I have been trying for more than an hour to display an image in my SpringBoot version 1.5.3 application.
I'm trying to display an image in my html page, which is the path:
And have used the image as:
<img src="images/DataServicesAdminAppLogo.png" width="40" height="40" class="d-inline-block align-top" alt="" hspace="10"/>
in my html page. But in vain. The image is not getting displayed.
Can someone please help?

I want to update one column of my database. The column name is status and the type is Enum('waiting' , 'accepted' , 'rejected')
I want to update this column when I click on link:

Reject

Session session = sessionFactory.openSession();
Query q = session.createQuery("from Vacation where id = :reqid ");
q.setParameter("reqid", id);
Vacation vacation = (Vacation) q.list().get(0);
vacation.setStatus(action);
session.update(vacation);

I have seen this approach in this tutorial.
When I click on links, everything looks good. But the column value does not change. Could someone explain this problem?
According to the documentation http://docs.spring.io/spring-framework/docs/3.2.2.RELEASE/spring-framework-reference/html/beans.html#beans-factory-lazy-init the below should not be instatiating MyDatabase yet I can clearly see this is the case in the afterPropertiesSet method of the HibernateDatabase class when debugging. If I remove MyDatabaseEntityManagerFactory then this does not occur. However this should not matter given that MyDatabaseEntityManagerFactory is also lazy - it should not cause MyDatabase to initialise.
Either I'm misunderstanding the part of the docs that say that a lazy bean referencing another lazy bean shouldn't cause it to initialise or there is a fundamental problem in Spring here. Can anyone shed some light on this or possibly suggest an alternative to what I want to achieve?
Thanks.

Am I missing any other library here? Any help is much appreciated.
You are missing the actual Thymeleaf jar. You included the Spring jar that provides the integration but you missed the actual implementation of it.
Download the jar from here

I have a spring project. There are two property files. one property file is config in dbConfig.xml and I cannot change it. I have my own appConfig.xml
I have the following in it
<util:properties id="configProps" location="classpath:spring/config.properties" />
<bean id="createDummyDataTask" class="com.merc.spring.CreateDummyData" scope="step">
<property name="srcFolder" value="${configProps.srcDir}"/>
</bean>
using either srcDir or configProps.srcDir does not seem to work.
${} works only for property files loaded by the context:propertyplaceholder. If you are using spring 3.0 you can use #{} which is processed as a Spel (spring expression language). The following should work.
<util:properties id="configProps" location="classpath:spring/config.properties" />
<bean id="createDummyDataTask" class="com.merc.spring.CreateDummyData" scope="step">
<property name="srcFolder" value="#{configProps.srcDir}"/>
</bean>
Here how we resolved it
