java Method类试用

背景：在项目中有一堆javabean，要用在界面上画一堆tableview，要对这一堆tableview进行排序，因此要写一堆sorter类（假如为每个tableview都写一个的话），工作量比较大。
??????? 思考：其实这些sorter类都是差不多的，只是调用的javabean不同，方法名称不同，实现的原理，没有什么不同，那么该如何使用一个sorter类就可对所有的tableview进行排序呢？
??????? 思考结果：也许可以用Class类与Method类，也就是什么reflect机制。
??????? 困难：从来没用过reflect机制。

?????? 没有过，没关系。JDK5.0文档与google是我最好的老师。
?????? 下面就是我的成果了：
?????? 第一步，先建个javabean：
package?test;

public?class?Model?{

????private?String?id;
????private?String?name;
????private?String?description;
????
????public?Model()?{
????????id?=?"id";
????????name?=?"name";
????????description?=?"description";
????}

????public?String?getId()?{
????????return?id;
????}

????public?void?setId(String?id)?{
????????this.id?=?id;
????}

????public?String?getName()?{
????????return?name;
????}

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

????public?String?getDescription()?{
????????return?description;
????}

????public?void?setDescription(String?description)?{
????????this.description?=?description;
????}

}

??????? 第二步：
package?test;

import?java.lang.reflect.InvocationTargetException;
import?java.lang.reflect.Method;

public?class?TestMethodReflect?{

????public?static?final?String?ID?=?"Id";
????public?static?final?String?NAME?=?"Name";
????public?static?final?String?DESCRIPTION?=?"Description";

????//方法名集合
????public?static?final?String[]?ALL?=?{?ID,?NAME,?DESCRIPTION?};

????//这是测试数据
????public?static?final?String[]?MODELDATA?=?{?"1",?"Gavin",
????????????"this?is?model's?test?data"?};

????/**
?????*?@param?args
?????*/
????public?static?void?main(String[]?args)?{
????????try?{
????????????//获得Model类
????????????Class?model?=?Class.forName("test.Model");
????????????//获得Model类的实例
????????????Object?object?=?model.newInstance();
????????????for?(int?i?=?0;?i?<?ALL.length;?i++)?{
????????????????//获得Model类的set方法，参数为String类型
????????????????Method?setMethod?=?model.getMethod("set"?+?ALL[i],?String.class);
????????????????//调用set方法
????????????????setMethod.invoke(object,?MODELDATA[i]);

????????????????//获得Model类的get方法，无参数
????????????????Method?getMethod?=?model.getMethod("get"?+?ALL[i],?null);
????????????????//调用get方法，并输出数据
????????????????System.out.println(getMethod.invoke(object,?null));
????????????}
????????}?catch?(ClassNotFoundException?e)?{
????????????//?TODO?Auto-generated?catch?block
????????????e.printStackTrace();
????????}?catch?(SecurityException?e)?{
????????????//?TODO?Auto-generated?catch?block
????????????e.printStackTrace();
????????}?catch?(NoSuchMethodException?e)?{
????????????//?TODO?Auto-generated?catch?block
????????????e.printStackTrace();
????????}?catch?(IllegalArgumentException?e)?{
????????????//?TODO?Auto-generated?catch?block
????????????e.printStackTrace();
????????}?catch?(IllegalAccessException?e)?{
????????????//?TODO?Auto-generated?catch?block
????????????e.printStackTrace();
????????}?catch?(InvocationTargetException?e)?{
????????????//?TODO?Auto-generated?catch?block
????????????e.printStackTrace();
????????}?catch?(InstantiationException?e)?{
????????????//?TODO?Auto-generated?catch?block
????????????e.printStackTrace();
????????}

????}

}

??????? ok，大功告成！
??????? 成功后的思考：我只要在一个sorter类里添加一个classname的参数，添加一个methodName的参数（类型为String[]），用一个for循环就有可能用一个sorter类为每个tableview加入排序的功能。
