Java 将字符串传递到ApplicationAdvice中的静态图像引用

我有一个

ApplicationAdvice

类，它在每页上传递对配置文件图片的引用：

@ControllerAdvice
public class ApplicationAdvice {
...

@ModelAttribute("currentProfilePicture")
    public String currentProfilePicture(Principal principal, Model model) {

        if (principal != null) {
            String currentProfilePicture = "@{/images/default-profile-picture.png}";
            log.info(currentProfilePicture);
            model.addAttribute("currentProfilePicture", currentProfilePicture);
            return currentProfilePicture;
        } else {
            String currentProfilePicture = "@{/images/default-profile-picture.png}";
            log.info(currentProfilePicture);
            model.addAttribute("currentProfilePicture", currentProfilePicture);
            return currentProfilePicture;
        }
    }
}

HTML:

我没有正确地逃离静态引用吗

@{/images/default profile picture.png}

url字符串会很好地打印出来。。。我基本上只想将一个字符串传递到一个静态文件中的img标记。

它应该是这样的：

String currentProfilePicture=“/images/default profile picture.png”


如果不进行一些预处理，就无法传递整个thymeleaf字符串进行求值，但是上面的操作应该是您想要的

<img class="profilePicture hvr-pulse-grow" th:src="${currentProfilePicture}" />
