为休息服务构建Spring安全拦截器

标签： java spring spring-mvc spring-security

我有一个基本的REST服务，它公开了基于Spring MVC和@RestController机制的各种API。现在我正在尝试为Spring安全性添加一个拦截器，以便在访问任何其他请求之前要求登录（通过特定的REST请求）。我们的想法是拦截器检查请求的活动会话，如果找不到活动登录，则将其指向登录服务。如果找到活动登录，则拦截器会将请求传递到正确的URL。 我一直在玩XML文件，但我不断得到的是重定向循环。 :(值得注意的是，我根本没有与此服务器关联的视图。访问是通过我无法访问的GUI的http请求完成的。

到目前为止，这是我的配置： web.xml中：

    <?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

    <!-- The definition of the Root Spring Container shared by all Servlets and Filters -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/spring/root-context.xml, /WEB-INF/spring/application-security.xml</param-value>
    </context-param>

    <filter>
<filter-name>springSecurityFilterChain</filter-name>
<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>

<filter-mapping>
<filter-name>springSecurityFilterChain</filter-name>
<url-pattern>/aisrv/*</url-pattern>
</filter-mapping>

    <!-- Creates the Spring Container shared by all Servlets and Filters -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <!-- Processes application requests -->
    <servlet>
        <servlet-name>aisrvServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>/WEB-INF/spring/aisrvServlet/servlet-context.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>aisrvServlet</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

</web-app>

Servlet的context.xml中

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

    <!-- DispatcherServlet Context: defines this servlet's request-processing infrastructure -->

    <!-- Enables the Spring MVC @Controller programming model -->
    <annotation-driven />

    <!-- Handles HTTP GET requests for /resources/** by efficiently serving up static resources in the ${webappRoot}/resources directory -->
    <resources mapping="/resources/**" location="/resources/" />

    <!-- Resolves views selected for rendering by @Controllers to .jsp resources in the /WEB-INF/views directory -->
    <beans:bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <beans:property name="prefix" value="/WEB-INF/views/" />
        <beans:property name="suffix" value=".jsp" />
    </beans:bean>

    <context:component-scan base-package="com.bmc.ai.server" />
    <!--- Specific beans for my server -->
</beans:beans>

应用security.xml文件：

<?xml version="1.0" encoding="UTF-8"?>
<beans:beans xmlns="http://www.springframework.org/schema/security"
    xmlns:beans="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-3.2.xsd 
    http://www.springframework.org/schema/security 
    http://www.springframework.org/schema/security/spring-security-3.2.xsd">

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

    <http auto-config="true" use-expressions="true">
   <!--       <intercept-url pattern="/login" access="ROLE_ADMIN" /> -->

  <!--       <intercept-url pattern="/logout" access="permitAll" />
        <intercept-url pattern="/accessdenied" access="permitAll" /> -->

        <intercept-url pattern="/**" access="ROLE_USER" requires-channel="https"/>
<!--          <http-basic /> -->
         <form-login default-target-url="/test"  /> 
   <!--     <logout logout-success-url="/logout" />  -->
    </http>

    <authentication-manager alias="authenticationManager">
        <authentication-provider>
            <user-service>
                <user name="user" password="123" authorities="ROLE_USER" />
            </user-service>
        </authentication-provider>
    </authentication-manager>

</beans:beans>

我确信这是非常基本且容易修复的东西，但我似乎无法找到我的手和腿。任何帮助将不胜感激。

============ EDIT ======================= 按照Varun的例子，我修改了我的application-security.xml，如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<beans:beans xmlns="http://www.springframework.org/schema/security"
    xmlns:beans="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-3.2.xsd 
    http://www.springframework.org/schema/security 
    http://www.springframework.org/schema/security/spring-security-3.2.xsd">

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

     <http auto-config="true" use-expressions="true">
  <!-- other filters -->
  <custom-filter ref="myCustomFilter" before="SESSION_MANAGEMENT_FILTER" />  
    <intercept-url pattern="/**" access="ROLE_USER" requires-channel="https"/>
</http>


<beans:bean id="myCustomFilter" class="com.company.server.impl.security.RestFilter">

</beans:bean>


<!--     <http auto-config="true" use-expressions="true">
         <intercept-url pattern="/login" access="ROLE_ADMIN" />

        <intercept-url pattern="/logout" access="permitAll" />
        <intercept-url pattern="/accessdenied" access="permitAll" />

        <intercept-url pattern="/**" access="ROLE_USER" requires-channel="https"/>
         <http-basic />
         <form-login default-target-url="/test"  /> 
       <logout logout-success-url="/logout" /> 
    </http>-->

    <authentication-manager alias="authenticationManager">
        <authentication-provider>
            <user-service>
                <user name="user" password="123" authorities="ROLE_USER" />
            </user-service>
        </authentication-provider>
    </authentication-manager>

</beans:beans>

并添加了以下RestFiletClass：

import java.io.IOException;

import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;

import org.springframework.web.filter.GenericFilterBean;

import com.company.server.controller.ExcpetionHandling.GenericErrorExeception;
import com.company.server.interfaces.comm.ICorbaClient;

public class RestFilter extends GenericFilterBean {

    @Override
    public void doFilter(ServletRequest req, ServletResponse res,
            FilterChain chain) throws IOException, ServletException {

         HttpServletResponse response = ((HttpServletResponse) res);
            HttpServletRequest request = ((HttpServletRequest) req);
            ICorbaClient corba = (ICorbaClient)request.getSession().getAttribute("corba");
            if(corba.getSuccessfulLogin()){
                System.out.println("Authorized through filter");
                chain.doFilter(req, res);
            }else{
                throw new GenericErrorExeception("User unauthorized", null, HttpServletResponse.SC_UNAUTHORIZED);
            }
    }

}

但是，Spring似乎完全跳过了过滤器。我需要在某处添加它还是用它做更多的事情？

答案 0 :(得分：2)

您需要在spring security xml中添加自定义过滤器。在下面的示例中，已经修改了预构建的过滤器，但您可以将类检出作为参考来构建自己的过滤器。

<http use-expressions="true">
  <!-- other filters -->
  <custom-filter ref="myCustomFilter" before="SESSION_MANAGEMENT_FILTER" />  
</http>


<beans:bean id="myCustomFilter" class="com.mycompany.RestFilter">

</beans:bean>

public class RestFilter extends GenericFilterBean {

   // @Override of Filter.doFilter() method
   @Override
   public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) {
      // Implement
   }
}

Spring安全性会在预定义的SESSION_MANAGEMENT_FILTER之前自动调用此过滤器并运行您的代码。
