Question

我有一个应用程序（使用注释的Spring 4 MVC + Hibernate 4 + MySQL + Maven集成示例），使用基于注释的配置将Spring与Hibernate集成。

我在JSP中有这个问题

java.lang.RuntimeException：由于反射错误，表达式[$ {userItem.deviceBody.key}]的评估失败。

但在我的Junit测试中一切都很好：

这里有完整的错误：

for (User user : deviceBodies) {
    assertNotNull (user.getDeviceBody());
    assertNotNull (user.getDeviceBody().getKey());
}
