Can't create RestTemplate() instance from spring-web

I am using tomcat web application and rest webservice
when I insert data I get exception !
My class CustomerProxy:

iCustomerProxy.insertCustomer(customerDTO);
FacesContext.getCurrentInstance().addMessage(null, new FacesMessage(FacesMessage.SEVERITY_INFO, "Added Successfully", ""));
}
}
and the Exeption after inserting data that I debug and Find out Exception is for this :
RestTemplate restTemplate = new RestTemplate();

Any help would be appreciated.

Yup, as #Kayaman pointed out in comments, adding spring core dependency should solves it.
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>5.0.2.RELEASE</version>
</dependency>

The problem was for my other dependencies version
I changed them and problem solved

Shiro using spring gives " Shiro INI configuration was either not found or discovered to be empty/unconfigured."

I was able to get shiro running with shiro.ini and spring but I want to use shiro annotations and so i was trying to go for shiro-spring without ini file. but this is giving me hard time,

Take a look at the 1.4+ release, the Spring integration has been updated (for Spring, and Spring Boot).
But for your specific problem, it looks like you are trying to use a the EnvironmentLoaderListener. When using Spring, you will need to let Spring handle the lifecycle of loading your components.
For an example see: https://github.com/apache/shiro/blob/1.3.x/samples/spring-hibernate/src/main/webapp/WEB-INF/web.xml

How to return text_html type response in Jersey

I am developing a REST API using jersey jax-RS. This consumes data in JSON format and produces the output in html format.
When I set the MediaType for #Produces as TEXT_HTML and #Consumes as #APPLICATON_JSON and requested the 'GET' query on POSTMAN REST client, it gave me the following error:
org.apache.catalina.core.StandardWrapperValve invoke

On searching about this on the internet, I did not come across any useful solution except it was mentioned to download the genson jar and add it. After adding it as external jar in Eclipse (Java EE) MAVEN Project, it still gave the same exception which I guess is due to the fact that this jar is for json MediaType and is not used in the context of html content type.
Basically, I want to produce the content as HTML. How can I do it? I am entirely new to Jersey and the concept of REST API.

import org.apache.cxf.jaxrs.client.WebClient;
public class TestClient {
static final String REST_URI = "http://localhost:8080/RestfulSample/Restful";
public static void main(String[] args) {
WebClient client = WebClient.create(REST_URI);
/*
//Get
client.path("login").path(new Integer(1234)).accept(MediaType.TEXT_PLAIN);
String loginResponse = client.get(String.class);
System.out.println(loginResponse); */
//Post
client.path("logout").accept(MediaType.TEXT_PLAIN);
String logoutResponse = client.post("1024").toString();
System.out.println(logoutResponse);
}
Here i have no problem in accesing login(Get) method and it is working as expected.
But when i tried to access logout(Post) method i am getting the below error,
WARNING: No operation matching request path "/RestfulSample/Restful/agentLogout" is found, Relative Path: /agentLogout, HTTP Method: POST, ContentType: application/xml, Accept: text/plain,. Please enable FINE/TRACE log level for more details.

Could you please correct my mistake
Thanks,

#Path("/logout/{ext}"). You need another path segment after /logout. Whatever the value of {ext} should be
client.post("1024") is the body of the request. #PathParam is for the URI, so you need to add 1024 to the URI path, i.e. path("logout").path("1024"). Right now without the 1024 in the path, the endpoint doesn't exist (hence 404).
If you want to put the data in the POST body, then change it to #Path("/logout"), take out the #PathParam, and make the method param type String. You will need to parse it yourself

Unable to get basic implementation of Freemarker working

I am trying to configure a Freemarker template from a Servlet like so:
import java.io.IOException;
import java.io.StringWriter;
import java.util.HashMap;
import java.util.Map;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import freemarker.template.Configuration;
import freemarker.template.Template;
import freemarker.template.TemplateException;
#WebServlet("/Controller")
public class Controller extends HttpServlet {
// class fields
private static final long serialVersionUID = 1L;
private static final String views = "/WEB-INF/views/";
public Controller(){
}
// used to handle any get requests i.e. webpage navigation
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
Configuration conf = new Configuration();
conf.setClassForTemplateLoading(Controller.class, views);
conf.setDefaultEncoding("UTF-8");
Template indexTemplate = conf.getTemplate("index.ftl");
StringWriter writer = new StringWriter();
Map<String, Object> indexMap = new HashMap<String, Object>();
indexMap.put("name", "Chris");
try {
indexTemplate.process(indexMap, writer);
} catch (TemplateException e) {
e.printStackTrace();
}
System.out.println(writer);
}
}
But I get the following error when I startup the Tomcat server:
