java - Spring Boot 2+ Thymeleaf 3.0.10 异常处理 - 无法返回 error.html

标签 java spring spring-mvc spring-boot thymeleaf

我正在使用 SpringBoot2 和 Thymeleaf 3.0.10 版本，我想通过使用 ErrorController 使用/error 路径来处理 thymeleaf 异常。我成功地将错误输入 Controller 。但它没有返回我的自定义错误 View 页面(/错误)。它返回我有错误的页面(/errorPageUrl)。

我的 Controller 类是

@Controller 
public class AppErrorController extends AbstractControllerImpl implements ErrorController {

private static final String PATH = "/error";

@Autowired
private ErrorAttributes errorAttributes;

@RequestMapping(value = PATH)
public ModelAndView error(HttpServletRequest request, HttpServletResponse response) {
    ModelAndView mav = new ModelAndView();
    ServletWebRequest webRequest = new ServletWebRequest(request);
    PageError pageError = new PageError(response.getStatus(), getErrorAttributes(webRequest, true), false);
    mav.addObject("pageError", pageError);
    mav.setViewName("common/error");
    log.error("Page Error: " + pageError.error + "\n" + pageError.trace);
    return mav;
}

@Override
public String getErrorPath() {
    return PATH;
}

private Map<String, Object> getErrorAttributes(ServletWebRequest request, boolean includeStackTrace) {
    return errorAttributes.getErrorAttributes(request, includeStackTrace);
}
}

这里我得到错误路径，然后重定向到“常见/错误”页面。但它正在重定向到另一个页面，我有错误片段“testing/testEntries”。

我查看了error.html。没关系，我在这里没有使用任何东西。我只是显示 PageError 类属性。

此错误 Controller 在 SpringBoot 1.5.7 和 Thymeleaf 2.x 上运行良好。 我在这里错过了什么吗？

更新5 此配置适用于语法错误，例如(缺少像这样的 anchor 的结束标记..)，当涉及到像 th:field="*{test.testingString}"这样的绑定(bind)结果时，它不起作用..我是否缺少为此配置的内容？

最佳答案 

nested exception is org.thymeleaf.exceptions.TemplateInputException: An error happened during template parsing (template: "class path resource [templates/common/error.html]

通过上述异常，您似乎在某处缺少结束标记。请检查您的 html 页面是否所有标记都正确关闭。
