如何輸出動態圖片

Tapestry 5 中實現就是太簡單了。

在Java代碼中添加
@Inject
private ComponentResources resources;
public Link getImageUrl() {
        //image 這裡的image對應的後邊的onImage方法哦
        return resources.createEventLink("image", photo.getFilepath());
}
public StreamResponse onImage(final String path) {
        return new StreamResponse() {
            public String getContentType() {
                return "image/jpeg";
            }
            public InputStream getStream() throws IOException {
                return new FileInputStream(path);
            }
            public void prepareResponse(Response response) {
            }
        };
    }

在tml檔案中添加
