如何使用 java 设置 spring-boot 应用程序 13

Question

I am creating a spring-boot application, which is running and performing well with openJdk12. The application: https://github.com/jactor-rises/jactor-persistence

I am looking for how to set it up with openJdk13.

I tried with spring-boot 2.1.8.RELEASE and 2.1.9.RELEASE , but both versions fails runtime with an IllegalStateException :

java.lang.IllegalStateException: Failed to load ApplicationContext

Answer 1

You should migrate to using spring-boot 2.2.0 which includes the migration to using Spring Framework 5.2.0 which extends supports until Java-14.

Reference - Spring-Framework-Versions#jdk-version-range

Here are the Draft Release Notes for further information and references and the current version to test this out would be 2.2.0-RC1 .

Update [16 October, 2019] : Spring Boot 2.2.0 has been released.

Answer 2

As mentioned here , you can migrate your project to Spring boot version 2.2.0.
Also, you need to upgrade your build tool(Here I have used Gradle).
Sample project:Github

1. Get/update gradle to 6.0-rc-1 , make sure you point to java-8/11(ie JAVA_HOME is set to java-8/11) until you upgrade gradle.
   ./gradlew wrapper --gradle-version=6.0-rc-1 --distribution-type=all
   There is known bug , bug-1 for gradle with java-13, which is fixed in 6.0-rc-1 version.

2. Get OpenJDK-13 from here , set JAVA_HOME to java-13

3. As mention by @dirk-deyne in comment update ASM too, Ref
4. Build your project

PS If you use https://start.spring.io/ , make sure you select java version 13.
