我正在使用JDBC和H2数据库开发应用程序,有时需要删除数据库文件。有没有办法做到这一点?

是的,你可以!
请参阅此答案,找到H2存储数据库的文件夹(通常是用户的主目录): Where does H2's Embedded Databases Store the data?
要删除它,可以使用org.h2.tools.DeleteDbFiles类,如下所示:
DeleteDbFiles.execute(dbDir, dbName, true);

private static async Task<string> ProcessResponseAsync(HttpResponseMessage response)
{
var responseText = await response.Content.ReadAsStringAsync().ConfigureAwait(false);

private static string GetUrl(string area, string method, string parameters)
{
if (!string.IsNullOrEmpty(parameters))
{
if (parameters[0] != '?')
{
parameters = $"?{parameters}";
}
}
var address = ConfigurationManager.AppSettings["GatewayUrl"];
var result = $"{address}/{area}/{method}{parameters}";
return result;
}
protected async Task<string> ExecuteRequestAsync(string area, string method, string parameters)
{
var url = GetUrl(area, method, parameters);
var response = await _httpClient.GetAsync(url).ConfigureAwait(false);
var result = await ProcessResponseAsync(response).ConfigureAwait(false);
return result;
