This a convenience class that just extends JDBC2DataStore to keep current datastores that use it happy. Eventually datastores should extend one of JDBC1DataStore, or JDBC2DataStore. <p> This class provides a default implementation of a JDBC data store. Support for vendor specific JDBC data stores can be easily added to Geotools by subclassing this class and overriding the hooks provided. </p> <p> At a minimum subclasses should implement the following methods: <ul> <li> <A HREF="../../../../org/geotools/data/jdbc/JDBC1DataStore.html#buildAttributeType(java.sql.ResultSet)"><CODE>buildAttributeType(ResultSet)</CODE></A> - This should be overriden to construct an attribute type that represents any column types not supported by the default implementation, such as geometry columns. </li> <li> <A HREF="../../../../org/geotools/data/jdbc/JDBC1DataStore.html#getGeometryAttributeIO(org.geotools.feature.AttributeType, org.geotools.data.jdbc.QueryData)"><CODE>getGeometryAttributeIO(AttributeType, QueryData)</CODE></A> - Should be overriden to provide a way to read/write geometries into the format of the database </li> </ul> </p> <p> Additionally subclasses can optionally override the following: <ul> <li> Use a specific FIDMapperFactory by overriding the <A HREF="../../../../org/geotools/data/jdbc/JDBC1DataStore.html#buildFIDMapperFactory(org.geotools.data.jdbc.JDBCDataStoreConfig)"><CODE>buildFIDMapperFactory(JDBCDataStoreConfig)</CODE></A> method, and eventually disallow user overrides by throwing an <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/UnsupportedOperationException.html" title="class or interface in java.lang"><CODE>UnsupportedOperationException</CODE></A> in the <A HREF="../../../../org/geotools/data/jdbc/JDBC1DataStore.html#setFIDMapperFactory(org.geotools.data.jdbc.fidmapper.FIDMapperFactory)"><CODE>setFidMapperFactory()</CODE></A> method. </li> <li> <A HREF="../../../../org/geotools/data/jdbc/JDBC1DataStore.html#allowTable(java.lang.String)"><CODE>allowTable</CODE></A> - Used to determine whether a table name should be exposed as a feature type. </li> <li> <A HREF="../../../../org/geotools/data/jdbc/JDBC1DataStore.html#determineSRID(java.lang.String, java.lang.String)"><CODE>determineSRID</CODE></A> - Used to determine the SpatialReference ID of a geometry column in a table. </li> <li> <CODE>buildSQLQuery()</CODE> - Sub classes can override this to build a custom SQL query. </li> <li> <A HREF="../../../../org/geotools/data/jdbc/JDBC1DataStore.html#getResultSetType(boolean)"><CODE>getResultSetType</CODE></A> if the standard result set type is not satisfactory/does not work with a normal FORWARD_ONLY resultset type </li> <li> <A HREF="../../../../org/geotools/data/jdbc/JDBC1DataStore.html#getConcurrency(boolean)"><CODE>getConcurrency</CODE></A> to set the level of concurrency for the result set used to read/write the database </li> </ul> </p> <p> Additionally subclasses may want to set the value of: <ul> <li> sqlNameEscape - character (String) to surround names of SQL objects to support mixed-case and non-English names. </li> </ul> </p><P><P>⌨️ 快捷键说明
