Java Spring和CORS [英] Java Spring and CORS

问题描述

我需要创建一组web服务，这将由javascript从其他域请求。

我有foud，有一个很酷的包支持跨-domain：CORSFilter。

我看到CORS的实现是通过添加到web.xml中：

 < web-app> 
< filter> 
< filter-name> CORSFilter< / filter-name> 
< filter-class> CORSFilter< / filter-class> 
< / filter> 
< filter-mapping> 
< filter-name> CORSFilter< / filter-name> 
< url-pattern> / api / *< / url-pattern> 
< / filter-mapping> 
  

自己的配置：

 < web-app version =2.5xmlns =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\"> 
 
<！ - 所有Servlet和过滤器共享的根弹簧容器的定义 - > 
< context-param> 
< param-name> contextConfigLocation< / param-name> 
< param-value> /WEB-INF/spring/root-context.xml< / param-value> 
< / context-param> 
 
<！ - 创建所有Servlet和过滤器共享的Spring容器 - > 
< listener> 
< listener-class> org.springframework.web.context.ContextLoaderListener< / listener-class> 
< / listener> 
 
<！ - 处理应用程序请求 - > 
< servlet> 
< servlet-name> appServlet< / servlet-name> 
< servlet-class> org.springframework.web.servlet.DispatcherServlet< / servlet-class> 
< init-param> 
< param-name> contextConfigLocation< / param-name> 
< param-value> /WEB-INF/spring/appServlet/servlet-context.xml< / param-value> 
< / init-param> 
< load-on-startup> 1< / load-on-startup> 
< / servlet> 
 
< servlet-mapping> 
< servlet-name> appServlet< / servlet-name> 
< url-pattern> / *< / url-pattern> 
< / servlet-mapping> 
 
 
 
< / web-app> 
  

当我试图添加CORS配置到我的web.xml：

 < web-app version =2.5xmlns =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\">

<！ - 创建所有Servlet和过滤器共享的Spring容器 - >

您应该考虑使用  -framework-4-2-goes-garel =nofollow> Spring Framework 4.2 GA 。有关详情，请参见此博文。 / p> 
 
 
如果您喜欢继续使用基于 Filter 的方法，例如，如果您不使用Spring MVC， ，春季  CorsFilter  。
 
I need to create pack of webservices, which will be requestet by javascript from other domains.

I've foud, that there is a cool package for support cross-domain: CORSFilter.

I saw, that the implementation of CORS is by add to web.xml:
<web-app>
<filter>
    <filter-name>CORSFilter</filter-name>
    <filter-class>CORSFilter</filter-class>
</filter>
<filter-mapping>
    <filter-name>CORSFilter</filter-name>
    <url-pattern>/api/*</url-pattern>
</filter-mapping>


But i've got my own configuration:
<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</param-value>
    </context-param>

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

    <servlet-mapping>
        <servlet-name>appServlet</servlet-name>
        <url-pattern>/*</url-pattern>
    </servlet-mapping>



</web-app>
When i'm trying to add CORS configuration to my web.xml:
<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</param-value>
</context-param>

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

<servlet-mapping>
    <servlet-name>appServlet</servlet-name>
    <url-pattern>/*</url-pattern>
</servlet-mapping>

<filter>
    <filter-name>corsFilter</filter-name>
    <filter-class>com.thetransactioncompany.cors.CORSFilter</filter-class>
</filter>

<filter-mapping>
    <filter-name>corsFilter</filter-name>
    <servlet-name>/*</servlet-name>
</filter-mapping>


I get an error:
    mar 19, 2013 2:17:08 PM org.apache.catalina.core.StandardContext startInternal
SEVERE: Error filterStart
mar 19, 2013 2:17:08 PM org.apache.catalina.core.StandardContext startInternal
SEVERE: Context [] startup failed due to previous errors
How i should implement it ?

Thanks
解决方案
You should maybe consider using the native CORS support available as of Spring Framework 4.2 GA. See this blog post for more details.

If you prefer continuing using a Filter based approach, for example if you are not using Spring MVC but just Spring Web, a Spring CorsFilter is also provided.
