我需要堆上缓存,因此我正在尝试使用ehcache v3.5.2
我有下一个测试:
public class TestEhCache {
public static class MyObj {
String message;
public MyObj(String message) {
this.message = message;
}
}
@Test
public void testDebugLogs() {
CacheManager cacheManager;
cacheManager = CacheManagerBuilder.newCacheManagerBuilder().build();
cacheManager.init();
Cache<String, MyObj> myCache = cacheManager.createCache("myCache",
CacheConfigurationBuilder.newCacheConfigurationBuilder(String.class, MyObj.class, ResourcePoolsBuilder.heap(3))
.build());
}
}
结果,我看到了下一个警告

如何抑制“未找到类型的序列化程序”警告?据我了解,无堆层不是必需的。 (请参阅路易斯的Jacomet答复here)
最佳答案
降低日志级别-打印在DEBUG
上,因此从技术上讲不是警告。
确实,您的堆上缓存可以正常工作。
