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

根据提供的引用内容，出现org.springframework.web.util.NestedServletException: Handler dispatch failed; nested exception is java.lang.NoClassDefFoundError: ?的原因是缺少某个类的定义。具体缺少哪个类需要根据实际情况进行排查。

解决该问题的方法是找到缺少的类并将其添加到项目依赖中。可以通过引入相关的jar包或者maven依赖来解决该问题。

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

这个错误信息表明在处理请求时发生了异常。具体来说，是由于找不到相关的类而导致的NoClassDefFoundError。引用中提到了找不到org/apache/commons/httpclient/HttpClient类，引用中提到了找不到com/alibaba/fastjson/JSON类，引用中提到了找不到org/apache/velocity/context/Context类。这些错误可能是由于引入的依赖包版本不匹配或者缺失导致的。解决这个问题的方法是检查项目的依赖配置是否正确，确保所需的类库在项目中可用，并且版本兼容。另外，还需要确保所使用的IDE或构建工具正确地引入了所需的依赖包。<em>1</em><em>2</em><em>3</em>

例外情况 org.springframework.web.util.NestedServletException: Handler dispatch failed; nested exception is java.lang.StackOverflowError

引用中的异常信息表明，在处理程序分发时发生了异常，导致嵌套的例外情况。具体的异常是java.lang.NoClassDefFoundError: org/apache/velocity/context/Context。这个异常通常是因为缺少了org/apache/velocity/context/Context类所在的jar包或者类路径配置错误所导致的。可能需要添加正确的jar包或者检查类路径配置是否正确。

在引用中也提到了类似的异常，即java.lang.NoClassDefFoundError: org/apache/velocity/context/Context。这意味着在处理程序分发时发生了一个ClassNotFoundException，无法找到org/apache/velocity/context/Context类。

至于例外情况org.springframework.web.util.NestedServletException: Handler dispatch failed; nested exception is java.lang.StackOverflowError，这个异常表示在处理程序分发时发生了一个栈溢出错误。栈溢出错误通常是由于递归调用或者无限循环导致的。可以检查代码中是否存在无限循环或者递归调用的情况，以及检查是否有其他导致栈溢出的原因。

综上所述，发生了org.springframework.web.util.NestedServletException: Handler dispatch failed; nested exception is java.lang.StackOverflowError异常，可能与缺少org/apache/velocity/context/Context类相关的jar包或者类路径配置错误有关。此外，还需要检查是否存在导致栈溢出的代码逻辑问题。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
