postgreSQL空间函数的简单使用

创建空间对象表：

create table t_point (  
   id            VARCHAR(36)          not null,
   name            VARCHAR(200)          null,
   lonlat               GEOMETRY             null,  
   createTime          TIMESTAMP            null,  
   constraint PK_T_POINT primary key (id)  
);  
office对象：
private Geometry lonlat;

获取经纬度：
Geometry officelatlon = office.getLonlat();
Point officeP = (Point)officelatlon;
double officeLon = officeP.getX();
double officeLat = officeP.getY();


插入空间点：
INSERT INTO geometry_data (name,addr,geom) VALUES (?,?,'POINT(116.3908 39.92549)')




2点之间的距离：
st_distance_sphere(ST_MakePoint("+lonlat+"),lonlat)  


查询点在面内：
SELECT id,name,addr,ST_AsText(ST_GeomFromText(geom)) FROM geometry_data WHERE 1=1 
AND name like '私%建%' AND addr like '%中%' AND ST_Within
(geom,ST_GeomFromText('POLYGON((116.38272 39.90706,116.38350614443412 39.95209818446651))')) 
LIMIT 10 OFFSET 0
