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<Person> arrList = new ArrayList<Person>();
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.writeValueAsString(object);
}
}
