How to call method after finishing first transaction in spring mvc

In my Spring mvc application, calling following method , when click 'Save' button in jsp page.
#RequestMapping(value = "/add", method = RequestMethod.POST)
public String addUser(#ModelAttribute("user") #Valid User u,
BindingResult result, #ModelAttribute("category") UserCategory uc,
BindingResult resultCat, Model model, RedirectAttributes reDctModel) {
this.userService.addUser(u); // adding new user to DB
reDctModel.addFlashAttribute("msgSucess","Successfully saved..!");
this.sendEmail(u.getUsr_email(),"RDMS","Login Details"); // For sending mail
return "redirect:/users";
}
public String sendEmail(String recipientAddress,String subject,String message) {
// creates a simple e-mail object
SimpleMailMessage email = new SimpleMailMessage();
email.setTo(recipientAddress);
email.setSubject(subject);
email.setText(message);
// sends the e-mail
this.mailSender.send(email);
return "Result";
}
This is my applicationcontext
</bean>
<bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
<property name="host" value="smtp.gmail.com" />
<property name="port" value="587" />
<property name="username" value="myemailaddress#gmail.com" />
<property name="password" value="********" />
<property name="javaMailProperties">
<props>
<prop key="mail.transport.protocol">smtp</prop>
<prop key="mail.smtp.auth">true</prop>
<prop key="mail.smtp.starttls.enable">true</prop>
</props>
</property>
</bean>
The issue is, after adding sendEmail() ,it takes around 15 seconds to save the new record.Before adding this method it takes only 1 second.Can anybody guide me to reducing slowness of the programme or calling sendEmail() after finishing first transaction.Thanks in advance.

You have to create async service and configure your application for asynchronous usage, here you have spring tutorial. In async service you have to place your code for sending email. Below you can see sample code for 2 classes first is service second is application class,
import java.util.concurrent.Future;
import org.springframework.scheduling.annotation.Async;
import org.springframework.scheduling.annotation.AsyncResult;
import org.springframework.stereotype.Service;
import org.springframework.web.client.RestTemplate;
#Service
public class SampleService {
#Async
public Future sendEmail(String email) {
// here you can place your code for sending email
return new AsyncResult("email sent successful");
}
}
import java.util.concurrent.Future;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.scheduling.annotation.EnableAsync;
#SpringBootApplication
#EnableAsync
public class Application implements CommandLineRunner {
#Autowired
SampleService sampleService;
#Override
public void run(String... args) throws Exception {
Future page1 = sampleService.sendEmail("test#gmail.com");
while (!page1.isDone()) {
Thread.sleep(10);
}
System.out.println(page1.get());
}
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}

IllegalStateException: Cannot convert value of type to required type

Here's the error I'm receiving.

Here's the interface (FieldSetMapper.java)
package code;
import org.springframework.batch.item.file.transform.FieldSet;
import org.springframework.validation.BindException;
public interface FieldSetMapper<T> {
T mapFieldSet(FieldSet fieldSet) throws BindException;
}
Here's ProductFieldSetMapper.java
package code;
import org.springframework.batch.item.file.transform.FieldSet;
import org.springframework.validation.BindException;
public class ProductFieldSetMapper implements FieldSetMapper<Product> {
public Product mapFieldSet(FieldSet fieldSet) throws BindException {
// TODO Auto-generated method stub
Product product = new Product();
product.setId(fieldSet.readString("PRODUCT_ID"));
product.setName(fieldSet.readString("NAME"));
product.setDescription(fieldSet.readString("DESCRIPTION"));
product.setPrice(fieldSet.readBigDecimal("PRICE"));
return product;
}
}
And here's the class that I'm running (Runner.java)
package code;
import org.omg.PortableInterceptor.SYSTEM_EXCEPTION;
import org.springframework.batch.item.file.transform.FieldSet;
import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.validation.BindException;
public class Runner {
public static void main(String[] args) throws BeansException, BindException {
// TODO Auto-generated method stub
Product product;
ApplicationContext context =
new ClassPathXmlApplicationContext("FileReaderConfig.xml");
ProductFieldSetMapper obj = (ProductFieldSetMapper) context.getBean("FieldSetMapper");
product = (Product) obj.mapFieldSet((FieldSet)context.getBean("lineTokenizer"));
System.out.println(product.getDescription() + ""+product.getId()+""+product.getName());
}
}
I don't see where (or why for that matter)my code is attempting to convert a ProductFieldSetMapper into a FieldSetMapper (which is just an interface, I understand that won't work).
BTW, Product.java is a POJO with variables and their respective setters and getters.

