我正在使用Spring Mvc和JPA，实际上我在创建数据库之前做了实体（我现在将数据存储在内存中），但是当我尝试启动应用程序时，它会抛出：

应用程序崩溃的init方法首先设置Menu值
private void obtieneMenus(MenuRepository menuRepo) {
Menu menuBarra = new Menu();
menuBarra.setNombre("inicio");
menuBarra.setUrl("/");
menuRepo.save(menuBarra);
Menu menuRegistro = new Menu();
menuRegistro.setNombre("signup");
menuRegistro.setUrl("/signup");
menuRegistro.setParentMenu(menuRepo.findByUrl(menuBarra.getUrl()));
menuRepo.save(menuRegistro);
Menu menuLogin = new Menu();
menuLogin.setNombre("signin");
menuLogin.setUrl("/signin");
menuLogin.setParentMenu(menuRepo.findByUrl(menuBarra.getUrl()));
menuRepo.save(menuLogin);
Menu menuPerson = new Menu();
menuPerson.setNombre("person");
menuPerson.setUrl("/person");
menuPerson.setParentMenu(menuRepo.findByUrl(menuBarra.getUrl()));
menuRepo.save(menuPerson);
Menu menuCreate = new Menu();
menuCreate.setNombre("personCreate");
menuCreate.setUrl("/person/create");
menuCreate.setParentMenu(menuRepo.findByUrl(menuPerson.getUrl()));
menuRepo.save(menuCreate);
Menu menuListado = new Menu();
menuListado.setNombre("personList");
menuListado.setUrl("/person/list");
menuListado.setParentMenu(menuRepo.findByUrl(menuPerson.getUrl()));
menuRepo.save(menuListado);
然后我初始化Profile（但我认为这不是问题）并最终设置AccessMenu
private List<AccessMenu> obtieneAccesos(List<Menu> menus, List<Profile> perfiles){
List<AccessMenu> permisos = new ArrayList<AccessMenu>();
AccessMenu acceso;
for(Menu menu:menus){
acceso = new AccessMenu();
acceso.setMenu(menu);
for(Profile perfil : perfiles){
acceso.setProfile(perfil);
if("/person/list".equals(menu.getUrl()) && "ROLE_p1".equals(perfil.getNombre())){
acceso.setAccess(false);
}else{
acceso.setAccess(true);
}
permisos.add(acceso);
}
}
return permisos;
}
现在，我不知道问题出在初始化方法还是JPA标签中......
答案 0 :(得分：1)
尝试从Menu.java的mappedBy属性中的OneToMany标记更改accesMenu属性。
@OneToMany(mappedBy="menu")
private Set<AccessMenu> accessMenu = new HashSet<AccessMenu>();
