由于一些奇怪的原因,这个dataSource bean可以在我的三个dao-beans中找到,但在其他的dao-bean中找不到(例如Spring-name1)。差异是什么?
引用bean' dataSource'找不到
这是代码:
不工作bean(Spring-name1):
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<bean id="cheopsDAO" class="se.kth.domain.dao.impl.JdbcCheopsDAO">
<property name="dataSource" ref="dataSource" />
</bean>
</beans>
工作bean(Spring-name2):

<property value="root" name="username" />
<property value="test" name="password" />
</bean>
</beans>
我在相应的包中有所需的DAO文件,为什么第二个工作但不是第一个?没有区别......
正手感谢!

我通过为我的项目添加配置集(Bean支持)来修复此问题。不知道这是否是正确的解决方案,但它至少删除了错误:
右键单击project-&gt; properties-&gt; Spring-&gt; Bean Support-&gt;配置集 (在上一页之前进行扫描),然后我将它们全部添加 一起在随机配置集中。 =)
