BeanUtil解析HttpServletRequest到Bean的测试

来源：互联网发布：av淘宝最新发布网站编辑：程序博客网时间：2024/05/16 14:36

这个东西在许多框架上已经内置实现了，只不过我还是对这个有兴趣，所以有重新测试了一下。

首发地址： http://www.laozizhu.com/view.jsp?articleId=103

我增强了默认的解析类，加上了日期的自定义解析，
1 先看解析类
package com.laozizhu.util;

import java.lang.reflect.InvocationTargetException;
import java.util.Map;
import javax.servlet.http.HttpServletRequest;
import org.apache.commons.beanutils.BeanUtils;
import org.apache.commons.beanutils.ConvertUtils;
import org.apache.commons.beanutils.converters.DateConverter;

/**
* 将HttpServletRequest解析并注入到Bean里面的辅助类。
*
* @author 老紫竹研究室(laozizhu.com)
*/
public class RequestToBean {
  static {
    DateConverter d = new DateConverter();
    String[] datePattern = { "yyyy-mm-dd", "yyyy/mm/dd", "yyyy.mm.dd" };
    d.setPatterns(datePattern);
    ConvertUtils.register(d, java.util.Date.class);
  }

  public static void populate(HttpServletRequest request, Object obj) {
    Map map = request.getParameterMap();
    try {
      BeanUtils.populate(obj, map);
    } catch (IllegalAccessException e) {
      e.printStackTrace();
    } catch (InvocationTargetException e) {
      e.printStackTrace();
    }
  }
}

2 测试用的基础类
package com.laozizhu.util.test;

import java.util.Date;

/**
* 基础数据类，包括常见的数据类型。
*
* @author 老紫竹研究室(laozizhu.com)
*/
public class Base {
  private long id;

  private String name;

  private float weight;

  private double height;

  private Date birthday;

  // 喜爱的数字
  private int[] numberFavorite;

  private boolean married;

  public boolean isMarried() {
    return married;
  }

  public void setMarried(boolean married) {
    this.married = married;
  }

  public long getId() {
    return id;
  }

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

  public String getName() {
    return name;
  }

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

  public Date getBirthday() {
    return birthday;
  }

  public void setBirthday(Date birthday) {
    this.birthday = birthday;
  }

  public float getWeight() {
    return weight;
  }

  public void setWeight(float weight) {
    this.weight = weight;
  }

  public double getHeight() {
    return height;
  }

  public void setHeight(double height) {
    this.height = height;
  }

  public int[] getNumberFavorite() {
    return numberFavorite;
  }

  public void setNumberFavorite(int[] numberFavorite) {
    this.numberFavorite = numberFavorite;
  }
}

3 测试用的JSP代码
<%@page c%>
<%@page import="com.laozizhu.util.*,com.laozizhu.util.test.*"%>
<%
  String title = "老紫竹研究室类库演示程序-基础测试：整数、浮点数、字符串、日期、多选数字、布尔";
%>
<html>
<head>
<title><%=title%></title>
</head>
<body>
<%
  request.setCharacterEncoding("UTF-8");
  Base b = new Base();
  RequestToBean.populate(request, b);
%>
<%=title%>
<br />
编号:<%=b.getId()%><br />
名字:<%=b.getName()%><br />
身高:<%=b.getHeight()%><br />
体重:<%=b.getWeight()%><br />
生日:<%=b.getBirthday()%><br />
婚否:<%=b.isMarried()%><br />
数字:<%
  if (b.getNumberFavorite() != null)
    for (int num : b.getNumberFavorite()) {
      out.print(num + ",");
    }
%>
<form method="post"><br />
编号:<input type="text" name="id" value="1" /><br />
名字:<input type="text" name="name" value="老紫竹" /><br />
身高:<input type="text" name="height" value="173.5" /><br />
体重:<input type="text" name="weight" value="90.3" /><br />
生日:<input type="text" name="birthday" value="2009-01-23" /><br />
婚否:<input type="radio" name="married" value="1" checked />已婚，<input type="radio" name="married" value="0" />未婚<br />
数字:<br />
<%
  for (int i = 0; i <= 9; i++) {
%> <input type="checkbox" name="numberFavorite" value="<%=i %>" <%=i%3==0?" checked":"" %> /><%=i%><br />
<%
  }
%> <input type="submit" value="提交测试" /><br />
</form>
</body>
</html>
