java - 升级到 Java 8 导致单元测试中的 Orika 映射器 java.io.IOException : invalid constant type: 15 at 142

Question

我有一个项目，我想将版本从 Java 1.7 更新到 Java 1.8，但是运行单元测试时所有映射器测试都失败了。

该项目正在使用:SpringJUnit4ClassRunner

<dependency>
    <groupId>ma.glasnost.orika</groupId>
    <artifactId>orika-core</artifactId>
    <version>1.4.5</version>
</dependency>

对于那部分异常:嵌套异常是 ma.glasnost.orika.MappingException: java.lang.RuntimeException: java.io.IOException: invalid constant type: 15 at 142我找到了你这个 SO 帖子: Reflections - Java 8 - invalid constant type
但我不确定这是否真的是问题所在，因为我不依赖于“javassist”。

这是否与同一问题有关？我怎样才能克服它？

Answer 1

您的想法朝着正确的方向发展。

java.lang.RuntimeException: java.io.IOException: invalid constant type: 15 at 142表明该应用程序存在 Java 8 问题 - 如您的链接所述。

ma.glasnost.orika 映射器依赖于 javassist，如您在 Stack Trace 中所见。这是 orika 的传递依赖。

您可以使用mvn dependency:tree -verbose 来构建依赖树。在那里你可以查看什么库取决于 javassist 和确切的版本。

要使用与 Java 8 兼容的 javassist 版本，请使用该依赖项来覆盖 orika 的隐式依赖项:

  <dependency>
    <groupId>org.javassist</groupId>
    <artifactId>javassist</artifactId>
    <version>3.18.2-GA</version>
  </dependency>

但对于此示例，最好将 orika 版本升级到 1.4.6，因为它已准备好 Java 8。
