Jersey @InjectParam creating a new Object instead of taking from Spring

问题

I have a Jersey Application using Spring I am using the @InjectParam in the hope (and what is written in the documentation) that Jersey would obtain the object from the Spring Container, but it seems Jersey is creating the object instead of asking Spring for it.

Is there a way of checking if the Spring IOC is registered with Jersey ?

web.xml

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>SpringDispatcher</servlet-name>
    <url-pattern>/*</url-pattern>
</servlet-mapping>
</web-app>

My class provide basic access to the factory but the factory is new

public FileStoreService(@InjectParam("dataAccessFactory") factory ) {  
   this.factory = factory;    
}

and i have added the @Component and still nothing.

回答1:

The wrong servlet was being used. It should be

<servlet-class>com.sun.jersey.spi.spring.container.servlet.SpringServlet</servlet-class>

The current one uses Jersey own container, which will only create objects using the default constructer. The Spring Servlet allows Jersey to attached to the Spring Container.
