输出网页源码

package com.pinyougou.page.service.impl;

import java.io.Writer;
import java.util.HashMap;
import java.util.Map;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.web.servlet.view.freemarker.FreeMarkerConfig;

import com.alibaba.dubbo.config.annotation.Service;

@Service
public class ItemPageServiceImpl implements ItemPageService {

    @Value("${pagedir}")
    private String pagedir;

    @Autowired
    private FreeMarkerConfig freeMarkerConfig;

    @Autowired
    private TbGoodsMapper goodsMapper;

    @Autowired
    private TbGoodsDescMapper goodsDescMapper;

    @Override
    public boolean genItemHtml(Long goodsId) {

        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

package com.pinyougou.page.service.impl;

import java.io.FileWriter;
import java.io.PrintWriter;
import java.io.Writer;
import java.util.HashMap;
import java.util.Map;

import org.springframework.beans.factory.annotation.Autowired;

import com.pinyougou.mapper.TbGoodsMapper;
import com.pinyougou.page.service.ItemPageService;
import com.pinyougou.pojo.TbGoods;
import com.pinyougou.pojo.TbGoodsDesc;

import freemarker.template.Configuration;
import freemarker.template.Template;

/**

@Service
public class ItemPageServiceImpl implements ItemPageService {

    @Value("${pagedir}")
    private String pagedir;

    @Autowired
    private FreeMarkerConfig freeMarkerConfig;

    @Autowired
    private TbGoodsMapper goodsMapper;

    @Autowired
    private TbGoodsDescMapper goodsDescMapper;

    @Override
    public boolean genItemHtml(Long goodsId) {

        try{
            Configuration configuration = freeMarkerConfig.getConfiguration();
            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！
