更新時(shí)間：2020年06月20日 13:45:23 作者：Dam_e_
這篇文章主要介紹了IDEA實(shí)現(xiàn) springmvc的簡(jiǎn)單注冊(cè)登錄功能,本文通過(guò)實(shí)例代碼給大家介紹的非常詳細(xì)，對(duì)大家的學(xué)習(xí)或工作具有一定的參考借鑒價(jià)值，需要的朋友可以參考下
1.基本環(huán)境搭建
spring簡(jiǎn)介
SpringMVC框架是以請(qǐng)求為驅(qū)動(dòng)，圍繞Servlet設(shè)計(jì)，將請(qǐng)求發(fā)給控制器，然后通過(guò)模型對(duì)象，分派器來(lái)展示請(qǐng)求結(jié)果視圖。其中核心類(lèi)是DispatcherServlet，它是一個(gè)Servlet，頂層是實(shí)現(xiàn)的Servlet接口。
project創(chuàng)建
在圖中填上項(xiàng)目名稱(chēng)即可，其他直接next
如上圖所示，創(chuàng)建兩個(gè)包，并且指定包的類(lèi)型，如下圖，java包指定為Sources Root,resouces包指定為Resources root
整個(gè)目錄結(jié)構(gòu)：
pom依賴(lài)

2.
1.domain 實(shí)體類(lèi)
package domain;
public class User {
private String username;
private String password;
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;
}
}
2.dao層（實(shí)現(xiàn)了查詢(xún)和插入）
package dao;
import domain.User;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.stereotype.Repository;
@Repository
public class UserDao{
private JdbcTemplate jdbcTemplate;
private final static String sql=" Select count(*) from user_name where username=? and password=? ";
private final static String sqlInsert="insert into user_name(username,password) values (?,?)";
@Autowired
public void setJdbcTemplate(JdbcTemplate jdbcTemplate) {
this.jdbcTemplate = jdbcTemplate;
}
public int FindUser(String username,String password)
{
return jdbcTemplate.queryForObject(sql,new Object[]{username,password},Integer.class);
}
//
public void InsertUser(String username,String password){
jdbcTemplate.update(sqlInsert, username,password);
}
}
3.service層
package service;
import dao.UserDao;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
@Service
public class UserService {
private UserDao userdao;
@Autowired
public void setUserDao(UserDao userdao) {
this.userdao = userdao;
}
public boolean Match(String username,String password)
{
int count=userdao.FindUser(username,password);
return count>0;
}
public void InsertUser(String username,String password){
userdao.InsertUser(username,password);
}
}
4.controller層（這里用的包名為web）
package web;
import domain.User;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import service.UserService;
import javax.servlet.http.HttpServletRequest;
@Controller
public class UserController {
private UserService userService;
@Autowired
public void setUserService(UserService userService)
this.userService = userService;
}
@RequestMapping(value = "/index.html")
public String tologin()
{
return "login";
}
@RequestMapping(value = "/login")
public ModelAndView login(HttpServletRequest request, User user){
boolean isValidUser=userService.Match(user.getUsername(),user.getPassword());
if (isValidUser){
request.getSession().setAttribute("User",user.getUsername()+":登錄成功");
return new ModelAndView("success");
}else{
return new ModelAndView("login");
}
}
@RequestMapping("/insert")
public String InsertUser(User user, Model model){
userService.InsertUser(user.getUsername(),user.getPassword());
model.addAttribute("Insert","注冊(cè)成功");
return "success1";
}
@RequestMapping("/insertPage")
public String InsertPage()
{
return "register";
}
}
3.xml配置
1.web.xml
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd" > <web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0"> <display-name>Archetype Created Web Application</display-name> <display-name>Archetype Created Web Application</display-name> <!--配置Spring的監(jiān)聽(tīng)器，默認(rèn)只加載WEB-INF目錄下的applicationContext.xml配置文件--> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!--設(shè)置配置文件的路徑--> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <servlet> <servlet-name>dispatcherServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:dispatcher-servlet.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>dispatcherServlet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> </web-app>
resource里面新建兩個(gè)spring xml文件
2.applicationContext.xml
spring的配置文件applicationContext.xml中的一些配置的作用。
