环境搭建

导入基础项目

基础项目中已经包含了静态页面，以及js、css等等；

 导包

l  struts2

l  c3p0

l  mysql

l  dbutils

l  beanutils

 

 建包

l  cn.itcast.user.domain

l  cn.itcast.user.dao

l  cn.itcast.user.service

l  cn.itcast.user.web.action

 主页

让主页转发到/login/login.jsp

1、创建数据库

CREATE DATABASE empmng;

#创建用户，指定为只能本地访问，不能远程访问
create user empmng@localhost identified by '123';
#授权
grant all on empmng.* to empmng@localhost;

CREATE TABLE S_User(
	uid CHAR(32) PRIMARY KEY, 
	username VARCHAR(50),
	loginname VARCHAR(50),
	loginpass VARCHAR(50),
	gender VARCHAR(10),
	birthday VARCHAR(50),
	education VARCHAR(20),
	cellphone VARCHAR(50),
	hobby VARCHAR(20),
	filepath VARCHAR(500),
	filename VARCHAR(100),
	remark VARCHAR(500)
);

c3p0-config.xml:

  
    com.mysql.jdbc.Driver
    jdbc:mysql:///struts2-javaee16
    root
    1234
    3
    30
    5
    3
  

2、创建User类

对应t_user表来创建User类。

3、创建javabean

User：

package cn.itcast.user.domain;

import java.io.File;

public class User {
	private String uid;
	private String username;
	private String loginname;
	private String loginpass;
	private String gender;
	private String birthday;
	private String education;
	private String cellphone;
	private String hobby;
	private String filepath;
	private String filename;
	private String remark;
//upload 字段在数据库中并没有列与之对应
// 接受表单提交的是否有简历的参数
	private String upload;
	
	
	


	public String getUpload() {
		return upload;
	}

	public void setUpload(String upload) {
		this.upload = upload;
	}

	public String getUid() {
		return uid;
	}

	public void setUid(String uid) {
		this.uid = uid;
	}

	public String getUsername() {
		return username;
	}

	public void setUsername(String username) {
		this.username = username;
	}

	public String getLoginname() {
		return loginname;
	}

	public void setLoginname(String loginname) {
		this.loginname = loginname;
	}

	public String getLoginpass() {
		return loginpass;
	}

	public void setLoginpass(String loginpass) {
		this.loginpass = loginpass;
	}

	public String getGender() {
		return gender;
	}

	public void setGender(String gender) {
		this.gender = gender;
	}

	public String getBirthday() {
		return birthday;
	}

	public void setBirthday(String birthday) {
		this.birthday = birthday;
	}

	public String getEducation() {
		return education;
	}

	public void setEducation(String education) {
		this.education = education;
	}

	public String getCellphone() {
		return cellphone;
	}

	public void setCellphone(String cellphone) {
		this.cellphone = cellphone;
	}

	public String getHobby() {
		return hobby;
	}

	public void setHobby(String hobby) {
		this.hobby = hobby;
	}

	public String getFilepath() {
		return filepath;
	}

	public void setFilepath(String filepath) {
		this.filepath = filepath;
	}

	public String getFilename() {
		return filename;
	}

	public void setFilename(String filename) {
		this.filename = filename;
	}

	public String getRemark() {
		return remark;
	}

	public void setRemark(String remark) {
		this.remark = remark;
	}

	@Override
	public String toString() {
		return "User [uid=" + uid + ", username=" + username + ", loginname="
				+ loginname + ", loginpass=" + loginpass + ", gender=" + gender
				+ ", birthday=" + birthday + ", education=" + education
				+ ", cellphone=" + cellphone + ", hobby=" + hobby
				+ ", filepath=" + filepath + ", filename=" + filename
				+ ", remark=" + remark + "]";
	}

}

用户登录：

用户列表：

查看用户：

保存用户：

dao：

UserDao:

package cn.itcast.user.dao;

import java.util.List;

import cn.itcast.user.domain.User;

public interface UserDao {
	//根据登录名称获得用户对象
	User  getUserByLoginName(String loginName);
	// 根据查询条件获得用户列表
	List getUserByCondition(User u);
	//保存用户对象
	void  saveUser(User u);
	//根据userid 获得user对象
	User getUserByUid(String id);
}

UserDaoImpl:

package cn.itcast.user.dao;

import java.sql.SQLException;
import java.util.ArrayList;
import java.util.List;

import org.apache.commons.dbutils.QueryRunner;
import org.apache.commons.dbutils.handlers.BeanHandler;
import org.apache.commons.dbutils.handlers.BeanListHandler;

import com.mchange.v2.c3p0.ComboPooledDataSource;

import cn.itcast.user.domain.User;

public class UserDaoImpl implements UserDao {
	private static QueryRunner qr = new QueryRunner(new ComboPooledDataSource());
	
	public User getUserByLoginName(String loginName) {
		//1 书写sql语句
		String sql = " select * from tab_user where loginname = ? ";
		//2 调用runner的 query方法
		try {
			User u  = qr.query(sql, new  BeanHandler(User.class), loginName);
			//3 返回
			return u;
		} catch (SQLException e) {
			e.printStackTrace();
			throw new RuntimeException("查询用户失败!");
		}
	}

	public List getUserByCondition(User u) {
		String sql = " select * from tab_user  where 1=1";
		//准备放置参数的集合
		List
