Map转成JavaBean

 

应用场景：使用Hibernate查询的时候查询结果经常会需要返回一个Map，这个时候就需要把Map转换成对应的Bean对象以适用于业务的需要。懒人就的事情就是写些工具类来实现这些操作。

 

 

package com.test;

import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;
import java.util.HashMap;
import java.util.Locale;
import java.util.Map;

public class ConvertUtil {
	public static void main(String[] args) {
		ConvertUtil convertUtil = new ConvertUtil();
		Map<String, String> map = new HashMap<String, String>();
		map.put("NAME", "name1");
		map.put("SEX", "sex1");

		Person person1=new Person();
		try {
			person1 = (Person) convertUtil.convert2Bean(map, person1);
			System.out.println(person1.getName());
			System.out.println(person1.getSex());
		} catch (Exception e) {
			e.printStackTrace();
		}
	}

	public static final String setMethodModify = "set";

	public Object convert2Bean(Map<String, String> map, Object obj) {
		Class class1 = obj.getClass();
		Method[] methods = class1.getMethods();
		for (Method method : methods) {
			String methodName = method.getName();
			if (methodName.startsWith(ConvertUtil.setMethodModify)) {
				String propertyName = methodName.substring(3).toUpperCase(
						Locale.getDefault());
				String value = map.get(propertyName);
				try {
					method.invoke(obj, value);
				} catch (IllegalArgumentException e) {
					e.printStackTrace();
				} catch (IllegalAccessException e) {
					e.printStackTrace();
				} catch (InvocationTargetException e) {
					e.printStackTrace();
				}
			}
		}
		return obj;
	}
}

class Person {
	private String name;
	private String sex;

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	public String getSex() {
		return sex;
	}

	public void setSex(String sex) {
		this.sex = sex;
	}

}
