java,java – 使用Point类型与PostgreSQL和JPA / Hibernate

有没有办法将Point列映射到

Java实体字段？

我尝试过Hibernate Spatial 4.0,但是似乎它并不适用于没有PostGIS的纯PostgreSQL.这里是点字段定义：

import com.vividsolutions.jts.geom.Point;

...

@Column(columnDefinition = "point")

@Type(type = "org.hibernate.spatial.GeometryType")

private Point location;

persistence.xml中的方言：

当我尝试保留这个实体时,抛出异常：

org.postgresql.util.PSQLException: Unknown type geometry.

at org.postgresql.jdbc2.AbstractJdbc2Statement.setPGobject(AbstractJdbc2Statement.java:1603)

at org.postgresql.jdbc2.AbstractJdbc2Statement.setObject(AbstractJdbc2Statement.java:1795)

at org.postgresql.jdbc3g.AbstractJdbc3gStatement.setObject(AbstractJdbc3gStatement.java:37)

at org.postgresql.jdbc4.AbstractJdbc4Statement.setObject(AbstractJdbc4Statement.java:46)

所以似乎它试图坚持几何类型PostGIS的价值.但是我只想使用简单的点.
