Working example of spring watchservicedirectoryscanner - java

I'm struggling to implement a WatchServiceDirectoryScanner. I want to use the scanner to monitor new file uploads to a directory + sub directories. This will exist as part of a Spring boot MVC microservice. I can do this using Java 7's WatchService but would prefer a spring file integration style, AOP style
I have it registered as a #Bean in my app config but I'm struggling to figure out how to have it poll and scan a directory and then call... something (a message endpoint?) when a file is detected. Is anyone able to point me in the right direction for even conceptually how this is done. I cannot find an example implementation of this anywhere.
http://docs.spring.io/spring-integration/reference/html/files.html#_watchservicedirectoryscanner
http://docs.spring.io/spring-integration/api/org/springframework/integration/file/DefaultDirectoryScanner.html#listFiles-java.io.File-
here is my Spring appConfig:
public class appConfig {
#Bean
public DirectoryScanner scanner() {
return new WatchServiceDirectoryScanner("/uploads/test");
}
}

Java Spring - Configure Rest Endpoints with XML Configuration

i want to have something like a plugin system for Spring which are accessible through an REST endpoint.
So I was thinking I could simply implement a controller module as #RestController bean and add it to my beans definition.
Unfortunately I cannot figure out how to configure a #RestController and #RequestMapping using XML.
So far I think I have configured the a
This is my main class:
package me.example.app;
import org.springframework.context.ApplicationContext;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.context.annotation.*;
import java.lang.System;
import java.util.Properties;
#SpringBootApplication
#RestController
#ImportResource({"classpath:applicationContext.xml"})
public class GettingstartedApplication {
public GettingstartedApplication() {
System.out.println("INIT Application");
}
#RequestMapping("/")
String home() {
return "Hello World!";
}
public static void main(String[] args) {
ApplicationContext applicationContext = SpringApplication.run(GettingstartedApplication.class, args);
}
}
This is my resources/applicationContext.xml:
<?xml version="1.0" encoding="UTF-8"?>

This is my XMLController.java

public XMLController(String arg) {
System.out.println("INIT XMLController");
}
String home() {
return "XMLController";
}

Using Spring integration for messaging between two classes in the same application

I am trying to pass string messages from one class to another (from Class1 to Class2) within the same application so I am trying to solve it using Spring Integration.
My context.xml file looks like below:

public class Class1 implements Runnable {
#Autowired

public void someMethod() {
Class1 c = (Class1) appContext.getBean("springIntExample");
c.send();
}
public void send() {
getJmsTemplate().convertAndSend("empQueue", "one message to test");
}
public JmsTemplate getJmsTemplate() {
return jmsTemplate;
}
public void setJmsTemplate(JmsTemplate jmsTemplate) {
this.jmsTemplate = jmsTemplate;
}
...
}
Class Class2:
package com.my.package;
public class Class2 implements Runnable {
...
public void processMessage(String msg) {
System.out.println("message recived: " + msg);
}
...
}
Problem I have:
If I open my context.xml file, the below lines in context.xml are marked with a cross (error):
<int:poller fixed-delay="500" />
Anyway I can build and execute application but in run time an exception message saying fixe-delay not allowed in int:poller appears.
Also, is my implementation correct? I am not sure if after solving the problem commented it will work. I am new in spring sorry.

But now i want to replace this username and password authentication with a certificate. I prefere not to do this in xml, but rather implement this in my existing code as shown above.
We finaly figured this out some months ago, from what I remember our configuration looked like this.
add this to your web.xml
<servlet>
<servlet-name>mvc-dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>mvc-dispatcher</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
this needs to be present in your mvc-dispatcher-servlet.xml

SecurityPolicy.xml

<xwss:Sign includeTimestamp="true">

This is all done using the xws-security library from oracle, you need the following dependency for this.
<dependency>
<groupId>com.sun.xml.wss</groupId>
<artifactId>xws-security</artifactId>
<version>3.0</version>
<exclusions>
<exclusion>
<groupId>javax.xml.crypto</groupId>
<artifactId>xmldsig</artifactId>
</exclusion>
</exclusions>
</dependency>
We finnaly got this working after we found some good explanation about certificate authentication in this awesome book!

If you have any further questions regarding this implementation then just ask away! :d

Spring application does not exit using JmsTemplate

I am integrating Spring-4 and Active-MQ 5.8. I have written small test code. It send message properly but it does not exit.
The Sender Code is
package sample.jms.activemq;
import java.util.Map;
import org.springframework.jms.core.JmsTemplate;
public class MessageSender {
private final JmsTemplate jmsTemplate;
public MessageSender(final JmsTemplate jmsTemplate) {
this.jmsTemplate = jmsTemplate;
}
public void send(final Map map) {
jmsTemplate.convertAndSend(map);
}
}
** Configuration file is **
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans

</bean>
<!-- Message Sender Definition -->
<bean id="messageSender" class="sample.jms.activemq.MessageSender">

</bean>
</beans>
** The Main Class code is **
package sample.jms.activemq;
import java.util.HashMap;
import java.util.Map;
import org.springframework.context.support.AbstractApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
/**
*
*/
public class JMSMain {
public static void main(String a[]) {
AbstractApplicationContext context = new ClassPathXmlApplicationContext(
"/sample/jms/resources/Spring-Module.xml");
MessageSender sender = (MessageSender) context.getBean("messageSender");
Map<String, String> map = new HashMap<String, String>();
map.put("Name", "SampleName");
sender.send(map);
System.out.println("Exiting");
context.registerShutdownHook();
}
}
Try to add tcp://queueURL:61616?daemon=true to you config
The JMS just keeps listening messages so to close it it should be daemon.

migrate Spring app from XML to annotations

I've inherited a Spring 3 app that uses XML files to define and wire together the beans. I know that since Spring 2 these can mostly be replaced with annotations. I would like Spring to:
detect beans by scanning certain packages for classes with whatever annotation is used to indicate a Spring bean
attempt to autowire-by-name and field in a bean that I have marked with the relevant annotation
What are steps I need to take to make this happen?
The manual has all the info you need: http://static.springsource.org/spring/docs/3.1.0.M1/spring-framework-reference/html/beans.html#beans-annotation-config
The TL;DR version is that you need to add <context:annotation-config/> to your spring config and then annotate your beans with #Component and in your setter of properties annotate with #Autowired
I shall give you a xml configuration with it anotation based config equivalent respectively, so that you will easily see how to change your bean from xml to java and vice-versa

this file is named springrest-sevlet. actually you can give the name

the two files should be place in the folder "WEB-INF".
