我的Spring控制器中有一个post方法,它接受一个名为wkt
的请求参数。这是我的方法签名:
@RequestMapping(value="/getNumberOfProperties", method=RequestMethod.POST)
public String getEstimateForNumberOfProperties(@RequestParam("wkt") String wkt) {
//code
}
在我的jQuery中,我这样调用这个方法。
$.post(webroot + "/project/getNumberOfProperties", {wkt : wktGeomFromServer})
这很有效。但是,对于那些太长的wkt字符串,我收到了这个错误。

那么多久太久了?在做了一些测试后,我发现如果字符串的长度为1,971,324 or less
,一切正常。否则,我得到上述异常。我不知道这是用Spring还是tomcat等。另外,我已经用Chrome验证过wkt参数在所有情况下都会被发送,无论长度如何。因此Spring错误消息太长时间对我来说没有多大意义。某处是1,971,324
某个神奇数字吗?
有什么建议吗?
答案 0 :(得分:1)
可能是服务器配置问题?例如,默认情况下,Tomcat的最大发布请求内容大小为2MB。
