### 声明*路径参数*

使用 Enum 类（`ModelName`）创建使用类型注解的*路径参数*：

        return asListHtml();
    }

    @Execute
    @Secured({ ROLE, ROLE + VIEW })
    public HtmlResponse list(final OptionalThing<Integer> pageNumber, final SearchForm form) {
        pageNumber.ifPresent(num -> {
            webAuthPager.setCurrentPageNumber(pageNumber.get());
        }).orElse(() -> {
            webAuthPager.setCurrentPageNumber(0);
        });

//
// If the current file is sparse and r is an io.ReadSeeker,
// then readFrom uses Seek to skip past holes defined in Header.SparseHoles,
// assuming that skipped regions are all NULs.
// This always reads the last byte to ensure r is the right size.
//
// TODO(dsnet): Re-export this when adding sparse file support.
// See https://golang.org/issue/22735
