要獲取所有表名,可以使用MyBatis的Mapper接口和對(duì)應(yīng)的XML配置文件來(lái)實(shí)現(xiàn)。以下是一個(gè)簡(jiǎn)單的示例代碼:
public interface TableMapper {
List<String> getAllTableNames();
}
<!-- TableMapper.xml -->
<mapper namespace="com.example.mapper.TableMapper">
<select id="getAllTableNames" resultType="String">
SELECT table_name
FROM information_schema.tables
WHERE table_schema = 'your_database_name'
</select>
</mapper>
<!-- mybatis-config.xml -->
<configuration>
<mappers>
<mapper resource="com/example/mapper/TableMapper.xml"/>
</mappers>
</configuration>
SqlSession sqlSession = sqlSessionFactory.openSession();
TableMapper tableMapper = sqlSession.getMapper(TableMapper.class);
List<String> tableNames = tableMapper.getAllTableNames();
sqlSession.close();
for (String tableName : tableNames) {
System.out.println(tableName);
}
以上代碼示例中,使用MyBatis的Mapper接口和XML配置文件來(lái)獲取數(shù)據(jù)庫(kù)中所有表名,通過(guò)執(zhí)行相應(yīng)的SQL語(yǔ)句來(lái)查詢表名并返回到Java程序中。
