}
i searched stackoverflow for any solution to a similar error, but i didn't find any, any solution suggested to fix this ?

Instead of :
return ResponseEntity.ok(hospitals) ;
Try this :
return ResponseEntity<List<hospitals>>(hospitals);

check the object at line 64 it return null

Hello Esma and welcome to stackoverflow.
Since you declared explecitely your bean of type ExpDao with #Bean annotation in the SpringWebConfig.js, The bean registred in the spring context is expenceDao which is the same method name in this code section:
#Bean
public ExpDao expenceDao() {
ExpDao exp = new ExpDao();
exp.setTemplate(com.esma.dao.ExpDao.class);
return exp;
}
So Spring container will create and register a bean of type ExpDao with name (or id ) expenceDao (which is the name of the method expenceDao()
and then you ask spring with this section of code to inject a bean with name expDao which is not found.
#Controller
public class FormController {
#Autowired
ExpDao dao;
// the rest of the code
}
So spring will return a NoSuchBeanDefinitionException because it didn't found a bean with name expDao.
In order to work, you can just change the method name expenceDao() to expDao() in SpringWebConfig.java file in order that spring create the bean with name expDao and not expenceDao.
Thanks.

Posting this for completeness and clarification of the question, in case others run into this problem (basically a recap of the comments above).
The DB being used was MySQL 8.0 and the problem was caused by an outdated mysql-connector-java.
As suggested in this answer, the solution was to update the connector.

It seems as if the Character-Set of your database and you java application are somehow not compatible.
It seems to be a known issue with MySQL, as you may see here: java.sql.SQLException: Unknown initial character set index '255' received from server for connector 8.0.11
But there are probably similar issues with other DBMS as well.
In Addition you may change the characterEncoding "java-side" as you can see in the stacktrace:
Caused by: java.sql.SQLException: Unknown initial character set index '255' received from server. Initial client character set can be forced via the 'characterEncoding' property.

IllegalArgumentException: "Object" is not a known Entity type

So, i'm doing a project in JAVA EE, with JPA (Glassfish Server 4.1.2).
But got this error when I'm doing persist with my Facade :

Cannot run SpringMVC/Hibernate CRUD on localhost

I am new into Spring/Hibernate, trying to set up a simple CRUD using SpringMVC/Hibernate following this tutorial:
https://www.youtube.com/watch?v=zKVYjJjNSak
Every time I run this app on my Tomcat 7 server, I get the following warning:

The structure of the project is the following:pom.xml is in
C:\Users\Jeddid\workspace\SpringMVCHibernateExample
JSPs are in:
C:\Users\Jeddid\workspace\SpringMVCHibernateExample\src\main\webapp\WEB-INF\jsp\customer
config.properties is in
C:\Users\Jeddid\workspace\SpringMVCHibernateExample\src\main\resources
HibernateConfig.java, WebConfig.java and WebInitializer.java are in
C:\Users\Jeddid\workspace\SpringMVCHibernateExample\src\main\java\springmvc_example\config
and the rest of the .java classes are in the corresponding folders(i.e.model is in
C:\Users\Jeddid\workspace\SpringMVCHibernateExample\src\main\java\springmvc_example\model
,
controller is in
C:\Users\Jeddid\workspace\SpringMVCHibernateExample\src\main\java\springmvc_example\controller
,CustomerService.java and CustomerServiceImpl.java are in servive, etc)

The error says:
No mapping found for HTTP request with URI
[/SpringMVCHibernateExample/customer]
it is because, You have mapped it to /customer/list, you should try
http://localhost:8080/SpringMVCHibernateExample/customer/list
Update:
Answer to your Question in the comment
Change Your jdbc.url to the following:
(1) remove / at the end (2) remove the spaces before and after =
jdbc.url=jdbc:mysql://localhost:3306/springmvc
