Question

我在春天有一个使用spring安全性的Web应用程序，当我尝试执行它所说的应用程序时

This webpage has a redirect loop

这是我security-context.xml之后添加此内容我得到此异常

    </b:bean>

</b:beans>

我有一个login.jsp和另外一个createContact.jsp

这是我的家庭控制器：

package com.anto.springsec.controllers;

import java.text.DateFormat;
import java.util.Date;
import java.util.Locale;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

/**
 * Handles requests for the application home page.
 */
@Controller
public class HomeController {

    private static final Logger logger = LoggerFactory.getLogger(HomeController.class);

    /**
     * Simply selects the home view to render by returning its name.
     */
    @RequestMapping(value = "/login", method = RequestMethod.GET)
    public String home(Locale locale, Model model) {
        logger.info("Welcome home! The client locale is {}.", locale);

        Date date = new Date();
        DateFormat dateFormat = DateFormat.getDateTimeInstance(DateFormat.LONG, DateFormat.LONG, locale);

        String formattedDate = dateFormat.format(date);

        model.addAttribute("serverTime", formattedDate );

        return "login";
    }

}

请帮我解决这个问题。

Answer 1

我认为intercept-url的顺序在这里很重要，而且/**模式似乎也在吞噬/login和/resources。

试试这个： -

<http pattern="/resources/**" security="none"/>
<http pattern="/login" security="none"/>

<http use-expressions="true">
    <form-login login-processing-url="/resources/j_spring_security_check"
        login-page="/login" authentication-failure-url="/login?login_error=t" />
    <logout logout-url="/resources/j_spring_security_logout" />
    <intercept-url pattern="/**" access="isAuthenticated()" />
</http>

此配置与我现有的一个项目非常相似。

这是我目前在项目中使用的配置： -

<security:http pattern="/resources/**" security="none"/>
<security:http pattern="/login" security="none"/>
<security:http pattern="/error/**" security="none"/>

<security:http auto-config="true">
    <security:form-login login-page="/login"
                         authentication-failure-url="/login?login_error=1"
                         default-target-url="/"
                         always-use-default-target="true"/>
    <security:logout logout-success-url="/"/>
    <security:intercept-url pattern="/**" access="ROLE_USER"/>
</security:http>

要在security代码中使用http属性，您需要Spring Security 3.1 ...请参阅http://static.springsource.org/spring-security/site/docs/3.1.x/reference/springsecurity-single.html#new-3.1-ns

Answer 2

试试这个

更改

<intercept-url pattern="/login*" access="permitAll()" />

到

<intercept-url pattern="/login*" access="IS_AUTHENTICATED_ANONYMOUSLY" />

或

<intercept-url pattern="/login*" access="isAnonymous()" />

如果你有表达式，我认为你必须使用isAnonymous（）

See docs

intercept-url元素，表示匿名用户可以使用任何登录页面请求。否则，请求将与模式/ **匹配，并且无法访问登录页面本身！这是一个常见的配置错误，将导致应用程序中出现无限循环。 Read more from here

该网页在spring-security应用程序中有一个重定向循环
