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>

**我的引擎类看起来像这样**

这里我避免传递属性

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

时出现此异常

Answer 1

dependency-check已弃用（source）。

引用：

当前的spring-beans 3.0 XSD支持更明确的配置，并且更少依靠容器来提供一些配置＆＃34; magic＆＃34;。

删除了以下属性：


＆＃34;默认依赖性检查＆＃34;根元素的属性

＆＃34;依赖性的检查＆＃34;元素的属性

依赖检查“必须为元素类型”bean“声明”
