Spring依赖注入有两种：构造器注入与Set注入

其中以Set注入为首选。下面演示几个示例。

Bean类：User

package com.lwf.bean;

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

public class User {

	private String name;
	private int age;
	private List listValues;
	
	private Map map ;
	private Set set;
	private String [] array;
	private Date date;
	
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public int getAge() {
		return age;
	}
	public void setAge(int age) {
		this.age = age;
	}
	public List getListValues() {
		return listValues;
	}
	public void setListValues(List listValues) {
		this.listValues = listValues;
	}
	public Map getMap() {
		return map;
	}
	public void setMap(Map map) {
		this.map = map;
	}
	public Set getSet() {
		return set;
	}
	public void setSet(Set set) {
		this.set = set;
	}
	public String[] getArray() {
		return array;
	}
	public void setArray(String[] array) {
		this.array = array;
	}
	public Date getDate() {
		return date;
	}
	public void setDate(Date date) {
		this.date = date;
	}
}
