Vaadin Spring/Boot and Spring Boot versions compatibility

Flow
1

Hello all,

is there anywhere any documentation on which version works with which version?



Currently in our project this works fine:

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.4.4.RELEASE</version>
</parent>

    <dependency>
            <groupId>com.vaadin</groupId>
            <artifactId>vaadin-spring-boot-starter</artifactId>
            <version>1.1.1</version>
    </dependency>
    <dependency>
            <groupId>com.vaadin</groupId>
            <artifactId>vaadin-spring</artifactId>
            <version>1.1.1</version>
    </dependency>

If we try to use vaadin.spring boot 2.0 and/or anything higher than Spring Boot 1.4.4.RELEASE then the project crashes at startup (with different errors on different version combinations)



the following combination (all latest versions)

[code]

org.springframework.boot
spring-boot-starter-parent
1.5.1.RELEASE

<dependency>
        <groupId>com.vaadin</groupId>
        <artifactId>vaadin-spring-boot-starter</artifactId>
        <version>2.0.0</version>
</dependency>
<dependency>
        <groupId>com.vaadin</groupId>
        <artifactId>vaadin-spring</artifactId>
        <version>2.0.0</version>
</dependency>

[/code]start ups succesfully but when loading the application’s url crashes in our class that extends SpringVaadinServlet when we call

super.servletInitialized(); in the constructor complaining that the method does not exist…



the following combination (spring boot latest and vaadin spring/boot 1.1.0)

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.1.RELEASE</version>
</parent>

    <dependency>
            <groupId>com.vaadin</groupId>
            <artifactId>vaadin-spring-boot-starter</artifactId>
            <version>1.1.0</version>
    </dependency>
    <dependency>
            <groupId>com.vaadin</groupId>
            <artifactId>vaadin-spring</artifactId>
            <version>1.1.0</version>
    </dependency>

crashes on startup with

java.lang.NoClassDefFoundError: org/springframework/boot/context/embedded/ServletRegistrationBean Can anyone please enlight us on the compatible combinations?

Regards.

Make sure that you have the correct versions of all the relative libraries.

For example

<parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.5.1.RELEASE</version> </parent> works strictly with

<dependency> <groupId>com.vaadin</groupId> <artifactId>vaadin-spring-boot-starter</artifactId> <version>1.2.0</version> </dependency> <dependency> <groupId>com.vaadin</groupId> <artifactId>vaadin-spring</artifactId> <version>1.2.0</version> </dependency> However,

it seems that the class you miss is part of the core framework. Which versions of Vaadin, Spring Boot and Vaadin Spring Boot add-on you are using?

please post your pom.xml file
