PostgreSQL、JAP、Springboot保存Point空间数据

使用springboot Jpa保存Point类型坐标到PostgreSQL。

application.properties文件配置

spring.datasource.url=jdbc:postgresql://127.0.0.1:5432/geoserver
spring.datasource.username=test
spring.datasource.password=test
spring.jpa.database=postgresql
spring.jpa.hibernate.ddl-auto=update
spring.jpa.properties.hibernate.dialect=org.hibernate.spatial.dialect.postgis.PostgisDialect
spring.jpa.properties.hibernate.temp.use_jdbc_metadata_defaults=false
spring.jpa.show-sql=true

pom.xml文件配置
