从零搭建springboot工程

spring boot工程搭建 

第一：从官网创建项目https://start.spring.io

第二：idea导入项目

pom.xml

工程结构

程序入口

log4j2.xml

mybatis-generator.xml

搭建项目遇到问题：

第一个问题：maven mybatis-generator:generate失败 Exception getting JDBC Driver

mybatis-generator运行需要在pom插件引入mysql-connector-java包参考链接https://segmentfault.com/q/1010000011580237/a-1020000011580609

第二个问题：整合log4j2时候报错

SLF4J: Class path contains multiple SLF4J bindings.

SLF4J: Found binding in [jar:file:/Users/zzm/dubbomaven/dubboRepository/ch/qos/logback/logback-classic/1.2.3/logback-classic-1.2.3.jar!/org/slf4j/impl/StaticLoggerBinder.class]

SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.

SLF4J: Actual binding is of type [ch.qos.logback.classic.util.ContextSelectorStaticBinder]
