我有一个spring boot rest项目，其中包含多个@springboottest junit测试用例。
该项目使用带cache2k的spring缓存。有一个工厂bean，它创建了一个带有缓存的cachemanager。

@Bean
public CacheManager cache2kCacheManager() {
    SpringCache2kCacheManager cache2kCacheManager = new SpringCache2kCacheManager()
            .defaultSetup(b -> b.entryCapacity(3).expireAfterWrite(3, TimeUnit.SECONDS).disableMonitoring(false));
    Function<Cache2kBuilder<?, ?>, Cache2kBuilder<?, ?>> campaignCacheBuilder;
    campaignCacheBuilder = x -> x.name("campaigns-cache")
            .entryCapacity(5));
    cache2kCacheManager.addCaches(campaignCacheBuilder);
    return cache2kCacheManager;
}

在ide中运行时，所有测试用例都成功运行。应用程序在ide中启动时也会运行。但是当我跑的时候 mvn clean install 在项目中，由于缓存对象创建错误，测试用例失败。

[ERROR] testCacheReadAndWrite  Time elapsed: 0 s  <<< ERROR!
java.lang.IllegalStateException: Failed to load ApplicationContext
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'cache2kCacheManager' defined in class path resource [com/demos/cachedemo/cache/configuration/Cache2KConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.cache.CacheManager]: Factory method 'cache2kCacheManager' threw exception; nested exception is java.lang.IllegalStateException: Cache already created: 'campaigns-cache'

我尝试删除错误的测试用例，但其他测试用例开始失败，出现相同的异常。似乎上下文正在被重用/共享。我已经在测试用例中添加了@dirtiescontext，但这并不能解决这个问题。
有人能帮我解决这个问题吗？
更新1:该项目是使用start.spring.io创建的，在pom.xml中有默认的构建插件。
