Spring Boot not working getting some errors?

问题

以下是您提供的内容的翻译：

请帮助我，因为我无法找出我的Spring Boot应用程序中出现了什么问题。我正在使用以下的pom.xml文件：

  1. <parent>
  2.     <groupId>org.springframework.boot</groupId>
  3.     <artifactId>spring-boot-starter-parent</artifactId>
  4.     <version>2.2.5.RELEASE</version>
  5.     <relativePath/>
  6. </parent>
  7. <properties>
  8.     <java.version>1.8</java.version>
  9.     <spring-boot-starter.version>2.22.0</spring-boot-starter.version>
  10.     <tomcat.version>9.0.37</tomcat.version>
  11. </properties>
  12. <dependencies>
  13.     <dependency>
  14.         <groupId>javax.servlet</groupId>

  22.     </dependency>
  23.     <dependency>

  25.         <artifactId>spring-boot-starter-web</artifactId>
  26.     </dependency>
  27.     <dependency>
  28.         <groupId>org.apache.tomcat.embed</groupId>
  29.         <artifactId>tomcat-embed-jasper</artifactId>
  30.         <scope>provided</scope>
  31.     </dependency>
  32.     <dependency>
  33.         <groupId>org.springframework.boot</groupId>
  34.         <artifactId>spring-boot-devtools</artifactId>
  35.         <scope>runtime</scope>
  36.     </dependency>
  37.     <dependency>
  38.         <groupId>org.springframework</groupId>
  39.         <artifactId>spring-context-support</artifactId>
  40.         <version>5.2.2.RELEASE</version>
  41.     </dependency>
  42. </dependencies>

当我使用Tomcat 9时，会出现以下错误：

  1. java.lang.NoSuchMethodError: javax.servlet.http.HttpServletRequest.getHttpServletMapping()Ljavax/servlet/http/HttpServletMapping;
  2. org.springframework.web.servlet.view.InternalResourceView.renderMergedOutputModel(InternalResourceView.java:171)
  3. ...

而当我使用Tomcat 8时：

  1. <tomcat.version>8.5.50</tomcat.version>

会出现以下错误：

描述：

尝试调用一个不存在的方法。尝试调用的位置为：

org.springframework.boot.web.embedded.tomcat.TomcatServletWebServerFactory.getWebServer(TomcatServletWebServerFactory.java:175)

以下方法不存在：

org.apache.tomcat.util.modeler.Registry.disableRegistry()V

该方法的类，org.apache.tomcat.util.modeler.Registry，可以从以下位置访问：

jar:file:/tomcat/embed/tomcat-embed-core/8.5.50/tomcat-embed-core-8.5.50.jar!/org/apache/tomcat/util/modeler/Registry.class

它是从以下位置加载的：

file:/tomcat/embed/tomcat-embed-core/8.5.50/tomcat-embed-core-8.5.50.jar

请更正应用程序的类路径，以便它包含一个与org.apache.tomcat.util.modeler.Registry兼容的单个版本。

如果有人知道如何解决，请帮助一下。

And when I am using tomcat 8 :

  1. &lt;tomcat.version&gt;8.5.50&lt;/tomcat.version&gt;

it gives me below error:

Description:

An attempt was made to call a method that does not exist. The attempt was
made from the following location:

  1.     org.springframework.boot.web.embedded.tomcat.TomcatServletWebServerFactory.getWebServer(TomcatServletWebServerFactory.java:175)
  3. The following method did not exist:
  5.     org.apache.tomcat.util.modeler.Registry.disableRegistry()V
  7. The method&#39;s class, org.apache.tomcat.util.modeler.Registry, is available from the following locations:
  9.     jar:file:/tomcat/embed/tomcat-embed-core/8.5.50/tomcat-embed-core-8.5.50.jar!/org/apache/tomcat/util/modeler/Registry.class

It was loaded from the following location:

  1.     file:/tomcat/embed/tomcat-embed-core/8.5.50/tomcat-embed-core-8.5.50.jar
  3. Correct the classpath of your application so that it contains a single, compatible version of org.apache.tomcat.util.modeler.Registry

If anyone can knows how to solve it please help.

你的POM文件中包含一些依赖项，这些依赖项之间存在版本冲突。

  1. <dependency>
  2.     <groupId>org.springframework.boot</groupId>
  3.     <artifactId>spring-boot-starter-web</artifactId>
  4. </dependency>

spring-boot-starter-web 的版本 2.3.3.RELEASE 已经内置了 Tomcat 9.0.37。

Tomcat 9 及以上版本使用 servlet 4.x。

从你的 pom.xml 中移除以下依赖项可以解决依赖问题。

  1. <dependency>
  2.     <groupId>org.apache.tomcat.embed</groupId>
  3.     <artifactId>tomcat-embed-jasper</artifactId>
  4.     <scope>provided</scope>
  5. </dependency>

和

  1. <dependency>  
  2.     <groupId>javax.servlet</groupId>  
  3.     <artifactId>javax.servlet-api</artifactId>  
  4.     <version>3.1.0</version>  
  5.     <scope>provided</scope>
  6. </dependency>

因为这些是传递性依赖项，已经被你项目中的其他依赖项提供。

你可以使用 mvn dependency:tree -Dverbose 命令来检查依赖树，以观察潜在的依赖冲突。

英文:

Your POM contains some dependencies that has version conflicts with each other.

