方式二:

 /**
     * @author huangjunyan
     * 函數將oldObject的值復制到newObject當中，用於批量復制
     * */
    public static void copyProperties(Object oldObject,Object newObject) throws Exception{
    //獲取oldObject的get方法域，遍歷方法域對比是否在newobject中存在set方法，
    //若存在則執行newObject對應的set方法
    if(oldObject==null||newObject==null)return;
    Method[]oldObjectMethods = oldObject.getClass().getMethods();
    Method[]newObjectMethods = newObject.getClass().getMethods();
    Map<String,Method>setMethodMap = new HashMap<String,Method>();
    //獲取所有set方法
    for(int j=0;j<newObjectMethods.length;j++){
        Method newObjectMethod = newObjectMethods[j];
        if(newObjectMethod.getName().startsWith("set")){
            setMethodMap.put(newObjectMethod.getName(), newObjectMethod);
            };
    }
    for(int i=0;i<oldObjectMethods.length;i++){
        Method oldObjectMethod = oldObjectMethods[i];
        if(oldObjectMethod.getName().startsWith("get")){
        String setName = oldObjectMethod.getName().replace("get", "set");
        if(setMethodMap.containsKey(setName)){
            Method newObjectMethod =setMethodMap.get(setName);
            //執行get，獲取需要設置的值
            Object object=oldObjectMethod.invoke(oldObject, new Object[0]);
            Object[]objectArray;
            if(object==null){
            objectArray = new Object[1];
            objectArray[0] = null;
            }else{
            objectArray = new Object[1];
            
            objectArray[0] =convertType(newObjectMethod,object);
            }
            newObjectMethod.invoke(newObject, objectArray);
        }
        }
    }
    }

根據屬性拿到get和set方法
