java读取mysql的geometry
解决方法：
1.查数据的sal
加上ST_ASTEXT函数
SELECT ST_ASTEXT(e.geom) geom from tb_real_estate e
2.其中row.get("geom").toString()就是geometry字段的文本值
String wkt = row.get("geom").toString();
//WKT转Geometry
WKTReader wktReader = new WKTReader();
Geometry geometry = null;
try {
geometry = wktReader.read(wkt);
//geometry.setSRID(4326);
} catch (com.vividsolutions.jts.io.ParseException e) {
e.printStackTrace();
}
3.我的pom.xml依赖
