Converts the map object in the List collection into Listless than object greater than form instance code

The main implementation of this article is to convert map objects in the List collection to List < object > Form, the following is the complete code:

import java.util.ArrayList;
import java.util.HashMap;
import java.util.Iterator;
import java.util.List;
import java.util.Map;
import org.apache.commons.beanutils.ConvertUtils;
import org.apache.commons.beanutils.PropertyUtils;
public class EntityBean {
	/**
  *  This method implementation JDBCTemplate
  *  The returned Map Automatic collection of data 
  *  Encapsulated functionality 
  * List Collection store 1 A series of MAP
  *  Object, obj for 1 a javaBean
  * @param listMap A collection of 
  * @param objjavaBean object 
  * @return
  */
	public List parse(List list,Class obj){
		// Generating set 
		ArrayList ary = new ArrayList();
		// Iterate over all the data in the collection 
		for (int i = 0; i<list.size(); i++){
			try {
				//// Generate object real history   will MAP All parameters are encapsulated in the object 
				Object o = this.addProperty( (Map)list.get(i),obj.newInstance() );
				// Adds an object to a collection 
				ary.add(o);
			}
			catch (InstantiationException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
			catch (IllegalAccessException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
		}
		// Returns the encapsulated collection 
		return list;
	}
	/**Map The value in object is  name=aaa,value=bbb
   A method is called  
  addProperty(map,user);
  * Will automatically map Value assigned to user class 
  * This method combines Spring Framework of the jdbcTemplete Will not 
  * Often use  
  * @param map Stores a collection of names and values 
  * @param obj Object to encapsulate 
  * @return Encapsulated object 
  */
	public Object addProperty(Map map,Object obj){
		// Iterate over all the names 
		Iterator it = map.keySet().iterator();
		while(it.hasNext()){
			// Get the name 
			String name = it.next().toString();
			// Obtains the value 
			String value = map.get(name).toString();
			try{
				// Gets the class shape of the value 
				Class type = PropertyUtils.getPropertyType(obj, name);
				if(type!=null){
					// Set the parameters 
					PropertyUtils.setProperty(obj, name,ConvertUtils.convert(value, type));
				}
			}
			catch(Exception ex){
				ex.printStackTrace();
			}
		}
		return obj;
	}
}
// Method of use 
List stuGroupList2=new ArrayList();
EntityBean entbean=new EntityBean();
for (DynaBean stubean : stuGroupList) {
	　　　　if (stubean.get("GROUP_ID") != null&& stubean.get("GROUP_ID").equals(group_id)) {
		　　　　　　　　LinkedHashMap map=new LinkedHashMap();
		　　　　　　　　map.put("choose_id", stubean.get("CHOOSE_ID"));
		　　　　　　　　map.put("group_user_typecode", stubean.get("GROUP_USER_TYPECODE"));
		　　　　　　　　map.put("group_id", stubean.get("GROUP_ID"));
		　　　　　　　　map.put("realname", stubean.get("REALNAME"));
		　　　　　　　　stuGroupList2.add(map);
		　　　　
	}
}
stuGroupList2=entbean.parse(stuGroupList2, stuGroup.class);

conclusion

That's all about converting map objects in the List collection to List < object > The full content of the form instance code, I hope to help you.
