<?xml version= "1.0" encoding= "utf-8" ?> <!doctype configuration public "-//mybatis.org//dtd config 3.0//en" "http://mybatis.org/dtd/mybatis-3-config.dtd" > <configuration> <!-- 配置全局属性 --> <settings> <!-- 使用jdbc的getgeneratedkeys获取主键 --> <setting name= "usegeneratedkeys" value= "true" /> <!-- 使用别名替换列名, 默认ture --> <setting name= "usecolumnlabel" value= "true" /> <!-- 开启驼峰命名转换 --> <setting name= "mapunderscoretocamelcase" value= "true" /> </settings> </configuration> |
第三步:添加spring配置文件
在resources/spring目录下新建二个文件:
│ └── spring
│ ├── spring-mybatis.xml
│ ├── spring-service.xml
│ └── spring-mvc.xml
spring-mvc.xml

第四步:添加logback配置文件
logback配置比log4j要简单点,功能类似
├── resources
│ ├── logback.xml
在resources文件夹下新建文件:logback.xml
