Java Spring Quartz or CronTrigger loading multiple times Solution

Java Spring Quartz or CronTrigger loading multiple times with below Solution we can make load it once.

Spring Quartz or CronTrigger loading multiple times and its not problem with Quartz or CronTrigger configuration. this issue occurring because of the below "Web.xml" configuration issue .

1. Spring MVC Configuration(Web.xml).

 <servlet>
    <servlet-name>sampleapp</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>/WEB-INF/applicationContext.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>sampleapp</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>

In Above Web.xml Spring configuration we have to observe/change the below things.

1. The servlet "sampleapp" will load "applicationContext.xml/sampleapp-servlet.xml" file.
2. And the listener ContextLoaderListener will loads "sampleapp-servlet.xml" again.

To fix the above issues do the below changes in web.xml

Fix: 1. change the servet-name "sampleapp" to some other name.
2. change the "applicationContext.xml" to "projectname-servlet.xml", 
i.e: "javapages" is my project name.

Please find the below spring configuration web.xml after above changes.

 <servlet>
    <servlet-name>testapp</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>/WEB-INF/javapages-servlet.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>testapp</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>
