我使用Glassfish 4.1使用jersey 2.23.2部署RESTful webapp。
我尝试做的是在服务器启动时运行方法
我的web.xml
<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd" >
<web-app>
<display-name>XYZ</display-name>
<servlet>
<servlet-name>MyApplication</servlet-name>
<servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
<init-param>
<param-name>javax.ws.rs.Application</param-name>
<param-value>MyApplication</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>MyApplication</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
</web-app>
和MyApplication.java
import javax.annotation.PostConstruct;
import org.glassfish.jersey.server.ResourceConfig;
public class MyApplication extends ResourceConfig {
public MyApplication() {
packages("services");
}
@PostConstruct
public void post_construct () {
//The method I want to run
}
}
答案 0 :(得分:0)
我想您的解决方案无效,因为您的类不受容器管理,因此@PostConstruct
不会被评估。
您可以尝试以下操作:
import javax.annotation.PostConstruct;
import org.glassfish.jersey.server.ResourceConfig;
public class MyApplication extends ResourceConfig {
public MyApplication() {
packages("services");
post_construct(); // <-- here is the call
}
@PostConstruct
public void post_construct () {
//The method I want to run
}
}
如果这不起作用,这是一个“真正的”解决方案:
@Singleton
@Startup
public class InitializerBean {
@PostConstruct
public void onStartup() {
// do your method-call here
}
}
