Spring属性注入set方式注入集合

这个是被注入的类
package Collection;

import java.util.ArrayList;
import java.util.Map;
import java.util.Properties;
import java.util.Set;

public class collections {

    private ArrayList<String> ayyay;

    public void setAyyay(ArrayList<String> ayyay) {
        this.ayyay = ayyay;
    }
    private Set<String> sets;
    private Map<Integer,String> maps;
    private Properties  pre;

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

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

    public ArrayList<String> getAyyay() {
        return ayyay;
    }

    public Properties getPre() {
        return pre;
    }

    public void setPre(Properties pre) {
        this.pre = pre;
    }

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

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

xml文件为
