由以下原因引起：java.lang.ClassNotFoundException：升级到 Java 11 后 IntelliJ 中的 com.fasterxml.jackson.databind.ObjectMapper
Caused by: java.lang.ClassNotFoundException: com.fasterxml.jackson.databind.ObjectMapper in IntelliJ after upgrading to Java 11
升级到 Java 11 和 Spring Boot 2.2.6 / Jackson 2.10.3 后，我无法在 Intellij 中启动我的应用程序。 运行 用 Maven 编译后 java -jar app.jar 它工作得很好。
尽管在 IntelliJ 中尝试 运行 时，我收到以下错误：Caused by: java.lang.ClassNotFoundException: com.fasterxml.jackson.databind.ObjectMapper

我已经尝试删除 Jackson 依赖项，但没有任何变化。
我觉得问题很简单。您正在从您的代码生成一个 jar，但问题是当创建这样的 jar 时，您需要注意在 CLASSPATH 中提供您的第 3 方依赖项，否则如果在执行您的 jar 时找不到所需的，则可能会抛出上述错误外部 类.
现在让我们看看您上面描述的两种方式：
java -jar app.jar 这将打包您当前的代码并需要将适当的文件添加到 CLASSPATH。
现在，当您通过 Maven 生成 jar 时，它会下载所需的第 3 方 类，然后将您的应用程序打包到之前提到的已下载 类 的 jar 中。因此，当 运行 那个 jar 时，所有需要的 类 都会出现。
问题是我的 jackson 依赖项中的 <scope>compile</scope> 丢失了。
它是这样工作的：
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-annotations</artifactId>
<version>2.11.0</version>
<scope>compile</scope>
</dependency>
我还必须添加具有相同范围的 classmate：
<dependency>
<groupId>com.fasterxml</groupId>
<artifactId>classmate</artifactId>
<version>1.5.1</version>
<scope>compile</scope>
</dependency>
最后，我不得不将这两个条目添加到我的 module-info.java 文件中：
open module gui {
...
requires com.fasterxml.classmate;
}
和
module core_entity {
requires com.fasterxml.jackson.annotation;
requires com.fasterxml.jackson.core;
...
}
请注意额外的 com.fasterxml.jackson.core 要求，尽管没有这种明确的 maven 依赖性。

这是我的家属：

我已经尝试删除 Jackson 依赖项，但没有任何变化。
我觉得问题很简单。您正在从您的代码生成一个 jar，但问题是当创建这样的 jar 时，您需要注意在 CLASSPATH 中提供您的第 3 方依赖项，否则如果在执行您的 jar 时找不到所需的，则可能会抛出上述错误外部 类.
现在让我们看看您上面描述的两种方式：
java -jar app.jar这将打包您当前的代码并需要将适当的文件添加到 CLASSPATH。现在，当您通过 Maven 生成 jar 时，它会下载所需的第 3 方 类，然后将您的应用程序打包到之前提到的已下载 类 的 jar 中。因此，当 运行 那个 jar 时，所有需要的 类 都会出现。
问题是我的 jackson 依赖项中的 <scope>compile</scope> 丢失了。
它是这样工作的：
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-annotations</artifactId>
<version>2.11.0</version>
<scope>compile</scope>
</dependency>
我还必须添加具有相同范围的 classmate：
<dependency>
<groupId>com.fasterxml</groupId>
<artifactId>classmate</artifactId>
<version>1.5.1</version>
<scope>compile</scope>
</dependency>
最后，我不得不将这两个条目添加到我的 module-info.java 文件中：
open module gui {
...
requires com.fasterxml.classmate;
}
和
module core_entity {
requires com.fasterxml.jackson.annotation;
requires com.fasterxml.jackson.core;
...
}
请注意额外的 com.fasterxml.jackson.core 要求，尽管没有这种明确的 maven 依赖性。
