Resolved [org.springframework.web.util.NestedServletException: Handler dispatch failed; nested exception is java.lang.StackOverflowError

在Spring框架中,当处理请求时,可能会出现异常。其中一个常见的异常是`org.springframework.web.util.NestedServletException`,它表示处理程序调度失败。这个异常通常是由于`java.lang.StackOverflowError`引起的。
`java.lang.StackOverflowError`是一个错误,表示递归调用的堆栈溢出。当一个方法无限递归调用自身或其他方法时,堆栈空间会被耗尽,导致此错误的抛出。
在Spring框架中,`org.springframework.web.util.NestedServletException`通常是由于请求处理程序或拦截器中的无限递归调用导致的。这可能是由于错误的配置、循环依赖或其他代码问题引起的。
要解决这个问题,您可以检查以下几个方面:
1. 检查您的代码,确保没有无限递归调用。
2. 检查您的配置文件,确保没有循环依赖或错误的配置。
3. 检查您的拦截器或过滤器,确保它们没有导致无限递归调用。
如果您仍然无法解决问题,建议您提供更多的代码和错误堆栈信息,以便更好地帮助您分析和解决问题。

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.

Resolved [org.springframework.web.HttpRequestMethodNotSupportedException: Request method 'POST' is not supported] 这个错误通常发生在后台接收到一个不支持的POST请求时。根据你提供的引用,你可以通过给方法参数添加@RequestBody注解来解决此问题。在你的代码中,将方法签名修改为 @PostMapping("/add") public boolean add(@RequestBody Dishes dishes) { return dishesService.save(dishes); } 即可。
