          class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource" />
    </bean>

</beans>

mybatis-config.xml:

主要用於配置 駝峯命名法，實體類簡稱等。html

本人不習慣用，是在mybatis.xml中用的 resultType="實體類包名"java

例如：mysql

resultType="com.company.entity.Orders"
<?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>

   <settings>
         <setting name="jdbcTypeForNull" value="NULL" />
         <setting name="useGeneratedKeys" value="true"/>
           <setting name="useColumnLabel" value="true"/>
           <!--開啓駝峯命名轉換  table(create_time)->po(createtime) -->
           <!--<setting name="mapUnderscoreToCamelCase" value="true"/>-->
   </settings>
   <!-- 實體類,簡稱 -設置別名 -->
   <!--<typeAliases>-->
      <!--<typeAlias alias="user" type="org.nessary.user.admin.entity.User" />-->
   <!--</typeAliases>-->

</configuration>

日誌 配置：log4j.properties:

#定義LOG輸出級別
log4j.rootLogger=INFO,Console,File  
#定義日誌輸出目的地爲控制檯
log4j.appender.Console=org.apache.log4j.ConsoleAppender  
log4j.appender.Console.Target=System.out  
#能夠靈活地指定日誌輸出格式，下面一行是指定具體的格式
log4j.appender.Console.layout = org.apache.log4j.PatternLayout  
log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n  

#文件大小到達指定尺寸的時候產生一個新的文件
log4j.appender.File = org.apache.log4j.RollingFileAppender  
#指定輸出目錄
log4j.appender.File.File = logs/ssm.log  
#定義文件最大大小
log4j.appender.File.MaxFileSize = 10MB  
# 輸出因此日誌，若是換成DEBUG表示輸出DEBUG以上級別日誌
log4j.appender.File.Threshold = ALL  
log4j.appender.File.layout = org.apache.log4j.PatternLayout  
log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n

測試方法自行填寫；git
