数据库如下：

User类：

package com.zh.pojo;

public class User {
	private Integer id;
	private String username;
	private String password;
	private Integer age;

	public Integer getId() {
		return id;
	}
	public void setId(Integer id) {
		this.id = id;
	}
	public String getUsername() {
		return username;
	}
	public void setUsername(String username) {

	}
	public String getPassword() {
		return password;
	}

@Service("userService")
public class UserServiceImpl implements IUserService {

	@Resource
    private IUserDao userDao;
	@Override
	public User getUserById(int id) {
		 return userDao.findUserById(id);
	}

}

IUserDao类：

package com.zh.dao;

import com.zh.pojo.User;

public interface IUserDao {
	User findUserById(Integer id);
}

UserMapper.xml：

        from user_t
        where id = #{id}

index.jsp:

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <title>test</title>
  </head>
  <body>
    ${user.username}
  </body>
</html>

这样就搭建完成了，启动tomcat，在浏览器中输入localhost:8080/ssm/user/index?id=1
