这个有bug,最近比较忙,没有把最新的上传,你可以使用如下配置来修正
你可以把spring-mvc.xml的
<mvc:async-support default-timeout="35000" task-executor="executor"/>
超时时间设置的比 js中稍微长点 这样我测了下没有503了;
js 我稍微改了下
var timeout = 30 * 1000;
var defaultRetryTime = 10 * 1000;
var retryTime = defaultRetryTime;
var pollingUrl = ctx + "/admin/polling";
var longPolling = function(url, callback) {
$.ajax({
url: url,
async: true,
cache: false,
global: false,
timeout: timeout,
dataType : "json"
}).done(function(data, status, request) {
callback(data);
data = null;
status = null;
request = null;
var currentRetryTime = 0;
setTimeout(
function () {
longPolling(url, callback);
},
currentRetryTime
);
}).fail(function(jqXHR, textStatus, errorThrown) {
jqXHR = null;
textStatus = null;
errorThrown = null;
var currentRetryTime = 0;
if(textStatus == 'error' || textStatus == 'parsererror') {
retryTime = retryTime * 2;
if(retryTime >= 1000 * 1000) {
retryTime = defaultRetryTime;
}
}
setTimeout(
function () {
longPolling(url, callback);
},
currentRetryTime
);
});
};
如果是error 那么重试时间是递增的;否则比如timeout 直接重试 不暂停(否则可能有延迟) 就像之前说的
from es.
(function getMessages() {
$.ajax(
{
dataType : "json",
url : 'getMessages',
cache : false,
success : function(data) {
//do something
}
}).always(function() {
getMessages();
});
})();
这样的方式不知道是否可行,

为了防止 http status 非 200 , (也就是我个人看个debug控制台请求红色特别扭, 强迫症 呵呵)
dr.onTimeout(new Runnable() {
@Override
public void run() {
// TODO Auto-generated method stub
}
});
我有空就看看java , 借鉴涛哥的代码复习+学习.

记录那个红色的部分是浏览器完成的,咱控制不了
