java - 线程 "main"java.lang.NoClassDefFoundError : org/springframework/core/metrics/ApplicationStartup 中出现异常

Question

我目前正在尝试将我的一个 Spring 应用程序从 java 8 -> 11 升级，但在启动时遇到此错误:

Exception in thread "main" java.lang.NoClassDefFoundError: org/springframework/core/metrics/ApplicationStartup
at org.springframework.boot.SpringApplication.<init>(SpringApplication.java:254)
at org.springframework.boot.SpringApplication.<init>(SpringApplication.java:267)
at org.springframework.boot.SpringApplication.run(SpringApplication.java:1329)
at org.springframework.boot.SpringApplication.run(SpringApplication.java:1318)

这些是我的 pom 文件中的所有 spring 依赖项:

        <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-devtools</artifactId>
        <optional>true</optional>
    </dependency>
    <dependency>

    </dependency>

    <dependency>
        <groupId>io.springfox</groupId>
        <artifactId>springfox-swagger2</artifactId>
        <version>${springfox.version}</version>
    </dependency>

    <dependency>
        <groupId>io.springfox</groupId>
        <artifactId>springfox-swagger-ui</artifactId>
        <version>${springfox.version}</version>
    </dependency>

连同 Spring Boot Starter 父版本: 2.4.6

我不确定还需要什么其他信息让我知道

Answer 1

您是否尝试过指定较低版本的依赖项？

我认为这个问题出在 2.4.X 上

据我所知，2.3.X 不会导致任何问题。

<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-web</artifactId>
  <version>2.3.3.RELEASE</version>
</dependency>
