request封装到Bean对象
public static <T> T request2Bean(HttpServletRequest httpServletRequest, Class<T> aClass) {
try {
//对于日期而言,是需要日期转换器的
ConvertUtils.register(new DateLocaleConverter(), Date.class);
//获取Bean的对象
T bean = aClass.newInstance();
httpServletRequest.setCharacterEncoding("UTF-8");
//获取表单中所有的名字
Enumeration enumeration = httpServletRequest.getParameterNames();
//遍历表单提交过来的名字
while (enumeration.hasMoreElements()) {
//每个名字
String name = (String) enumeration.nextElement();
//获取得到值
String value = httpServletRequest.getParameter(name);
//如果用户提交的数据不为空,那么将数据封装到Bean中
if (!value.equals("") && value != null) {
BeanUtils.setProperty(bean, name, value);
}
}
return bean;
} catch (Exception e) {
e.printStackTrace();
throw new RuntimeException("封装数据到Bean中,失败了!");
}
}
UUID工具方法

return UUID.randomUUID().toString();
}
