显示自定义页面时出现java Spring安全错误
我正在研究Spring安全集成, 我的内置安全页面应用程序运行良好。 但对于自定义登录页面,它的给出错误
The localhost page isn’t working
这是我的代码供参考
春季安全内部。xml
<http use-expressions="true">
>
<intercept-url pattern="/**" access="isAuthenticated()"/> <!-- this means all URL in this app will be checked if user is authenticated -->
<form-login
login-page="/login"
default-target-url="/"
authentication-failure-url="/login?error"
username-parameter="username"
password-parameter="password" />
<logout logout-url="/logout" logout-success-url="/"/> <!-- the logout url we will use in JSP -->
</http>
在登录中。jsp
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<html>
<head>
<title>Custom Login Page</title>
</head>
<body onload='document.loginForm.j_username.focus();'>
<h3>Custom Login Page</h3>
<%
String errorString = (String)request.getAttribute("error");
if(errorString != null && errorString.trim().equals("true")){
out.println("Incorrect login name or password. Please retry using correct login name and password.");
}
%>
<form name='loginForm' action="<c:url value='j_spring_security_check' />"
method='POST'>
<table>
<tr>
<td>User:</td>
<td><input type='text' name='j_username' value=''>
</td>
</tr>
<tr>
<td>Password:</td>
<td><input type='password' name='j_password' />
</td>
</tr>
<tr>
<td><input name="submit" type="submit"
value="submit" />
</td>
<td><input name="reset" type="reset" />
</td>
</tr>
</table>
</form>
</body>
</html>
在控制器中:
@RequestMapping(value = "/login", method = RequestMethod.GET)
public ModelAndView login(ModelMap mode,
@RequestParam(value = "error", required = false) String error,
@RequestParam(value = "logout", required = false) String logout) {
System.out.println("\n\t -------------");
ModelAndView model = new ModelAndView("login");
if (error != null) {
model.addObject("error", "Invalid username and password!");
}
if (logout != null) {
model.addObject("msg", "You've been logged out successfully.");
}
return model;
}
当我使用内置形式的pulgin运行项目时,url是
http://localhost:8080/SpringMvcSecurity/spring_security_login
登录后如果我手动点击网址
http://localhost:8080/SpringMvcSecurity/login
它显示了登录页面 但是我不知道如果页面这次显示,那么为什么它没有在自定义配置中显示。 请帮忙
谢谢沙辛 有4个变化
- Need to change the url name in RequestMapping url for ex:customlogin
- same name need to replace in spring-security.xml
- add line in spring-security.xml
- replace the username password attribute names, the way those appears in jsp page.
<intercept-url pattern="/customlogin" access="permitAll" />
# 1 楼答案
这是因为你有你的
@RequestMapping
值和。jsp名称为login
。至少更改一个,如下所示在你的配置中
