java - JsonMappingException 的 Spring Boot 测试给出了低于标准的堆栈跟踪

Question

Spring 集成测试，定义为

@RunWith(SpringRunner.class)
@SpringBootTest(classes = HiVssFormioWrapperApplication.class, webEnvironment = WebEnvironment.DEFINED_PORT)
@TestPropertySource(locations= {"classpath:application.properties", "classpath:application-integration-test.properties"})

最近开始失败，但是堆栈跟踪几乎没有提供有关在哪里查找的线索。它确实指出了问题所在，但没有指出问题所在。这是完整的堆栈跟踪，请注意实际上没有一个堆栈跟踪元素指向我们的代码:

我对 MultipleFailuresError 表示怀疑，因为它可能会吞噬正确的堆栈跟踪，但谷歌搜索“disable junit MultipleFailuresError”并没有带来任何有用的东西。

这可能不是 Eclipse 的问题，因为从命令行使用 Maven 运行会给出类似的结果。

使用的版本是

• Java:OpenJDK13

• SpringBoot:2.2.0.RELEASE

  查看依赖关系层次结构，这会带来

  • junit 4.12
  • jackson 2.10
• Vavr:0.10

Answer 1

异常(exception)情况是 JSON Serializer Jackson 无法序列化 Vavr List 类。

您必须添加 Vavr Jacksion 支持才能使其正常工作。

    <groupId>io.vavr</groupId>
    <artifactId>vavr-jackson</artifactId>
    <version>0.10.2</version>
