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;
}
}

I wrote this code in the Service part of my java webapp project:
#Service
#Transactional
public class PersonService extends BaseService {
#PersistenceContext
private EntityManager entityManager;
public void insert(Person person) {
entityManager.persist(person);
}
public boolean checkUserName(String userName) {
try {
System.out.println("Entity null ni");
Person person = (Person) entityManager.createQuery("select entity from person entity where entity.USER_NAME=:userName")
.setParameter("userName", userName)
.getSingleResult();
if (person == null)
return true;
else {
return false;
}
} catch (Exception e) {
e.printStackTrace();
return false;
}
}
}
When I tried to insert a new record without using the checkUserName method, the record would be inserted correctly and entityManager was not null in this condition but when I wanted to check repetitive userName I got NullPointerException.I checked every Object in my code that could be null finally I understand entityManager is null.why entityManager is null in Spring Transaction.this is spring.xml

Maybe are you instantiating PersonService calling new PersonService() ? In this case Spring is not performing any operation and thus field 'entityManager' is null. You must get a bean from your Application Context
applicationContext.getBean(PersonService.class);
Or invoking it from a test or a controller
#RestController
#GetMapping("people")
public class PersonController() {
#Autowired
private PersonService personService;
#PostMapping
public void home(#RequestBody Person person) {
personService.insert(person);
}
}

I am importing a spring xml configuration file from another project using import resource. The resource is apparently found since there is no error message saying it isn't, but none of the beans get loaded. Is there something I'm doing wrong here? I should note that when I run my integration tests from within eclipse it all works fine, but it blows up when running the same integration test from within a maven build.

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.
I have an Spring+Hibernate/Flex application that needs to switch dynamically between database schemas. To accomplish that I implemented a AbstractRoutingDataSource following this article. Unfortunately to change between dataSource's doesn't work.
Someone could help me?
I followed this link: Spring + Hibernate SessionFactory + AbstractRoutingDataSource
My code is:

</property>
