做子图层控制时,导致操作不流畅,并且操作一次显示的图层时不会即使刷新图层,需要放大缩小地图才会重新渲染
The configured limit of 1,000 object references was reached while attempting to calculate the size of the object graph. Severe performance degradation could occur if the sizing operation continues. This can be avoided by setting the CacheManger or Cache <sizeOfPolicy> elements maxDepthExceededBehavior to "abort" or adding stop points with @IgnoreSizeOf annotations. If performance degradation is NOT an issue at the configured limit, raise the limit value using the CacheManager or Cache <sizeOfPolicy> elements maxDepth attribute. For more information, see the Ehcache configuration documentation.
