话不多说,代码如下

package com.study;

import java.lang.reflect.Field;
import java.util.HashMap;
import java.util.Map; /**
* PackageName com.study
* Description please write description.
* User: yh
* Time: 2016/11/29 16:57
*/
public class mapUtil
{
/**
* javaBean 转 Map
* @param object 需要转换的javabean
* @return 转换结果map
* @throws Exception
*/
public static Map<String, Object> beanToMap(Object object) throws Exception
{
Map<String, Object> map = new HashMap<String, Object>(); Class cls = object.getClass();
Field[] fields = cls.getDeclaredFields();
for (Field field : fields) {
field.setAccessible(true);
map.put(field.getName(), field.get(object));
}
return map;
} /**
*
* @param map 需要转换的map
* @param cls 目标javaBean的类对象
* @return 目标类object
* @throws Exception
*/
public static Object mapToBean(Map<String, Object> map, Class cls) throws Exception
{
Object object = cls.newInstance();
for (String key : map.keySet()){
Field temFiels = cls.getDeclaredField(key);
temFiels.setAccessible(true);
temFiels.set(object, map.get(key));
}
return object;
}
}
