示例1: resolveEntity

import com.sun.org.apache.xerces.internal.xni.XMLResourceIdentifier; //导入方法依赖的package包/类
/**
 * Resolves the specified public and system identifiers. This
 * method first attempts to resolve the entity based on the
 * EntityResolver registered by the application. If no entity
 * resolver is registered or if the registered entity handler
 * is unable to resolve the entity, then default entity
 * resolution will occur.
 *
 * @param publicId     The public identifier of the entity.
 * @param systemId     The system identifier of the entity.
 * @param baseSystemId The base system identifier of the entity.
 *                     This is the system identifier of the current
 *                     entity and is used to expand the system
 *                     identifier when the system identifier is a
 *                     relative URI.
 *
 * @return Returns an input source that wraps the resolved entity.
 *         This method will never return null.
 *
 * @throws IOException  Thrown on i/o error.
 * @throws XNIException Thrown by entity resolver to signal an error.
