I'm creating a Spring MVC Maven module based project so I have divided every layer into a maven module. When I try to run a basic site, code compiles fine but I get the error:

You need to mvn clean install in parent module to install the other module to local repo before you run your web module alone.
Or you can mvn clean install -am in web module, so that it will build the depended modules.
Please change the packaging to jar in service module, or just remove it, the default packaging is jar.
<packaging>jar</packaging>
<name>croz-service</name>
Go to the folder which contains the project pom file. Then get the cmd and run
mvn clean install
If it is failed, try it after deleting the target folder

I agree with M.Deinum, please correct these notes first of all. Further you should delete your Dispatcher-servlet.xml because you have a FileSystemXmlApplicationContext and have defined all of your beans in xml loaded there. Then please delete <listener> and <context-param> elements in web.xml and configure your aspect like this:
<aop:aspectj-autoproxy />
<!-- Aspect -->
<bean id="loggingAspect" class="Logging" />
I try to deploy the application, but the console show me this error, I'm not familiar with Spring MVC and Spring scheduler. This is my first project.

This program was running before I tried setting up the Spring-Scheduler. When I tried adding this component especially putting on the <task:annotation-driven /> tag on Beans.xml, this is where the error happened. Do you know any idea how to properly fix this configuration in order to run the scheduler?
Thanks and appreciate your help!
Add the following dependency to your pom.xml
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-aop</artifactId>
<version>3.2.3.RELEASE</version>
</dependency>
I am attempting to use a #Service class in my messaging application, however the class is not instantiated via #Autowire when I try from a generic class. It is only instantiated when I use the Controller.
Here is my controller:
package hello;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.messaging.handler.annotation.MessageMapping;
import org.springframework.messaging.handler.annotation.SendTo;
import org.springframework.messaging.simp.SimpMessageSendingOperations;
import org.springframework.messaging.simp.SimpMessagingTemplate;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import hello.Application;
#Controller
public class HelloController {
#Autowired
private MessageSender sender;
#RequestMapping(value="/", method=RequestMethod.GET)
public String index() {
return "index";
}
#MessageMapping("/hello")
#SendTo("/topic/greetings")
public Greeting greeting(HelloMessage message) throws Exception {
System.out.println("Sending message...");
beginRoute(message.getName());
sender.greet("thunder");
return new Greeting("Hello, " + message.getName() + "!");
}
public void beginRoute(String message) {
Application.startBody(message);
}
}
The above call to sender.greet is successful.
Here is the other class I attempt to use the service in:
package com.routing.integration;
import hello.*;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.messaging.simp.SimpMessageSendingOperations;
import org.springframework.messaging.simp.SimpMessagingTemplate;
import org.springframework.stereotype.Component;
#Component
public class modifier {
#Autowired
private MessageSender sender;
public boolean adder(String words) throws Exception {
sender.greet(words);
}
}
When I attempt to call sender.greet as above, I get a NullPointerException and when debugging, I find that sender is null at the time of the call to sender.greet. Is the service class not instantiating in modifier?
Finally, here is the MessageSender service class:
#Service
public class MessageSender {
#Autowired
private SimpMessagingTemplate template;
#RequestMapping(value="/hello", method=RequestMethod.POST)
public void greet(String greeting) {
Greeting text = new Greeting("Goodbye, " + greeting + "!");
this.template.convertAndSend("/topic/greetings", text);
}
}
How can I ensure that #Autowire instantiates the MessageSender in every class?
EDIT
Here is where the call to modifier is made. It is made from a camel route:

EDIT 2
Here is my main class that calls ComponentScan:
package hello;
import org.apache.camel.ProducerTemplate;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.support.ClassPathXmlApplicationContext;
#Configuration
#EnableAutoConfiguration
#ComponentScan(basePackages = {"hello", "com.routing.integration"})
public class Application {
static ApplicationContext context = null;
static ProducerTemplate camelTemplate = null;
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
System.out.println("----------------------\nSpringBootComplete\n----------------------");
startBody("startup");
}
public static void startBody(String message) {
if (context == null) {
context = new ClassPathXmlApplicationContext("camelspring.xml");
camelTemplate = context.getBean("camelTemplate", ProducerTemplate.class);
}
if (message != "startup"){
camelTemplate.sendBody("activemq:queue:testQSource", message);
}
}
}
Your Application class should look like this:
#Configuration
#ComponentScan(basePackages = {"hello", "com.routing.integration"})
#EnableAutoConfiguration
#ImportResource("classpath:camel.xml")
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
Where camel.xml is the xml configuration file that contains your camel definitions.
If you need any of the beans defined in the xml configuration, like camelTemplate in your xml, you can get a reference of it like this, for example:
package hello;
import javax.annotation.Resource;
import org.apache.camel.ProducerTemplate;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
#RestController
public class MyController {
#Resource(name="camelTemplate")
private ProducerTemplate template;
#RequestMapping("/")
String home() {
System.out.println(template);
return "Hello World!";
}
}
As I said in the comments, don't create an app context manually. Register the beans you want with #Component, #Service, #Configuration and #Bean etc. If you need xml configuration that is difficult to reproduce in Java code, use #ImportResource.
In the xml config file you have, you can replace browserBean bean with a #Controller annotation placed on the hello.HelloController class.
Your activemq bean could translate to something like this in Java Config:
#Configuration
public class Config {
#Bean
public ActiveMQComponent activemq() {
ActiveMQComponent comp = new ActiveMQComponent();
comp.setBrokerUrl("tcp://localhost:61616");
return comp;
}
}