The error was the result of me using my own interface rather than the one provided by Spring. I deleted my interface class and had ProductFieldSetMapper implement org.springframework.batch.item.file.mapping.FieldSetMapper after importing it. That solved the issue.

ProductFieldSetMapper obj =
(ProductFieldSetMapper) context.getBean("FieldSetMapper");
Should be
ProductFieldSetMapper obj =
(ProductFieldSetMapper) context.getBean("fieldSetMapper");
See your bean declaration.
<property name="fieldSetMapper">
<bean class="code.ProductFieldSetMapper" />
</property>

Here is code with some correction:
Runner.java (use DelimitedLineTokenizer class to tokenize a comma separated string into FieldSet that is further used to map it with an object (Product) via ProductFieldSetMapper class)
ApplicationContext context = new ClassPathXmlApplicationContext(
"FileReaderConfig.xml");
ProductFieldSetMapper obj = (ProductFieldSetMapper) context.getBean("fieldSetMapper");
DelimitedLineTokenizer tokenizer = (DelimitedLineTokenizer) context
.getBean("lineTokenizer");
FieldSet fieldSet = tokenizer.tokenize("1,Pepsi,Cold drinks,30");
Product product = (Product) obj.mapFieldSet(fieldSet);
System.out.println(product.getDescription() + "-" + product.getId() + "-"
+ product.getName());
Config xml file: (No need to declare any beans or jobs other than two defined below because you are not using it anywhere in you Main class)
<bean id="lineTokenizer"
class="org.springframework.batch.item.file.transform.DelimitedLineTokenizer">
<property name="names" value="PRODUCT_ID,NAME,DESCRIPTION,PRICE" />
</bean>
<bean id="fieldSetMapper" class="com.spring.batch.domain.ProductFieldSetMapper" />
ProductFieldSetMapper.java: (There is no need to define your custom FieldSetMapper)
import org.springframework.batch.item.file.transform.FieldSet;
import org.springframework.validation.BindException;
public class ProductFieldSetMapper implements org.springframework.batch.item.file.mapping.FieldSetMapper<Product> {
public Product mapFieldSet(FieldSet fieldSet) throws BindException {

The problem is in the controller method :
#RequestMapping(value = "/storeemployee",method = RequestMethod.POST, headers = {"Accept=text/xml, application/json"})
public Employee storeEmpRecord(#RequestBody Employee employee,HttpServletResponse resp,
ModelMap model)
{
System.out.println("Emp Id received : "+employee.getEmployeeId());
System.out.println("Emp Name received : "+employee.getEmployeeName());
// Employee empReturned = employeeBo.findByEmployeeId(1);
return employee;
}
Spring MVC does not (cannot) add objects to model automatically. You need to add the employee object to the ModelMap. The model map is then passed to the marshaling view, which looks for any objects that it can marshal, and marshals them to response.
Unable to locate object to be marshalled in model: {} Means the Marshalling View received a ModelMap with no objects that have the XStream annotations.
Hope this helps.

