1.3.7.RELEASE -> 1.4.1.RELEASE | java.lang.NoSuchMethodError: org.springframework.boot.builder.SpringApplicationBuilder.showBanner

Question

If I switch to the new version of SpringBoot, I get the above error message when starting the application. Why is that?

Best wishes Steven

Answer 1

I was able to resolve this by explicitly declaring the cloud-context dependency which works for version 1.4.4

    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-context</artifactId>
        <version>1.1.8.RELEASE</version>
    </dependency>

When working with Spring Boot 1.4.1.RELEASE, they have changed it from

new SpringApplicationBuilder().showBanner()

to

new SpringApplicationBuilder().bannerMode(Banner.Mode bannerMode)

where Banner.Mode bannerModeexpects an enum for either: Console, Log, or Off.

examples:

new SpringApplicationBuilder().bannerMode(Banner.Mode.CONSOLE); //Prints banner to System.out

new SpringApplicationBuilder().bannerMode(Banner.Mode.LOG); //Prints banner to the log file

new SpringApplicationBuilder().bannerMode(Banner.Mode.OFF); //Disables the banner

If you are looking for the banner to be printed, go with the first one, Banner.Mode.CONSOLE

Your new main method would look like this:

public static void main(String[] args){

    //SpringApplicationBuilder() returns an ApplicationContext, but creating the variable is optional
    ApplicationContext ctx = new SpringApplicationBuilder().bannerMode(Banner.Mode.CONSOLE).run(args);

    //Now, if you need to do something else with the ApplicationContext, you can (such as print all the beans, etc.)
}

Here is the java doc to the SpringApplicationBuilder:

http://docs.spring.io/spring-boot/docs/current/api/org/springframework/boot/builder/SpringApplicationBuilder.html#bannerMode-org.springframework.boot.Banner.Mode-

And here is the java doc explaining the Banner.Mode Enum:
