项目视频演示

domain（pojo层）的两个实体类

Account

package com.domain;
 
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import lombok.ToString;
 
@ToString//tosting方法
@Data//除了有参构造都有了
@AllArgsConstructor//有参
@NoArgsConstructor//无参
public class Account {
 
    private Integer id;
    private String name;
    private Double money;
    private String detail;
 
}

user下

@Data
@AllArgsConstructor
@NoArgsConstructor
@ToString
public class User {
    private Integer id;
    private String username;
    private String password;
    private Integer isAdmin;
}

mapper（dao层）下

AccountMapper

//只显示出了部分，其余可以在我的资源中查看

package com.mapper;
 
import com.domain.Account;
import com.domain.User;
import org.apache.ibatis.annotations.*;
import org.apache.ibatis.annotations.Param;
import java.util.List;
 
public interface AccountMapper {
   @Insert(" insert into account values(#{id},#{name},#{money},#{detail})")
    public void save(Account account);
 
    @Select(" select * from account")
    public List findAll();
 
    @Select("select *from account where id=#{id}")
    public Account findById(int id);
 
//只显示出了部分，其余可以在我的资源中下载
 
 
}

service和serviceImpl

AccountServie下

只显示出了部分，其余可以在我的资源中查看

package com.service;
 
import com.domain.Account;
import com.domain.User;
import org.apache.ibatis.annotations.Param;
 
import java.util.List;
 
public interface AccountService {
 
    public void save(Account account);
 
    public List findAll();
    public Account findById(int id);
    public List findByIds(String name);
 
 
 
}

impl下

 
 
@Service("accountService")
public class AccountServiceImpl implements AccountService {
 
    @Autowired
    private AccountMapper accountMapper;
 
 
    @Override
    public List checkUser(String username, String password) {
        return accountMapper.checkUser(username, password);
    }
 
    //查询所有用户
    @Override
    public List findUsers() {
        return accountMapper.findUsers();
    }
 
 
}

Controller层

AccountController

只显示出了部分，其余可以在我的资源中查看

 
 
@Controller
@RequestMapping("/account")
public class AccountController {
    //用来存当前用户名
 
String [] userString= new String[1];
 
 
    //注册界面
    @RequestMapping("/signUp")
    public String signUp(String username,String password,Model model){
        accountService.signUp(username, password);
        model.addAttribute("mess", "注册成功");
//        使用了forward错误信息才会正常显示，使用了redirect会跑到地址栏去
        return "forward:/index.jsp";
    }
 
 
 
 
 
}

配置文件

applicationContext.xml下

 
    
    <context:component-scan base-package="com">

    context:component-scan>
 
    
    <context:property-placeholder location="classpath:jdbc.properties"/>
 
    
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="${jdbc.driver}">property>
        <property name="jdbcUrl" value="${jdbc.url}">property>
        <property name="user" value="${jdbc.username}">property>
        <property name="password" value="${jdbc.password}">property>
    bean>
 
 
 
 

spring-mvc下

 
 
    
    <context:component-scan base-package="com.controller"/>
    
    <mvc:annotation-driven/>
