Jersey 2 替代 ServletContextListener
Jersey 2 alternative to ServletContextListener
我正在尝试在我的 Jersey 2 网络应用程序启动时初始化 StanfordCoreNLP。
我发现,ServletContextListener 是实现它的方法,但我在 jersey 2 中没有 ServletContextListener,对吗?
那么我如何在我的 jersey 2 webapp 启动时加载此代码:
Properties props = new Properties();
props.setProperty("annotators", "tokenize, ssplit, pos, lemma, ner, parse, dcoref");
StanfordCoreNLP pipeline = new StanfordCoreNLP(props);

}
}
ServletContextListener
如果是 Servlet API 的一部分。所以你可以添加
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.1.0</version>
<scope>provided</scope>
</dependency>
但这可能没有必要。除了 web.xml 之外,还有更多部署 Jersey 应用程序的方法。你可以扩展一个ResourceConfig
。这将允许您完全 xml-less 即使您愿意。您在 web.xml 中配置的所有内容,大部分都可以在 ResourceConfig
中配置。
您甚至可以同时使用 web.xml 和 和 ResourceConfig
。例如
public class MyApplication extends ResourceConfig {
public MyApplication() {
packages("org.foo.rest;org.bar.rest");
// do any other initialization here
}
}
<web-app>
<servlet>
<servlet-name>org.foo.rest.MyApplication</servlet-name>
</servlet>
...
<servlet-mapping>
<servlet-name>org.foo.rest.MyApplication</servlet-name>
<url-pattern>/resources</url-pattern>

...
