spring - 无法使用 Spring Security 评估表达式

Question

我有一个 Spring 休息服务，我正在尝试为其添加安全性。我关注了this tutorial ，但是当我尝试直接访问该服务时，出现以下错误:

There was an unexpected error (type=Internal Server Error, status=500). Failed to evaluate expression 'ROLE_USER'

这是我的安全配置:

webSecurityConfig.xml

<http entry-point-ref="restAuthenticationEntryPoint">
      <intercept-url pattern="/**" access="ROLE_USER"/>

      <form-login
         authentication-success-handler-ref="mySuccessHandler"
         authentication-failure-handler-ref="myFailureHandler"
      />

      <logout />
   </http>

   <beans:bean id="mySuccessHandler"
      class="com.eficid.cloud.security.rest.AuthenticationSuccessHandler"/>
   <beans:bean id="myFailureHandler" class=
     "org.springframework.security.web.authentication.SimpleUrlAuthenticationFailureHandler"/>


      <authentication-manager>
        <authentication-provider>
          <user-service>
            <user name="temp" password="temp" authorities="ROLE_USER" />
          </user-service>
        </authentication-provider>
      </authentication-manager> 

SpringSecurityConfig:

public class SpringSecurityConfig {

    public SpringSecurityConfig() {
        super();
    }

}

我在尝试使用curl登录时也遇到此错误:

{
"timestamp":1460399841286,
"status":403,"error":"Forbidden",
"message":"Could not verify the provided CSRF token because your session was not found.",
"path":"/spring-security-rest/login"
}

我需要手动将 csrf token 添加到命令中吗？该服务有一个自签名证书(如果有什么不同的话)。

如果您不需要启用 CRF，则可以在 webSecurityConfig.xml 文件中禁用它，如下所示:

        <http auto-config="true" use-expressions="true">
        <intercept-url pattern="/login.html" access="hasRole('ANONYMOUS')" />
        <intercept-url pattern="/**" access="hasRole('ROLE_USER')"/>
        <!-- This form is a default form that used to login  
            <http-basic/>
         -->
         <form-login login-page="/login.html"/>
         <csrf disabled="true"/>
    </http>

如果启用了 CSRF，您必须在要登录或注销的页面中包含 _csrf.token。以下代码需要添加到表单中:

<input type="hidden" name="${_csrf.parameterName}"
            value="${_csrf.token}" />
