Maven分层的结构体系

  • application 不以骨架方式创建
  • port 不以骨架方式创建
  • domain 不以骨架方式创建
  • resource 必须以骨架创建

父pom.xml

packaging 必须是pom modules里引入各个模块。
可以在properties标签里 引入spring.version mysql.version ….等等

子模块pom如何写

resource 引 application ，application 引 port 和 domain
鉴于解耦思想，resource模块建议只引入application

resource中主类启动配置

@SpringBootApplication(scanBasePackages = {“cc.yybk.*”}) 扫描所有依赖

有个bug类似

笔者创建许多SpringBoot项目 有时候会自动创建一个ServletInitializer的类 但有时候并没有。
这个类有什么用？如果没有这个类，曾经尝试使用Jetty启动服务会报错。大概应该兼容各种web容器吧。
我决定要把这个类保存在这里 。

package cc.yybk.resource;

import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

public class ServletInitializer extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(YybkResourceApplication.class);
    }

}

Maven一些常用的依赖

笔者每次想用到某些依赖，还要到处去翻，太累了。
于是我觉得将一些常用的依赖也记录在这里。
如果是微服务，在最大pom中
这样子在后续的模块组件中就不用担心版本冲突了
