#Controller
#RequestMapping("/customer")
public class CustomerController {
#Autowired
private CustomerService customerService;
#GetMapping("/all")
public String listCustomers(Model model)

List<Customer> theCustomers = customerService.getAllCustomers();
model.addAttribute("customers",theCustomers);
return "customer-all";

public void processCustomer(HttpServletRequest request, HttpServletResponse response, #ModelAttribute("CustomerDTO") Customer customerDTO) throws IOException {
customerService.addCustomer(customerDTO);
response.sendRedirect(request.getContextPath()+"/customer/all");
}
}
At the moment I'm able to read customers from database but method addCustomer doesn't work unless managed transcaction manually inside saveCustomer() method. I suspect that reading customers also does not work by #Transactional annotation.
Service

import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import java.util.List;
#Service
public class CustomerServiceImpl implements CustomerService {
#Autowired
private CustomerDao customerDao;
#Override
#Transactional
public List<Customer> getAllCustomers()
{
return customerDao.getCustomers();
}
#Transactional
#Override
public void addCustomer(Customer customer) {
customerDao.addCustomer(customer);
}
}
DAO
package com.adrianzaplata.project.dao;
import com.adrianzaplata.project.entities.Customer;
import org.hibernate.*;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
import java.util.List;
#Repository
public class CustomerDaoImpl implements CustomerDao {
#Autowired
private SessionFactory sessionFactory;
#Override
public List<Customer> getCustomers() {
Session session = sessionFactory.openSession();
try {
SQLQuery query = session.createSQLQuery("SELECT * from customer");
query.addEntity(Customer.class);
List<Customer> customers = query.list();
return customers;
} finally {
session.close();
}
}
#Override
public void addCustomer(Customer customer) {
Session session = sessionFactory.openSession();
session.save(customer);
}
}
I'm just trying to use #Transactional to help me reduce boilerplate code i have to use for hibernate but when i use #Transactional my logic from dao class does not execute. (No queries to database).

Basic Spring based WSSecurity client gets a null response

I've been following this tutorial to learn how to develop a basic spring client and server application using wssecurity (certificates).
The demo works beautifully, but i need to deploy my application on a wildfly server, so i had to change the example a bit in order to avoid the embedded tomcat, the changes are as follows:

#ResponsePayload
public GetBeerResponse getBeer(#RequestPayload GetBeerRequest request) {
GetBeerResponse beerResponse = new GetBeerResponse();
Beer beer = new Beer();
beer.setId(request.getId());
beer.setName("Beer name");
beerResponse.setBeer(beer);
return beerResponse;
}
}
I deployed the server application on my wildfly and i tried to call it using the same client application used in the tutorial. The service seems to answer correctly, the beerResponse object is correctly istantiated, but, as soon as the object is being sent back to the the client, i see it's NULL.
What am i missing?
Thanks in advance
Oh well, next time i'll read better. At the same link of my first post, a guy asked the same question in the comments, here is the solution: add a callBackHandler to the client configuration, and modify the securityInterceptor to use this handler.

securityInterceptor.setSecurementPassword("changeit");
securityInterceptor.setSecurementSignatureCrypto(getCryptoFactoryBean().getObject());
// encrypt the request
securityInterceptor.setSecurementEncryptionUser("server-public");
securityInterceptor.setSecurementEncryptionCrypto(getCryptoFactoryBean().getObject());
securityInterceptor.setSecurementEncryptionParts("{Content}{http://memorynotfound.com/beer}getBeerRequest");

securityInterceptor.setValidationCallbackHandler(securityCallbackHandler());
return securityInterceptor;
}

cryptoFactoryBean.setKeyStorePassword("changeit");
cryptoFactoryBean.setKeyStoreLocation(new ClassPathResource("client.jks"));
return cryptoFactoryBean;
}
#Bean
public Jaxb2Marshaller getMarshaller(){
Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
marshaller.setContextPath("com.memorynotfound.beer");

Whitelabel Error Page This application .... There was an unexpected error (type=Unauthorized, status=401). Unauthorized

When I run the application, it displays this error (error 401).
How fix this problem and thank's :
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing
this as a fallback. There was an unexpected error (type=Unauthorized,
status=401). Unauthorized

