java.lang.ClassNotFoundException: org.springframework.cache.guava.GuavaCache

Question

背景-

我有一个spring引导应用程序，我将spring-boot-starter-parent版本从1.5.12.RELEASE更新到2.4.0

我的酒里有这种依赖性-

<dependency>
    <groupId>com.google.guava</groupId>
    <artifactId>guava</artifactId>
    <version>30.1-android</version>
</dependency>

现在当我运行我的应用程序时，我得到了这个错误-

    org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'cachesEndpoint' defined in class path resource ...

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'guavaCacheManager' defined in class path resource...

Answer 1

我通过从我的项目中完全消除番石榴依赖及其引用来解决这个问题。

如果您仍然需要使用缓存，那么尝试使用咖啡因。

Answer 2

通过在网络上进行更多的研究，我能够通过向项目添加spring上下文支持来修复在我的项目中发生的相同的异常。我是通过向我的build.gradle添加以下依赖项来做到这一点的

compile("org.springframework:spring-context-support:4.1.7.RELEASE")

spring-context-support是一个库，它包含用于配置缓存的助手方法和类。
