Question

如果登录凭据无效，则显示弹出错误消息时出现问题。当我尝试使用错误的用户名或密码登录时，它只是重新加载登录页面，但没有显示错误消息。根context.xml中

我也试过

<security:http auto-config='true'>
<security:intercept-url pattern="/Admin" access="ROLE_ADMIN" />
<security:access-denied-handler error-page="/accessdenied"/>
<security:intercept-url pattern="/login" access="IS_AUTHENTICATED_ANONYMOUSLY" />
<security:intercept-url pattern="/**" access="ROLE_USER, ROLE_ADMIN" />
<security:form-login login-page='/login' default-target-url="/"authentication-failure-url="/loginfailed"/>
<security:logout logout-success-url="/" logout-url="/j_spring_security_logout"/>
</security:http>

登录控制器

@Controller
public class LoginController extends BaseController{

@RequestMapping(value="/", method = RequestMethod.GET)
public String printWelcome(ModelMap model, Principal principal ) {

String name = principal.getName();
model.addAttribute("username", name);
model.addAttribute("message", "Spring Security Custom Form example");
return "home";
}

@RequestMapping(value = "/login", method = RequestMethod.GET)
public String home(Model model) 
{
return "login";
}

@RequestMapping(value = "/loginfailed", method = RequestMethod.GET)
public String home2(Model model) 
{
model.addAttribute("error", "true");
return "login";
}

@RequestMapping(value="/logout", method = RequestMethod.GET)
public String logout(ModelMap model) {

return "login";

}

}

最后我的login.jsp

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%@ page session="true"%>
<%@ include file="include/head.jsp"%>
<body>
<%@ include file="include/login1.jsp"%>

<c:if test="${not empty error}">
<div class="errorblock">
Your login attempt was not successful, try again.<br /> Caused :
${sessionScope["SPRING_SECURITY_LAST_EXCEPTION"].message}
</div>
</c:if>

</body>
</html>

Answer 1

spring security在身份验证失败的情况下发送重定向 =＆gt; SPRING_SECURITY_LAST_EXCEPTION处理程序中不再提供/loginfailed请求属性，因为它是新请求。

但是spring将包含消息的error参数添加到重定向。您还可以实现自定义AuthenticatinoFailureHandler

SimpleUrlAuthenticationFailureHandler

Spring安全性不显示错误消息
