I'm trying to setup LightAdmin page for my web application, I'm following https://github.com/la-team/light-admin. After following this step a see this error: 

 14:36:55.705 [localhost-startStop-1] DEBUG o.s.b.f.s.DefaultListableBeanFactory - Destroying singletons in org.springframework.beans.factory.support.DefaultListableBeanFactory@77bc4d5: defining beans [dataSource,userJDBCTemplate,teamJDBCTemplate,entityManagerFactory,transactionManager]; root of factory hierarchy

Could you help me? I'm trying to have admin page to create/update/delete/show Users and Teams. Or is there a better way how to do it?

The message is referring to an absence of persistence.xml file. This file is usually holding references of the entities you defined for Hibernate/JPA.

Based on the files you submitted I was not completely able to reproduce your issue, do you have a way to share your project on GitHub ? Can you provide a bit extra insights about how you're deploying it ?

I took a quick look at your project. I don't see where you are using jpa, it seems you are using jdbctemplate for data access.

Why don't you remove these lines from your config and see if that gets you farther.

<bean id="entityManagerFactory"
    class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="jpaVendorAdapter">
        <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" />
    </property>
</bean>

<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
    <property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>

If you configure jpa related beans you are telling Spring-Boot not to auto-configure, and then you are responsible for replacing the "magic" that the framework does for you.

Spring boot should provide reasonable default configurations. You can add specific configuration later when-and-if you start using JPA(entities, repositories, etc) to access your data.

In your HomeController could you try this:

@Autowired
private UserJDBCTemplate userJDBCTemplate;

@Autowired
private TeamJDBCTemplate teamJDBCTemplate;

instead of this:

ApplicationContext context =  new ClassPathXmlApplicationContext("root-context.xml");

    UserJDBCTemplate ubd =(UserJDBCTemplate)context.getBean("userJDBCTemplate");
    TeamJDBCTemplate tbd =(TeamJDBCTemplate)context.getBean("teamJDBCTemplate");
