java - Hibernate HQL 带有 Likes 的意外标记

Question

我的 Spring Web 模型- View - Controller (MVC) 框架中有这个类。 Spring Web 模型- View - Controller (MVC) 框架的版本是 3.2.8。

我在 1 个 DAO 中有这个方法

final StringBuilder queryString = new StringBuilder("  select app from Application app where upper (ticket_id) like :searchString and upper (id) like :searchString " );

        queryString.append("where  app.status != " + Status.READY.ordinal());

        queryString.append(" order by app.submissionTime desc ");

        try {

            final Query query = getEntityManager().createQuery(queryString.toString());

            searchString = searchString.replace("!", "!!")
                       .replace("%", "!%")
                       .replace("_", "!_")
                       .replace("[", "![")
                       .trim()
                       .toUpperCase();


            query.setParameter ("searchString", searchString);                      

            return query.getResultList();

但是我在运行时遇到此错误:

 org.   where near line 1, column 144 [  select app from com.tdk.devices.domain.Application app where upper (ticket_id) like :searchString and upper (id) like :searchString where  app.status != 0 order by app.submissionTime desc ]

您使用了“where”子句 2 次。首先在StringBuilder的构造函数中，然后:

queryString.append("where  app.status != " + Status.READY.ordinal());
