Java如何将Geometry数据写入到mysql5.7

可以使用JDBC连接mysql5.7，然后使用PreparedStatement对象将Geometry数据写入到mysql5.7，具体步骤如下：

1. 加载JDBC驱动程序：Class.forName("com.mysql.jdbc.Driver");

2. 连接mysql5.7数据库：Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/test", "root", "password");

3. 创建PreparedStatement对象：PreparedStatement ps = conn.prepareStatement("insert into table_name (geometry_column) values (?)");

4. 将Geometry数据转换成byte数组：byte[] geometryBytes = geometry.toBinary();

5. 将Geometry数据设置到PreparedStatement对象中：ps.setBytes(1, geometryBytes);

6. 执行插入操作：ps.executeUpdate();

完整代码示例：

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.SQLException;

import com.vividsolutions.jts.geom.Geometry;

public class GeometryToMysql {

    public static void main(String[] args) {
        String url = "jdbc:mysql://localhost:3306/test";
        String user = "root";
        String password = "password";

        try {
            Class.forName("com.mysql.jdbc.Driver");
            Connection conn = DriverManager.getConnection(url, user, password);

            String sql = "insert into table_name (geometry_column) values (?)";
            PreparedStatement ps = conn.prepareStatement(sql);

            // 将Geometry数据转换成byte数组
            Geometry geometry = ...;
            byte[] geometryBytes = geometry.toBinary();

            // 将Geometry数据设置到PreparedStatement对象中
            ps.setBytes(1, geometryBytes);

            // 执行插入操作
            ps.executeUpdate();

            ps.close();
            conn.close();
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }

}
