为什么只有在单元测试时我的Oracle DataSource才会出现重播错误? [英] Why does my Oracle DataSource have a replay error only when unit testing?

问题描述

我的Spring Boot 1.5.17(Spring 4.3.20)服务器可以在bootRun或部署时正常工作.

My Spring Boot 1.5.17 (Spring 4.3.20) server works fine with bootRun or when deployed.

但是，我有一个Oracle DataSource，它仅在单元测试时会失败 :

However, I have an Oracle DataSource that fails only when unit-testing:

java.lang.AssertionError:服务器正在发送非null的重播上下文 但是我们的replayModes = []

java.lang.AssertionError: Server is sending a non-null replay context but our replayModes=[]

针对此错误的Google搜索没有确切结果.

A Google Search for this error doesn't have exact results.

我能够使用其他Oracle数据库进行单元测试.

I am able to unit-test with a different Oracle database.

我在完整的应用程序测试上下文中收到错误消息

I get the error with a full Application testing context

@RunWith(SpringRunner.class)
@SpringBootTest(
        webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT,
        classes = { TestingUserConfiguration.class, Application.class }
)

以及单个DataSource配置和服务

As well as just the single DataSource config and Service

@RunWith(SpringRunner.class)
@SpringBootTest(classes = {
        MyDbConfig.class,
        MyService.class
})

oracle.jdbc.pool.OracleDataSource和oracle.jdbc.replay.OracleConnectionPoolDataSourceImpl都有错误. UCP没有影响.

Both oracle.jdbc.pool.OracleDataSource and oracle.jdbc.replay.OracleConnectionPoolDataSourceImpl have the error. UCP makes no difference.

OracleConnectionPoolDataSourceImpl具有不同的错误:

java.sql.SQLException:不支持的功能

java.sql.SQLException: Unsupported feature

尝试从OJDBC 12.2升级到2018.3，没有区别.

Tried upgrading from OJDBC 12.2 to 2018.3, no difference.

有人以前见过此错误吗? 关于为什么只在Spring单元测试中出现的任何想法?

Has anyone seen this error before? Any ideas on why it only appears with Spring unit tests?

推荐答案

经过一番摸索，我发现可以在测试套件中做到这一点:

After much head scratching, I found that doing this in the test suite:

static {
 ClassLoader.getSystemClassLoader().setPackageAssertionStatus("oracle.jdbc.driver", false);  
}

解决了我的问题，我确定这是oracle.jdbc.driver.T4CTTIfun类中的错误

Solved My issue, I am sure this is a bug in the oracle.jdbc.driver.T4CTTIfun class
