我有一个spring-boot应用。
在我的依赖项中，我有：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
我有controller：
@Controller
public class LoginPageController {
@RequestMapping("/login")
public String loginPage(Model model) {
return "login";
}
}
在application.properties我有：
spring.thymeleaf.cache=false
spring.thymeleaf.enabled=true
spring.thymeleaf.prefix=classpath:/templates/
spring.thymeleaf.suffix=.jsp
我还有一个文件resources/templates/login.jsp。
<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>
<%
String queryString;
String service = request.getParameter("service");
String type = request.getParameter("type");
if (type != null) {
queryString = "service=" + service + "&type=" + type;
} else {
queryString = "service=" + service;
}
%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8"/>
<title>Login</title>
</head>
<body>
<h3>Login Page</h3>
<p style="color: red;">${errorString}</p>
<form method="POST" action="${pageContext.request.contextPath}/login?<%=queryString%>">
<input type="hidden" name="redirectId" value="${param.redirectId}" />
<table border="0">
<tr>
<td>User Name</td>
<td><input type="text" name="userid" value="" /> </td>
</tr>
<tr>
<td>Password</td>
<td><input type="password" name="password" value= "" /> </td>
</tr>
<tr>
<td colspan ="2">
<input type="submit" value= "Submit" />
<a href="${pageContext.request.contextPath}/">Cancel</a>
</td>
</tr>
</table>
</form>
<p style="color:blue;">Login with:</p>
<text>employee1/123</text> </br>
<text>manager1/123</text>
</body>
</html>
但是当我尝试加载login.jsp时，会发生异常。
