#ExceptionHandler returns a view instead of a String

I have written the below code in Spring for handling custom exceptions. My Exception handler is executing But it returns a view as shown below instead of a String. May I know what is wrong in my code. Thanks in advance.
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;
}
}

Can someone tell me why this exception occur.the other user entity is working correctly.
thanks

so after comment #dhs found answer
session factory needs to setPackagesToScan so do try this adding into annotatedClasses
com.onlineshopping.model.Product

spring Quartz scheduler not accessing database

here is my 'GenericQuartzJob' class
public class GenericQuartzJob extends QuartzJobBean

}
public void setBatchProcessorName(String name) {

Here is my MyRunnableJob Class

}MqttImplement mqtt=new MqttImplement();
mqtt.publishMessage();
//Run the Job. This code will run in the Spring context so you can use injected dependencies here.
}
}
Below is my MqttImplement class

Dao classes are #Transactional and #Repository.
in MqttImplement class service object is null i think autowired is not working with Quartz scheduler. Any suggestion????
i think autowired is kind of resolved. but
error is-- org.springframework.beans.NotWritablePropertyException: Invalid property 'sessionFactory' of bean class [org.springframework.scheduling.quartz.SchedulerFactoryBean]: Bean property 'sessionFactory' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?
i am new to it. so may be some foolish mistakes i have done, please have a look.

Have you tried #Autowired without static? Seems weird for me...
From other side you do this:
MqttImplement mqttPublishTms=new MqttImplement();
................
mqttPublishTms.publishMessage();
So, it's new not Dependency Injection. There is no surprise that the service property there is null.

Can any one help me to find out what wrong am I doing?

It seems that you're not scanning the package where you're named query resides, you scan com.nativeunlock.dao.**
<property name="packagesToScan" value="com.nativeunlock.dao.**"/>
and you're entity is within com.nativeunlock.dto

Spring PropertyPlaceholderConfigurer load from DB

Is it possible to load properties from DB with Custom Spring PropertyPlaceholderConfigurer?
and is it also possible that datasource provided to custom PropertyPlaceholderConfigurer use specific property file in classpath?
I could not find satisfied answer from following links?
http://www.mkyong.com/spring/spring-propertyplaceholderconfigurer-example/
http://www.codeproject.com/Articles/28893/Loading-Application-Properties-from-a-Database
PropertyPlaceholderConfigurer to look for DB values and use properties file as fallback
