我使用以下内容：
我遇到了 java.lang.StringIndexOutOfBoundsException：
的问题这是我的springMVC.xml（servlet）

这是我的模型Anexo.class

/* Getters and Setters*/
我的AnexoDaoImpl
@Repository
@Transactional
public class AnexoDaoImpl implements AnexoDao{
@Autowired
private SessionFactory session;
@Override
public List<Anexo> anexos() {
return session.getCurrentSession().createQuery("from Anexo ").list();
}
@Override
public void ingresarModificar(Anexo anexo) {
session.getCurrentSession().saveOrUpdate(anexo);
}
我的AnexoService
@Service("anexoService")
public class AnexoService {
@Autowired
private AnexoDao anexodao;
@Transactional
public List<Anexo> getAllAnexo() {
return anexodao.anexos();
}
@Transactional
public void crearModificar(Anexo u) {
anexodao.ingresarModificar(u);
}
我的AnexoController
@Controller("anexoController")
public class AnexoController {
@Autowired
private AnexoService anexoserv;
@RequestMapping(value = "/veranexos", method = RequestMethod.GET)
public String listPersons(Model model) {
List<Anexo> list = anexoserv.getAllAnexo();
model.addAttribute("anexo", new Anexo());
model.addAttribute("list", list);
return "anexo";
}
@RequestMapping(value = "/anexo/add", method = RequestMethod.POST)
public String addPerson(@ModelAttribute("anexo") Anexo p) {
anexoserv.crearModificar(p);
return "redirect:/veranexos";
}
@RequestMapping("/edita/{idanexo}")
public String editPerson(@PathVariable("idanexo") int id, Model model) {
model.addAttribute("anexo", anexoserv.getById(id));
model.addAttribute("list", anexoserv.getAllAnexo());
return "anexo";
}
@RequestMapping("/removea/{idanexo}")
public String removePerson(@PathVariable("idanexo") int id) {
Anexo p = new Anexo();
p = anexoserv.getById(id);
anexoserv.eliminar(p);
return "redirect:/veranexos";
}
最后我的观点是anexo.jsp
