Here are steps to create a simple Spring Restful web services which will provide CRUD opertion and angularJS to call Spring MVC APIs.

1) Create a dynamic web project using maven in eclipse named “AngularjsSpringRestExample”

Maven dependencies

2)Now create pom.xml as follows:

pom.xml

Application configuration:

3) create web.xml as below:


4) 
create a xml file named springrest-servlet.xml in /WEB-INF/ folder.
Please change context:component-scan if you want to use different package for spring to search for controller.Please refer to spring mvc hello world examplefor more understanding.

Create bean class

5) Create a bean name “Country.java” in org.arpit.java2blog.bean.

Create Controller

6) Create a controller named “CountryController.java” in package org.arpit.java2blog.controller

Create Service class

7) Create a class CountryService.java in package org.arpit.java2blog.service
It is just a helper class which should be replaced by database implementation. It is not very well written class, it is just used for demonstration.

AngularJS view

8) create angularJSCrudExample.html in WebContent folder with following content:

Explanation :

    • We have injected $http as we have done in ajax example through controller constructor.

    • We have defined various methods depending on operations such as editCountry, deleteCountry, submitCountry
    • When you click on submit button on form, it actually calls POST or PUT depending on operation. If you click on edit and submit data then it will be put operation as it will be update on existing resource. If you directly submit data, then it will be POST operation to create new resource,
    • Every time you submit data, it calls refereshCountryData() to refresh country table below.
    • When you call $http, you need to pass method type and URL, it will call it according, You can either put absolute URL or relative URL with respect to context root of web application.

9) It ‘s time to do maven build.

Right click on project -> Run as -> Maven build

10) Provide goals as clean install (given below) and click on run

Run the application

10) Right click on angularJSCrudExample.html -> run as -> run on server
Select apache tomcat and click on finish
11) You should be able to see below page
URL : “http://localhost:8080/AngularjsJAXRSCRUDExample/angularJSCrudExample.html”


Lets click on delete button corresponding to Nepal and you will see below screen:

Lets add new country France with population 15000

Click on submit and you will see below screen.

Now click on edit button corresponding to India and change population from 10000 to 100000.

Click on submit and you will see below screen:

Lets check Get method for Rest API

12) Test your get method REST service
URL :“http://localhost:8080/AngularjsSpringRestExample/countries/”.

You will get following output:

As you can see , all changes have been reflected in above get call.

We are done with Spring Restful web services json CRUD example with angularjs If you are still facing any issue, please comment.

AngularJS tutorial:

If you getting 404 error with above steps, you may need to follow below steps:


1) If you are getting this warning into your Tomcat startup console log, then it can cause the issue
WARNING: [SetPropertiesRule]{Server/Service/Engine/Host/Context} Setting property ‘source’ to ‘org.eclipse.jst.j2ee.server: JAXRSJsonCRUDExample’ did not find a matching property.
This particular warning basically means that the element in Tomcat’s server.xml contains an unknown attribute source and that Tomcat doesn’t know what to do with this attribute and therefore will ignore it.
To resolve this in eclipse,
Remove the project from the server from the Server View. Right click on server -> add and remove
then remove project from server configuration.
Then run the project under the same server. Warning should be removed now
Or if warning still remains then
  • Go to server view
  • Double click on your tomcat server. It will open the server configuration.
  • Under server options check ‘Publish module contents to separate XML files’ checkbox.
  • Restart your server. This time your page will come without any issues.
2) Try to update Maven project.
Right click on project ->Maven-> update project
then
This should solve you issues.
