启动服务

java版本确认

# 确认java版本为152版本
java -version

启动java服务

java -Xbootclasspath/p:ALPN的jar包路径 -jar app.jar

idea开发相关配置

1. 变更系统环境变量中JAVA_HOME的目标路径为152版本

2. idea版本变更

修改项目设置

将项目sdk切换为152版本

将模块下所有模块依次变更为152版本

打开setting,将maven的jdk设定为152版本

服务配置变更,点击edit configurations菜单

在vm options输入框中,输入

-Xbootclasspath/p:ALPN的jar包路径
