Exception handler is not executing in Spring project

I wrote the below code inorder to implement Spring Exception handling. When I run the code it needs to throw an error at the below line and the corresponding exception handler should execute. But, it is not executing. May I know what is wrong in my code. Thanks in advance
throw new SpringException("Error", retStatus);
Code:
#Controller
public class RestController {
#ExceptionHandler(SpringException.class)
public String handleCustomException(SpringException ex) {
String jsonInString = "{}";
JSONObject json = new JSONObject();
Map<String,String> errorMap = new HashMap<String,String>();
errorMap.put("errorMessage",ex.getMessage());
System.out.println("Inside exception handler");
json.putAll(errorMap);
jsonInString = json.toJSONString();
logger.info(jsonInString);
return jsonInString;
}
#RequestMapping(value = "/v1/dist_list/{emailId}/members", method = RequestMethod.GET)
public #ResponseBody String getDistributionListMember(#PathVariable String emailId) throws Exception, SpringException {
String retStatus = null;
retStatus = dataServices.getDistributionListMember(emailId, callerId);
if (!retStatus.isEmpty()) {
if (retStatus.contains("callerid is not valid")) {
throw new SpringException("Error", retStatus);
}
}
}
SpringException class
package com.uniteid.model;
import org.springframework.http.HttpStatus;
public class SpringException extends RuntimeException {
private static final long serialVersionUID = 1L;
private String errCode;
private String errMsg;
public String getErrCode() {
return errCode;
}
public void setErrCode(String errCode) {
this.errCode = errCode;
}
public String getErrMsg() {
return errMsg;
}
public void setErrMsg(String errMsg) {
this.errMsg = errMsg;
}
public SpringException(String errCode, String errMsg) {
this.errCode = errCode;
this.errMsg = errMsg;
}
}

Why I have this problem and how to fix it?

I resolved it by adding #Transactional annotation above the controller/service.

You have shown root-context.xml in your question but this context file doesn't have ViewResolver bean configuration. You must be having servlet context configuration file for Dispatcher Servlet (e.g. dispatcher-servlet.xml) configured in web.xml. Please add following configuration to your dispatcher-servlet.xml.
<tx:annotation-driven />
If you don't have xmlns:tx definition in your dispatcher-servlet.xml like other xmlns: definitions, then add it. Please make sure you have proper configuration for component-scan in dispacher servlet context.
<context:component-scan base-package="by.netcracker.artemyev.*" />
You can also refer to post #Transactional doesn't work in Spring Web MVC? where similar issue has been reported.

I encounter this issue when maintaining a legacy code, finally I realised from complex annotations.
it needs #EnableTransactionManagement on app level. otherwise #Transactional is not working

SpringMVC my SessionFactory in DAOimp doesn't work

I have this in my servlet:

</bean>
and my DaoImp
#Repository
#Transactional
public class UserDaoImp implements UserDao {
#Autowired
SessionFactory session;
public List<Users> list() {
return session.getCurrentSession().createQuery("from Users").list();
}
here is my HibernateUtil
private static final SessionFactory sessionFactory;
static {
try {
// Create the SessionFactory from standard (hibernate.cfg.xml)
// config file.
sessionFactory = new Configuration().configure().buildSessionFactory();
} catch (Throwable ex) {
// Log the exception.
System.err.println("Initial SessionFactory creation failed." + ex);
throw new ExceptionInInitializerError(ex);
}
}
public static SessionFactory getSessionFactory() {
return sessionFactory;
}
And After executing the application I have a NullPointerException:
SEVERE [http-nio-8084-exec-97] org.apache.catalina.core.StandardWrapperValve.invoke Servlet.service () for servlet [spring-web] in context with path [/ Holaspringmvc] threw exception [Request processing failed; Nested exception is java.lang.NullPointerException] with root cause
Java.lang.NullPointerException
At com.tricas.dao.UserDaoImp.list (UserDaoImp.java:32)
Please help me.

Be simpler. Just declare SessionFactory bean
#Bean
public AbstractSessionFactoryBean sessionFactoryBean(){
AnnotationSessionFactoryBean sessionFactoryBean = new AnnotationSessionFactoryBean();
sessionFactoryBean.setConfigLocation(new ClassPathResource("hibernate.cfg.xml"));
return sessionFactoryBean;
}
similar for LocalSessionFactoryBean
btw: did you define component-scan ?
<context:component-scan base-package="<my.base.package>" />

I found the error, results that I had to define in the service and in the controller also with #Autowired
Here is my Service.
#Autowired
UserDao usrdao;
//private UserDao usrdao = new UserDaoImp();
#Transactional
public List<Users> getAllUsers() {
return usrdao.list();
}
and here is my controller
#Autowired
UserService usrv;
//private UserService usrv = new UserService();
#RequestMapping(value = "/verusuarios", method = RequestMethod.GET)
public String listPersons(Model model) {
List<Users> list = usrv.getAllUsers();
model.addAttribute("user", new Users());
model.addAttribute("list", list);
return "verusuarios";
}
Additionally I must add to guide me from this answer: answer here

this.hibernateTemplate = hibernateTemplate;
}
public boolean regUser(com.imall.pojo.regUser rgUser)

System.out.println(rgUser.getfName());
try
{
System.out.println("in try--"+rgUser.getEmailId());
hibernateTemplate.save(rgUser);
return true;
}
catch(Exception e)
{
System.out.println("Catch");
e.printStackTrace();
return false;
}
}
Any help will be appreciated.
Here are the other code -
LoginController Method-
#Autowired
private registrationService regService;
#RequestMapping(value="/register.php",method = RequestMethod.POST)
public ModelAndView registerUser(#ModelAttribute("regDetails") regUser userReg)
{
System.out.println(userReg.getfName());
if(regService.regUser(userReg))
{
System.out.println("IF");
return new ModelAndView("success");
}
else
{
System.out.println("else");
return new ModelAndView("success");
}
}
The line 29 in RegistrationService is- hibernateTemplate.save(rgUser);
And this line System.out.println(rgUser.getfName()); is printing the name.

Ensure the applicationContext.xml has the bean dataSource defined.
The DAO should pass a constructor-arg and not a property since dataSource is a constructor-arg.
Annotate a constructor method and ensure it accepts a dataSource.
The dataSource passes is the same one defined in the applicationContext.xml:
<bean id="countryDao" class="com.crimetrack.jdbc.JdbcCountryDAO">
<constructor-arg index="0" ref="dataSource"/>
</bean>
#Repository
public class JdbcCountryDAO extends JdbcDaoSupport implements CountryDAO {
private final Logger logger = Logger.getLogger(getClass());
#Autowired
JdbcCountryDAO(DataSource dataSource) {
setDataSource(dataSource);
}
public List<Country> getCountryList() {
// ...

The error is that no dataSource or jdbcTemplate is wired into the JdbcCountryDao bean:
java.lang.IllegalArgumentException: 'dataSource' or 'jdbcTemplate' is required
However your XML config shows that you have the dataSource sent, so are you sure that this error occurs when using the posted version of the file?
Also, there is no need to have declare a #Autowired jdbcTemplate in a class that extends JdbcDaoSupport as the superclass provides this for you already.
