升级到Java 8会导致unittest java.io.IOException中的Orika映射器：无效的常量类型：15 at 142

Question

我有一个项目，希望将版本从Java 1.7更新到Java 1.8，但是运行UnitTests时所有映射器测试均失败。

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：nested exception is ma.glasnost.orika.MappingException: java.lang.RuntimeException: java.io.IOException: invalid constant type: 15 at 142 我在一个SO帖子上找到了： 反射-Java8-无效的常量类型
但是我不确定这是否真的是问题，因为我不依赖于’javassist’。

这是否与同一个问题有关？我该如何克服？

更完整的StackTrace：

Answer 1

您的想法朝着正确的方向发展。

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

如您在堆栈跟踪中所见，ma.glasnost.orika映射器取决于javassist。这是orika的传递依赖。

您可以mvn dependency:tree -verbose用来构建依赖关系树。在这里，您可以查找依赖于Javassist的库以及确切的版本。

要使用兼容Java 8的javassist版本，请使用该依赖关系来覆盖orika的隐式依赖关系：

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

但是对于此示例，最好将orika版本升级到1.4.6，因为该版本已支持Java 8。
