大家好昨天我问了一些关于Spring MVC的问题，关于从jsp注入JavaScript的jsp孩子中读取变量的可能性。
现在，我不知道如何制作这样的流程，我正在开发一个网络应用程序，下一个流程。
使用安全性登录，根据白皮书重新定向到用户
protected String determineTargetUrl(Authentication authentication) {
boolean isUser = false;
boolean isAdmin = false;
boolean isSupervisor = false;
Collection<? extends GrantedAuthority> authorities
= authentication.getAuthorities();
for (GrantedAuthority grantedAuthority : authorities) {
if (grantedAuthority.getAuthority().equals("ROLE_USER")) {
isUser = true;
break;
} else if (grantedAuthority.getAuthority().equals("ROLE_ADMIN")) {
isAdmin = true;
break;
} else if (grantedAuthority.getAuthority().equals("ROLE_SUPERVISOR")) {
isSupervisor = true;
break;
}
}
if (isUser) {
return "/user";
} else if (isAdmin) {
return "/admin";
} else if (isSupervisor) {
return "/supervisor";
} else {
throw new IllegalStateException();
}
}
我会专注于我的管理员用户（主管有相同的主页，用户有一个特殊的页面）
控制器 我的控制器是我的视图，并使用ModelAndView发送一些值。
@Controller
@RequestMapping(value = "/admin")
public class AdminController {
@Autowired
FormModelBo boFormModel;
@Autowired
UserBo boUser;
@Autowired
FormModelBo bo;
@Autowired
RolBo boRol;
@GetMapping
public ModelAndView showRegistrationForm() {
ModelAndView mav = new ModelAndView("adminDashboard");
Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
if (!(authentication instanceof AnonymousAuthenticationToken)) {
String currentUserName = authentication.getName();
System.out.println(currentUserName);
try {
User user_complete = boUser.consultaIndividual(currentUserName);
mav.addObject("user",user_complete);
mav.addObject("permisos", boRol.consultaIndividual(user_complete.getRol().getRolId()));
mav.addObject("version", VersionReader.getVersion());
} catch (SQLException e) {
e.printStackTrace();
}
}else{
System.out.println("No user");
}
return mav;
}
}
JSP adminDashboard
通过用户信息，我获得了rol信息，并且每个rol都有模块，并打印在div＆＃34; menuZone＆＃34;所有元素都有一个onclick In Jquery。
<div class="row" id="principalDiv">
<div id="menuZone">
<c:forEach items="${user.rol.permisos}" var="permisos">
<div class="col-xs-12 col-sm-6 col-md-4 col-lg-2 iconos methodDiv" id="${permisos.permisoMetodoMap}">
<div>
<center>
<i class="fa <c:out value="${permisos.permisoMetodoIcono}" /> fa-5x" id="icon_${permisos.permisoMetodoMap}"></i>
</center>
<br>
<center>
<div>
<c:out value="${permisos.permisoNombre}" />
</div>
</center>
</div>
</div>
</c:forEach>
</div>
<div id="loadZone">
</div>
</div>
JQuery的
它使控制器请求将视图部分包含在loadZone div中。
$(document).ready(function() {
$('.methodDiv').click(function(event) {
loadAsp(this);
$('#menuZone').hide(1000);
$('#menu').addClass("fa fa-arrow-circle-left fa-3x");
});
$('#menu').click(function(event) {
$("#loadZone").hide(1000);
$("#menuZone").show(1000);
})
function loadAsp(element) {
$.get('getInclude', {
include : $(element).attr('id')
}, function(responseText) {
//alert(responseText);
$('#loadZone').html(responseText);
$("#loadZone").show(1000);
});
}
});
调度视图的控制器
@Controller
@RequestMapping(value = "/getInclude")
public class IncludesDispatcherController {
@Autowired
FormModelBo boConsultas;
@GetMapping
public ModelAndView giveIncludeByName(@RequestParam(value = "include", required = false) String include) {
ModelAndView mav;
if(include.equals("reportes")){
System.out.println(include);
return getReportesView();
}else{
System.out.println("not "+include);
return null;
}
}
public ModelAndView getReportesView() {
ModelAndView mav = new ModelAndView("includes/reportes");
try {
mav.addObject("consultas", boConsultas.consultaGeneral());
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return mav;
}
包含在loadZone div中的视图
<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%@ page isELIgnored="false"%>
<div>
<center>
<legend>
<!-- //<img alt="" src="img/pen.png"> -->
<%-- Censo Métricas Triage <br /> --%>
</legend>
</center>
</div>
<form action="${user.rol.rolMap}/createExcel" method="POST" role="form" id="">
<div class="form-group">
<!-- -------------------------------------------first section--------------------------- -->
<div class="row" style="padding-bottom: 22px !important;">
<div class="col-xs-12 col-sm-12 col-md-4 col-lg-4">
<div class="form-group">
<div class="form-group ">
<div class="input-group ">
<span class="input-group-addon">Fecha inicio ${myLogged}</span> <input type="date" id="fecha_1" name="fecha_1" />
</div>
<div class="help-block with-errors"></div>
</div>
</div>
</div>
<div class="col-xs-12 col-sm-12 col-md-4 col-lg-4">
<div class="form-group">
<div class="form-group ">
<div class="input-group ">
<span class="input-group-addon">Fecha final</span> <input type="date" id="fecha_2" name="fecha_2" />
</div>
<div class="help-block with-errors"></div>
</div>
</div>
</div>
<div class="col-xs-12 col-sm-12 col-md-4 col-lg-4">
<div class="form-group">
<div class="input-group">
<button type="submit" class="btn btn-primary">Generar Reporte</button>
</div>
<div class="help-block with-errors"></div>
</div>
</div>
</div>
</div>
</form>
<div style="padding-bottom: 22px !important;">
<table class="table">
<thead>
<tr>
<th>Nombre de médico</th>
<th>Número de consultas</th>
</tr>
</thead>
<tbody>
<c:forEach items="${consultas}" var="consultasLista">
<tr>
<td><c:out value="${consultasLista[0]} ${consultasLista[1]} ${consultasLista[2]}" /></td>
<td><c:out value="${consultasLista[3]}" /></td>
</tr>
</c:forEach>
</tbody>
</table>
</div>
在html（）时刻加载的模型变量（＆＃34; ${consultas}＆＃34;）效果很好，但我无法访问我父母的变量（＆＃34; {$user}＆＃ 34）。我知道JSP是服务器lenguaje。
所以我不知道如何做这个过程来保持它现在的灵活性。我不能分别加载视图和数据信息，首先执行一个控制器请求，另一个加载数据，然后用JQuery填充我的jsp。但是对于菜单中的所有新选项，我需要添加用于获取和填充信息的代码。
如何以良好的方式完成此过程？
