Spring+SpringMVC+hibernate spatial+oracle spatial 映射存储Geomety空间数据过程记录
本文仅用于记录自己在摸索oracle spatial存储地理数据的过程,以便哪天忘记了,重新回顾下,由于本人过懒直接上代码没写详细步骤,参考的朋友们若有对过程不理解的部分或者看不懂的地方还请见谅,或者可以私信我,当然若有指教的地方亦可以私信或者留言,不胜感激。

hibernate.cache.use_query_cache = true
hibernate.cache.region.factory_class = org.hibernate.cache.ehcache.EhCacheRegionFactory
hibernate.cache.provider_configuration_file_resource_path = ehcache.xml
hibernate这一块解释一下:因为存储的数据是地理数据,用到了oracle数据库中的oracle spatial,因此在配置hibernate时dialog用的是
org.hibernate.spatial.dialect.oracle.OracleSpatial10gDialect
另外还需要增加两个配置:
hibernate.spatial.connection_finder=com.hz.util.C3P0ConnectionFinder
hibernate.spatial.ogc_strict=true
同样一定要记得在hibernate.xml中添加以上三个配置。
com.hz.util.C3P0ConnectionFinder
这个类需要自己定义,代码如下:
public class C3P0ConnectionFinder implements ConnectionFinder {
public Connection find(Connection con) throws FinderException {
// TODO Auto-generated method stub
if (con == null) {
return null;
}
if (con instanceof C3P0ProxyConnection){
try {
C3P0NativeJdbcExtractor c3P0NativeJdbcExtractor = new C3P0NativeJdbcExtractor();
OracleConnection oracleConnection = (OracleConnection) c3P0NativeJdbcExtractor.getNativeConnection(con);
return oracleConnection;
} catch (Exception e) {
e.printStackTrace();
}
}
throw new FinderException(
"Couldn't get at the OracleSpatial Connection object from the PreparedStatement.");
}
}
测试类:
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"classpath:spring.xml","classpath:hibernate.xml"})
public class Poly_PolygonServiceTest {
private static final Logger LOGGER=Logger.getLogger(AdminUserServiceTest.class);
@Autowired
private Poly_PolygonService poly_polygonService;
@Test
public void save() throws ParseException{
Poly_Polygon polygon=new Poly_Polygon();
polygon.setUserid(7);
polygon.setAttributeTag("测试");
polygon.setCreateTime(new Date());
String wktGeom="POLYGON((1 1,5 1,5 5,1 5,1 1),(2 2,2 3,3 3,3 2,2 2))";
Wkt_Util fromText = new Wkt_Util();
Polygon poly=fromText.createPolygon(wktGeom);
polygon.setGeom(poly);
polygon.setId(9);
polygon.setPoints("999,222;888,777");
polygon.setPolyType("面");
polygon.setTrustValue(0.666);
polygon.setUserName("hz");
Integer userid= poly_polygonService.save(polygon);
List<Poly_Polygon>polygons =poly_polygonService.findAll();
for(int i=0;i<polygons.size();i++){
System.out.println(polygons.get(i).getUserName()+", Userid: "+polygons.get(i).getUserid());
}
LOGGER.info(JSON.toJSONString(userid));
}
}
当然也涉及到一个WKT转换工具类:
public class Wkt_Util {
private static GeometryFactory geometryFactory = new GeometryFactory();;
public static Polygon createPolygon(String polygonWKT) throws ParseException
{
WKTReader fromText = new WKTReader();
Geometry geom = null;
try {
geom = fromText.read(polygonWKT);
} catch (ParseException e) {
throw new RuntimeException("Not a WKT string:" + polygonWKT);
}
if (!geom.getGeometryType().equals("Polygon")) {
throw new RuntimeException("Geometry must be a Polygon. Got a " + geom.getGeometryType());
}
Polygon polygon=(Polygon)geom;
return polygon;
}
}
大致过程就是如此了。
