如何使用spring boot JPA在Postgres中存储Geometry Point？

Question

To store longitude and latitude as geometry location as Point in Postgres using spring boot jpa.

After applying below code it throws: column "location" is of type point but expression is of type bytea.

Also when fetching data it throws: could not deserialize; nested exception is org.hibernate.type.SerializationException: could not deserialize

Add dependency in pom.xml

<dependency>
    <groupId>com.vividsolutions</groupId>
    <artifactId>jts</artifactId>
    <version>1.13</version>
</dependency>
<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-spatial</artifactId>
    <version>5.4.1.Final</version>
</dependency>

Add column in entity class.

@Column(columnDefinition = "POINT")
private Point location;

For storing data into database

GeometryFactory geometryFactory = new GeometryFactory();

            Coordinate coordinate = new Coordinate();
            coordinate.x = 2;
            coordinate.y = 5;

            Point myPoint = geometryFactory.createPoint(coordinate);
            user.setLocation(myPoint);

I need to store data as (30.5,53.123) format in Postgres.
