我在Grails应用程序中使用Atmosphere。从我的IDE(IntelliJ Idea)运行应用程序时,一切都很好。但是当我在异常引发之后将它部署到tomcat(7.0)时:
2013-07-08 09:07:19,118 [ajp-nio-8009-exec-13] ERROR cpr.AtmosphereFramework - AtmosphereFramework exception

web.xml中的myservlet配置是:
<servlet>
<description>MeteorServlet</description>
<servlet-name>MeteorServlet</servlet-name>
<servlet-class>org.grails.plugin.platform.events.push.GrailsMeteorServlet</servlet-class>
<init-param>
<param-name>org.atmosphere.cpr.broadcaster.shareableThreadPool</param-name>
<param-value>true</param-value>
</init-param>
<init-param>
<param-name>org.atmosphere.cpr.broadcaster.maxProcessingThreads</param-name>
<param-value>20</param-value>
</init-param>
<init-param>
<param-name>org.atmosphere.cpr.broadcaster.maxAsyncWriteThreads</param-name>
<param-value>20</param-value>
</init-param>
<load-on-startup>0</load-on-startup>
<async-supported>true</async-supported>
</servlet>
用法是
var receivedOrders = new Array();
var grailsEvents = new grails.Events("${rootPath}",
{
transport: 'sse',
fallbackTransport: 'long-polling',
timeout: 10000,
onMessage: function(data){
try{
if(data.responseBody.length > 0){
var order = jQuery.parseJSON(data.responseBody).body;
if(order.id){
if (receivedOrders.indexOf(order.id) == -1) {
receivedOrders[receivedOrders.length] = order.id;
var url = "<g:createLink controller="orderAdministration" action="orderNotification"/>";
$.ajax({
type: "POST",
url: url,
data: { id: order.id }
}).done(function (response) {
if (response != "0") {
$.msgGrowl({
type: 'info', sticky: true, 'title': '${message(code: 'order.notification.title')}', 'text': response, lifetime: 5000
});
}
});
}
}
}
} catch (e) {
// Atmosphere sends commented out data to WebKit based browsers
}
}
});
grailsEvents.on('order_event', function(data){});
似乎tomcat配置有些问题。任何想法?
修改
我测试了它。但不起作用。
问题发生了,因为我在grails.Events中提供了选项。 通过改变这一点,解决了异常。
var receivedOrders = new Array();
var grailsEvents = new grails.Events("${rootPath}");
function handleOrderEvent(data){
try{
if(data.id){
if (receivedOrders.indexOf(data.id) == -1) {
receivedOrders[receivedOrders.length] = data.id;
var url = "<g:createLink controller="orderAdministration" action="orderNotification"/>";
$.ajax({
type: "POST",
url: url,
data: { id: data.id }
}).done(function (response) {
if (response != "0") {
$.msgGrowl({
type: 'info', sticky: true, 'title': '${message(code: 'order.notification.title')}', 'text': response, lifetime: 5000
});
}
});
}
}
}catch (e) {
// Atmosphere sends commented out data to WebKit based browsers
}
}
grailsEvents.on('order_event', handleOrderEvent, {transport:'long-polling', fallbackTransport:'polling'});
但仍然没有事件传播到客户端!
我在tomcat前面有一个apache webserver。在服务中但不在javascript中触发的事件。

JF Arcand(Atmospehere框架的创建者)还有另一个回复: http://atmosphere-framework.2306103.n4.nabble.com/org-apache-catalina-connector-Request-startAsync-Not-Supported-td4651994.html
您需要在web.xml中添加
<servlet-class>org.atmosphere.cpr.AtmosphereServlet</servlet-class>
<async-supported>true</async-supported>
启用Servlet 3.0,或添加
<init-param>
<param-name>org.atmosphere.useNative</param-name>
<param-value>true</param-value>
</init-param>
由于async-supported
已经定义,您应该尝试将org.atmosphere.useNative
设置为true
答案 1 :(得分:0)
通常要使Atmosphere与Tomcat一起工作(第6版 - 我对Tomcat 7不确定),我在server.xml中将连接器协议(HTTP / 1.1更改为HttpNio):
<Service name="Catalina">
<!--
<Connector port="8080" address="xxx.xxx.xxx.xxx" protocol="HTTP/1.1" ..../>
-->
<!--
HTTP 1.1 protocol is replaced with org.apache.coyote.http11.Http11NioProtocol
-->
<Connector port="8080" address="xxx.xxx.xxx.xxx" protocol="org.apache.coyote.http11.Http11NioProtocol" />
...
</Service>
也许这就是问题...
