我正在尝试在我们拥有的多个项目中将spring从2.1.1升级到2.2.0。我已经做了几个项目，一切顺利。

在当前的项目中，我做了同样的更改：

代码语言：javascript
复制
<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.2.0.RELEASE</version>
        <relativePath/>
</parent>

<properties>
        <spring-cloud.version>Hoxton.RELEASE</spring-cloud.version>
        <spring.boot.version>2.2.0.RELEASE</spring.boot.version>
    ...
    ...

</properties>

<dependencyManagement>
        <dependencies>
            <dependency>
                <!-- Import dependency management from Spring Boot -->
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-dependencies</artifactId>
                <version>${spring.boot.version}</version>
            </dependency>
        .....
        .....
</dependencyManagement>

<dependencies>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-core</artifactId>
        </dependency>
...
</dependencies>

现在，当我尝试启动我的应用程序时，我得到了以下错误：

代码语言：javascript
复制
Caused by: java.lang.NoClassDefFoundError: org/springframework/core/annotation/MergedAnnotations$SearchStrategy

我检查了这个类，根据文档，这个类在我当前的spring版本中是可用的：https://docs.spring.io/spring/docs/5.2.0.RELEASE/javadoc-api/org/springframework/core/annotation/MergedAnnotations.SearchStrategy.html。

参考资料：文档

当在没有版本的情况下声明作为Spring平台一部分的工件时，将使用依赖项的预定义版本，而对于spring-core则是这样。

org.springframework弹簧-芯5.0.13

https://docs.spring.io/spring/docs/5.0.13.RELEASE/javadoc-api/org/springframework/core/annotation/缺少MergedAnnotations类。

使用所选版本声明依赖项。

代码语言：javascript
复制
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-core</artifactId>
        <version>5.2.0.RELEASE</version>
    </dependency>

更新(我先前的回答似乎有点误导)

明确声明版本并不是必需的。文档的依赖性管理部分提到了以下内容。

Spring的每个版本都提供了它支持的依赖项的管理列表。实际上，您不需要在构建配置中为这些依赖项中的任何一个提供版本，因为Spring为您管理这些依赖关系。升级Spring本身时，这些依赖项也会以一致的方式升级。

此外，还解释了在继承初学者父级时所需的升级修改( 这里 )
