终端的 JAVA_HOME 指向 Java 17：

bash

复制代码

export JAVA_HOME=/Library/Java/JavaVirtualMachines/amazon-corretto-17.jdk/Contents/Home

执行后验证是否切换成功：

java -version

2. 永久切换 Java 版本（所有终端生效）

为了让所有终端都默认使用 Java 17，需要配置终端的环境变量：

打开终端配置文件（根据你使用的终端，选择对应的文件）：
- 若使用 zsh（默认终端）：
  
  bash
  复制代码
```
open ~/.zshrc
```
- 若使用 bash：
  
  bash
  复制代码
```
open ~/.bash_profile
```

在文件末尾添加以下内容（指定 Java 17 的路径）：

bash

复制代码

# 设置默认 Java 版本为 Java 17
export JAVA_HOME=/Library/Java/JavaVirtualMachines/amazon-corretto-17.jdk/Contents/Home

保存文件并生效配置：

bash
复制代码
```
source ~/.zshrc  # 或 source ~/.bash_profile
```
验证配置：

java -version
