java用户管理系统用的什么技术

什么是SSM框架

SSM（Spring+SpringMVC+MyBatis）框架集由Spring、MyBatis两个开源框架整合而成（SpringMVC是Spring中的部分内容）。常作为数据源较简单的web项目的框架。

Spring

Spring就像是整个项目中装配bean的大工厂，在配置文件中可以指定使用特定的参数去调用实体类的构造方法来实例化对象。也可以称之为项目中的粘合剂。
　　Spring的核心思想是IoC（控制反转），即不再需要程序员去显式地new一个对象，而是让Spring框架帮你来完成这一切。

SpringMVC

SpringMVC在项目中拦截用户请求，它的核心Servlet即DispatcherServlet承担中介或是前台这样的职责，将用户请求通过HandlerMapping去匹配Controller，Controller就是具体对应请求所执行的操作。SpringMVC相当于SSH框架中struts。

mybatis

mybatis是对jdbc的封装，它让数据库底层操作变的透明。mybatis的操作都是围绕一个sqlSessionFactory实例展开的。mybatis通过配置文件关联到各实体类的Mapper文件，Mapper文件中配置了每个类对数据库所需进行的sql语句映射。在每次与数据库交互时，通过sqlSessionFactory拿到一个sqlSession，再执行sql命令。

建设项目

本项目使用的是maven模型

1、首先创建Maven项目选择

在这里插入图片描述

2、点击next

3、但是由于国外的数据仓下载jar包速度会偏慢，可以使用阿里云镜像进行下载，可以在.m2文件夹下的setting.xml中加入以下代码

<mirror>
	<id>alimaven</id>
	<mirrorOf>central</mirrorOf>
	<name>aliyun maven</name>
	<url>http://maven.aliyun.com/nexus/content/repositories/central/</url>
</mirror>

4、在user setting files选择setting.xml

5、在properties中添加属性

archeTypeCatlog、internal可以加快Maven骨架生成速度。

6、项目创建完成之后进行配置文件

可以根据下面的链接进行配置

链接: Maven配置文件与jsp.

7、创建规范文件结构

效果图

用户登录功能

需要实现的功能是判断用户登录的账号与密码，成功进入页面，错误则登录失败。调用login请求实现

完成对用户增删改查功能的实现

删除用户

通过id删除用户信息，调用delete方法，返回findAll.do，显示删除后的信息
在这里插入图片描述

新增用户

向数据库里新增用户信息，调用add方法，返回findAll.do，显示新增用户后的信息
关键代码实现
在这里插入图片描述

修改用户信息

首先调用selectbyid查询出当前用户信息，再使用update方法改写用户信息，修改完成返回findAll.do方法，显示修改完成的用户信息

实现分页

一次性将所有的数据查询出来会增加服务器的负荷，所以需要用分页有选择性地将数据读取。
一每页五条记录为例
需要定义list、size （每页查询记录的数量）、totalcount （查询所有记录的数量）、totalpage（查询所有记录所需要的页数）、currentPage（显示当前页数）。
benn.PageInfo类

bean.User

package com.zhongruan.bean;

public class User {
    public User(){

    }

    public User(int id, String username, String password) {
        this.id = id;
        this.username = username;
        this.password = password;
    }

    public User(String username, String password) {
        this.username = username;
        this.password = password;
    }

    private int id;
    private String username;
    private String password;

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    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;
    }

    @Override
    public String toString() {
        return "User{" +
                "id=" + id +
                ", username='" + username + '\'' +
                ", password='" + password + '\'' +
                '}';
    }
}

过滤器

其功能主要是在filter里面判断session里是否有user，如果没有user并且当前的请求不是login.do 跳转到登入页面否则继续执行。
新建filter文件夹和LoginFilter
在这里插入图片描述

package com.zhongruan.filter;

import com.zhongruan.bean.User;

import javax.servlet.*;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
import java.io.IOException;

public class LoginFilter implements Filter {
    @Override
    public void init(FilterConfig filterConfig) throws ServletException {

    }

    @Override
    public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
        HttpServletRequest request = (HttpServletRequest) servletRequest;
        HttpServletResponse response = (HttpServletResponse) servletResponse;
        HttpSession session = request.getSession();
        User user = (User) session.getAttribute("user");
        String uri = request.getRequestURI();
        if (user==null && uri.indexOf("login.do")==-1){
            response.sendRedirect(request.getContextPath()+"login.jsp");
        }else {
            filterChain.doFilter(request,response);
        }
    }

    @Override
    public void destroy() {

    }
}

这样可以拦截所有.do请求，当session中没有user或不是login返回登录页面。
