在Spring启动应用程序中重定向到自定义错误页面时出错

时间：2016-03-09 04:17:00

标签： java spring spring-boot

我使用的是spring boot，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;
    }
}

当我在应用程序中出现错误时，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，甚至错误页面也没有显示：

如果您未使用嵌入式servlet容器，只需将此标签添加到application.properties：

即可停用此标签。 
server.error.whitelabel.enabled = false

嵌入式Tomcat方案

添加tomcat-embed-jasper作为您的依赖项：

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

并将控制器命名为error：

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

或者您可以禁用白标，而不是重命名bean：

server.error.whitelabel.enabled = false

为什么名称很重要？

在ErrorMvcAutoConfiguration自动配置中进行了一些挖掘后，我遇到了以下配置：

@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
}

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

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

或禁用白标：

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

此视图无法注册，您将避免这种奇怪的异常。

Jasper Dependency怎么样？

有JspTemplateAvailabilityProvider提供JSP视图模板的可用性信息。这个类有一个isTemplateAvailable方法，如下所示：

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;
}

因此，如果类路径中不存在org.apache.jasper.compiler.JspConfig，则它不会呈现jsp视图，因此我们添加了所需的依赖关系，即tomcat-embed-jasper。

对于这个问题，可能有更好的，更少的黑客方式，但这是我提出的解决方案，它就是它！

答案 1 :(得分：1)

使用spring boot管理错误有很多方法。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，如果你使用tomcat但是对于其他容器的方式是相同的。我报告了配置示例：

容器配置：

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"));
    }
}

控制器：

@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";
    }
}

application.properties 

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

索引视图可能是您的百万美元模板以及您应用程序的同一模板的好处。

当然这仅仅是一个例子，但即使在文档中你也可以阅读，如果你想要一个精细的粒度配置选项，这是一个很好的选择。

我希望这可以帮到你
