SqlMapConfig.xml配置模板

<?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>    <environments default="environment">        <environment id="environment">            <transactionManager type="JDBC" />            <dataSource type="POOLED">                <property name="driver"                          value="oracle.jdbc.OracleDriver" />                <property name="url"                          value="jdbc:oracle:thin:@192.168.0.23:1521:tarena10g"/>                <property name="username" value="demo" />                <property name="password" value="demo" />            </dataSource>        </environment>    </environments>    <mappers>        <mapper resource="org/tarena/entity/Emp.xml" />    </mappers></configuration>

注意：配置标签需严格按照
(properties, settings, typeAliases, typeHandlers, objectFactory, objectWrapperFactory, reflectorFactory, plugins, environments, databaseIdProvider, mappers)
顺序，否则会报错
