解决思路:

mybaits配置文件指定的mapper.xml方式不对或者路径不对

解决:

mybaits-config.xml

<?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>

	<!-- <properties resource="db.properties"></properties> -->

	<!-- <environments default="development"> <environment id="development">

		<transactionManager type="JDBC" /> <dataSource type="POOLED"> <property name="driver"

		value="${driver}" /> <property name="url" value="${url}" /> <property name="username"

		value="${username}" /> <property name="password" value="${password}" /> </dataSource>

		</environment> </environments> -->

	<!-- 开启延迟加载 -->

	<settings>

		<setting name="lazyLoadingEnabled" value="true" />

		<setting name="aggressiveLazyLoading" value="false" />

		<setting name="logImpl" value="STDOUT_LOGGING" />

	</settings>

	<mappers>

		<!-- 原先写成了这个鬼样(注释那句), 它无法找到这个路径 -->

		<!-- <mapper resource="com.blog.cheng.network.www.mapper.UserPojoMapper.xml" /> -->

		<mapper resource="com/blog/cheng/network/www/mapper/UserPojoMapper.xml" />

	</mappers>

</configuration>

再贴上applicationContext.xml
