dependency 'org.springframework:spring-webmvc:' not found

该错误提示意味着未找到名为 'org.springframework:spring-webmvc:' 的依赖项。这是因为在使用Spring框架的Web应用程序时,需要添加spring-webmvc依赖项。通常,这是通过在构建工具或项目配置文件中指定依赖项来实现的。如果您正在使用Maven,则可在pom.xml文件中添加以下代码:
```
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>{your-version-number}</version>
</dependency>
```
其中版本号应替换为您所需的Spring版本号。如果您使用Gradle,则可以添加以下内容到build.gradle文件中:
```
dependencies {
implementation 'org.springframework:spring-webmvc:{your-version-number}'
}
```
在执行依赖项下载和同步之后,应该就能够解决该错误。

当出现依赖不能自动下载的情况时,有几个可能的原因可以考虑。首先,你可以确认你的Maven配置是否正确。你可以检查你的`settings.xml`文件中是否正确配置了远程仓库,以便Maven能够下载依赖。此外,你还可以尝试运行`mvn clean install`命令来清除本地仓库并重新下载依赖。
另一个可能的原因是插件的冲突。有时候某些插件可能会与你的依赖冲突,导致无法正确下载。你可以尝试卸载或禁用这些插件,然后再次尝试下载依赖。例如,在你的情况下,卸载或禁用MybatisX插件可能会解决问题。
最后,确保你的依赖信息正确无误。检查你的`pom.xml`文件中是否正确声明了依赖项,包括`org.springframework.cloud:spring-cloud-starter-bootstrap:3.1.0`。你可以尝试手动添加依赖,并再次运行Maven来下载它。
综上所述,当遇到依赖不能自动下载的情况时,你可以尝试以下步骤:
1. 检查Maven配置是否正确,包括远程仓库的配置。
2. 运行`mvn clean install`命令来清除本地仓库并重新下载依赖。
3. 卸载或禁用可能与依赖冲突的插件。
4. 确保`pom.xml`文件中依赖信息的正确性,并尝试手动添加依赖。
通过以上步骤,你应该能够解决依赖不能自动下载的问题并成功引入依赖。<span class="em">1</span><span class="em">2</span><span class="em">3</span>

org.springframework.web.util.NestedServletException: Handler dispatch failed; nested exception is java.lang.NoClassDefFoundError:
org/springframework/web/servlet/DispatcherServlet
This exception is thrown when the handler dispatch fails in a Spring web application. The nested exception, java.lang.NoClassDefFoundError, indicates that a class required by the application could not be found at runtime.
In this specific case, the missing class is org.springframework.web.servlet.DispatcherServlet. This class is part of the Spring MVC framework and is responsible for handling requests in a web application.
To resolve this issue, you need to ensure that the necessary Spring MVC dependencies are present in your application's classpath. Make sure that you have included the required Spring MVC JAR files in your project's dependencies or build configuration.
If you are using a dependency management tool like Maven or Gradle, you can add the necessary dependencies to your project's configuration file. For example, in Maven, you can add the following dependency to your pom.xml file:
```xml
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>{version}</version>
</dependency>
```
Replace `{version}` with the desired version of the Spring framework.
If you are not using a dependency management tool, you will need to manually download the required JAR files and add them to your project's classpath.
Once you have ensured that the necessary dependencies are present, rebuild and redeploy your application to see if the issue is resolved.
