1 看看数据源的配置是否有问题。
<bean name="dataSource" class="com.alibaba.druid.pool.DruidDataSource" destroy-method="close">
<property name="url" value="${url}" />
<property name="username" value="${user}" />
<property name="password" value="${password}" />
<property name="initialSize" value="2" />
<property name="maxActive" value="20" />
<property name="minIdle" value="2" />
<property name="maxWait" value="60000" />
</bean>
2 导包是否有问题。
3 但是在我的这个代码中,在数据源配的url,他最后取得的值是 我在pom.xml里配置的url <url>http://maven.apache.org</url>,主要我不知道他是怎么去得到这个值的!
两种修改方面:
1 修改数据源配置文件
<property name="url" value="${jdbc_url}" />
<property name="username" value="${jdbc_user}" />
<property name="password" value="${jdbc_password}" />
2 去掉pom.xml配置里的<url>
4 之前代码没该过,也是可以运行的~~~(就突然出现这个问题了)
