Java中将List集合数据转成带反斜杠的字符串格式

List> trajectoryTrackList 得到数据：[{latitude=32.01813267498781, coord_type_input=wgs84, loc_time=1702505122, longitude=118.69349822755345}, {latitude=32.01816666340177, coord_type_input=wgs84, loc_time=1702505255, longitude=118.6933972171819}, {latitude=32.01817768701138, coord_type_input=wgs84, loc_time=1702505673, longitude=118.69360023714842}, {latitude=32.018234689265356, coord_type_input=wgs84, loc_time=1702505771, longitude=118.69361823829318}, {latitude=32.0181096841538, coord_type_input=wgs84, loc_time=1702505940, longitude=118.69357723563404}, {latitude=32.018234691624556, coord_type_input=wgs84, loc_time=1702506149, longitude=118.6936382402779}, {latitude=32.01829170149445, coord_type_input=wgs84, loc_time=1702506402, longitude=118.69372024778653}, {latitude=32.01930782611061, coord_type_input=wgs84, loc_time=1702506497, longitude=118.69468533391556}, {latitude=32.02103302622464, coord_type_input=wgs84, loc_time=1702506565, longitude=118.69604245744496}, {latitude=32.022917179038195, coord_type_input=wgs84, loc_time=1702506630, longitude=118.69694053633664}]
