Integrating Spring Batch Admin into an existing application

Question

I have an application which uses Spring Batch and Spring MVC. I am able to deploy Spring Batch Admin as a separate war and use it against the same DB my application uses, though I would like to integrate it into my own application, possibly modify some of the views as well.

Is there an easy way to do this or do I have to fork it and go from there?

Answer 1

There is an easy way apparently according to this thread;

• Define a DispatcherServlet for Batch Admin in web.xml:

  <servlet>
      <servlet-name>Batch Servlet</servlet-name>
      <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
      <init-param>
          <param-name>contextConfigLocation</param-name>
          <param-value>classpath*:/org/springframework/batch/admin/web/resources/servlet-config.xml</param-value>
      </init-param>
      <load-on-startup>1</load-on-startup>
  </servlet>
  
  <servlet-mapping>
      <servlet-name>Batch Servlet</servlet-name>
      <url-pattern>/batch/*</url-pattern>
  </servlet-mapping>
  

• Add an override for resourceService in the root appContext:

  <bean id="resourceService"
  class="org.springframework.batch.admin.web.resources.DefaultResourceService">
      <property name="servletPath" value="/batch" />
  </bean> 
  

• Modify standard.ftl in spring-batch-admin-resources-1.2.0-RELEASE.jar to reflect the URL:

  <#assign url><@spring.url relativeUrl="${servletPath}/resources/styles/main.css"/></#assign>

Answer 2

If you are using Spring-batch-admin 1.2.1, you don't have to modify standard.ftl file. And you should add both servlet-config.xml and webapp-config.xml files from org/springframework/batch/admin/web/resources. Here are the steps (repeated again):

    <servlet>
        <servlet-name>Batch Servlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath*:/org/springframework/batch/admin/web/resources/servlet-config.xml,classpath*:/org/springframework/batch/admin/web/resources/webapp-config.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

Add resourceService bean in your applicationContext:

<bean id="resourceService"
class="org.springframework.batch.admin.web.resources.DefaultResourceService">
    <property name="servletPath" value="/batch" />
</bean>
