A small example of spring and Freemarker

Due to the need of the project and the need to use Freemarker, today is just a small example of a simple case study.

First configure Web. XML,

<servlet> <servlet-name>springmvc</servlet-name> <servlet-class> Org.springframework.web.servlet.dispatcherservlet</servlet-class> <init-param> <param-name> Contextconfiglocation</param-name> <param-value>classpath:applicationcontext.xml</param-value   > </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern>*.from</url-pattern> </ Servlet-mapping>

Then configure Applicationcontext.xml

  <bean id= "Freemarkerconfig"  class= " Org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer ">  <property name=" Templateloaderpath " value="/web-inf/pages/" />  <property name=" Freemarkersettings ">  <props>   <prop key=" defaultEncoding ">GBK </prop>  </props> </property> </bean> <bean id= " Freemarkerviewresolver " class=" Org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver " >  <property name= "Cache"  value= "true"  />  <property name= "prefix"  value= " />  <property name=" suffix " value=". FTL " />   <property name= "Order"  value= "1"  />  <property name= " ContentType ">   <value>text/html;charset=gbk</value>  </property> </bean> 

The

Then needs to write a simple entity class (omitted), and a controller

  @Controller @requestmapping ("/demo") public class testcontroller {  @RequestMapping ("/ Test.from ")  public string test (Model model) {  list<users> list =  new ArrayList<Users> ();   users user1 = new users ();   User1.setid (1);   user1.setusername ("ren ethereal"),   user1.setgender ("male");   user1.setsal ( 5000.0);   users user2 = new users ();   user2.setid (2);   User2.setusername ("text shortage");   user2.setgender ("male");   user2.setsal (5000.0);   users  user3 = new users ();   user3.setid (3);   user3.setusername ("Ren song");   user3.setgender ("male");   user3.setsal (5000.0);   users user4 = new  users ();   user4.setid (4);   user4.setusername ("Fall");   user4.setgender ("male");   //user4.setsAl (5000.0);   test null processing   list.add (user1);   list.add (User2);   list.add ( USER3);   list.add (user4);   model.addattribute ("username",  "slayers")   . AddAttribute ("pwd",  "123456"). AddAttribute ("userlist", list);  return  "user";  }

After the

We need to write an FTL file  USER.FTL

 
Such a simple example completes the above FTL in the ${(XXX) for null values!} This way of handling to avoid the error
