java.lang.NoSuchFieldError : APPLICATION_CONTEXT_ID_PREFIX 错误

Question

我在运行我的项目时收到此错误，结果最终是 404。该项目是在Spring框架上制作的。

我看了很多帖子，发现要么混装了 jar，要么有多余的 jar。之后我试着整理我的 jar 。以下列表是我的构建路径中的内容:

我删除了很多 jar ，我认为它们是重复的。
我的问题是所有这些 jar 是否完全足够或是否有重复？
请帮忙，这个 404 快要死了...

Answer 1

那里有很多重复的 jar :

antlr
jta
mysql-connector
javassist
mssqlserver

在继续之前，我会确保您只有一个版本，找出您需要的版本并包括那个版本。

如果您不确定如何执行此操作，请告诉我们您是如何导入依赖项的。

查看您所看到的堆栈跟踪以及导致错误的简化 Spring 上下文也会很有帮助。

如果你看这个问题:JasperException: absolute uri: http://java.sun.com/jsp/jstl/core cannot be resolved

您需要确保您拥有正确版本的 JSTL，也许一旦您删除了重复的 JSTL，它可能会修复该错误。
