    protected T initEntity(EmsEsBizDTO emsEsBizDTO) throws Exception {
        // 本类的泛型参数
        ParameterizedType ptype = (ParameterizedType) this.getClass().getGenericSuperclass();
        // 下标1表示第二个参数: T的Class
        Class<T> clazz = (Class<T>) ptype.getActualTypeArguments()[1];
        return this.initEntity(emsEsBizDTO, clazz);
