Java how to disable the auto-configuration?

To disable the auto-configuration in Java, you can use the -noverify command-line option when running the Java virtual machine (JVM). This option disables the bytecode verifier, which is responsible for checking the integrity of the class files and ensuring that they conform to the Java Virtual Machine Specification.

Here's an example of how to use the -noverify option to disable the auto-configuration:

java -noverify MyClass

Note that disabling the bytecode verifier can potentially allow malicious code to run on the JVM, so it is not recommended to use the -noverify option unless you have a specific reason to do so.

Alternatively, you can disable the auto-configuration by setting the spring.autoconfigure.exclude property in the application's configuration file (e.g., application.properties). This property specifies a list of classes or packages that should be excluded from the auto-configuration process.

Here's an example of how to use the spring.autoconfigure.exclude property to disable the auto-configuration:

spring.autoconfigure.exclude=org.example.MyClass,org.example.package

The above example excludes the MyClass class and the package package from the auto-configuration process. You can specify multiple classes or packages by separating them with a comma.

Note that disabling the auto-configuration can prevent certain features or functionality from being configured automatically, so it is not recommended to use this approach unless you have a specific reason to do so.
