Description:

An attempt was made to call a method that does not exist. The attempt was made from the following location:

    org.springframework.boot.env.OriginTrackedYamlLoader.createYaml(OriginTrackedYamlLoader.java:69)

The following method did not exist:

    org.yaml.snakeyaml.LoaderOptions.setMaxAliasesForCollections(I)V

The method's class, org.yaml.snakeyaml.LoaderOptions, is available from the following locations:

    jar:file:/home/Rabbit/.m2/repository/org/yaml/snakeyaml/1.25/snakeyaml-1.25.jar!/org/yaml/snakeyaml/LoaderOptions.class

The class hierarchy was loaded from the following locations:

    org.yaml.snakeyaml.LoaderOptions: file:/home/Rabbit/.m2/repository/org/yaml/snakeyaml/1.25/snakeyaml-1.25.jar


Action:

Correct the classpath of your application so that it contains a single, compatible version of org.yaml.snakeyaml.LoaderOptions


Process finished with exit code 1

解决方法：

可能是版本问题，

将

<dependency>
   <groupId>org.yaml</groupId>
   <artifactId>snakeyaml</artifactId>
   <version>1.25</version>
</dependency>

中的版本号去掉就好，使SpringBoot自动获取需要的版本。

<dependency>
   <groupId>org.yaml</groupId>
   <artifactId>snakeyaml</artifactId>
</dependency>
