Difference between jersey1.X and jersey2.X

1: web. jersey1.X, the servlet container for loading jersey in xml, uses sun's com. sun. jersey. spi. container. servlet. servletContainerjersey2.X uses org of glassfish. glassfish. jersey. servlet. servletContainer2: Scan jerseyresourcejersey1.X to use sun's com. sun.

1: web. jersey1.X, the servlet container for loading jersey in xml, uses sun's com. sun. jersey. spi. container. servlet. servletContainer jersey2.X uses org of glassfish. glassfish. jersey. servlet. servletContainer 2: Scan jersey resource jersey1.X using sun's com. sun.

1: web. xml loads jersey's servlet container

Jersey1.X uses sun's com. sun. jersey. spi. container. servlet. ServletContainer

Jersey2.X uses org. glassfish. jersey. servlet. ServletContainer of glassfish.

2: Scan jersey resource

Jersey1.X uses sun's com. sun. jersey. config. property. packages

Jersey2.X Uses jersey. config. server. provider. packages of glassfish.

3: jersey2.X scan jersey resource using @ WebServlet of servlet3. No special web. xml configuration is required

For example:

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 can use the @ ApplicationPath annotation to load jersey resouce.

For example:

@ ApplicationPath ("/webapi /*")

Public class AirApplication extends Application {

@ Override

Public Set > GetClasses (){

Final Set > Classes = new HashSet > ();

Classes. add (MyResource. class );

Return classes;

}

}

5: jersey2.X can use web. xml to load the Application.

Jersey Web Application

Org. glassfish. jersey. servlet. ServletContainer

Javax. ws. rs. Application

Com. example. RestApplication
