【问题描述】：
我对 JPQL 有疑问...我正在尝试使用 Vaadin、Shiro、MySQL、JPA 制作一个 Web 应用程序...几年前我制作了一个桌面应用程序，并从中使用了 JPA 的所有库项目。我对 mysql-connector-java-5.0.8-bin.jar 有疑问。当我尝试运行该项目时，我变成了一个 SQL 异常 com.mysql.jdbc.driver not found。很少有人遇到同样的问题，并通过将 mysql 连接器 5.0.8 替换为 5.1.17 或更高版本来解决它。我做了这个，现在我遇到了一个新的查询问题。
这个查询工作正常：
TypedQuery<Products> q = em.createQuery("SELECT e FROM Products e",Products.class);
List<Products> products = q.getResultList();
这个查询不能正常工作：
TypedQuery<Products> q = em.createQuery("SELECT e FROM Products e WHERE e.name LIKE 'something'",Products.class);
Products products = q.getSingleResult();
我变成了这个例外：

谢谢...
编辑 1 我已经测试了另一个查询，它也很好......
TypedQuery<Products> query1 = em.createQuery("SELECT e FROM Products e WHERE e.name LIKE 'something' OR e.name LIKE 'somethingElse' ",Products.class);
List<Products> list = query1.getResultList();
Where 语句不是问题。问题是getSingleResult，但我不知道如何解决它...... 谢谢...

您的意思是当您不在 LIKE 和表达式之间添加空格时？令人惊讶吗？
-
不，就在我使用 query.getSingleResult() 方法时...我使用 query.getResultList() 运行相同的查询，它工作正常...

你必须在 LIKE 和参数之间有一个空格。如果您在失败的 JPQL 中确实有空格，那么我强烈建议您修复您的帖子以表明这一点
