如何使用 java 设置 spring-boot 应用程序 13

Question

我正在创建一个 spring-boot 应用程序，它与 openJdk12 一起运行并表现良好。 应用程序： https://github.com/jactor-rises/jactor-persistence

我正在寻找如何使用 openJdk13 进行设置。

我尝试使用 spring-boot 2.1.8.RELEASE和2.1.9.RELEASE ，但两个版本都因IllegalStateException运行时失败：

Answer 1

您应该迁移到使用spring-boot 2.2.0 ，其中包括迁移到使用Spring Framework 5.2.0 ，它将支持扩展到 Java-14。

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

以下是发行说明草案以获取更多信息和参考，当前测试版本为2.2.0-RC1 。

更新 [2019 年 10 月 16 日] ： Spring Boot 2.2.0已发布。

Answer 2

如此处所述，您可以将您的项目迁移到 Spring 引导版本 2.2.0。
此外，您需要升级构建工具（这里我使用了 Gradle）。
示例项目：Github

1. 获取/更新 gradle 到6.0-rc-1 ，确保指向 java-8/11（即 JAVA_HOME 设置为 java-8/11），直到升级 gradle。
   ./gradlew wrapper --gradle-version=6.0-rc-1 --distribution-type=all
   gradle 和 java-13 存在已知的bug ， bug-1 ，在 6.0-rc-1 版本中已修复。

2. 从这里获取 OpenJDK-13，将 JAVA_HOME 设置为 java-13

3. 正如@dirk-deyne 在评论更新 ASM 中提到的那样，参考
4. 构建你的项目

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