如何在Spring MVC中渲染部分视图
我想在我的jsp视图页面中包含一个局部视图。 我怎样才能做到这一点？ 我想将我的“addEmployeeContacts.jsp”添加到“addEmployee.jsp”页面。 addEmployee.jsp <%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%> <%@ taglib prefix="form" uri="http://www.springframework.org/tags/form" %> <%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %> Insert title here
添加员工
名字：姓氏： <tr>
<td>Date of Birth:</td>
<td><form:input path="dob" type="date"/></td>
</tr>
<tr>
<td colspan="2">
<input type="submit" value="Add Employee">
</td>
</tr>
</table>
</form:form>
<div>
<jsp:include page="addEmployeeContacts.jsp">
${employeeContacts}
</jsp:include>
</div>
</body>
</html>
</code>
和addEmployeeContacts.jsp
<code>
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<h1>Add Employee</h1>
<form:form commandName="employeeContacts">
<table>
<tr>
<td>Contact Type</td>
<td><form:input path="contactType"/></td>
</tr>
<tr>

<td><form:input path="contactValue"/></td>
</tr>
<tr>
<td colspan="2">
<input type="submit" value="Add Contacts">
</td>
</tr>
</table>
</form:form>
</body>
</html>
</code>
addEmployeeContactController

}
@RequestMapping(value="/addEmployeeContacts", method=RequestMethod.POST)
public String addEmployeeContacts(@ModelAttribute("employeeContacts") EmployeeContacts employeeContacts,HttpSession session,BindingResult result){
if(result.hasErrors()){
System.out.println(result);
return "addEmployeeContacts";
}
else{
Employee employee = (Employee)session.getAttribute("employee");
employeeContacts.setEmployee(employee);
employeeContactService.save(employeeContacts);
}
return "redirect:index.jsp";
}
}
投掷错误
org.apache.jasper.JasperException：java.lang.IllegalStateException：BindingResult和bean名称'employeeContacts'的普通目标对象均不可用作为请求属性
如果您的localhost：8080 / EmployeeManagement / addEmployee.html直接将您置于addEmployee.jsp中，原因是我没有在您的帖子中看到映射，那么您需要在jsp中执行以下操作。 这应该向您的控制器请求获取包含的视图。 希望这可以帮助。
<div>
<jsp:include page="/addEmployeeContacts">
${employeeContacts}
</jsp:include>
</div>
您需要使用.tag作为主页面和局部视图作为.jsp
例如：
像这样创建Layout.tag
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@ taglib prefix="spring" uri="http://www.springframework.org/tags"%>
<%@tag description="Overall Page template" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<title>Home</title>
</head>
<body>
<section class="content">
<jsp:doBody />
</section>
</body>
</html>
然后像这样创建一个局部视图
<%@taglib prefix="t" tagdir="/WEB-INF/tags/"%>
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@ taglib prefix="spring" uri="http://www.springframework.org/tags"%>
<t:Layout>
<div>
your partial view html content
</div>
</t:Layout>
