nested exception is java.lang.NoClassDefFoundError:org/springframework/web/servlet/ModeAndViewDefiningException

根据提供的引用内容,可以看出出现了一个嵌套异常(nested exception),其中的原因是缺少了一个名为org.springframework.web.servlet.ModeAndViewDefiningException的类。这个类通常是由Spring MVC框架提供的,如果缺少这个类,就会导致程序无法正常运行。
解决这个问题的方法是确保在项目中包含了Spring MVC框架,并且在类路径中包含了org.springframework.web.servlet.ModeAndViewDefiningException类。如果你使用的是Maven或Gradle等构建工具,可以在项目的依赖中添加Spring MVC框架的相关依赖。如果你手动管理依赖,可以将Spring MVC框架的相关jar包添加到类路径中。
另外,如果你已经添加了Spring MVC框架的相关依赖,但仍然出现了这个问题,可能是因为版本不兼容导致的。你可以尝试升级或降级Spring MVC框架的版本,以解决这个问题。

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.
