spring-security - Spring 安全 : Getting error "The server understood the request but refuses to authorize it"

Question

使用 Spring Security 运行应用程序时，我在所有浏览器上都遇到以下错误:

"The server understood the request but refuses to authorize it"

我尝试在“spring-security.xml”文件中将角色从“ROLE_ADMIN”更改为“ROLE_USER”。

下面是“spring-security.xml”

<http auto-config="true">
    <intercept-url pattern ="/admin" access = "hasRole('ROLE-USER')"/>
    </http>
    <authentication-manager>
        <authentication-provider>
        <user-service>
            <user name = "abc" password = "xyz" authorities="hasRole('ROLE-USER')" />
        </user-service>
        </authentication-provider>
    </authentication-manager>

下面是 SpringController 类:

@Controller
public class SpringController {



@RequestMapping(value = "/")
    public String homePage() {
        return "HomePage";
    }
    @RequestMapping(value="/admin", method=RequestMethod.GET)
    public String loginPage() {
        return "login";
}

HomePage.jsp 和 login.jsp 页面已加载属性，但在 login.jsp 上传递凭据后出现错误:

HTTP Status 403 – Forbidden

---

Type: Status Report

Message: Access is denied

Description: The server understood the request but refuses to authorize it.

403 是一个非常通用的错误代码。我遇到了同样的问题，但在进行了一些更改后，我能够使其正常工作。仍然不确定问题是密码加密还是表单登录标签的配置。

<security:http auto-config="true"  >
        <security:intercept-url pattern="/login*" access="isAnonymous()" />
        <security:intercept-url pattern="/**" access="isAuthenticated()"/>
        <security:form-login login-page="/login" login-processing-url="/login-user" authentication-failure-url="/login?error=true" />
        <security:csrf disabled="true" />
        <security:logout logout-success-url="/"  />
    </security:http>

    <security:authentication-manager>
        <security:authentication-provider>
            <security:user-service>
                <security:user name="admin" password="{noop}admin" authorities="ROLE_USER" />
            </security:user-service>
        </security:authentication-provider  >

    </security:authentication-manager>

忽略标签中的 security: 前缀。

密码前面的 {noop} 确保我没有对密码使用任何加密。

Controller 显示登录 JSP

@Controller
@RequestMapping("/login")
public class LoginController {

    @RequestMapping(value = { "/", "" }, method = { RequestMethod.GET})
    public String login(HttpServletRequest request) {
        System.out.println("LoginController.login() "+request.getRequestURI());
        return "login";
    }

}

表单操作

<form name='loginForm' action="login-user" method='POST'>
