使用Java 语言可以方便的把任意对象转换成json格式的数据

import java.util.ArrayList;  
import java.util.List;  
  
import org.codehaus.jackson.map.ObjectMapper;  
  
public class SqlToJson {  
    public static void main(String[] args) {  
        List arrList = new ArrayList();  
        Person person = new Person("kang", 24);  
        arrList.add(person);  
        String str = null;  
        try {  
            str = gnerateJsonFromObject(arrList);  
        } catch (Exception e) {  
            e.printStackTrace();  
        }  
        System.out.println(str);  
    }  
  
    public static String gnerateJsonFromObject(Object object) throws Exception {  
        ObjectMapper mapper = new ObjectMapper();  
        return mapper.writeva lueAsString(object);  
    }  
}
