发生异常时继续处理

Question

I have the below code that basically reads a bunch of JSON strings, and converts them to a java object. My problem is if at any point, the transformation fails for any of the JSON strings, it doesn't process the others strings. What I need is -

1. Find the string for which the error occured.
2. In the exception block do something to continue processing.

Here is my code to convert from JSON to Java.

public static <T> T convertToObject(String jsonString,Class<T> classType){
    T obj = null;
    try {
        obj = objectMapper.readValue(jsonString, classType);
    } catch (Exception e) {
        throw new Exception("Unable to convert to DTO :" + e.getMessage(), e);
    } 
    return obj;
}

I think you need a custom deserializer. Standard ObjectMapper will do all or nothing. Read more about creating a custom deserializer for Jackson ObjectMapper here:
