我正在尝试在我们现有的多个项目中将spring从2.1.1升级到2.2.0。我已经在几个项目中完成了这项工作,一切都很顺利。
在当前项目中,我做了相同的更改:
<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>${spring.boot.version}</version>
</dependency>
.....
.....
</dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
</dependency>
...
</dependencies>
现在,当我尝试启动我的应用程序时,我遇到以下错误:
Caused by: java.lang.NoClassDefFoundError: org/springframework/core/annotation/MergedAnnotations$SearchStrategy
我检查过,根据文档,这个类应该在我当前的spring core版本中可用:https://docs.spring.io/spring/docs/5.2.0.RELEASE/javadoc-api/org/springframework/core/annotation/MergedAnnotations.SearchStrategy.html

参考:文件
当在没有版本的情况下声明Spring IO平台的一部分时,将使用依赖关系的预定义版本,而对于Spring core则是
组织。springframeworkSpring芯5.0.13。发布
https://docs.spring.io/spring/docs/5.0.13.RELEASE/javadoc-api/org/springframework/core/annotation/缺少MergedAnnotions类。
用所选版本声明依赖关系
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>5.2.0.RELEASE</version>
</dependency>
更新(我之前的回答似乎有点误导)
不需要明确声明版本。文档的依赖关系管理部分提到了以下内容。
Spring Boot的每个版本都提供了它所支持的依赖项的详细列表。实际上,您不需要在构建配置中为任何这些依赖项提供版本,因为Spring Boot会为您管理这些依赖项。升级Spring Boot本身时,这些依赖项也会以一致的方式升级。
此外,这里还解释了在插入starter父级时所需的升级修改
我在Ubuntu18.04上使用ELasticsearch。当我尝试运行“./elasticsearch-setup-passwords”脚本时,它显示以下错误。 未来版本的Elasticsearch将需要Java 11;您的Java版本[/usr/lib/jvm/java-8-openjdk-amd64/jre]不符合此要求 但当我检查Jaa版本时,它显示的是Java 11号。 我把Java从8
0.2.X
从 0.8.x, 0.9.x, 0.10.0.x, 0.10.1.x, 0.10.2.x, 0.11.0.x 升级到1.0.0 Kafka 1.0.0 介绍了通信协议方面的改变。 遵循下面的滚动升级计划,可以保证您在升级过程中不用停机。 在升级之前,请先查看1.0.0版本中显著的变化。 滚动升级计划: 更新所有代理上的server.properties 并添加以下属性: CURRENT_KAFKA
无非就3个原因吧 为了fix bug 为了新特性 为了爱,就是要追新 从1.a.38开始的版本,升级到最新版的成本都不大. 做到100%兼容是不现实的,但可以肯定的是, 遇到的问题的均有解决的办法. 有些兼容性问题,属于"错误"得到修正,老版本能这样写是"bug", ^_^ 这是一个汇总帖子,随时更新, 也会按版本的增长继续增长.... 请先浏览当前版本到最新版的发行注记,然后再看本列表 IE下a
MinDoc 根据发布系统功能不同可分为两步进行升级。有些用户可能会自定义了模板,覆盖时请注意备份。尤其是要注意备份配置文件和数据库。 版本查看 通过命令行执行如下命令: ./mindoc version 会看到如下的版本信息: #当前安装的版本版本号 MinDoc current version => v1.0 #最新版本版本号 MinDoc last version => v1.0 一、覆
0.2.X 0.2.2 修改package.json "bui-weex": "^0.2.2" 更新内容 bui-weex无需显式引用,通过 Vue plugin方式注入到全局; 重构组件:弹出框、弹出层、下拉菜单、ActionSheet,并统一使用v-model调用方式; 重构组件:单选、复选等组件,并统一使用v-model调用方式; 重构组件: 选项卡组件,并统一使用v-model调用方式,配
