Error while redirecting to custom error page in Spring boot application

javaspringspring-boot

提问by ashishjmeshram

I am using spring boot and I have created following custom Error Controller to handle errors:

我正在使用 spring boot 并且我创建了以下自定义错误控制器来处理错误：

@Controller
public class AppErrorController implements ErrorController {

    private static final String PATH = "/error";

    @RequestMapping(value = "/pageNotFound", method = { RequestMethod.GET, RequestMethod.POST })
    public String pageNotFound() {
        return "pageNotFound";
    }

    @RequestMapping(value = "/accessDenied", method = { RequestMethod.GET, RequestMethod.POST })
    public String accessDenied() {
        return "accessDenied";
    }

    @RequestMapping(value = PATH)
    public String error() {
        return "error";
    }

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

When I get an error in the application, it should redirect to custom error pages. Instead I get the following error in the logs and even the error page don't show up:

当我在应用程序中遇到错误时，它应该重定向到自定义错误页面。相反，我在日志中收到以下错误，甚至错误页面也不显示：

Traditional Deployment

传统部署

If you're not using an embedded servlet container, just disable the white label by adding this to your application.properties:

如果您没有使用嵌入式 servlet 容器，只需将以下内容添加到您的application.properties:

<dependency>
    <groupId>org.apache.tomcat.embed</groupId>
    <artifactId>tomcat-embed-jasper</artifactId>
</dependency>

Embedded Tomcat Scenario

嵌入式Tomcat场景

Add the tomcat-embed-jasperas your dependency:

添加tomcat-embed-jasper作为您的依赖项：

@Controller("error")
public class AppErrorController implements ErrorController { ... }

And name your controller as error:

并将您的控制器命名为error：

server.error.whitelabel.enabled = false

Or you can disable the white label, instead of renaming the bean:

或者您可以禁用白色标签，而不是重命名 bean：

@Configuration
@ConditionalOnProperty(prefix = "server.error.whitelabel", name = "enabled", matchIfMissing = true)
@Conditional(ErrorTemplateMissingCondition.class)
protected static class WhitelabelErrorViewConfiguration {

    private final SpelView defaultErrorView = new SpelView(
            "<html><body><h1>Whitelabel Error Page</h1>"
                    + "<p>This application has no explicit mapping for /error, so you are seeing this as a fallback.</p>"
                    + "<div id='created'>${timestamp}</div>"
                    + "<div>There was an unexpected error (type=${error}, status=${status}).</div>"
                    + "<div>${message}</div></body></html>");

    @Bean(name = "error")
    @ConditionalOnMissingBean(name = "error")
    public View defaultErrorView() {
        return this.defaultErrorView;
    }

    // rest of the configuration
}

Why the Name Matters?

为什么名称很重要？

After a little digging in ErrorMvcAutoConfigurationauto configuration, i've encountered with following piece of configuration:

在对ErrorMvcAutoConfiguration自动配置进行了一些挖掘之后，我遇到了以下配置：

@ConditionalOnMissingBean(name = "error")
public View defaultErrorView() { ... }

That timestamp issue is related to defaultErrorViewof type SpelView. So if you register another bean named error:

该时间戳问题与defaultErrorView类型有关SpelView。因此，如果您注册另一个名为 的 bean error：

@ConditionalOnProperty(prefix = "server.error.whitelabel", name = "enabled", matchIfMissing = true)

Or disable white label:

或禁用白标：

public boolean isTemplateAvailable(String view, Environment environment,
        ClassLoader classLoader, ResourceLoader resourceLoader) {
    if (ClassUtils.isPresent("org.apache.jasper.compiler.JspConfig", classLoader)) {
        String prefix = getProperty(environment, "spring.mvc.view.prefix",
                "spring.view.prefix", WebMvcAutoConfiguration.DEFAULT_PREFIX);
        String suffix = getProperty(environment, "spring.mvc.view.suffix",
                "spring.view.suffix", WebMvcAutoConfiguration.DEFAULT_SUFFIX);
        return resourceLoader.getResource(prefix + view + suffix).exists();
    }
    return false;
}

This view won't be registered and you will avoid that weird exception.

这个视图不会被注册，你会避免那个奇怪的异常。

What About Jasper Dependency?

Jasper 依赖呢？

There is a JspTemplateAvailabilityProviderthat provides availability information for JSP view templates. This class has a isTemplateAvailablemethod that looks like:

有一个JspTemplateAvailabilityProvider为 JSP 视图模板提供可用性信息。这个类有一个isTemplateAvailable看起来像这样的方法：

public class MyApplication {

    public static void main(String[] args) {
        SpringApplication.run(UserDocumentLibraryClientApplication.class, args);
    }

   ...
    @Bean
    public EmbeddedServletContainerCustomizer exceptionHandling() {
        return container -> container.addErrorPages(new ErrorPage("/exception"));
    }
}

So if the org.apache.jasper.compiler.JspConfigwas not present in the classpath, it won't render the jsp view, so we added the required dependency for that, which is tomcat-embed-jasper.

因此，如果org.apache.jasper.compiler.JspConfig类路径中不存在 ，则不会呈现 jsp 视图，因此我们为此添加了所需的依赖项，即tomcat-embed-jasper.

Maybe there is a better and less hacky way for this problem but this is the solution i came up with and it is what it is!

对于这个问题，也许有更好、更简单的方法，但这是我想出的解决方案，它就是这样！

You had many way for managing the error with spring boot. If you read the documentation the official doc say hovewer the best that I used in my projects was of develop a controller for manage the exception and then configure the error page of my tomcat, if you use tomcat but the way was the same for other container. I report a configuration sample:

你有很多方法来管理 Spring Boot 的错误。如果您阅读文档，官方文档说我在我的项目中使用的最好的方法是开发一个控制器来管理异常，然后配置我的 tomcat 的错误页面，如果您使用 tomcat，但其他容器的方式相同. 我报告一个配置示例：

container configuration:

容器配置：

@Controller
public class ExceptionController {

    @Autowired
    private MessageSource messageSource;

    public void setMessageSource(MessageSource messageSource) {
        this.messageSource = messageSource;
    }

    @RequestMapping("/exception")
    public String exception(Model model,Exception ex,Locale locale,HttpServletRequest httpRequest,HttpServletResponse httpResponse){

        ex.printStackTrace();

        model.addAttribute("templatePath", "exception/exception");
        model.addAttribute("template", "content");
        try{
            model.addAttribute("exceptionMessage",messageSource.getMessage(String.format("exception.body.%s",httpResponse.getStatus()),new Object[]{},locale));
        } catch (NoSuchMessageException e){
            model.addAttribute("exceptionMessage",messageSource.getMessage("exception.body",new Object[]{},locale));
        }
        return "index";
    }
}

controller:

控制器：

...
server.error.whitelabel.enabled=false
...

application.properties

应用程序属性

##代码##

the index view may be the your thymeleaf template and benefit of the same template of your application.

索引视图可能是您的 thymeleaf 模板和应用程序相同模板的好处。

Of course this is just an example but even in the documentation you can read that if you want a fine grain configuration option this a good options.

当然，这只是一个例子，但即使在文档中你也可以阅读，如果你想要一个细粒度的配置选项，这是一个很好的选择。

I hope that this can help you
