BeanUtils使用案例

//上面得到是一个封装为Map的集合
Map<String, String[]> parameterMap = request.getParameterMap();
//创建一个javaBean
        User user = new User();
//把集合封装为javaBean类型
        try {
            BeanUtils.populate(user, parameterMap);
        } catch (Exception e) {
            e.printStackTrace();
        }

userDao.insert(user);

@Override
    public void insert(User user) {

        String sql = "INSERT INTO tab_user(username, password, name, birthday, sex, telephone, email, status, code) values(?, ?, ?, ?, ?, ?, ?, ?, ?)";
        jdbcTemplate.update(sql, user.getUsername(), user.getPassword(), user.getName(), user.getBirthday(), user.getSex(), user.getTelephone(),
                user.getEmail(), user.getStatus(), user.getCode());
