用JAVA Bean 反射得到set,get方法
/** * java反射bean的get方法 * * @param objectClass * @param fieldName * @return */ @SuppressWarnings("unchecked") public static Method getGetMethod(Class objectClass, String fieldName) { StringBuffer sb = new StringBuffer(); sb.append("get"); sb.append(fieldName.substring(0, 1).toUpperCase()); sb.append(fieldName.substring(1)); try { return objectClass.getMethod(sb.toString()); } catch (Exception e) { } return null; } /** * java反射bean的set方法 * * @param objectClass * @param fieldName * @return */ @SuppressWarnings("unchecked") public static Method getSetMethod(Class objectClass, String fieldName) { try { Class[] parameterTypes = new Class[1]; Field field = objectClass.getDeclaredField(fieldName); parameterTypes[0] = field.getType(); StringBuffer sb = new StringBuffer(); sb.append("set"); sb.append(fieldName.substring(0, 1).toUpperCase()); sb.append(fieldName.substring(1)); Method method = objectClass.getMethod(sb.toString(), parameterTypes); return method; } catch (Exception e) { e.printStackTrace(); } return null; } /** * 执行set方法 * * @param o执行对象 * @param fieldName属性 * @param value值 */ public static void invokeSet(Object o, String fieldName, Object value) { Method method = getSetMethod(o.getClass(), fieldName); try { method.invoke(o, new Object[] { value }); } catch (Exception e) { e.printStackTrace(); } } /** * 执行get方法 * * @param o执行对象 * @param fieldName属性 */ public static Object invokeGet(Object o, String fieldName) { Method method = getGetMethod(o.getClass(), fieldName); try { return method.invoke(o, new Object[0]); } catch (Exception e) { e.printStackTrace(); } return null; }
