Mybatis的应用1 Mybatis和logback的应用配置

首先新建一个module, 然后，在pom文件里面添加一些引用的项。

pom.xml

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

</project>

在resourses下面新建一个application.yml文件

application.yml

server:
  port: 8888   # 配置端口号

logging:
  path: logs   #在同级目录下生成logs文件夹
  file: mylog.log  # 生成文件

spring:   #spring里面配置mysql地址之类的
  application:
    name: myTest   #仅仅是application名字
  datasource:  #mysql的配置
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://127.0.0.1:3306/course    #本地的地址➕端口号➕数据库名称
    username: root   #数据库用户名和密码
    password: 123456Aa

mybatis:
  type-alises-package: com.course.model  #javabean，做映射的
  mapper-locations:
    - mapper/*    #文件夹mapper  加载下面的所有xml文件

logback.xml文件

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