spring注入Set，List，Properties和Map

 

 

好久没有写代码了 连spring注入都忘记了，真是老了不行了，记录下吧

 

java代码

 

package hua;

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

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

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

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

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

	public Properties getProperties() {
		return properties;
	}

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

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

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

	@Override
	public String toString() {
		StringBuffer sb = new StringBuffer();
		sb.append("\nSets:\n");
		for (Iterator<String> iterator = getSets().iterator(); iterator
				.hasNext();) {
			sb.append(iterator.next() + "  ");
		}
		sb.append("\nLists:\n");
		for (Iterator<String> iterator = getLists().iterator(); iterator
				.hasNext();) {
			sb.append(iterator.next() + "  ");
		}
		sb.append("\nProperties:\n");
		for (Enumeration<String> e = (Enumeration<String>) getProperties()
				.propertyNames(); e
				.hasMoreElements();) {
			String key = (String) e.nextElement();
			sb.append(key + " : " + getProperties().getProperty(key) + "  ");
		}
		sb.append("\nMaps:\n");
		for (Object o : getMaps().keySet()) {
			sb.append(o + " : " + getMaps().get(o) + "  ");
		}

		return sb.toString();
	}

}

测试

 

public static void main(String[] args) {  
        ApplicationContext context = new ClassPathXmlApplicationContext(  
                "appcontext.xml");  
        DomainTest psb = (DomainTest) context.getBean("domainTest");  
        System.out.println(psb);  
    }
