アップデート ：
私の最初のコード：
Session session = getSessionfactory().openSession();
session.beginTransaction();
ArrayList<Object[]> results = null;
try {
StringBuilder sb = new StringBuilder();
sb.append("select p from person p ");
sb.append("where CONTAINS(p.name , :myName) ");
Query q = session.createSQLQuery(sb.toString());
String myName = "Bob Jones";
q.setString("myName", "*" + myName + "*");
results = (ArrayList<Object[]>) q.list();
} catch (Exception e) {
logger.error("Error : ", e);
} finally {
session.close();
}
それは動作しません、それを修正するために これは2番目のバージョンです：
Session session = getSessionfactory().openSession();
session.beginTransaction();
ArrayList<Object[]> results = null;
try {
StringBuilder sb = new StringBuilder();
sb.append("select p from person p ");
sb.append("where CONTAINS(p.name , :myName) ");
Query q = session.createSQLQuery(sb.toString());
String myName = "Bob Jones";
q.setString("myName", "\"*" + myName + "*\"");
results = (ArrayList<Object[]>) q.list();
} catch (Exception e) {
logger.error("Error : ", e);
} finally {
session.close();
}
2番目のバージョンを実行しようとすると、上記のエラーが発生します。
