How to catch JQuery $post in Spring Controller?

How to catch JQuery $post in Spring Controller? - java

I create a new Spring MVC project, then in index.jsp I send POST to the Spring Controller named springController.java. File index.jsp:
<%#page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<script type="text/javascript" src="//code.jquery.com/jquery-1.10.2.js"></script>
<script type="text/javascript" src="//code.jquery.com/ui/1.10.4/jquery-ui.js"></script>
<title>Welcome to Spring Web MVC project</title>
<script type="text/javascript">
$(document).ready(function(){
$("#testForm").submit(onFormSubmit);
});
function onFormSubmit(e){
data = $("#testForm").serialize();
// console.log(data);
$.post("/test/another");
e.preventDefault();
}
</script>
</head>
<body>
<form id="testForm">
<label>Imie: </label>
<input type="text" name="login">
<label>Nazwisko: </label>
<input type="text" name="password">
<input id="testPostButton" type="submit">
</form>
</body>
</html>
I try to catch POST in springController.java, here is the code:
/*
* To change this template, choose Tools | Templates
* and open the template in the editor.
*/
package newpackage;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;
/**
*
* #author Abc
*/
#Controller
#RequestMapping(/*method=RequestMethod.POST,*/ "/test")
public class springController {
/**
*
* #return
*/
#RequestMapping(/*method=RequestMethod.POST,*/ "/another")
#ResponseBody
public void test(){
System.out.println("Doszlo");
}
}
But sendind POST is not working, in WebInspector's console I get
POST http://localhost:8084/test/another 404 (Not Found)
In this moment I only want catch POST send from index.jsp. Unfortunately, I am newbie in Spring MVC and I don't know what I am doing wrong.
Here is dispatcher-servlet.xml:
<?xml version="1.0" encoding="UTF-8"?>

I have no idea what is wrong, why I can't ,,catch" POST from index.jsp in springController.java.
It is my first post on StackOverflow, I would be very happy if somebody decide to help me.
Greetings from Poland and thank you for help!
Here is file applicationContext, I have to paste file here because I am new and don't have enough reputation. Still in WebInspector's console I have the same message as earlier:

Try to uncomment
RequestMethod.POST
above the method definition
Also make sure that your controller is recognized as bean by spring. You annotated class with #Controller. To make it work you can add configuration to your applicationContext.xml:
<context:component-scan base-package="newpackage" use-default-filters="false">
<context:include-filter expression="org.springframework.stereotype.Controller" type="annotation"/>
</context:component-scan>

WARNING: No mapping found for HTTP request with URI [duplicate]

This question already has answers here:
Why does Spring MVC respond with a 404 and report "No mapping found for HTTP request with URI [...] in DispatcherServlet"?
(13 answers)
Closed 6 years ago.
When I'm trying to run my spring web application I am getting the following error:
org.springframework.web.servlet.DispatcherServlet noHandlerFound
WARNING: No mapping found for HTTP request with URI [/HibwenateWeb/index] in DispatcherServlet with name 'customerdispatcher
I am not able to load my home page. I gone through many articles releavent to the error, mostly every one is suggested to add <mvc:default-servlet-handler /> in dispatcher after adding that I am not getting that nohandler error but still the home page is not loading. I coudn't figure out the issue..Can any one help me on this?

You have to add the following elements to your web.xml.
<!-- The definition of the Root Spring Container -->
<context-param>
<param-name>contextConfigLocation</param-name>
<!-- provide the path for your customerdispatcher-servlet.xml -->
<param-value>/WEB-INF/customerdispatcher-servlet.xml</param-value>
</context-param>
<!-- Creates the Spring Container shared by all Servlets and Filters -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
Furthermore, you have to change the url-pattern element to:
<url-pattern>/</url-pattern>

I wrote a very simple prj in your structure, here it is.

This is the result. http://imgur.com/P51TSbk
Since you declare your customerdispatcher-servlet.xml in default way("dispatcher name"+"-servlet.xml"), so you don't need to add spring contextloader or set init-param to make the dispatcher servlet work.
Further info http://docs.spring.io/spring/docs/current/spring-framework-reference/html/mvc.html#mvc-servlet
Hope this can help you.
By the way, when declaring the url-pattern to the root path
<servlet-mapping>
<servlet-name>customerdispatcher</servlet-name>
<url-pattern>/</url-pattern> <= it's slash only, not /*
</servlet-mapping>
this subtle difference have made me an hour to find it...

HTTP Status 404 - Not Found in Spring 4 application

I have NetBeans Spring MVC project without any pom.xml file. I included jackson-databind-2.7.0-rc1.jar, jackson-core-2.7.0-rc1.jar and jackson-annotation-2.7.0-rc1.jar. But I got the following error pressing the button "Click me": HTTP Status 404 - Not Found. How can I avoid this error?

I have the same error when I chante method test() by the following code:

public #ResponseBody Test test()

Test t = new Test(1, "123");
return t;

Ok. Let' make this simple. No need to configure multiple controller handlers and multiple view resolvers. Make the changes below.
1. Change your web.xml dispatcher servlet mappings from *.html to /
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
2. In dispatcher-servlet.xml, replace your coniguration with this
3. In your ajax call, use url: "./ls-test", in the onclick() function

Spring MVC a href redirect to another page doesnt work

I am new in Spring MVC. I was practising with some example. And I am experiencing some problems.
When I run my project i get : HTTP Status 500 - Handler processing failed; nested exception is java.lang.NoClassDefFoundError: javax/servlet/jsp/jstl/core/Config.

You need to add this dependency to your pom.xml file

Hello World program with spring 4, netbeans IDE

This is my first attempt at spring and the question may seem to be very basic. I have spent lot of time trying to get it working but could not. From what I understand about spring there is a dispatcher servlet which routes all the incoming traffic to the appropriate controller.
As per the above understanding I have created a project using netbeans IDE. The code looks something like this.

Views should be stored under the WEB-INF folder so that
they are not accessible except through controller process.
This JSP is here to provide a redirect to the dispatcher
servlet but should be the only JSP outside of WEB-INF.

Why does it not get redirected to the hello world page.

Why do you have redirect to 'index.htm'
response.sendRedirect("index.htm")
But controller is mapped to:
#RequestMapping("/helloWorld")

I don't knw where it gone wrong.. evry time getting error 'Failed to load resource: the server responded with a status of 404 (Not Found)' . help me to fix this issue....

I think your web resources are not getting scanned and you are getting 404.
You should add something like this <context:component-scan base-package="com.web.resouces.package" /> in dispatcher-servlet.xml.Please see this link
http://www.mkyong.com/spring-mvc/spring-mvc-how-to-include-js-or-css-files-in-a-jsp-page/
Hope this helps.
