Methods of converting object beans and dbobject to each other when Java operations MongoDB (recommended) _java

The

looks like this:

Package com.iqbon.spider.util; 
Import Java.lang.reflect.Field; 
Import java.lang.reflect.InvocationTargetException; 
 
Import Java.util.Date; 
 
Import Org.apache.commons.beanutils.BeanUtils; 
Import Com.mongodb.BasicDBObject; 
 
Import Com.mongodb.DBObject; public class Beanutil {/** * Converts entity bean objects to DBObject * @param bean * @return * @throws illegalargumentexcept Ion * @throws Illegalaccessexception */public static <T> dbobject bean2dbobject (T Bean) throws Illegalargum 
  Entexception, Illegalaccessexception {if (bean = = null) {return null; 
  } dbobject dbobject = new Basicdbobject (); 
  Gets all the property fields in the corresponding class of the object field[] fields = Bean.getclass (). Getdeclaredfields (); 
   for (Field field:fields) {//Get property name String VarName = Field.getname (); 
   Modify access control permissions Boolean accessflag = Field.isaccessible (); 
   if (!accessflag) {field.setaccessible (true); 
   Object param = field.get (bean); if (param = = null) {continue; 
   else if (param instanceof Integer) {//the type int value = ((Integer) param) of the variable. intvalue (); 
   Dbobject.put (varName, value); 
    else if (param instanceof string) {String value = (string) param; 
   Dbobject.put (varName, value); 
    else if (param instanceof Double) {Double value = (double) param). Doublevalue (); 
   Dbobject.put (varName, value); 
    else if (param instanceof float) {Float value = ((Float) param). Floatvalue ();

}
