Spring支持dao模式的小实例

用Spring框架往数据库插入一条语句。

机构图：

package henu.bean;

import java.io.Serializable;
import java.util.Set;

public class User implements Serializable{
	private String username;
	private String password;
	private String gender;
	private String email;
	private String hobby;
	private String introduction;
	private String birthdate;
	private String usertype;
	
	public String getUsername() {
		return username;
	}
	public void setUsername(String username) {
		this.username = username;
	}
	public String getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;
	}
	public String getGender() {

	}
	public void setGender(String gender) {

	}
	public String getEmail() {

	}
	public void setEmail(String email) {