  1. &lt;dependency&gt;
  2.     &lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
  3.     &lt;artifactId&gt;spring-boot-starter-web&lt;/artifactId&gt;
  4. &lt;/dependency&gt;

The 2.3.3.RELEASE version of spring-boot-starter-web is already built with Tomcat 9.0.37

Tomcat 9 and above is on servlet 4.x

Removing these the following dependencies from your pom.xml should alleviate your dependency problems.

  1. &lt;dependency&gt;
  2.     &lt;groupId&gt;org.apache.tomcat.embed&lt;/groupId&gt;
  3.     &lt;artifactId&gt;tomcat-embed-jasper&lt;/artifactId&gt;
  4.     &lt;scope&gt;provided&lt;/scope&gt;
  5. &lt;/dependency&gt;

and

  1. &lt;dependency&gt;  
  2.     &lt;groupId&gt;javax.servlet&lt;/groupId&gt;  
  3.     &lt;artifactId&gt;javax.servlet-api&lt;/artifactId&gt;  
  4.     &lt;version&gt;3.1.0&lt;/version&gt;  
  5.     &lt;scope&gt;provided&lt;/scope&gt;
  6. &lt;/dependency&gt;

since these are transitive dependencies that are already provided by dependencies in your project.

You can use mvn dependency:tree -Dverbose to inspect your dependency tree and observe any potential dependency conficts.

  1. 我曾经遇到过类似的问题，原因是 jsp-api 与相应的 servlet-api 版本不匹配。正如 Sven Döring 已经提到的，Spring Boot 2.1.x 使用的是 Tomcat 9，该版本使用/提供 Servlet API v4。因此，您需要 jsp-api 2.3.3，否则可能会出现 NoSuchMethodError。
  3. <dependency>
  4.     <groupId>javax.servlet.jsp</groupId>
  5.     <artifactId>javax.servlet.jsp-api</artifactId>
  6.     <version>2.3.3</version>
  7.     <scope>provided</scope>
  8. </dependency>
  10. 有关版本匹配的更多信息可以在这里找到：
  11. [![enter image description here][1]][1]
  12. 不幸的是，Tomcat 9 和 Servlet-API 4 在此列表中找不到。
  14.   [1]: https://i.stack.imgur.com/SKmRW.png
英文:

I had a similar problem and the cause was the jsp-api didn't fit to the corresponding servlet-api version. As Sven Döring already mentioned Spring Boot 2.1.x uses Tomcat 9 which uses/provides Servlet API v4. For this you need jsp-api 2.3.3 otherwise you can get the NoSuchMethodError.

  1. &lt;dependency&gt;
  2.     &lt;groupId&gt;javax.servlet.jsp&lt;/groupId&gt;
  3.     &lt;artifactId&gt;javax.servlet.jsp-api&lt;/artifactId&gt;
  4.     &lt;version&gt;2.3.3&lt;/version&gt;
  5.     &lt;scope&gt;provided&lt;/scope&gt;
  6. &lt;/dependency&gt;

More info about the version matching can be found here:

Unfortunately Tomcat 9 and Servlet-API 4 is missing in this list.

缺失的方法 HttpServletRequest.getHttpServletMapping() 是在 Servlet API 版本 4 中添加的，因此问题是由于您依赖于 Servlet 3.1 API 引起的：

  1. <dependency>
  2.     <groupId>javax.servlet</groupId>
  3.     <artifactId>javax.servlet-api</artifactId>
  4.     <version>3.1.0</version>
  5.     <scope>provided</scope>
  6. </dependency>

不应该需要声明对 Servlet API 的依赖，因为它已经包含在 spring-boot-starter-web 中。从您的 pom.xml 中移除上述依赖应该可以解决您的问题。

英文:

The method that is missing, HttpServletRequest.getHttpServletMapping(), was added to the Servlet API in version 4 so the problem is caused by your dependency on the Servlet 3.1 API:

  1. &lt;dependency&gt;  
  2.     &lt;groupId&gt;javax.servlet&lt;/groupId&gt;  
  3.     &lt;artifactId&gt;javax.servlet-api&lt;/artifactId&gt;  
  4.     &lt;version&gt;3.1.0&lt;/version&gt;  
  5.     &lt;scope&gt;provided&lt;/scope&gt;
  6. &lt;/dependency&gt;

There should be no need to declare a dependency on the Servlet API as it is already included with spring-boot-starter-web. Removing the above from your pom.xml should fix your problem.
