如何在spring框架中修复我的异常？

Question

 import java.awt.List;
   import java.util.Properties;

   public class CollectionExample {

    private List examplelist;

    private Properties exampleprop;

    public List getExamplelist() {
        System.out.println("List Element : " + examplelist);
        return examplelist;
    }

    public void setExamplelist(List examplelist) {
        examplelist = examplelist;
    }

    public Properties getExampleprop() {
        System.out.println("List Element : " + exampleprop);
        return exampleprop;
    }

    public void setExampleprop(Properties exampleprop) {
        this.exampleprop = exampleprop;
    }

}

    public class CollectionExample {

    private List examplelist;

    private Properties exampleprop;

    public List getExamplelist() {
        System.out.println("List Element : " + examplelist);
        return examplelist;
    }

    public void setExamplelist(List examplelist) {
        examplelist = examplelist;
    }

    public Properties getExampleprop() {
        System.out.println("List Element : " + exampleprop);
        return exampleprop;
    }

    public void setExampleprop(Properties exampleprop) {
        this.exampleprop = exampleprop;
}

}



My .xml file is :
<bean id = "collectionExample"  class = "com.demo.spring.beans.CollectionExample" >
  <property name="examplelist">
    <list>
           <value>Credit Card</value>
           <value>COD</value>
           <value>Check</value>
           <value>Cash</value>
    </list>
  </property>
  <property name="exampleprop">
    <props>
        <prop key="one">Server Name</prop>
         <prop key="one">User Name</prop>
          <prop key="one">Password</prop>
           <prop key="one">Secure Token</prop>
    </props>
  </property>

</bean>

仔细看这部分错误消息：

无法将类型[java.util.ArrayList]的值转换为属性“exampleList”所需的类型[java.awt.List]

您在代码中导入了错误的列表。更改此：

import java.awt.List;

import java.util.List;
