ibatis缓存强制刷新与命中率

缓存强制刷新：

// spring注入
 private SqlMapClient sqlMapClient;

 public SqlMapClient getSqlMapClient() {
  return sqlMapClient;
 }

 public void setSqlMapClient(SqlMapClient sqlMapClient) {
  this.sqlMapClient = sqlMapClient;
 }

 public ActionForward unspecified(ActionMapping mapping, ActionForm form, HttpServletRequest request,
   HttpServletResponse response) throws Exception {
  String[] cacheModelIds = new String[] { "TBL_SELL.oneDayCache" };

  // 刷新指定缓存
  if (cacheModelIds.length > 0) {
   for (String cacheModelId : cacheModelIds) {
    sqlMapClient.flushDataCache(cacheModelId);
   }
  } else {
   // 刷新所有缓存
   sqlMapClient.flushDataCache();
  }
  return null;
 }

 

命中率输出：

SqlMapClientImpl impl = (SqlMapClientImpl) sqlMap;

SqlMapExecutorDelegate delegate = impl.delegate;

Iterator cacheModelNames = delegate.getCacheModelNames();

while(cacheModelNames.hasNext()){

        String model = (String) cacheModelNames.next();

        CacheModel cacheModel = delegate.getCacheModel(model);

        System.out.println(model + ": " + cacheModel.getHitRatio() + "% hit ratio");

}

 

 

spring 导致缓存 失效
