当用使用ssh框架,前端用到kindeitor富文本编辑器时候,上传文件后有一个图片管理.当点击图片管理的时候,在后台会报一个异常:

这个异常是由于kindeditor为了避免浏览器缓存,于是在后台链接里面加上了当前时间,作为一个参数传递.
而struts2框架对于这个传递过来的string类型的数据(其实应该是long类型的),解析成了integer类型的数据了,所以就会报解析异常.因为long类型的数当长度大于int类型的话,就会报一个转换异常.而struts2就会报一个解析异常.
解决办法:
在防止string类型数据被解析,修改一下传递的数据url.
在kindeditor源文件里面,找到filemanager.js文件,修改其中的第75行代码,
function reloadPage(path, order, func) {
var param = 'path=' + path + '&order=' + order + '&dir=' + dirName;
dialog.showLoading(self.lang('ajaxLoading'));
K.ajax(K.addParam(fileManagerJson, param + '&' + new Date().getTime()), function(data) {
dialog.hideLoading();
func(data);
});
}
把原先的fileManagerJson, param + ‘&’ + new Date().getTime()这个代码中’&’字符后面加一个’=’等号即可
示例代码
function reloadPage(path, order, func) {
var param = 'path=' + path + '&order=' + order + '&dir=' + dirName;
dialog.showLoading(self.lang('ajaxLoading'));
K.ajax(K.addParam(fileManagerJson, param + '&=' + new Date().getTime()), function(data) {
dialog.hideLoading();
func(data);
});
}
fileManagerJson, param + ‘&=’ + new Date().getTime().
有效避免struts去解析字符串
亲测有效
