SSH+Jquery+Ajax framework integration

This article introduces to you the implementation of partial refresh based on SSH Jquery Ajax integration. Interested friends should read this article together

After recently learning the integration of SSH2 (Struts2 Spring Hibernate), I started to try to write A login interface, and it was found that if you only use struts2 to jump to the page, the effect of the page will not be very good, and partial refresh (that is, asynchronous submission verification) will not be possible.

So, I started searching for solutions on the Internet. Some said that the effect could be achieved through a hidden iframe, but I always found it troublesome and impractical. Later, I asked the teacher and told me that using ajax can achieve the desired effect. I also found that there are many examples of ajax on the Internet, but what is missing is the integration of SSH2 (integrated) and ajax (ajax uses the jQuery framework ).

Talk about the effect I want:

Click submit on the login page to perform background verification;

Jump to index.Jsp upon successful verification;

If verification fails, a jQuery script will be executed on this login page to prompt the user;

Required packages:

In addition to the packages used by SSH2, the following packages of struts2 are also required:

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

Okay, start posting the code:

login.jsp

Account:

Password:

LoginAction.java

publicclass LoginAction extends ActionSupport { //使用@Resource注解注入条件属性名与 ref要一致才可 @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(); //获取ajax传过来的数据直接使用前台的属性名即可获取。 fUser.setUserEmail(User); fUser.setUserPassWord(PassWord); if(fUserServiceImp.CheckUser(fUser)!=null){ //返回给ajax的数据 this.result = "true"; }else{ this.result = "false"; } return"success"; } }

Struts.xml

The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
