[英]Spring boot: How to convert thymeleaf to jsp
我最近遵循了使用Spring Boot的身份驗證和授權教程。 它工作正常,我想將其集成到我現有的項目中。 我遵循的教程是用thymeleaf編寫的,而我當前的項目是使用jsp。 我嘗試在線搜索,但出現錯誤。
這是我的代碼:
控制者
@RequestMapping(value = { "/","/welcome" }, method = RequestMethod.GET)
public ModelAndView test() {
ModelAndView model = new ModelAndView("welcomePage");
model.addObject("title","Welcome");
model.addObject("message","This is welcome page");
return model;
}

<a th:if="${#request.userPrincipal != null}" th:href="@{/logout}">Logout</a>
JSP
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %>
<!DOCTYPE html>
<html>
<head>
<meta charset="ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<div>
<a href="/">Home</a> |
<a href="/userInfo">User Info </a> |
<a href="/admin">Admin</a> |
<c:if test="${pageContext.request.userPrincipal != null}">
<h2>Logout</h2>
<br>
</c:if>
${pageContext.request.userPrincipal}
</div>
</body>
</html>

這是我遇到的問題之一。 當我嘗試運行它時,它給了我這個錯誤。
/WEB-INF/jsp/_menu.jsp (line: [18], column: [2]) According to TLD or attribute directive in tag file, attribute [test] does not accept any expressions
這是我第一次使用。 希望你能幫助我。 非常感謝!!
在您的jsp中使用它,而不是您擁有的東西:
“ <%@ taglib前綴=” c“ uri =” http://java.sun.com/jsp/jstl/core“%>”
