我有以下一段代码。当我传递像“firstname lastname”这样的普通字符串时。存储过程很快就会返回。但是当我用 firstname* 调用它时，它需要很多时间。当我使用 firstname* 执行存储过程时，不会超过 2 秒。这是下面的代码
public List<NameBean> getNameReportJson(final int numberOfResults,
final String searchValue, final String category, Connection con)
throws SQLException {
final List<NameBean> beanList = new ArrayList();
List<String> resultStrs = new ArrayList<String>();
final String nameReportStoreProcedure = "{call [sp_SENTRY_INFORMATION_REPORT_NAME_REPORT] (?,?,?,?,?)}";
Session session = (Session) em.getDelegate();
StringBuffer sb = new StringBuffer();
session.doWork(new Work() {
@Override
public void execute(Connection connection) throws SQLException {
CallableStatement cstmt = connection
.prepareCall(nameReportStoreProcedure);
ResultSet rs = null;
cstmt.setInt("numberOfResults", numberOfResults);
cstmt.setString("SearchValue", searchValue);
cstmt.setString("Category", category);
cstmt.setDate("startDate", null);
cstmt.setDate("endDate", null);
rs = cstmt.executeQuery();
logger.debug("CeReport the ResultSet is: " + rs);
while (rs.next()) {
NameBean nameBean = new NameBean();
String oriName = rs.getString("ORIGINAL NAME");
String standName = rs.getString("STANDARDIZED NAME");
String groupName = rs.getString("GROUP NAME");
long groupId = rs.getLong("GROUP ID");
nameBean.setOriginalName(oriName);
nameBean.setStandardName(standName);
nameBean.setGroupName(groupName);
nameBean.setGroupID(groupId);
nameBean.setEntityID(rs.getString("ENTITY ID"));
beanList.add(nameBean);
}
}
});
return beanList;
}
