集合类型的依赖注入问题例子，例如：list,array,set,map,properties

CollectionBean类

package com.xqw.pojo;

import java.util.*;

public class CollectionBean {
    private List<String> lists;
    private Integer[] arrs;
    private Set<String> sets;
    private Map<String, String> maps;
    private Properties properties;

    public List<String> getLists() {
        return lists;
    }

    public void setLists(List<String> lists) {
        this.lists = lists;
    }

    public Integer[] getArrs() {
        return arrs;
    }

    public void setArrs(Integer[] arrs) {
        this.arrs = arrs;
    }

    public Set<String> getSets() {
        return sets;
    }

    public void setSets(Set<String> sets) {
        this.sets = sets;
    }

    public Map<String, String> getMaps() {
        return maps;
    }

    public void setMaps(Map<String, String> maps) {
        this.maps = maps;
    }

    public Properties getProperties() {
        return properties;
    }

    public void setProperties(Properties properties) {
        this.properties = properties;
    }

    @Override
    public String toString() {
        return "CollectionBean{" +
                "lists=" + lists +
                ", arrs=" + Arrays.toString(arrs) +
                ", sets=" + sets +
                ", maps=" + maps +
                ", properties=" + properties +
                '}';
    }
}

测试类

import com.xqw.pojo.CollectionBean;
import org.springframework.beans.factory.BeanFactory;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class CollectionBeanTest {
    public static void main(String[] args) {
        BeanFactory beanFactory=new ClassPathXmlApplicationContext("bean2.xml");
        CollectionBean collectionBean= (CollectionBean) beanFactory.getBean("collectionBean");
        System.out.println(collectionBean );
