背景:
有需求要将原来的Spring(3.2.6) + Springmvc + Hibernate项目重构为Springboot(1.5.2)项目
描述:
记录重构过程,以及期间遇到的种种问题和对应的解决方案
环境:
原项目: win10 + eclipse + jdk1.8 + mysql5.7
新项目: win10 + IDEA + jdk1.8 + mysql5.7 + Maven
过程:
第一步: 新建Maven项目
IDEA: project > New > Module > Maven (选择 maven-archetype-quickstart 快速创建一个maven项目, 如下图)
点击Next, 自己想一个项目的 groupid(一般为项目域名的倒写) 和 artifactid(项目名) 并填好(如下图)
点击Next, 确认创建信息
点击Next, 选择项目创建文件夹地址
点击确认自动创建项目
项目创建就完成了
如果发现创建maven项目十分缓慢, 很可能是由于访问maven官方中央仓库网速太差导致的,建议可以修改Maven的settings.xml文件
将默认的仓库地址改为国内阿里云的地址(http://maven.aliyun.com/nexus/content/groups/public/),(如下图)
第二步: 配置pom.xml
不多说,上代码,如果对其中某些节点含义不清楚, 可以参考此博文: https://www.cnblogs.com/hafiz/p/5360195.html
