问题描述
我有以下拦截器类:
package cz.coffeeexperts.feedback.server.web.interceptors;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.handler.HandlerInterceptorAdapter;
public class RestAuthorizationInterceptor extends HandlerInterceptorAdapter {
@Override
public boolean preHandle(HttpServletRequest request,
HttpServletResponse response, Object handler)
throws Exception {
System.out.println("fuu");
response.setStatus( HttpServletResponse.SC_UNAUTHORIZED );
return false;
}
}
我在spring-webmvc.xml中对其进行了如下配置:
I configured it inside my spring-webmvc.xml as following :
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="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 http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd">
<mvc:annotation-driven/>
<mvc:interceptors>
<mvc:interceptor>
<mvc:mapping path="/rest/api/01/status" />
<bean class="cz.coffeeexperts.feedback.server.web.interceptors.RestAuthorizationInterceptor" />
</mvc:interceptor>
</mvc:interceptors>
</beans>
但是,当我转到http://localhost:8080/myserver/rest/api/01/status
时,会得到状态码为200的常规答案(与添加拦截器之前相同).另外,不会打印消息"fuu"(因此不会调用preHandle方法).
However when I go to http://localhost:8080/myserver/rest/api/01/status
, I get regular answer with status code 200 (same as before I added interceptor). Also, message "fuu" is not printed (so the preHandle method is not called).
有什么想法吗?我从以下示例开始进行操作: http://javapapers.com/spring/spring -mvc-handler-interceptor/,但是所有其他示例看起来都一样,我找不到哪里出了错.
Any ideas? I started to do it with this example : http://javapapers.com/spring/spring-mvc-handler-interceptor/, but all other examples look the same, I cant find where I go wrong.
我正在使用Spring 3.2.4.RELEASE
I am using Spring 3.2.4.RELEASE
重要的修改,可与此配合使用:
Important edit, it works with this :
<mvc:interceptors>
<mvc:interceptor>
<mvc:mapping path="/**" />
<bean class="cz.coffeeexperts.feedback.server.web.interceptors.RestAuthorizationInterceptor" />
</mvc:interceptor>
</mvc:interceptors>
所以问题是,我的路径出了什么问题?
So the question is, what is wrong with my path?
推荐答案
好,我找到了解决方案,因为我的路径是用以下命令定义的:
Ok, I found solution, because my path is defined with following :
<servlet-mapping>
<servlet-name>rest</servlet-name>
<url-pattern>/rest/*</url-pattern>
</servlet-mapping>
这就是我的控制器的外观
And this is how my controller looks like
@Controller
@RequestMapping(value = "/api")
public class ApiController {
@RequestMapping(value = "/01/status", method = RequestMethod.GET)
@ResponseBody
public ServerStatusJSON getStatus(HttpServletResponse response) {
...
}
}
此地址http://localhost:8080/myserver/rest/api/01/status
的工作配置如下:
The working configuration for this address : http://localhost:8080/myserver/rest/api/01/status
is as following :
<mvc:interceptors>
<mvc:interceptor>
<mvc:mapping path="/api/01/status" />
<bean class="cz.coffeeexperts.feedback.server.web.interceptors.RestAuthorizationInterceptor" />
</mvc:interceptor>
</mvc:interceptors>
