java - Spring Boot升级后的"Provider com.fasterxml.jackson.module.jaxb.JaxbAnnotationModule not found"

Question

将 Spring Boot 从 2.1.5 升级到 2.2.2 后，当我尝试启动应用程序时，收到此异常消息。

当我刚刚升级到 Spring Boot 2.2.1 时，不会出现此异常。

添加依赖后:

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

适用于 2.2.2。

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

Answer 1

我会查看您可能使用 xml 作为配置的依赖项。我正在使用 Spring Boot 2.3.1，并且在添加 Liquibase 支持之前不需要此依赖项。由于我使用 xml 进行 Liquibase 配置，因此我在启动时看到相同的错误。一旦我添加了这个依赖项，错误就消失了。
