利用Dozer实现vo-Entiy-Model中属性的复用

Posted 2022-12-03 陈晓婵

1.背景描述

        将entity中的属性,赋值给model,或者是vo.这样如果用之前的一个个的**entity.setId(**model.getId)这样的方法,将各个属性赋值会特别麻烦.所以封装了BeanMapperUtil这个类.一共两个方法,一个方法是map(返回entity),一个是mapList(返回List<entity>).

2.代码实现

package com.dmsdbj.itoo.examinationEvaluation.util;

import java.util.ArrayList;
import java.util.Collection;
import java.util.Iterator;
import java.util.List;
import org.dozer.DozerBeanMapper;

/**

public class BeanMapperUtil 
	private static DozerBeanMapper dozer = new DozerBeanMapper();

	public static <T> T map(Object sourceObject, Class<T> destObjectclazz) 
		return sourceObject == null ? null : dozer.map(sourceObject, destObjectclazz);
	

	public static <T, S> List<T> mapList(Collection<S> sourceList, Class<T> destObjectclazz) 
		if (sourceList == null) 
			return null;
		
		List<T> destinationList = new ArrayList<T>();
		for (Iterator<S> it = sourceList.iterator(); it.hasNext();) 
			destinationList.add(map(it.next(), destObjectclazz));
		
		return destinationList;
	

需要在pom文件中添加的jar包
