爲Spring Boot REST應用程序處理404錯誤時出錯

我在Spring引導異常處理中試圖伸出援手。我已經創建了一個REST應用程序，並且該應用程序適用於所有有效的url。我想處理無效網址的例外情況。但如果我嘗試打網址無效的申請，我得到以下異常： -爲Spring Boot REST應用程序處理404錯誤時出錯

作爲新的春天開機我無法找出原因。任何指針或建議都會有幫助。

想試試本網站中提到的選項enter link description here，一旦我能夠刪除異常。

任何關於如何在Spring 4中處理404註釋的指針都會非常有幫助。

試行下面的代碼： -

@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); 
       } 
      }; 
     }

從pom.xml中添加的依賴性

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

      </exclusions> 
     </dependency>

     <dependency> 
      <groupId>org.springframework.boot</groupId>

應用離子適用於有效的URL映射。它使用彈簧引導來構建。 PFB應用註釋類： -

@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); 
    } 

}

得到它爲我用一個簡單的404也許是時候分享整個項目和一些步驟來重現後此鏈接？ – 2014-09-02 13:58:43

我有一些工作，但不完全。刪除@EnableWebMvc後，我沒有收到錯誤。我得到了默認的Whitemarker頁面。 – Manu 2014-09-04 11:48:34

你需要打開一下。是否有堆棧跟蹤？ – 2014-09-04 21:09:58

如果404發生，我已經添加了映射到重定向到自定義html頁面。 PFB爲此所做的更改：

從 WebConfig.java類中刪除了Annotation @EnableWebMvc。這樣做是爲了消除錯誤「響應已經提交」，嘗試任何無效的網址。

添加以下代碼WebConfig.java類和亡魂的html頁面：

@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); 
     } 
    }; 
}

非常感謝您的建議答熟知。這非常有用。

我也跟着通過初步exeception

你可以按照下面的博客來處理MVC異常處理

我無法按照鏈接中的步驟操作，因爲當我嘗試使用未知網址時，出現上述錯誤。 – Manu 2014-09-01 13:44:37

我已經在問題中給出了同樣的鏈接作爲我的參考。如果有關於例外的任何信息，請告訴我。 – Manu 2014-09-01 15:42:57

升級到春季啓動1.1.5.RELEASE。

使用最新版本 – Manu 2014-09-01 19:42:32

感謝Dave Syer的建議。使用最新版本的spring boot.I已經從pom.xml添加了spring引導依賴關係。但是沒有運氣......相同錯誤 – Manu 2014-09-02 05:50:14

堆棧跟蹤仍然顯示1.1.4。如果你還沒有更新，你還能更新嗎？ – 2014-09-02 06:18:55
