Java -- spring boot hot deployment and spring boot hot deployment

Java -- spring boot hot deployment and spring boot hot deployment

1. Use the JVM parameter-javaagent :. /lib/springloaded-1.2.6.RELEASE.jar-noverify, can achieve hot deployment, but with idea students a bit pitfall, must be manually compiled, because the detection is in the target directory classes

 

2. By adding a dependency to pom, you can directly perform hot restart (faster than restarting, only restarting part of the dependency)

<! -- Automatic hot start: restarts immediately after the class is detected to be re-compiled --> <dependency> <groupId> org. springframework. boot </groupId> <artifactId> spring-boot-devtools </artifactId> <optional> true </optional> </dependency>
