spring boot jar启动
1、依赖包输出
记得禁用热加载
<plugin>

<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<id>copy</id>
<phase>install</phase>
<goals>
<goal>copy-dependencies</goal>
</goals>
<configuration>
<outputDirectory> ${project.build.directory}/dependency </outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
2、启动命令
java -cp
D:\javawork\task\target\classes;D:\javawork\task\target\dependency\* com.qmtt.Application --spring.profiles.active=dev
3、jvm相关参数考
