Java项目警告

Question

启动glassfish服务器后，我会收到以下警告：

Warning:   Class 'javax.ejb.PostActivate' not found, interception based on it is not enabled
Warning:   Class 'javax.ejb.PrePassivate' not found, interception based on it is not enabled

这种警告的原因是什么？我怎么才能摆脱他们？

UPD1。

在构建应用程序时，NetBeans似乎正在将一堆jars放入应用程序的WEB/lib目录中。这些jars不应该放在WEB/lib中。

所以可能是这样的，因为有些jars不应该放在WEB/lib中，这是我所拥有的：

​

​

UPD2。

如果您使用Netbeans 7.4并使用"new应用程序“向导，只需单击默认值，只需选中复选框以包含”上下文和依赖项注入“，然后在GlassFish 4上运行它，您将得到警告。

:(

UPD3。有人在这里说应忽略以下警告消息，它们是“假阳性”警报消息。

UPD4。是的，我在用maven。这是我的pom.xml

Answer 1

原因是:找不到类javax.ejb.PostActivate和javax.ejb.PrePassivate。你失去了依赖。

将此依赖项添加到pom.xml中：

<dependency>
    <groupId>javax.ejb</groupId>
    <artifactId>javax.ejb-api</artifactId>
    <version>3.2</version>
</dependency>
