Spring Boot测试中无法屏蔽Spring Test Context相关日志的问题求助

我有一批放在com.company.integration包下的集成测试，现在想减少输出的日志量，特别是要屏蔽下面这类日志：

17:41:31.875 [main] DEBUG org.springframework.test.context.BootstrapUtils - Instantiating CacheAwareContextLoaderDelegate from class [org.springframework.test.context.cache.DefaultCacheAwareContextLoaderDelegate]
17:41:31.879 [main] DEBUG org.springframework.test.context.BootstrapUtils - Instantiating BootstrapContext using constructor [public org.springframework.test.context.support.DefaultBootstrapContext(java.lang.Class,org.springframework.test.context.CacheAwareContextLoaderDelegate)]
17:41:31.887 [main] DEBUG org.springframework.test.context.BootstrapUtils - Instantiating TestContextBootstrapper for test class [com.company.integration.EndpointControllerTest] from class [org.springframework.boot.test.context.SpringBootTestContextBootstrapper]
17:41:31.891 [main] INFO org.springframework.boot.test.context.SpringBootTestContextBootstrapper - Neither @ContextConfiguration nor @ContextHierarchy found for test class [com.company.integration.EndpointControllerTest], using SpringBootContextLoader

我已经尝试过的方法 #

• 在各个测试类（包括所有测试类继承的、带有@SpringBootTest注解的父类）上添加如下注解：

@TestPropertySource(properties = {
    "logging.level.org.springframework.test.context=ERROR",
    "logging.level.org.springframework.test.context.cache=ERROR",
    "logging.level.org.springframework.boot.test.context=ERROR",
    "logging.level.root=ERROR"
})

• 在@SpringBootTest注解中直接配置属性：

@SpringBootTest(properties = {
    "logging.level.org.springframework.test.context=ERROR",
    "logging.level.org.springframework.test.context.cache=ERROR",
    "logging.level.org.springframework.boot.test.context=ERROR",
    "logging.level.root=ERROR"
})

• 在test-application.properties配置文件以及主应用的application.properties中添加配置：

logging.level.root=ERROR
logging.level.org.springframework.test.context=ERROR
logging.level.org.springframework.boot.test.context=ERROR
logging.level.org.springframework.context=ERROR
logging.level.org.springframework=ERROR

但以上方法都没能屏蔽掉目标日志，我是不是漏掉了什么？有没有办法能成功屏蔽这些日志？
