我将Spring Boot从2.1.9升级到2.2.0，现在在启动应用程序时遇到了一些异常
java：openjdk11 春季启动：v2.2.0.RELEASE
我尝试从以下位置删除jar，并进行了mvn全新安装，仍然没有运气。
.m2 / repository / org / springframework / boot / spring-boot-actuator / 2.2.0.RELEASE / spring-boot-actuator-2.2.0.RELEASE.jar

如何解决此问题？
答案 0 :(得分：3)
这似乎是一个已知问题：https://github.com/spring-cloud/spring-cloud-netflix/issues/3410
如果在Spring Boot应用程序中使用Spring Cloud依赖项，请确保在类路径上具有正确的Spring Cloud版本！当前只有Spring Cloud的“ Hoxton”（https://spring.io/blog/2019/08/19/spring-cloud-hoxton-m2-released)发布火车支持Spring Boot 2.2。
答案 1 :(得分：3)
简而言之，问题是由于Spring Cloud和Spring Boot版本不兼容，Spring Boot 2.2.X需要Hoxton发布火车而不是Greenwich。有关更多信息，请参见下文。
此问题归因于spring-cloud.version不兼容。根据Spring Cloud文档链接（https://spring.io/projects/spring-cloud），以下是Spring Boot的兼容性：
发布与Spring Boot的兼容性
Release Train Boot Version
Hoxton 2.2.x
Greenwich 2.1.x
因此，如果您将春季靴子更新为2.2.x，则还要更新到适用于春季云的Hoxton发布系列，即Hoxton.RC1（https://spring.io/blog/2019/10/25/spring-cloud-hoxton-rc1-released）
P.S：根据Spring Cloud Milestone页面Hoxton.RELEASE于2019年11月18日到期（https://github.com/spring-cloud/spring-cloud-release/milestones）
答案 2 :(得分：2)
实际上springfox ist与Spring-Boot 2.2.0不兼容。看来springfox完全死了。
答案 3 :(得分：2)
更新您的springfox-swagger版本。我已经升级了在引导2.2.2下运行的springfox 2.9.2
SpringFox需要版本1.2.0，但Spring Boot 2.2.2本身不会将其引入。因此，您以某种方式在您的类路径中获得了spring-plugin-core-1.2.0.RELEASE，然后它将正常工作
答案 4 :(得分：1)
<springBootVersion>2.2.4.RELEASE</springBootVersion>
受支持的云版本。 Hoxton.M2

答案 5 :(得分：0)
很奇怪。 spring-plugin-core版本应该是2.0.0，而不是1.2.0。让我们升级它：
<!-- https://mvnrepository.com/artifact/org.springframework.plugin/spring-plugin-core -->
<dependency>
<groupId>org.springframework.plugin</groupId>
<artifactId>spring-plugin-core</artifactId>
<version>2.0.0.RELEASE</version>
</dependency>
答案 6 :(得分：0)
添加更新后的plugin-core依赖关系后，我也面临着同样的问题。现在已解决。
<dependency>
<groupId>org.springframework.plugin</groupId>
<artifactId>spring-plugin-core</artifactId>
<version>2.0.0.RELEASE</version>
</dependency>
答案 7 :(得分：0)
如果spring-plugin-core-1.2.0.RELEASE在您的项目中不起作用，那么另一种方法是使用带有 3.0.0-SNAPSHOT 版本的springfox-swagger。对于此版本，它具有不同的存储库。 储存库网址：http://oss.jfrog.org/artifactory/oss-snapshot-local/
它将使用@ EnableSwagger2WebMvc注释而不是@ EnableSwagger2。
答案 8 :(得分：0)
正如 user10871691 和 P3arl 已经指出的那样，spring-plugin-core 依赖项已使用错误的版本 1.2.0.RELEASE 解决。为了强制使用正确的 2.0.0.RELEASE，您必须要么排除错误的传递依赖项并指定正确的传递依赖项，要么在您的 pom.xml 中固定 (!) 该依赖项版本。这是在 <dependenciesManagement> 块中完成的，而不是在 <dependencies> 块中。 Springfox 3.0.0 示例：
<spring-plugin-core.version>2.0.0.RELEASE</spring-plugin-core.version>
<springfox.version>3.0.0</springfox.version>
