2. 创建查询并分页

分页实例

@Test
    public void testPageHelper()
        //创建一个spring容器
        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("classpath:spring/applicationContext-*.xml");
        //从ApplicetionContext中获取Maper对象
        TbItemMapper maper = applicationContext.getBean(TbItemMapper.class);
        //执行查询并分页
        TbItemExample tbItemExample = new TbItemExample();
        //分页处理
        PageHelper.startPage(1, 10);
        List list = maper.selectByExample(tbItemExample);
        for (TbItem tbItem : list) {
            System.out.println(tbItem.getTitle());
        }
        //取分页信息
        PageInfo pageInfo = new PageInfo<>(list);
        long total = pageInfo.getTotal();
        System.out.println("共有商品: "+total);
    }

//1. 初始化spring容器
ApplicationContext applicationContext = new ClassPathXmlApplicationContext("classpath:spring/applicationContext-*.xml");        

/**
     * 一个handler代表一个请求路径
     */
    @RequestMapping("/{page}")
    public String showPage(@PathVariable String page){
        return page;
    }
