java.io.IOException：无效的常量类型：19 at 5

我有一个项目 。 它使用spring boot 2 ， java 9和maven。 它可以使用mvn clean package成功构建。

要运行spring boot应用程序，我使用了该命令

 java -jar java-cloud-rest-api/target/java-cloud-rest-api-0.0.1-SNAPSHOT.jar 

但它失败了，错误

我为start命令添加了额外的参数

 java --add-modules java.xml.bind -jar java-cloud-rest-api/target/java-cloud-rest-api-0.0.1-SNAPSHOT.jar 

但是当我运行它时，我得到了这个错误

问题是什么？

Answer 1

虽然这不能解决如何解决这个问题，但如JDK-8161256中所述，关于常量池标记：

Java 9使用代码19和20作为模块系统。

当前javassist创建ClassFile的方式是使用readOne方法查找ConstantPool （表直到Java8）， readOne方法肯定缺少类似于最新java版本的Module 。 您对javassist依赖关系层次结构：

• org.springframework.boot：弹簧引导起动器中：jar：2.0.0.M3：编译

  • org.springframework.boot：弹簧引导起动数据JPA：jar子：2.0.0.M3：编译

    • org.hibernate作为：hibernate核心：jar子：5.2.10.Final：编译

      • org.javassist：Javassist是：jar子：3.21.0-GA：编译

看看javassist方面的事情：

• 似乎在javassist / issues＃147上注册了类似的错误。

• 它们的rel_3_22_0_cr2 （最后一个版本）读取与Java 9-ea + 164兼容。 此版本的javassist也会出现同样的问题。

• 因此，您可以等待javassist通过解决方案回过头来。
