I am new to Spring and JPA, spent 5 days and didn't get any search results on the Internet. I want to save the object in SQL SERVER, the connection is correct, but when I write .flush (), I get an exception
The nested exception is javax.persistence.TransactionRequiredException: no transaction is running
This is my jpaContext.xml

This is my persistence.xml file:
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1" xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">
<persistence-unit name="test" >
<class>com.misha.model.Table1</class>
</persistence-unit>
</persistence>
This is my service implementation:
@Service("manService")
public class SaveManImpl implements SaveMan {
@Autowired
private ManRepositoryImpl manRepo;
@Transactional
public Table1 save(Table1 table) {
manRepo.save(table);
return null;
}
}
And finally, my Repository implementation:
@Repository("manRepository")
public class ManRepositoryImpl implements ManRepository {
@PersistenceContext
private EntityManager em;
public Table1 save(Table1 table){
em.persist(table);
em.flush();
return table;
}
}
From the exception, Spring can not see @Transactional annotation, am I right? I tried to put the annotation above the method of saving the repository, with no result, after that above the method of saving the service, the same here. thanks in advance
I call save method in my controller
package com.misha.controllers;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.transaction.annotation.Transactional;
import org.springframework.web.bind.annotation.RequestMapping;
import com.misha.model.Table1;
import com.misha.service.SaveMan;
@Controller
public class ManController {
@Autowired
SaveMan saveMan;
@RequestMapping(value="/test1")
public String saveMan(){
Table1 tab = new Table1();
tab.setName("name");
saveMan.save(tab);
return "saveMan";
}
}
