org.apache.commons.beanutils.BeanUtils用法

BeanUtils提供对 Java反射和自省API的包装。其主要目的是利用反射机制对JavaBean的属性进行处理。我们知道，一个JavaBean通常包含了大量的属性，很多情况下，对JavaBean的处理导致大量get/set代码堆积，增加了代码长度和阅读代码的难度。实例:
CorporationInfo corp = new CorporationInfo();
            corp.setId(spForm.getCorpCode());
            boolean bload = true;
            try {
                corp = (CorporationInfo) corp.openById();
            } catch (Exception e) {
                bload = false;
            }
            if (bload) {
                        Map corpMap = BeanUtils.describe(corp);
                Map formMap = BeanUtils.describe(form);
                System.out.println("载入信息." + corpMap + "\r\n" + formMap);
                for (Iterator it = corpMap.keySet().iterator(); it.hasNext();) {
                    String name = (String) it.next();
                    System.out.println("set "+name+"   "+corpMap.get(name));
                    if (Function.normalizeString(name).toLowerCase().equals("id") ||
                            Function.normalizeString(name).equals("") ||
                            Function.normalizeString(name).equals("status") ||
                            Function.normalizeString(name).equals("action"))
                        continue;
                    if (formMap.containsKey(name) && null != corpMap.get(name)) {
                        try {
                            BeanUtils.copyProperty(form, name, corpMap.get(name));
                            System.out.println("set "+name+"   "+corpMap.get(name));
                        } catch (InvocationTargetException e) {
                            System.out.println(e.getMessage());
                        } catch (Exception ie) {
                            System.out.println(ie.getMessage());
                        }
                    }
                }
                if (formMap.containsKey("appliedcorp")) {
                    BeanUtils.copyProperty(form, "appliedcorp", corpMap.get("corpname"));
                }
            }
        }
