Question

我正在尝试使用MongoDB存储库设置Javers。我对javers-core和javers-persistence-mongo使用版本2.9.1。

但是，当我尝试使用布尔字段提交实体时，会抛出以下异常：

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)中的javers-persistence-mongo-2.9.1/DocumentConverter方法，只有JsonPrimitives String和Number（非布尔值）的转换方法。

我在这里错过了一些配置吗？

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2.9.1中引入的错误。观看此问题https://github.com/javers/javers/issues/494

中修复进度的错误

（编辑）的修正于2.9.2

Javers MongoRepository为布尔JsonPrimitive
