我正在开发一个Spring-MVC后端(和GWT前端),它提供了一个REST接口。出于安全原因,它应该在每个请求上验证令牌。现在的问题是:如何在不写入应该检查它的每个控制器内部的情况下检查该令牌?我想到一个类,其方法在请求到达负责的控制器之前运行并检查令牌,如果它有效,它会将数据传递给控制器。
通过网络发送的JSON数据如下所示:
{
"data":
{
"id":1,
"firstName":"firstExample",
"lastName":"lastExample"
},
"csrf":"myCSRFToken"
}
我的Spring设置的其余部分如下所示:
的web.xml:
<context-param>
<param-name>contextClass</param-name>
<param-value>org.springframework.web.context.support.AnnotationConfigWebApplicationContext</param-value>
</context-param>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>myapp.server.AppConfig</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<servlet>
<servlet-name>dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/rest/*</url-pattern>
</servlet-mapping>
调度-servlet.xml中:
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd">
<context:component-scan base-package="myapp.server.controller" />
<mvc:annotation-driven />
</beans>
AppConfig.java:
@Configuration
@EnableWebMvc
public class AppConfig {
//
}
PersonController:
@Controller
@RequestMapping("/persons")
public class PersonController {
@ResponseBody
@RequestMapping(method = RequestMethod.GET)
public Collection<Person> list() {
//
}
}
所以基本的想法是,我的CSRFCheck.java类将首先接收每个请求。它将检查CSRF-Token,并将JSON的“data”部分的内容转发给负责的控制器。所以控制器只会收到:
{
"id":1,
"firstName":"firstExample",
"lastName":"lastExample"
}
我是Spring的新手,我想知道在哪里修改配置,以便按预期工作。
谢谢!
现在正在使用dispatcher-servlet.xml中的代码:
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd">
<context:component-scan base-package="myapp.server.controller" />
<mvc:annotation-driven />
<mvc:interceptors>
<bean class="myapp.server.XSRFInterceptor" />
</mvc:interceptors>
</beans>
但为什么不使用这个AppConfig.java?:
@Configuration
@EnableWebMvc
@ComponentScan(basePackages="myapp.server.controller")
public class AppConfig extends WebMvcConfigurerAdapter {
@Override
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(new XSRFInterceptor());
}
}
还有一个问题:如何修改传递给控制器的JSON?
解决问题1(xml与java):
调度-servlet.xml中:
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd">
</beans>
上面的AppConfig.java
CSRFInterceptor.java:
@Component
public class CSRFInterceptor extends HandlerInterceptorAdapter {
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
// Some code
return true;
}
}
仍然要解决:我如何处理拦截器内的JSON数据?
