这是一个 beanshell 代码，因此对于 Java 开发人员来说，有些事情可能看起来很奇怪。emailFileAttachment 函数是一个saipoint API，我正在使用的一个工具。我的问题是我放在地图中的数据被放在 excel 文件中的一行中。我放入地图的标题（“Application, Num_entitlement”）没有打印在 CSV 文件的第一行。谁能帮帮我。这是我下面的代码：

String query = "SELECT app.name as application, count(*) as num_entitlements FROM spt_application as app, spt_identity_entitlement as ent WHERE app.id = ent.application GROUP BY app.name";
HashMap info = new HashMap();
info.put("Application ", "Num_Entitlement");
PreparedStatement getEntitlement_Num = null;
Connection conn = null;

fileInputStream.close();
}

{
e.printStackTrace();
}
return byteFile;
}
*/
try{
// Prepared Statements
Environment e = Environment.getEnvironment();
DataSource src = e.getSpringDataSource();
//System.out.println("DataSource: " + src.toString());
conn = src.getConnection();
//System.out.println("Connection: " + conn);
getEntitlement_Num = conn.prepareStatement(query);
ResultSet rs = getEntitlement_Num.executeQuery();
//System.out.println("starting RS");
while(rs.next()) {
String appName = rs.getString("application");
int no_ent = rs.getInt("num_entitlements");
info.put(appName , no_ent);
}
System.out.println("finished RS");
}catch(SQLException e){
log.error( e.toString());
} finally {
if (getEntitlement_Num!= null) {
getEntitlement_Num.close();
}
if(conn != null) {
conn.close();
}
}
//I am using sailpoint APIs for the code below.
String emailDest = "//email address here";
EmailTemplate et = new EmailTemplate();
et.setFrom("//email address here");
et.setBody("Please find an attached CSV file that has the list of all applications in IIQ and their number of Entitlements");
et.setTo(emailDest);
et.setSubject("Entitlement count for each application in IIQ");
EmailOptions ops = new EmailOptions(emailDest,null);
String strInfo = Util.mapToString(info);
byte[] fileData = strInfo.getBytes();
EmailFileAttachment attachment = new EmailFileAttachment( "EntitlementCount.csv", EmailFileAttachment.MimeType.MIME_CSV, fileData );
ops.addAttachment(attachment);
context.sendEmailNotification(et, ops);
//System.out.println("email sent");
return "Success";
