必须为元素类型"bean"声明依赖关系检查"

Question

<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN"
        "http://www.springframework.org/dtd/spring-beans-2.0.dtd">
<beans>
<bean id="engine" class="beans.Engine" dependency-check="none" >
</bean>
<bean id="car" class="beans.Car">
    <property name="carname" value="Audi" />
    <property name="engine" ref="engine"/>
</bean>

**我的引擎课程看起来像**

在这里我避免通过属性

package beans;
public class Engine {
public Engine()
{
    System.out.println("Engine");
}
private String modelyear;
public void setModelyear(String modelyear) {
    this.modelyear = modelyear;
}
public String getModelyear() {
    return modelyear;
}

}

我尝试设置依赖项检查

时得到了此例外

dependency-check已弃用(源(。

Quote：

当前的春豆3.0 XSD更有利于更明确的配置，而较少依赖容器来提供一些配置"魔术"。

删除了以下属性：

• "默认依赖性 - 检查"根元素的属性
• "依赖关系检查"元素的属性
