java通过反射批量生成set设置值

对于大批量属性的类，里面有有很多属性，这个时候一个个写还是很痛苦的，通过java反射来获取这些类里面的方法，从而得到自己想要的set属性的字符串再好不过了。

下面是一个JDOM设置值的，直接反射生成即可

project.setSeatPicUrl(node.getChildText("seatPicUrl"));
project.setId(node.getChildText("id"));
project.setCategoryID(node.getChildText("categoryID"));
project.setSonCategoryID(node.getChildText("sonCategoryID"));
project.setSiteID(node.getChildText("siteID"));
project.setSiteName(node.getChildText("siteName"));
project.setSubHead(node.getChildText("subHead"));
project.setIsETicket(node.getChildText("isETicket"));
project.setMinPrice(node.getChildText("minPrice"));
project.setMaxPrice(node.getChildText("maxPrice"));
project.setPriceStr(node.getChildText("priceStr"));
project.setSellEndTime(node.getChildText("sellEndTime"));
project.setShowTime(node.getChildText("showTime"));
project.setCanSell(node.getChildText("canSell"));
project.setIsTest(node.getChildText("isTest"));
project.setVenueName(node.getChildText("venueName"));
project.setVenueID(node.getChildText("venueID"));
project.setIsXuanZuo(node.getChildText("isXuanZuo"));
project.setUpdateTime(node.getChildText("updateTime"));
project.setPerformIdList(node.getChildText("performIdList"));
project.setName(node.getChildText("name"));
project.setDescription(node.getChildText("description"));
project.setStatus(node.getChildText("status"));
