Java对象与Map的转换

 首先是将map和要被赋值的Bean传进来

public static void setValue(Map map,Object thisObj) { Set set = map.keySet(); Iterator iterator = set.iterator(); while (iterator.hasNext()) { Object obj = iterator.next(); Object val = map.get(obj); setMethod(obj, val, thisObj); } }  

 

调用设值方法setMethod方法（暂时只支持传入String类型字段的处理）

public static void setMethod(Object method, Object value ,Object thisObj) { Class c; try { c = Class.forName(thisObj.getClass().getName()); String met = (String) method; met = met.trim(); if (!met.substring(0, 1).equals(met.substring(0, 1).toUpperCase())) { met = met.substring(0, 1).toUpperCase() + met.substring(1); } if (!String.valueOf(method).startsWith("set")) { met = "set" + met; } Class types[] = new Class[1]; types[0] = Class.forName("java.lang.String"); Method m = c.getMethod(met, types); m.invoke(thisObj, value); } catch (Exception e) { // TODO: handle exception e.printStackTrace(); } }

 

 

以上是直接把map数据传进Bean

 

下面是把Bean转换成map对象输出

public static Map getValue(Object thisObj) { Map map = new HashMap(); Class c; try { c = Class.forName(thisObj.getClass().getName()); Method[] m = c.getMethods(); for (int i = 0; i < m.length; i++) { String method = m[i].getName(); if (method.startsWith("get")) { try{ Object value = m[i].invoke(thisObj); if (value != null) { String key=method.substring(3); key=key.substring(0,1).toUpperCase()+key.substring(1); map.put(method, value); } }catch (Exception e) { // TODO: handle exception System.out.println("error:"+method); } } } } catch (Exception e) { // TODO: handle exception e.printStackTrace(); } return map; }

 

直接返回map，可以转换成json对象返回页面，便于Grid读取。
