Ssh+jquery+ajax Framework Integration _ajax related

Recently learned the integration of SSH2 (Struts2+spring+hibernate), began to try to write a landing interface, the results found: if the use of Struts2 to page jump, the effect of the page is not good, at the same time can not be local refresh (that is, asynchronous submission verification).

So, I began to search the Internet solution, some say through a hidden iframe to achieve the effect, when I always feel trouble and not practical. Later asked the teacher, told me to use Ajax to achieve the desired effect, I found that there are many examples on the web are Ajax, but the missing is SSH2 (integrated) and AJAX integration (Ajax using the jquery framework).

Tell me about the effect I want:

Login page Click to submit after the background verification;

Validation successfully jumps to index. JSP;

Validation fails to execute a jquery script prompt user on this login page;

Required Packages:

SSH2 is used in the package, you also need to struts2 the following package:

Commons-beanutils-1.8.0.jar
Commons-collections-3.1.jar
Commons-fileupload-1.3.1.jar
Commons-io-2.2.jar
Commons-lang-2.4.jar
Commons-lang3-3.1.jar
Commons-logging-1.1.3.jar
Ezmorph-1.0.6.jar
Freemarker-2.3.19.jar
Json-lib-2.3-jdk15.jar
Ognl-3.0.6.jar
Struts2-core-2.3.16.3.jar
Struts2-json-plugin-2.3.16.3.jar
Xwork-core-2.3.16.3.jar

OK, start pasting code:

login.jsp

Password: <input id= "PassWord" name= "PassWord" type= "PassWord"/><br/>

 <input id= "button" type= "button" value= "Submit"/>
 </body>
 
 

Loginaction.java

Publicclass Loginaction extends Actionsupport {
  //Use @resource annotation inject condition property name to be consistent with ref to
  @Resource
  Fuserservice Fuserserviceimp;
  @Resource
  FUser FUser;
  Private String User;
  Private String PassWord;
  Private String result;
  Public String GetResult () {
    returnresult;
  }
  Publicvoid SetUser (String User) {this
    . user = user;
  }
  Publicvoid SetPassword (String PassWord) {this
    . PassWord = PassWord;
  }
  Public String Execute () throws Exception {
    HttpServletRequest request = Servletactioncontext.getrequest ();
    Get AJAX-handed data directly using the foreground's property name.
    Fuser.setuseremail (User);
    Fuser.setuserpassword (PassWord);
    if (Fuserserviceimp.checkuser (fUser)!=null) {
      //data returned to Ajax
      This.result = "true";
    } else{
      This.result = "false";
    }
    Return "Success";
  }

Struts.xml

<?xml version= "1.0" encoding= "UTF-8"?>
<struts>
  <!-This is the package
  to configure struts when we configure SSH--> <package name= "Struts" extends= "Struts-default" >
    <action name= "Login" class= "loginaction" >
    </action>
  </package>
  <!-in order for Ajax to invoke the action in spring to configure AJAX package-->
  <package Name= "Ajax_json" extends= "Json-default" >
  <!-the ID of this place is the value of the Ajax URL, class references the id-->
    of the spring configuration action <action name= "Login" class= "loginaction" > <result name= "Success" type=
      "json"/>
    </action >     
  </package>
</struts>

Other SSH2 frameworks are consolidated without changes so that the jquery framework Ajax can be integrated into the SSH2 framework for use!
