你能帮帮我吗？
这是我的aplication.properties文件：
spring.datasource.url = jdbc:mysql://localhost:3306/organizationsbd
spring.datasource.username = admin
spring.datasource.password = admin
spring.datasource.testWhileIdle = true
spring.datasource.validationQuery = SELECT 1
spring.jpa.show-sql = true
spring.jpa.hibernate.ddl-auto = update
spring.jpa.hibernate.naming.strategy = org.hibernate.cfg.ImprovedNamingStrategy
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
这是我的控制者：
@Controller
public class RegistrationController {
@RequestMapping(value = "/register", method = RequestMethod.GET)
public String registerForm(Model model) {
model.addAttribute("organization", new Organization());
return "register";
}
@RequestMapping(value = "/register", method = RequestMethod.POST)
public String registerSubmit(@ModelAttribute Organization organization, Model model) {
model.addAttribute("organization", organization);
create(organization);
return "result";
}
@RequestMapping("/create")
@ResponseBody
public String create(Organization organization) {
String ogranizationId = "";
try {
organizationDao.save(organization);
ogranizationId = String.valueOf(organization.getId());
} catch (Exception ex) {
return "Error creating the user: " + ex.toString();
}
return "User succesfully created with id = " + ogranizationId;
}
@Autowired
private OrganizationDao organizationDao;
}
