Java SpringBean构造函数arg拒绝我要传入的对象（实现myInterface），构造函数param的类型为myInterface

我正在尝试生成AuthenticationController类型的bean。身份验证控制器的构造函数有一个类型为DataSource的参数，称为securityDataSource。在我的安全上下文xml中，我使用以下代码声明bean

摘录自webSecurityConfig.xml：

<bean id="authoritiesConroller" 
       class="honors.uh.edu.security.AuthoritiesController">
        <constructor-arg ref="securityDataSource"/>
</bean>

我得到的返回错误是由以下原因引起的：

：java.lang.IllegalArgumentException:'dataSource'或'jdbcTemplate'是必需的

。为什么现在允许这样做？DriverManager数据源是数据源的一个实现，所以不应该允许我将其作为参数传递吗

编辑：这里是完整的错误-

问题解决了！

位从来都不是问题。问题是，因为我的类AuthenticationController扩展了类JdbcDaoSupport，所以它希望我声明一个名为“dataSource”的属性。这从来不是一个类型冲突的问题

现在的功能性bean声明如下所示：

<bean id="authoritiesConroller" class="honors.uh.edu.security.AuthoritiesController">
        <property name="dataSource" ref="securityDataSource"/>
        <constructor-arg ref="securityDataSource"/>
</bean>

我相信有一种更好的方法可以避免两次传入数据源，但这至少解决了问题。谢谢你的帮助

您能否再次验证完全限定名，以及哪个版本的Spring？我不确定您所说的完全限定名是什么意思。我正在使用4.0.3.0版本
