我出现这个错误的原因是：我的applicationContext.xml中的配置出现了问题，
如下：
<?xml version="1.0" encoding="UTF-8"?>

创建一个jdbcTemplate bean 将dataSources 注入
com.alibaba.druid.pool.DruidDataSource ；连接池

<!--
DataSOurce 接口，为了从数据库中得到数据，需要获取一个数据库的连接，Spring通过DataSources对象来完成这个链接，
DataSource 是JDBC规范的一部分
他被视为一个通用的数据库连接工厂
通过DataSource ，Container,Framework,可以将连接池及事务管理的细节从应用代码中分理出来

</bean>
<bean id="bankDaoImpl" class="com.zzxt.java.servlet.BankDaoImpl">
<property name="namedParameterJdbcTemplate" ref="namedParameterJdbcTemplate"></property>
</bean>
</beans>由于xml文件中我配置的是这个NameParameterJdbcTemplate,而我的工程中却使用了没有配置完全的JdbcTemlpate,所以引发了
DataSource not set 的错误。
<bean id="namedParameterJdbcTemplate" class="org.springframework.jdbc.core.namedparam.NamedParameterJdbcTemplate">
<constructor-arg name="dataSource" ref="dataSource"></constructor-arg>
</bean>
<bean id="bankDaoImpl" class="com.zzxt.java.servlet.BankDaoImpl">
<property name="namedParameterJdbcTemplate" ref="namedParameterJdbcTemplate"></property>
</bean>这个问题对我的工程来说具有特殊性， 但是也具有一般性，出现这个问题的原因肯定在xml文件配置中。
