我在方法中使用Spring's @Cacheable，并使用Ehcache作为实现，方法和缓存在被调用时都可以正常工作，但是在放入缓存结果时，第三个调用被阻塞。
我调试了代码，发现它在这里阻塞了：
org.ehcache.impl.internal.concurrent.ConcurrentHashMap.transfer(ConcurrentHashMap.Node<K, V>[] tab, ConcurrentHashMap.Node<K, V>[] nextTab)
存在无限循环
我的代码就像
...
@Autowired
private BService bService;
...
@Cacheable(cacheManager = "ehcacheManager", value = "cache_10s", key = "'a_' + #appKey'", sync = true)
public List<xxx> methodA(String appKey) {
return bService.methodB(convertFrom(appKey));
}
...
...
@Cacheable(cacheManager = "ehcacheManager", value = "cache_10s", key = "'b_' + #parameterId", sync = true)
public List<xxx> bMethod(Long parameterId) {
//block after return
return parameterId;
}
...
@Configuration
public class EhcacheConfiguration {
@Bean
public JCacheManagerFactoryBean jCacheManagerFactoryBean() throws IOException {
JCacheManagerFactoryBean jCacheManagerFactoryBean = new JCacheManagerFactoryBean();
jCacheManagerFactoryBean.setCacheManagerUri(new ClassPathResource("ehcache.xml").getURI());
return jCacheManagerFactoryBean;
}
@Bean(name = "ehcacheManager")
public JCacheCacheManager jCacheCacheManager(@Qualifier("jCacheManagerFactoryBean") CacheManager jCacheManagerFactoryBean) {
JCacheCacheManager jCacheCacheManager = new JCacheCacheManager();
jCacheCacheManager.setCacheManager(jCacheManagerFactoryBean);
return jCacheCacheManager;
}
}
