这是我的MyTest.java

package com.student.spring.test;import java.util.PropertIEs;import org.springframework.beans.factory.beanfactory;import org.springframework.beans.factory.xml.Xmlbeanfactory;import org.springframework.core.io.ClassPathResource;import org.springframework.core.io.Resource;import com.student.spring.impl.CollectionsWithProps;@SuppressWarnings("deprecation")public class MyTest {    public static voID main(String[] args) {        Resource resource = new ClassPathResource("beans.xml");        beanfactory beanfactory = new Xmlbeanfactory(resource);        CollectionsWithProps cwp = (CollectionsWithProps) beanfactory                .getBean("collectionsWithProps");        System.out.println(cwp);    }}

这是CollectionsWithProps.java

package com.student.spring.impl;import java.util.PropertIEs;public class CollectionsWithProps {    private PropertIEs emails=null;    public PropertIEs getEmails() {        return emails;    }    public voID setEmails(PropertIEs emails) {        this.emails = emails;    }    public String toString(){        return "College [Props=" + emails + "]";    }}

这是我的beans.xml

最佳答案在beans.xml中,您尝试设置CollectionsWithProps的字段adminEmails.
但是该类没有该字段,它具有电子邮件字段.

修复beans.xml以使用电子邮件而不是adminEmails,或修复CollectionsWithProps的源代码将电子邮件重命名为adminEmails(以及getter和setter)
