要获取所有表名,可以使用MyBatis的Mapper接口和对应的XML配置文件来实现。以下是一个简单的示例代码:
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);
}
以上代码示例中,使用MyBatis的Mapper接口和XML配置文件来获取数据库中所有表名,通过执行相应的SQL语句来查询表名并返回到Java程序中。
