spring Quartz scheduler not accessing database - java

here is my 'GenericQuartzJob' class
public class GenericQuartzJob extends QuartzJobBean
{
private String batchProcessorName;
public String getBatchProcessorName() {
return batchProcessorName;
}
public void setBatchProcessorName(String name) {
// System.out.println("jo"+name);
this.batchProcessorName = name;
}
protected void executeInternal(JobExecutionContext jobCtx) throws JobExecutionException
{
try {
// System.out.println("jo");
SchedulerContext schedCtx = jobCtx.getScheduler().getContext();
ApplicationContext appCtx =
(ApplicationContext) schedCtx.get("applicationContext");
java.lang.Runnable proc = (java.lang.Runnable) appCtx.getBean(batchProcessorName);
proc.run();
}
catch (Exception ex) {
// ex.printStackTrace();
throw new JobExecutionException("Unable to execute batch job: " + batchProcessorName, ex);
}
}
}
Here is my MyRunnableJob Class
#Configuration
#ComponentScan("com.ehydromet.service")
public class MyRunnableJob implements Runnable {
//#Resource private SpringService myService;
#Autowired
public UserService service;
#Override
public void run() {
// System.out.println("hu");
try{
service.getAllAdminUser();
}catch(Exception ex){
System.out.println(ex.getMessage()+" MyRunnableJob");
}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
public class MqttImplement implements MqttCallback {
#Autowired
private static UserService service;
#RequestMapping("/publish")
public void publishData(ModelMap map){
MyTask.map=map;
pubTopic="tmsdata";
susTopic="tmsack";
if(initializeMqTTParameters() ){
if(suscribeForAck()){
// new ClassPathXmlApplicationContext("spring-quartz.xml");
AbstractApplicationContext context = new AnnotationConfigApplicationContext(AppConfig.class);
}
}
// initializeMqTTParameters();
// suscribeForAck();
// publishMessage();
}
public void publishMessage(){
try{
// System.out.print("sending ");
Received received=service.getReceivedDataToPublishTMS();
if(received!=null){
System.out.print("sending you not null");
String publisgMSG=createMessageToPublish(received);
pubMessage="lava," ;
publishMessageTms();
}else{
System.out.println("null hora");
}
}catch(Exception ex){
System.out.println("hora"+ex.getLocalizedMessage()+" "+ex.toString());
}
}
}

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.

#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 {

return errCode;
}
public void setErrCode(String errCode) {
this.errCode = errCode;
}
public String getErrMsg() {

}
public void setErrMsg(String 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

Spring Batch execution time with In-Memory Metadata

I am new to Spring batch and I am trying to use Spring Batch with restartable feature. I am using MapJobRepositoryFactoryBean as Job repository. Everything looks fine. But when I run the same job multiple times I could see the execution time increasing considerably. I guess some memory leak is happening.If no job is running, I am cleaning the repository as well. But no luck. How do I know whats happening exactly. After running the same job for 4-5 times, the execution time is going to 2-3 times of the first execution.

Don't use the MapJobRepositoryFactoryBean unless it's for testing. That's all it's intended for.
You shouldn't be building a new Job instance with every call to the controller. If you have stateful components within a step, declare them as step scoped so that you get a new instance per step execution.
The Map based JobRepository keeps everything in memory. That's the idea. So as you execute more and more jobs, the repository is going to grow...eating up your space in memory.
For launching a job in a controller, give something like this a try:
#RestController
public class JobLaunchingController {
#Autowired
private JobLauncher jobLauncher;
#Autowired
private Job job;
#RequestMapping(value = "/", method = RequestMethod.POST)
#ResponseStatus(HttpStatus.ACCEPTED)
public void launch(#RequestParam("name") String name) throws Exception {
JobParameters jobParameters =
new JobParametersBuilder()

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

Just in case here is the git repo for this project:
http://github.com/dmcquillan314/YouthMinistryHibernate
Let me know if any other information about this error is needed and I'll edit the post.
Any ideas are greatly appreciated. Thanks in advance.

You have overridden the default entity name, which would have been the simple name of the class, in the Group class:
#Entity(name="GROUP_DETAILS")
Therefore you cannot use Group as entity name in your query. There are two options to fix that:
If you use "GROUP_DETAILS" in your HQL, the query should succeed. Alternatively you can omit the name attribute of the Entity annotation and keep the HQL as it is.
