本文详细介绍了如何在Java Spring框架中配置并使用PersonServiceBean类，包括其内部属性如集合、映射和属性集的注入与获取方法。通过XML配置文件实例演示了如何初始化和调用该类的方法。

package com.dao.bean.www;

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

public interface PersonServiceDao {

	public Map<String, String> getMaps();
	
	public Properties getProperties();

	public List<String> getLists();

	public Set<String> getSets();

	public abstract void save();

}

package com.bean.www;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.HashSet;
import java.util.List;
import java.util.Map;
import java.util.Properties;
import java.util.Set;

import com.PersonDaoBean.test.PersonDao;
import com.dao.bean.www.PersonServiceDao;

public class PersonServiceBean implements PersonServiceDao {

	private Set<String> sets = new HashSet<String>();
	private List<String> lists = new ArrayList<String>();
	private Properties properties = new Properties();
	private Map<String, String> maps = new HashMap<String, String>();

	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;
	}

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

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

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

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

	public void save() {

	}

}
