为了让所有请求都支持跨域，我是这样做的：

web.xml中：

<servlet>
   <servlet-name>dispatcher</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>
       <init-param>
           <param-name>dispatchOptionsRequest</param-name>
           <param-value>true</param-value>
       </init-param>
       <load-on-startup>1</load-on-startup>
</servlet>

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

自己的代码里：

public class Constants {
    public static String ODIN_CROSS_DOMAIN_ORIGIN = "http://xxxxxx.wandoulabs.com";
    public static String ODIN_CROSS_DOMAIN_CREDENTIALS = "true";
    public static String ODIN_CROSS_DOMAIN_METHODS = "GET,PUT,POST,DELETE,OPTIONS";
    public static String ODIN_CROSS_DOMAIN_HEADERS = "Referer,Accept,Origin,User-Agent,content-type";
}

@RequestMapping(value = "/{[a-z]+}", method = RequestMethod.OPTIONS)
public void commonOptions(HttpServletResponse theHttpServletResponse) throws IOException {
    theHttpServletResponse.setHeader("Access-Control-Allow-Methods", Constants.ODIN_CROSS_DOMAIN_METHODS);
    theHttpServletResponse.setHeader("Access-Control-Allow-Headers", Constants.ODIN_CROSS_DOMAIN_HEADERS);
    theHttpServletResponse.setHeader("Access-Control-Allow-Origin", Constants.ODIN_CROSS_DOMAIN_ORIGIN);
    theHttpServletResponse.setHeader("Access-Control-Allow-Credentials",Constants.ODIN_CROSS_DOMAIN_CREDENTIALS);
}
