3，构建基本目录

页面
调用service层的函数做事务处理，代码逻辑的实现就写在service层
sql
数据库数据时，会调用dao层的sql接口
函数的类。封装dao层取出来的数据为一个对象

　　　　后台页面目录

页面文件
文件是安全的
登录后才可以访问的后台管理页面）

文件

　　　　首页

　　　　　　文件

4，文件配置

　　数据库

　　　　数据库连接配置文件 db.properties(new一个file)

　　　　内容

MysqL、sql server，3者的写法均不同变量名可以随意取，但是要注意，不能和系统内置的变量名起冲突等号右边的内容，不要加双引号或单引号

　　　　MysqL的配置　　

MysqL.jdbc.Driver;//数据库驱动

MysqL://localhost:3306/blog?characterEncoding=utf-8 //数据库地址（一般写ip地址）

数据库用户名

数据库密码

Highlighter">

MysqL.jdbc.Driver
jdbc.url =jdbc:MysqL://localhost:3306/blog?characterEncoding=utf-8
jdbc.username = root
jdbc.password =root

配置文件 spring-mybatis.xml

分页的配置文件（pageHelper）

pageHelper.PageInterceptor">

数据库数据

数据库里面user是关键字）

　　　　　　

public class User {
private int user_id;
private String user_name;
private String user_password;
public int getUser_id() {
return user_id;
}
public void setUser_id(int user_id) {
this.user_id = user_id;
}
public String getUser_name() {
return user_name;
}
public void setUser_name(String user_name) {
this.user_name = user_name;
}
public String getUser_password() {
return user_password;
}
public void setUser_password(String user_password) {
this.user_password = user_password;
}

}

登录的方法

import org.apache.ibatis.annotations.Param;

import com.ssm.view.User;

public interface UserDao {
/**

登录操作

@param user_name 用户名

@param user_password 密码

@return
*/
public User login(@Param("user_name")String user_name,@Param("user_password")String user_password);
}

　　　　文件夹用来放mybatis dao的配置文件

文件名称为UserDaomapper.xml

<mapper namespace="com.ssm.dao.UserDao">

<resultMap id="UserMap" type="com.ssm.view.User"> <result column="user_id" property="user_id" /> <result column="user_name" property="user_name" /> <result column="user_password" property="user_password" /> </resultMap> <select id="login" resultMap="UserMap"> SELECT * FROM user WHERE user_name=#{user_name} and user_password=#{user_password} </select>

登录的方法
