jsvc

Jsvc uses 3 processes:

1. a launcher process

2. a controller process

3. a controlled process.

   The controlled process is also the main java thread, if the JVM crashes the controller will restart it in the next minute.

Jsvc is a daemon process so it should be started as root and the -user parameter allows to downgrade to an unprivilegded user.

When the -wait parameter is used, the launcher process waits until the controller says "I am ready", otherwise it returns after creating the controller process.

Spring Boot Maven plugin

Spring Boot Maven plugin的5个Goals

1. spring-boot:repackage 在mvn package之后，再次打包可执行的jar/war，同时保留mvn package生成的jar/war为.origin
2. spring-boot:run 运行Spring Boot应用
3. spring-boot:start 在mvn integration-test阶段，进行Spring Boot应用生命周期的管理
4. spring-boot:stop 在mvn integration-test阶段，进行Spring Boot应用生命周期的管理
5. spring-boot:build-info 生成Actuator使用的构建信息文件build-info.properties
