Springboot和mybatis的整合

创建一个springboot项目，然后添加依赖，pom.xml如下

pom.xml

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

然后配置各种属性

application.yml

 1 server:
 2   port: 8080

 4 spring:
 5     datasource:

23         testOnReturn: false
24         poolPreparedStatements: true
25         maxOpenPreparedStatements: 20
26 mybatis:
27   mapper-locations: classpath:mapping/*.xml
28   type-aliases-package: com.lvpeilei.model
29 
30 #pagehelper分页插件
31 pagehelper:
32     helperDialect: mysql
33     reasonable: true
34     supportMethodsArguments: true
35     params: count=countSql

自动生成代码工具的相关配置
