How to convert list of map as string to list of Map<String,String> or list<Pojo>

Question

i have a string "[{id=123, customername=john}]" i want to convert it into List<Map<String,String>> or List<Pojo> , i tried using gson library to convert into List<Map<String,String>> but Method threw 'com.google.gson.JsonSyntaxException' exception as gson accepts first argument as json string and this is not a json string, i can convert into json string and pass to gson function or object mapper function with use of pattern, just want to avoid that , is there any way to convert the string into List<Map<String,String>> or List class, i also followed the thread how to convert below string to list of map? but this throws com.google.gson.JsonSyntaxException