Customize SpringSecurity OAuth 2 Error Output (unauthorized)

We secure our REST services (for server to server communication, no user involved) with Spring Security OAuth2. However when one tries to access a protected resource in a browser, it will show:
<oauth>
<error_description>
An Authentication object was not found in the SecurityContext
</error_description>
<error>unauthorized</error>
</oauth>
We want this to be a custom page of our own choosing. Is there a way?
Setting the access-denied-page won't do. For one it requires the definition of a login page which we don't have as this is a pure server to server communication. For another this attribute is supposedly deprecated since Spring 3.0.. or something.
Anyway.. Debugged my way into the OAuth Error Handling. And found that the response seems to somehow get enriched with the information I see on the error page. Apparently no page rendering at all is done so it looks like there is no error page to replace..?!
At least we want to hide the fact that we use OAuth and just display a basic "Denied" text if we can't have a "real" page.. So maybe I'll have to extend the spring security handler or add a custom filter to modify the response?!
Maybe a redirect to our error page?
Thanks!
Edit
For our current setup check my other SO question here

I had to remove the oauth detail too and my solution was to implement my own OAuth2ExceptionRenderer
package org.some.nice.code;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.springframework.http.HttpEntity;
import org.springframework.http.HttpHeaders;
import org.springframework.http.HttpInputMessage;
import org.springframework.http.HttpOutputMessage;
import org.springframework.http.ResponseEntity;
import org.springframework.http.server.ServerHttpResponse;
import org.springframework.http.server.ServletServerHttpRequest;
import org.springframework.http.server.ServletServerHttpResponse;
import org.springframework.security.oauth2.provider.error.OAuth2ExceptionRenderer;
import org.springframework.web.context.request.NativeWebRequest;
import org.springframework.web.context.request.ServletWebRequest;
public class HeaderOnlyOAuth2ExceptionRenderer implements OAuth2ExceptionRenderer
{
private final Log logger = LogFactory
.getLog(MyOAuth2ExceptionRenderer.class);
public void handleHttpEntityResponse(HttpEntity<?> responseEntity,
ServletWebRequest webRequest) throws Exception
{
if (responseEntity == null)
{
return;
}
HttpInputMessage inputMessage = createHttpInputMessage(webRequest);
HttpOutputMessage outputMessage = createHttpOutputMessage(webRequest);
logger.info("filtering headers only...");
if (responseEntity instanceof ResponseEntity
&& outputMessage instanceof ServerHttpResponse)
{
((ServerHttpResponse) outputMessage)
.setStatusCode(((ResponseEntity<?>) responseEntity)
.getStatusCode());
}
HttpHeaders entityHeaders = responseEntity.getHeaders();
if (!entityHeaders.isEmpty())
{
outputMessage.getHeaders().putAll(entityHeaders);
}
}
private HttpInputMessage createHttpInputMessage(NativeWebRequest webRequest)
throws Exception
{
HttpServletRequest servletRequest = webRequest
.getNativeRequest(HttpServletRequest.class);
return new ServletServerHttpRequest(servletRequest);
}
private HttpOutputMessage createHttpOutputMessage(
NativeWebRequest webRequest) throws Exception
{
HttpServletResponse servletResponse = (HttpServletResponse) webRequest
.getNativeResponse();
return new ServletServerHttpResponse(servletResponse);
}
}
Then you will have to reference it within your spring context
<bean id="oauthAuthenticationEntryPoint" class="org.springframework.security.oauth2.provider.error.OAuth2AuthenticationEntryPoint">
<property name="realmName" value="theRealm" />
<property name="exceptionRenderer" ref="headerOnlyExceptionRender" />
</bean>
<bean id="clientAuthenticationEntryPoint" class="org.springframework.security.oauth2.provider.error.OAuth2AuthenticationEntryPoint">
<property name="realmName" value="theRealm/client" />
<property name="typeName" value="Basic" />
<property name="exceptionRenderer" ref="headerOnlyExceptionRender" />
</bean>
<bean id="oauthAccessDeniedHandler" class="org.springframework.security.oauth2.provider.error.OAuth2AccessDeniedHandler">
<property name="exceptionRenderer" ref="headerOnlyExceptionRender" />
</bean>
<bean id="headerOnlyExceptionRender" class="org.some.nice.code.HeaderOnlyOAuth2ExceptionRenderer"/>
Hope it helps.

hey the problem got resovled, after i had modified, the following..
1) applicationContext with mapping for the bean "productManager" with ref productDao.
2) ProductManager interface with new method call getProducts(), then implemenent in the SimpleProductManager and which call the ProductDao.getProducts(), where the sql query is being defined.
