Spring Boot升级后“未找到提供程序com.fasterxml.jackson.module.jaxb.JaxbAnnotationModule”

Question

当我尝试启动应用程序时，在将Spring Boot从2.1.5升级到2.2.2之后，我收到了这个异常消息。

当我刚刚升级到SpringBoot2.2.1时，这个异常不会发生。

添加依赖项后：

<dependency>
      <groupId>com.fasterxml.jackson.module</groupId>
      <artifactId>jackson-module-jaxb-annotations</artifactId>
</dependency>

它适用于2.2.2。

所以我的问题是，为什么在这次Spring Boot升级之后突然需要手动添加依赖项。

Answer 1

假设您的应用程序正在使用/包括Liquibase，这是因为Liquibase core中有一个错误的文件，该html" target="_blank">文件正在为Jackson模块定义SPI扩展名，但没有为该模块提供实现：https://github.com/liquibase/liquibase/issues/1051

OP中列出的解决方案已经足够了，因为它为SPI文件中引用的Jackson模块提供了实现，但是您也可以将Liquibase升级到

对于Gradle，依赖关系是：

implementation 'org.liquibase:liquibase-core:3.10.3'

Answer 2

我将研究您的依赖项，它们可能使用xml作为配置。我使用的是SpringBoot2.3.1，在添加Liquibase支持之前，我不需要这个依赖项。因为我使用xml进行Liquibase配置，所以在启动时看到了相同的错误。一旦我添加了这个依赖项，错误就消失了。
