java - Spring Boot : Unable to load cache item: javax/servlet/Filter

Question

我有一个 Spring Boot 项目并且遇到了一些与 javax servlet 过滤器相关的错误。

是某种版本兼容性还是我在 pom 文件中丢失了某些内容。

以下是来自控制台的日志和 pom 文件。

我一直在寻找，找不到任何东西。

Answer 1

对我来说问题出在 pom 文件中(在 spring boot 2 项目中)，
当我在版本 2.1.9 中使用父 spring boot 时，引擎盖下使用版本 5.1.10.RELEASE 中的 spring-core

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.9.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

我有依赖性:

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-core</artifactId>
            <version>5.2.0.RELEASE</version>
        </dependency>
