从1.X到2.X：
1：web.xml加载jersey的servlet容器
jersey1.X使用的是sun的com.sun.jersey.spi.container.servlet.ServletContainer
jersey2.X使用的是glassfish的org.glassfish.jersey.servlet.ServletContainer
2：扫描jersey resource
jersey1.X使用的是sun的com.sun.jersey.config.property.packages
jersey2.X使用的是glassfish的jersey.config.server.provider.packages
3：jersey2.X可以使用servlet3的 @WebServlet扫描jersey resource。不需要特别配置web.xml
例如：
import javax.servlet.annotation.WebInitParam;
import javax.servlet.annotation.WebServlet;
import org.glassfish.jersey.servlet.ServletContainer;
@WebServlet(initParams = @WebInitParam(name = "jersey.config.server.provider.packages", value = "com.example"), urlPatterns = "/webapi/*", loadOnStartup = 1)
public class AirServlet extends ServletContainer {
private static final long serialVersionUID = 1L;
}
4：jersey2.X可以使用@ApplicationPath注解，加载jersey resouce。
例如：
@ApplicationPath("/webapi/*")
public class AirApplication extends Application {
@Override
public Set<Class<?>> getClasses() {
final Set<Class<?>> classes = new HashSet<Class<?>>();
classes.add(MyResource.class);
return classes;
}
}
5：jersey2.X可以使用web.xml加载Application
<servlet>
<servlet-name>Jersey Web Application</servlet-name>
<servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
<init-param>
<param-name>javax.ws.rs.Application</param-name>
<param-value>com.example.RestApplication</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Jersey Web Application</servlet-name>
<url-pattern>/webapi/*</url-pattern>
</servlet-mapping>
web.xml相关设置：
<servlet>
<servlet-name>rest_test</servlet-name>
<servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
<init-param>
<param-name>jersey.config.server.provider.packages</param-name>
<param-value>com.test.jersey</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>rest_test</servlet-name>
<url-pattern>/api/*</url-pattern>
</servlet-mapping>
