JdbcTemplate queryForInt () est obsolète
Mise à niveau de la version Spring et remarqué quequeryForInt() est obsolète, que faut-il remplacer par?
private boolean isUserExists(String username) {
String sql = "SELECT count(*) FROM USERS WHERE username = ?";
boolean result = false;
//The method queryForInt(String, Object...) from the type JdbcTemplate is deprecated
int count = getJdbcTemplate().queryForInt(sql, new Object[] { username });
if (count > 0) {
result = true;
}
return result;
}
Solution
LesqueryForInt() etqueryForLong() sont obsolètes depuis la version 3.2.2 (corrigez-moi en cas d'erreur). Pour résoudre ce problème, remplacez le code parqueryForObject(String, Class).
private boolean isUserExists(String username) {
String sql = "SELECT count(*) FROM USERS WHERE username = ?";
boolean result = false;
int count = getJdbcTemplate().queryForObject(
sql, new Object[] { username }, Integer.class);
if (count > 0) {
result = true;
}
return result;
}
