I want to test a non-transactional method in the service layer when inner methods are transactional separately. I want to know what will happen if some method throws an exception. Does it properly roll back or not? I also tried rollbackFor but it did not help. Any suggestions?
- Spring v-2.5.1
app.properties
spring.datasource.url=jdbc:mysql://localhost:3306/test
spring.datasource.username=root
spring.datasource.password=root
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5InnoDBDialect
spring.jpa.hibernate.ddl-auto=create-drop
server.error.include-message=always
server.error.include-binding-errors=always
Controller
@PostMapping("/test")
public void test(){
service.test();
}
Service
@Service
public class UserService {
@Autowired
private UserRepository userRepository;
@Autowired
private PasswordEncoder passwordEncoder;
public void test() {
User user1 = new User();
String encodedPassword = passwordEncoder.encode("123");
user1.setUsername("username");
user1.setPassword(encodedPassword);
user1.setFirst_name("name1");
user1.setLast_name("family1");
save(user1);
User update = update(user1.getUsername());
throw new RuntimeException();// I expect Spring rollback all data for save and update methods
//but it seems data has been committed before an exception occur.
}
@Transactional
public void save(User user) {
if (userExists(user.getUsername()))
throw new ApiRequestException("Username has already taken!");
else {
User user1 = new User();
String encodedPassword = passwordEncoder.encode(user.getPassword());
user1.setUsername(user.getUsername());
user1.setPassword(encodedPassword);
user1.setFirst_name(user.getFirst_name());
user1.setLast_name(user.getLast_name());
user1.setCreate_date(user.getCreate_date());
user1.setModified_date(user.getModified_date());
user1.setCompany(user.getCompany());
user1.setAddresses(user.getAddresses());
userRepository.save(user1);
// throw new RuntimeException(); Similarly I expect rollback here.
}
}
@Transactional
public User update(String username) {
User userFromDb = userRepository.findByUsername(username);
userFromDb.setFirst_name("new username");
userFromDb.setLast_name("new lastname");
return userRepository.save(userFromDb);
}
}
