Springboot2.0 + Mybatis组合搭建

springBoot 选择2.0版本

1、访问 http://start.spring.io/

打包下载，用maven 导入下载的项目 

开发工具：Eclipse  Neon.1a Release (4.6.1)
jdk：1.8.0_152
maven:4.0.0

  增加 两个插件

  PageHelper 分页插件

  mybatis generator 自动生成代码插件

查看一下pom.xml  增加一些依赖包名

用更简洁的application.yml文件 将原有的resource文件夹下的application.properties文件删除，创建一个新的application.yml配置文件， 文件的内容如下：

server:
  port: 8080


spring:
    datasource:
        name: test
        url: jdbc:mysql://127.0.0.1:3306/Test
        username: root
        password: root
        # 使用druid数据源
        type: com.alibaba.druid.pool.DruidDataSource
        driver-class-name: com.mysql.jdbc.Driver
        filters: stat
        maxActive: 20
        initialSize: 1
        maxWait: 60000
        minIdle: 1
        timeBetweenEvictionRunsMillis: 60000
        minEvictableIdleTimeMillis: 300000
        validationQuery: select 'x'
        testWhileIdle: true
        testOnBorrow: false
        testOnReturn: false
        poolPreparedStatements: true
        maxOpenPreparedStatements: 20
mybatis:
  mapper-locations: classpath:mapping/*.xml
  type-aliases-package: com.winter.model


#pagehelper分页插件
pagehelper:
    helperDialect: mysql
    reasonable: true
    supportMethodsArguments: true
    params: count=countSql

generator 文件下新建  generatorConfig.xml  自动生成代码 

配置pom.xml中generator 插件所对应的配置文件 ${basedir}/src/main/resources/generator/generatorConfig.xml
