SpringBoot操作前端传的Geojson进行空间查询

SpringBoot操作前端传的Geojson进行空间查询

项目说明:

项目技术栈:SpringBoot+MybatisPlus+postgresql

先上查询SQL

SELECT *
FROM demo
WHERE ST_Intersects(geom, ST_GeomFromGeoJSON('放geojson类型数据'));

表结构

Controller层

package com.itcy.postgresql.controller;


import com.itcy.postgresql.model.Demo;
import com.itcy.postgresql.service.DemoService;
import org.locationtech.jts.geom.Geometry;
import org.springframework.beans.factory.annotation.Autowired;


import java.util.List;

 */
@RestController
@RequestMapping("/demo")
public class DemoController {

    @Autowired
    private DemoService demoService;


    /**
     * 传入geojson数据类型查询相交情况*/
    @PostMapping("/getByGeoJson")
    public List<Demo> getByGeoJson(@RequestBody String geoJson){
        return demoService.getByGeoJson(geoJson);
    }

Service层

package com.itcy.postgresql.service;


import com.itcy.postgresql.model.Demo;
import org.locationtech.jts.geom.Geometry;
import java.util.List;

/**
 * @author 176
 */
public interface DemoService {

    /**
     * 传入geojson数据类型查询相交情况*/
    List<Demo> getByGeoJson(String geoJson);
}

ServiceImpl层

package com.itcy.postgresql.service.impl;

import com.itcy.postgresql.mapper.DemoMapper;
import com.itcy.postgresql.model.Demo;
import com.itcy.postgresql.service.DemoService;
import org.locationtech.jts.geom.Geometry;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

/**
 * @author 176
 */
@Service
public class DemoServiceImpl implements DemoService {

    
    @Override
    public List<Demo> getByGeoJson(String geoJson) {
        return demoMapper.getByGeoJson(geoJson);
    }
}

Mapper层

package com.itcy.postgresql.mapper;

import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import com.itcy.postgresql.model.Demo;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Param;
import org.apache.ibatis.annotations.Select;
import org.locationtech.jts.geom.Geometry;

import java.util.List;

@Mapper
public interface DemoMapper extends BaseMapper<China> {
    List<Demo> getByGeoJson(String geoJson);
}
