java 数据库生成json文件 java生成sql文件

实例代码：

package com.db;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;

public class Sqlitemain {

	public static void main(String[] args) {
		// load the sqlite-JDBC driver using the current class loader
//		Class.forName("org.sqlite.JDBC");

		Connection connection = null;
		try {
			// create a database connection
			connection = DriverManager.getConnection("jdbc:sqlite:D:/people1.db");
			Statement statement = connection.createStatement();
			statement.setQueryTimeout(30); // set timeout to 30 sec.

			statement.executeUpdate("drop table if exists person");
			statement.executeUpdate("create table person (id integer, name string)");
			statement.executeUpdate("insert into person values(1, 'leo')");
			statement.executeUpdate("insert into person values(2, 'yui')");
			ResultSet rs = statement.executeQuery("select * from person");
			while (rs.next()) {
				// read the result set
				System.out.println("name = " + rs.getString("name"));
				System.out.println("id = " + rs.getInt("id"));
			}
		} catch (SQLException e) {
			// if the error message is "out of memory",
			// it probably means no database file is found
			System.err.println(e.getMessage());
		} finally {
			try {
				if (connection != null)
					connection.close();
			} catch (SQLException e) {
				// connection close failed.
				System.err.println(e);
			}
		}
	}
}

结果：

name = leo
id = 1
name = yui
id = 2
