Question

我需要堆上缓存，所以我尝试使用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＆＃34;没有为类型＆＃34找到序列化器;警告？据我所知，无堆层不需要它。（见路易斯的Jacomet回复here）

Answer 1

降低日志级别 - 这是在DEBUG打印的，因此从技术上讲它不是警告。

确实你的堆上缓存可以正常工作。

EhCache，堆上层：未找到序列化程序
