java显示数据库表_使用Java显示MySQL数据库中的所有表？

我们将在这里看到如何使用Java显示MySQL数据库中的所有表。您可以从MySQL使用show命令来获取MySQL数据库中的所有表。

假设我们的数据库为“测试”。Java代码如下所示&＃xff0c;以显示数据库“ test”中的所有表名。

Java代码如下。在这里&＃xff0c;MySQL和Java之间建立了连接-import java.sql.DriverManager;

import java.sql.ResultSet;

import java.sql.SQLException;

import com.mysql.jdbc.Connection;

import com.mysql.jdbc.DatabaseMetaData;

public class GetAllTables {

public static void main(String[] args) throws SQLException {

Connection conn &＃61; null;

try {

try {

Class.forName("com.mysql.jdbc.Driver");

} catch (Exception e) {

System.out.println(e);

}

conn &＃61; (Connection) DriverManager.getConnection("jdbc:mysql://localhost/test", "Manish", "123456");

System.out.println("成功创建连接&＃xff1a;");

} catch (Exception e) {

System.out.println(e);

}

ResultSet rs &＃61; null;

DatabaseMetaData meta &＃61; (DatabaseMetaData) conn.getMetaData();

rs &＃61; meta.getTables(null, null, null, new String[] {

"TABLE"

});

int count &＃61; 0;

System.out.println("所有表名都在测试数据库中&＃xff1a;");

while (rs.next()) {

String tblName &＃61; rs.getString("TABLE_NAME");

System.out.println(tblName);

count&＃43;&＃43;;

}

System.out.println(count &＃43; " Rows in set ");

}

}

以下是显示数据库测试中所有表的输出-Wed Dec 12 14:55:28 IST 2018 WARN: Establishing SSL connection without server&＃39;s identity verification is not recommended. According to MySQL 5.5.45&＃43;, 5.6.26&＃43; and 5.7.6&＃43; requirements SSL connection must be established by default if explicit option isn&＃39;t set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to &＃39;false&＃39;. You need either to explicitly disable SSL by setting useSSL &＃61; false, or set useSSL &＃61; true and provide truststore for server certificate verification.

要进行交叉检查&＃xff0c;请使用MySQL show命令显示数据库“ test”中的所有表。查询如下-mysql> use test;

Database changed

mysql> show tables;
