每日总结

昨天考完六级，今天写了软件构造的作业，

    public List<Tran> selecttres(String name) {
        String sql = "select * from translate where user = ?";
        List<Tran> resultList = dao.find(sql, name);
        // 直接返回这个List
        return resultList;
    }
    public List<Picture> selecttres2(String name) {
        String sql = "select * from picture where user = ?";
        List<Picture> resultList = dao2.find(sql, name);
        // 直接返回这个List
        return resultList;
    }

controller类：

public void resrcharts2() {
        String username = getPara("username");
        String sss="";
        //setAttr("res", adminService.selecttres(username));
        List<Picture> jsonData = adminService.selecttres2(username);
        System.out.println(jsonData);
        ObjectMapper objectMapper = new ObjectMapper();
        try {
            sss = objectMapper.writeValueAsString(jsonData);
            System.out.println(sss);
        } catch (JsonProcessingException e) {
            // 处理异常，例如记录日志或返回错误信息
            e.printStackTrace();
        }
        setAttr("res", sss);
        setAttr("username", username);
        render("res2.html");
    }
    public void resrcharts1() {
        String username = getPara("username");
        String sss="";
        //setAttr("res", adminService.selecttres(username));
        List<Tran> jsonData = adminService.selecttres(username);
        System.out.println(jsonData);
        ObjectMapper objectMapper = new ObjectMapper();
        try {
            sss = objectMapper.writeValueAsString(jsonData);
            System.out.println(sss);
        } catch (JsonProcessingException e) {
            // 处理异常，例如记录日志或返回错误信息
            e.printStackTrace();
        }
        setAttr("res", sss);
        setAttr("username", username);
        render("res.html");
    }
