将web前端JS错误日志合并到logback中再一起汇总到mysql或其他

在java后台中 我们可以通过logback 来记录日志，便于线上问题排查；

/**
* 收集前端错误日志
window.onerror = function(errorMessage, scriptURI, lineNumber,columnNumber,errorObj)  {
var img = new Image();
img.src = _PATH + '/sendJSError?errorMessage=' + encodeURIComponent(errorMessage) + '&scriptURI=' + encodeURIComponent(scriptURI) +
'&lineNumber=' + lineNumber + '&columnNumber=' + columnNumber + '&errorObj=' + encodeURIComponent(errorObj);
};
*
* @param {String} errorMessage 错误信息
* @param {String} scriptURI   出错的文件
* @param {Long}  lineNumber   出错代码的行号
* @param {Long}  columnNumber 出错代码的列号
* @param {Object} errorObj    错误的详细信息，Anything
*/
@RequestMapping("sendJSError")
@ResponseBody
public String sendJSError(String errorMessage,String scriptURI,String lineNumber,String columnNumber,String errorObj) {
StringBuilder message = new StringBuilder();
message.append("错误信息：" + errorMessage);
message.append("出错文件：" + scriptURI);
message.append("出错行号：" + lineNumber);
message.append("出错列号：" + columnNumber);
message.append("错误详情：" + errorObj);
BaseLog.e(IndexCtrl.class, message.toString());
return "";
}