Swagger not working with Spring REST API

Hello i am trying to implement swagger with Spring REST, i am not using Spring Boot to create REST API's, i have used normal Spring REST API.
The problem when i run the application and if i navigate to this url
http://localhost:8080/spring-mvc-restfull-crud-example/swagger-ui.html
i am getting only the header of swagger-ui, there is nothing else. I am using Java config instead of XML config.

can you please anyone help me that what is wrong in this? is there anything that i need to add?
You have not defined Docket bean and neither you have used the #EnableSwagger2
The configuration of Swagger mainly centers around the Docket bean. Swagger 2 is enabled through the #EnableSwagger2 annotation. Refer the below code.
#Configuration
#EnableSwagger2
public class SwaggerConfig {
#Bean
public Docket customImplementation() {
return new Docket(DocumentationType.SWAGGER_2).pathMapping("/data").apiInfo(apiInfo());
}
private ApiInfo apiInfo() {
return new ApiInfo("ISW ADR Application",
"ADR or is another business line within the Issuer services business group."
+ "The primary functionalities of ADR are maintained within the DR system (mainframe) "
+ "Four main functionalities that are imported : "
+" 1) Dividend Announcements"
+ " 2) Depositary Service fees"
+ " 3) DR Fees"
+ " 4) DR Gross revenue.",
"ADR V2", "Terms of service", "xyz", "License of API", "API license URL");
}
}
You have not enabled swagger using #EnableSwagger2 and also have not returned a Docket Bean. Refer this.
#Configuration
#EnableSwagger2
public class SwaggerConfig {
#Bean
public Docket demoApi() {
return new Docket(DocumentationType.SWAGGER_2).select()
.apis(RequestHandlerSelectors.basePackage("com.example.demo"))
.paths(PathSelectors.regex("/person.*")).build();
}
}

Getting 404 when deploying Spring MVC web application to live server(Arvixe)

I'm trying to deploy a simple Spring MVC web application which is using java config(no xml files) to a live server. But it is giving only 404 error. These are the files i'm using.
pom.xml

</project>
Here, i edited the "warSourceDirectory" to "src" since there is no web.xml in this project.
AppInitializer
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.ServletRegistration;
import org.springframework.web.WebApplicationInitializer;
import org.springframework.web.context.support.AnnotationConfigWebApplicationContext;
import org.springframework.web.servlet.DispatcherServlet;
public class AppInitilizer implements WebApplicationInitializer {
public void onStartup(ServletContext container) throws ServletException {
AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
ctx.register(AppConfig.class);
ctx.setServletContext(container);
ServletRegistration.Dynamic servlet = container.addServlet("dispatcher", new DispatcherServlet(ctx));
servlet.setLoadOnStartup(1);
servlet.addMapping("/");
}
}
I also tried with the below initializer class instead of the above, but that's also not working.
import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;
public class AppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
#Override
protected Class<?>[] getRootConfigClasses() {
return new Class[] { AppConfig.class };
}
#Override
protected Class<?>[] getServletConfigClasses() {
return null;
}
#Override
protected String[] getServletMappings() {
return new String[] { "/" };
}
}
This is my AppConfig class;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.ViewResolver;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.view.InternalResourceViewResolver;
import org.springframework.web.servlet.view.JstlView;
#Configuration
#EnableWebMvc
#ComponentScan( basePackages = "com.spring.test" )
public class AppConfig {
#Bean
public ViewResolver viewResolver() {
InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
viewResolver.setViewClass(JstlView.class);
viewResolver.setPrefix("/WEB-INF/views/");
viewResolver.setSuffix(".jsp");
return viewResolver;
}
}
Controller class;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
#Controller
public class MainController {
#RequestMapping(value = "/login", method = RequestMethod.GET)
public String sayHello(ModelMap model) {
model.addAttribute("greeting", "Hello World from Spring MVC");
return "welcome";
}
}
After deploying the war file into public_html, i tried accessing this URL; www.domain.com/SpringProject/login, but i'm getting only 404 error, i don't know what is wrong with the above configurations. If any one knows please help me.
