使用EasyCode自定义模板，自动生成代码

首先创建spring boot项目，导入相关依赖是必须的#### 导入依赖：

pom.xml

<?xml version="1.0" encoding="UTF-8"?>

</project>

在application.xml配置数据连接信息

server:
  port: 8081
spring:
  main:
    allow-bean-definition-overriding: true
  datasource:
    username: root
    password: 123456
    url: jdbc:mysql://localhost:3306/tbl?serverTimezone=UTC&userUnicode=true&characterEncoding=utf-8
    driver-class-name: com.mysql.cj.jdbc.Driver
    type: com.alibaba.druid.pool.DruidDataSource

mybatis:
  type-aliases-package: com.test.easycodeauto.domain
  mapper-locations: classpath:mapper/*.xml

模板分享

先说一下模板在哪里配，它的位置是设置到其他设置到EasyCode

然后点开EasyCode，在这里分别设置，把我的模板分别粘贴复制进去即可，没有同名的就点加号创造同名文件。
