我们有一个网络应用,其中包含以下web.xml
:
<?xml version="1.0" encoding="UTF-8"?>
<web-app ...>
<servlet>
<servlet-name>Faces Servlet</servlet-name>
<servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.jsf</url-pattern>
</servlet-mapping>
<context-param>
<param-name>javax.faces.PROJECT_STAGE</param-name>
<param-value>Development</param-value>
</context-param>
<context-param>
<description>State saving method: 'client' or 'server' (default). See JSF Specification section 2.5.2</description>
<param-name>javax.faces.STATE_SAVING_METHOD</param-name>
<param-value>client</param-value>
</context-param>
<welcome-file-list>
<welcome-file>index.jsf</welcome-file>
<welcome-file>welcome.jsf</welcome-file>
<welcome-file>index.html</welcome-file>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<listener>
<listener-class>net.halloleo.utils.ContextListener</listener-class>
</listener>
</web-app>
我试图通过在Web应用程序的结束标记之前web.xml
的末尾添加CORS过滤器来向此Web应用程序添加CORS,
.
.
.
<listener>
<listener-class>net.halloleo.utils.ContextListener</listener-class>
</listener>
<filter>
<filter-name>CorsFilter</filter-name>
<filter-class>org.apache.catalina.filters.CorsFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>CorsFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
</web-app>
,但未为http://my.domain/data.jsp?step=3&shape=5
之类的JSP页面启用CORS。我什至通过
cors.exposed.headers
添加了默认值
<init-param>
<param-name>cors.exposed.headers</param-name>
<param-value>Access-Control-Allow-Origin,Access-Control-Allow-Credentials</param-value>
</init-param>
但这也不是更好。 -我在web.xml
中的何处放置CORS过滤器设置,以便为JSP页面提供CORS?
