为Spring Boot REST应用程序处理404错误时出错

我在Spring引导异常处理中试图伸出援手。我已经创建了一个REST应用程序，并且该应用程序适用于所有有效的url。我想处理无效网址的例外情况。但如果我尝试打网址无效的申请，我得到以下异常： -为Spring Boot REST应用程序处理404错误时出错

作为新的春天开机我无法找出原因。任何指针或建议都会有帮助。

想试试本网站中提到的选项enter link description here，一旦我能够删除异常。

任何关于如何在Spring 4中处理404注释的指针都会非常有帮助。

试行下面的代码： -

@Configuration 
@EnableWebMvc 
@EnableSwagger 
public class WebConfig extends WebMvcConfigurerAdapter { 
....... 

    @Bean 
      public EmbeddedServletContainerCustomizer containerCustomizer() { 

       return new EmbeddedServletContainerCustomizer() { 
       @Override 
       public void customize(ConfigurableEmbeddedServletContainer container) { 

        ErrorPage error401Page = new ErrorPage(HttpStatus.UNAUTHORIZED, "/401.html"); 
        ErrorPage error404Page = new ErrorPage(HttpStatus.NOT_FOUND, "/401.html"); 
        ErrorPage error500Page = new ErrorPage(HttpStatus.INTERNAL_SERVER_ERROR, "/401.html"); 

        container.addErrorPages(error401Page, error404Page, error500Page); 
       } 
      }; 
     }

从pom.xml中添加的依赖性

<dependency> 
      <groupId>org.springframework.boot</groupId> 
      <artifactId>spring-boot-starter-actuator</artifactId> 
      <version>1.1.5.RELEASE</version>

应用离子适用于有效的URL映射。它使用弹簧引导来构建。 PFB应用注释类： -

@EnableJpaRepositories 
    @EnableAutoConfiguration 
    public class AppConfig { 


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



@Configuration 
@EnableWebMvc 
public class WebApplicationConfig extends WebMvcConfigurerAdapter { 

    @Override 
    public void configureMessageConverters(
      List<HttpMessageConverter<?>> converters) { 
     MappingJackson2HttpMessageConverter mappingJackson2HttpMessageConverter = new MappingJackson2HttpMessageConverter(); 

     converters.add(mappingJackson2HttpMessageConverter); 
     converters.add(new StringHttpMessageConverter()); 

     super.configureMessageConverters(converters); 
    } 

public class WebApplicationXML extends SpringBootServletInitializer { 
    @Override 
    protected SpringApplicationBuilder configure(
      SpringApplicationBuilder application) { 
     return application.sources(Application.class); 
    } 

}

得到它为我用一个简单的404也许是时候分享整个项目和一些步骤来重现后此链接？ – 2014-09-02 13:58:43

我有一些工作，但不完全。删除@EnableWebMvc后，我没有收到错误。我得到了默认的Whitemarker页面。 – Manu 2014-09-04 11:48:34

你需要打开一下。是否有堆栈跟踪？ – 2014-09-04 21:09:58

如果404发生，我已经添加了映射到重定向到自定义html页面。 PFB为此所做的更改：

从 WebConfig.java类中删除了Annotation @EnableWebMvc。这样做是为了消除错误“响应已经提交”，尝试任何无效的网址。

添加以下代码WebConfig.java类和亡魂的html页面：

@Bean 
public EmbeddedServletContainerCustomizer containerCustomizer() { 

    return new EmbeddedServletContainerCustomizer() { 
     @Override 
     public void customize(ConfigurableEmbeddedServletContainer container) { 

      ErrorPage error401Page = new ErrorPage(HttpStatus.UNAUTHORIZED, 
        "/401.html"); 
      ErrorPage error404Page = new ErrorPage(HttpStatus.NOT_FOUND, 
        "/404.html"); 
      ErrorPage error500Page = new ErrorPage(
        HttpStatus.INTERNAL_SERVER_ERROR, "/500.html"); 
      ErrorPage error505Page = new ErrorPage(
        HttpStatus.HTTP_VERSION_NOT_SUPPORTED, "/505.html"); 
      ErrorPage error506Page = new ErrorPage(
        HttpStatus.METHOD_NOT_ALLOWED, "/405.html"); 
      container.addErrorPages(error401Page, error404Page, 
        error500Page, error505Page, error506Page); 
     } 
    }; 
}

非常感谢您的建议答熟知。这非常有用。

我也跟着通过初步exeception

我无法按照链接中的步骤操作，因为当我尝试使用未知网址时，出现上述错误。 – Manu 2014-09-01 13:44:37

我已经在问题中给出了同样的链接作为我的参考。如果有关于例外的任何信息，请告诉我。 – Manu 2014-09-01 15:42:57

升级到春季启动1.1.5.RELEASE。

使用最新版本 – Manu 2014-09-01 19:42:32

感谢Dave Syer的建议。使用最新版本的spring boot.I已经从pom.xml添加了spring引导依赖关系。但是没有运气......相同错误 – Manu 2014-09-02 05:50:14

堆栈跟踪仍然显示1.1.4。如果你还没有更新，你还能更新吗？ – 2014-09-02 06:18:55
