無法使用網址檢索上傳的文件

Question

我已成功將文件上傳到服務器，並且使用設置了路徑

String rootPath ="/home/me/Documents/tfmImages/";
File dir = new File(rootPath + File.separator + profile.getUser().getUserId());

我可以在目錄中看到文件，但是當我嘗試使用url（localhost：8080 / TFM / uploads / b26fc1011c164fa384fa05d845e9bd7a.png）訪問flie時，它顯示的是404。

這是資源處理程序方法

@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
    registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
    registry.addResourceHandler("/uploads/**").addResourceLocations("file:///home/me/Documents/tfmImages/");
}

我在兩個函數中使用相同的路徑。

這是我發送請求時的控制台輸出

它顯示了請求的匹配模式

Matching patterns for request [/uploads/b26fc1011c164fa384fa05d845e9bd7a.png] are [/uploads/**]

仍然無法使用url訪問圖像。 代碼有什么問題？

Answer 1

 String rootPath ="/home/me/Documents/tfmImages/";
   File dir = new File(rootPath + File.separator + profile.getUser().getUserId() 
   +"_user.png");

您必須在png，jpg，....根之后添加文件擴展名。
