java查询指定数据库的表名

//获取数据表名
    public List getDataTableName(String database) {
        Connection connection = getConnection();
        List list = new ArrayList<>();
        try {
            DatabaseMetaData databaseMetaData = connection.getMetaData();
            ResultSet resultSet = databaseMetaData.getTables(database,"root","%",new String[]{"TABLE"});
            while (resultSet.next()){
                list.add(resultSet.getString("TABLE_NAME"));
            }
            resultSet.close();
        } catch (SQLException e) {
            e.printStackTrace();
        }
        return list;
    }

参考文章：

MySql 查询数据库中所有表名 

查询避免Unknown column ‘xxx’ in ‘where clause’

ResultSet getTables(String catalog,
                    String schemaPattern,
                    String tableNamePattern,
                    String[] types)
                    throws SQLException

catalog指的是数据库
schemaPattern是数据库的用户
tableNamePattern是表名
types指的是table、view等
