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

spring-beans-3.0.xsd">

    minemails">
            

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)
