java输入姓名查询MySQL中的相关某一行信息

好的，您可以使用以下代码实现：

import java.sql.*;

public class QueryData {
    public static void main(String[] args) {
        String name = "your_name"; // 替换成您要查询的姓名
        Connection conn = null;
        Statement stmt = null;
        ResultSet rs = null;
        try {
            // 加载MySQL驱动
            Class.forName("com.mysql.cj.jdbc.Driver");
            // 建立连接
            String url = "jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf-8&serverTimezone=GMT%2B8&useSSL=false";
            String username = "root"; // 替换成您的MySQL用户名
            String password = "123456"; // 替换成您的MySQL密码
            conn = DriverManager.getConnection(url, username, password);
            // 执行查询语句
            stmt = conn.createStatement();
            String sql = "SELECT * FROM table_name WHERE name='" + name + "'";
            rs = stmt.executeQuery(sql);
            // 输出查询结果
            while (rs.next()) {
                String id = rs.getString("id");
                String age = rs.getString("age");
                String address = rs.getString("address");
                System.out.println("id:" + id + ", age:" + age + ", address:" + address);
            }
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            // 关闭资源
            try {
                if (rs != null) {
                    rs.close();
                }
                if (stmt != null) {
                    stmt.close();
                }
                if (conn != null) {
                    conn.close();
                }
            } catch (SQLException e) {
                e.printStackTrace();
            }
        }
    }
}

其中，`test`是数据库名，`table_name`是表名，`id`、`age`、`address`是列名，您需要根据实际情况进行修改。
