Javers为布尔JsonPrimitive抛出IllegalArgumentException

Question

我正在尝试使用MongoDB存储库来设置Javer。我正在为javers-core和javers-persistence-mongo使用2.9.1版本。

但是，当我尝试提交带有布尔字段的实体时，会引发以下异常：

java.lang.IllegalArgumentException: unsupported JsonElement type - JsonPrimitive

    at org.javers.core.JaversCore.commit(JaversCore.java:65) ~[javers-core-2.9.1.jar:?]

查看private static Object fromJsonElement(JsonElement jsonElement)方法在javers-persistence-mongo-2.9.1/DocumentConverter中，只有JsonPrimitives字符串和数字的转换方法(而不是布尔值)。

我是不是漏掉了什么配置？

MWE：

  public static void main(final String[] args) {
    final TestEntity testEntity = new TestEntity();
    testEntity.id = 12345L;
    testEntity.testBoolean = true;

    final MongoClient mongoClient = new MongoClient(...);
    final Javers javers = JaversBuilder.javers()
        .registerJaversRepository(new MongoRepository(mongoClient.getDatabase(...))).build();

    javers.commit("testAuthor", testEntity); // Throws IllegalArgumentException
  }

  @Entity
  static class TestEntity {

    @Id
    Long id;

    Boolean testBoolean;
  }

这是在2.9.1中引入的一个bug。查看此问题中的错误修复进度，https://github.com/javers/javers/issues/494
