Question

我第一次尝试配置我的spring-security项目但是当我尝试登录时收到一条消息：＆＃34; ERR_TOO_MANY_REDIRECTS＆＃34;。可能在某个地方，它会再次重定向到管理员，但在哪里？这是我的spring-security.xml：

<?xml version="1.0" encoding="UTF-8"?>
<beans:beans xmlns="http://www.springframework.org/schema/security"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:beans="http://www.springframework.org/schema/beans"
             xsi:schemaLocation="http://www.springframework.org/schema/security

     http://www.springframework.org/schema/security/spring-security-4.0.xsd
     http://www.springframework.org/schema/beans
     http://www.springframework.org/schema/beans/spring-beans-4.1.xsd">

<http use-expressions="true" >
    <csrf disabled="true"/>
    <intercept-url pattern="/admin" access="hasRole('Admin')" />
    <intercept-url pattern="/" access="permitAll" />
    <intercept-url pattern="/logout" access="permitAll" />

    <access-denied-handler error-page="/403" />

    <form-login login-page='/login' login-processing-url="/login" authentication-failure-url="/login?error=true"
                username-parameter="username" password-parameter="password" />

    <logout logout-url="/logout" logout-success-url="/logoutSuccessful" delete-cookies="JSESSIONID" invalidate-session="true" />

</http>

<authentication-manager>
    <authentication-provider>
        <jdbc-user-service data-source-ref="myDataSource"
                           users-by-username-query= "select login, password, 'true' from employee where login=?"
                           authorities-by-username-query= "select login, role from employee where login =?  " />
    </authentication-provider>
</authentication-manager>

<beans:import resource="data-source-cfg.xml"/>
</beans:beans>

控制器类：

@Controller
@RequestMapping("/")
public class HelloController {
    @RequestMapping(method = RequestMethod.GET)
    public String printWelcome(ModelMap model) {
        return "login";
    }

    @RequestMapping(value="/admin", method = RequestMethod.GET)
    public String showAdmin(ModelMap model) {
        return "admin";
    }   


    @RequestMapping(value="/login", method=RequestMethod.GET)
    public String enter(@ModelAttribute("employee") Employee employee, ModelMap model){
        return "redirect:/admin";
    }
...

用户登录和角色的表格如下：

Employee
|id|login   |password   |first_name|last_name|mobile_phone|role   |
|1 |login1  |password1  |name1     |lname1   |phone1      |User   |
|2 |login2  |password2  |name2     |lname2   |phone2      |Admin  |

spring security version是4.0.3。这是我对spring-mvc和spring-security的第一次体验，所以这个问题可能是noobie。有什么问题？

Answer 1

问题是你只是重定向到/ login资源上的管理页面，如果他们没有登录就会发送给他们。由于/ admin需要一个特定的角色，它会尝试进入登录页面如果用户未登录，您已将其重定向回管理页面，从而创建循环。

您想要返回一个视图而不是重定向回管理页面。

配置spring-security和spring-mvc
