spring boot web 多模塊打包

 新建一個maven-web項目，取名web-all，web-all項目使用了themeleaf模板引擎

再依次建立以下子模塊

common模塊:公共模塊，會被其他模塊引用api

web模塊:web應用，將會用來部署網站,會引用common模塊

模塊如圖

要打成獨立部署的jar模塊的話,pom文件裏要加入 spring-boot-maven-plugin插件,parent的pom不需要加build 插件。最後在web-all根目錄執行mvn clean package命令即可。然後到web文件夾的target目錄找到spring-boot-web.jar，直接執行java -jar spring-boot-web.jar。
