输出网页源码java

        try{
            Configuration configuration = freeMarkerConfig.getConfiguration();
            Template template = configuration.getTemplate("item.ftl");
            Map dataModel = new HashMap<>();
            //加载商品表数据
            TbGoods goods = goodsMapper.selectByPrimaryKey(goodsId);
            dataModel.put("goods", goods);

            //加载商品扩展表数据
            TbGoodsDesc goodsDesc = goodsDescMapper.selectByPrimaryKey(goodsId);
            dataModel.put("goodsDesc", goodsDesc);
            Writer out = new FileWriter(pagedir+goodsId + ".html");

            template.process(dataModel, out);

            out.close();
            return true;

        }catch (Exception e){
            e.printStackTrace();
            return false;
        }
    }

}

更改输出，按照UTF-8输出web

            configuration.setDefaultEncoding("UTF-8");
            Template template = configuration.getTemplate("item.ftl");
            template.setEncoding("UTF-8");
            Map dataModel = new HashMap<>();
            //加载商品表数据
            TbGoods goods = goodsMapper.selectByPrimaryKey(goodsId);
            dataModel.put("goods", goods);

            //加载商品扩展表数据
            TbGoodsDesc goodsDesc = goodsDescMapper.selectByPrimaryKey(goodsId);
            dataModel.put("goodsDesc", goodsDesc);
            //Writer out = new FileWriter(pagedir+goodsId + ".html")
            Writer out = new PrintWriter(pagedir+goodsId + ".html", "UTF-8");

            template.process(dataModel, out);

            out.close();
            return true;

        }catch (Exception e){
            e.printStackTrace();
            return false;
        }
    }

}

输出正常啦！
