javascript - ResponseEntity，如何在HTML中获取正文

我想在浏览器中显示由Controller返回的ResponseEntity的主体(使用Spring):
return new ResponseEntity<>(l.getReachableDate(), HttpStatus.NOT_FOUND);l.getReachableDate()返回日期类型，我想以如下方式显示它:

<header>
    <h1><span>Url is not reachable from</span> <!-- body --> </h1>
</header>

如何显示它？

最佳答案

我仍然不明白您为什么要这样做，但是这样就可以了

@RequestMapping(value="/controller", method=GET)
public ResponseEntity<String> foo() {
    String content =
           "<header>"
         + "<h1><span>Url is not reachable from</span>" +  l.getReachableDate() + "</h1>"
         + "</header>";
    HttpHeaders responseHeaders = new HttpHeaders();
    responseHeaders.setContentType(MediaType.TEXT_HTML);

    return new ResponseEntity<String>(content, responseHeaders, HttpStatus.NOT_FOUND);
}

经过一番评论...

与其将用户重定向到未找到资源的页面，还不如拥有一个ResourceNotFoundRuntimeException(扩展RuntimeException)并注册一个MVC异常处理程序(这是prem kumar所建议的，但是没有定制的异常html文本):

public class ResourceNotFoundRuntimeException extends RuntimeException{
...
}

处理程序:

@ControllerAdvice
public class ExceptionHandlerController {

    @ExceptionHandler(ResourceNotFoundRuntimeException .class)
    public ResponseEntity<String> resourceNotFoundRuntimeExceptionHandling(){
        String content =
               "<header>"
             + "<h1><span>Url is not reachable from</span>" +  l.getReachableDate() + "</h1>"
             + "</header>";
        HttpHeaders responseHeaders = new HttpHeaders();
        responseHeaders.setContentType(MediaType.TEXT_HTML);

        return new ResponseEntity<String>(content, responseHeaders, HttpStatus.NOT_FOUND);
    }
}
