员工管理系统——基于springboot
1.首页定制
所有页面的静态资源需要thymeleaf
静态资源下载地址
2.国际化
改完后的index.html
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
<meta name="description" content="">
<meta name="author" content="">
<title>Signin Template for Bootstrap</title>
<!-- Bootstrap core CSS -->
<link th:href="@{/css/bootstrap.min.css}" rel="stylesheet">
<!-- Custom styles for this template -->
<link th:href="@{/css/signin.css}" rel="stylesheet">
</head>
<body class="text-center">
<form class="form-signin" action="dashboard.html">
<img class="mb-4" th:src="@{/img/bootstrap-solid.svg}" alt="" width="72" height="72">
<h1 class="h3 mb-3 font-weight-normal" th:text="#{login.btn}">Please sign in</h1>
<label class="sr-only" th:text="#{login.username}">Username</label>
<input type="text" class="form-control" th:placeholder="#{login.username}" required="" autofocus="">
<label class="sr-only" th:text="#{login.password}">Password</label>
<input type="password" class="form-control" th:placeholder="#{login.password}" required="">
<div class="checkbox mb-3">
<label>
<input type="checkbox" value="remember-me" > [[#{login.remember}]]
</label>
</div>
<button class="btn btn-lg btn-primary btn-block" type="submit" >[[#{login.btn}]]</button>
<p class="mt-5 mb-3 text-muted">© 2017-2018</p>
<a class="btn btn-sm">中文</a>
<a class="btn btn-sm">English</a>
</form>
</body>
</html>
接下来改进这里
MyLocalResovler.java
package com.shao.config;
import org.springframework.web.servlet.LocaleResolver;
import org.thymeleaf.util.StringUtils;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.util.Locale;
public class MyLocalResolver implements LocaleResolver {
//解析请求
@Override
public Locale resolveLocale(HttpServletRequest request) {
//获取请求中的参数连接
String language = request.getParameter("l");
//如果没有就使用默认的
Locale locale = Locale.getDefault();
//如果请求的连接携带了国际化参数
if(!StringUtils.isEmpty(language)){
//国家 地区
String[] split = language.split("_");
locale = new Locale(split[0], split[1]);
}
return locale;
}
@Override
public void setLocale(HttpServletRequest request, HttpServletResponse response, Locale locale) {
}
}
WebMvcConfig.java
package com.shao.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.LocaleResolver;
import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
@Configuration
public class WebMvcConfig implements WebMvcConfigurer {
@Override
public void addViewControllers(ViewControllerRegistry registry) {
registry.addViewController("/").setViewName("index");
registry.addViewController("/index.html").setViewName("index");
}
//自定义的国际化组件生效了
@Bean
public LocaleResolver localeResolver(){
return new MyLocalResolver();
}
}
3.登录功能实现
LoginController.java
package com.shao.controller;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import org.thymeleaf.util.StringUtils;
@Controller
public class LoginController {
@RequestMapping("/user/login")
public String login(@RequestParam("username") String username,
@RequestParam("password") String password,
Model model){
//具体的业务，判断是否登录成功
if(!StringUtils.isEmpty(username) && "123".equals(password)){
return "redirect:/main.html";
}else{
//告诉用户登陆失败
model.addAttribute("msg", "用户名或密码错误!");
return "index";
}
//return "ok";
}
}
4.登录拦截器
LoginHandlerInterceptor.java
package com.shao.config;
import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.ModelAndView;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class LoginHandlerInterceptor implements HandlerInterceptor {
@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
//登录成功之后，应该有用户的session
Object loginUser = request.getSession().getAttribute("loginUser");
if(loginUser == null){
request.setAttribute("msg", "没有权限，请先登录！");
request.getRequestDispatcher("/index.html").forward(request,response);
return false;
}
return true;
}
//@Override
//public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception {
//
//}
//
//@Override
//public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception {
//
//}
}
上面注册的加入代码
@Override
public void addInterceptors(InterceptorRegistry registry) {
//拦截所有请求
registry.addInterceptor(new LoginHandlerInterceptor())
.addPathPatterns("/**")
.excludePathPatterns("/index.html", "/",
"/user/login", "/css/**", "/js/**", "/img/**");
}
5.展示员工列表
先改两处位置
package com.shao.controller;
import com.shao.dao.EmployeeDao;
import com.shao.pojo.Employee;
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 java.util.Collection;
@Controller
public class EmployeeController {
@Autowired
private EmployeeDao employeeDao;
@RequestMapping("/emps")
public String list(Model model) {
Collection<Employee> employees = employeeDao.getEmployees();
model.addAttribute(employees);
return "emp/list";//返回到list页面
}
}
6.增加员工
7.修改员工
8.删除及404处理
主要是给自己看的，所以肯定会出现很多错误哈哈哈哈哈
