User creation in alfresco through java

问题:

PersonServiceImpl personService = new PersonServiceImpl();
            PropertyMap ppOne = new PropertyMap(6);
            AuthenticationService authenticationService = new AuthenticationServiceImpl();
            AuthorityService aService = new AuthorityServiceImpl();
            if(authenticationService.authenticationExists("admin123")==false){
                authenticationService.authenticate("admin123","admin123".toCharArray());
            ppOne.put(ContentModel.PROP_USER_USERNAME,"admin123");
                ppOne.put(ContentModel.PROP_FIRSTNAME,"admin123");
                ppOne.put(ContentModel.PROP_LASTNAME,"Technologies");
                ppOne.put(ContentModel.PROP_EMAIL,"[e-mail]");
                ppOne.put(ContentModel.PROP_PASSWORD,"admin123");
                NodeRef nodeRef=personService.createPerson(ppOne);
            }

When ever i keep code like this if person is new person then also authenticationExits true...

If i keep true inplace of false then persionService.createPerson(ppOne) will raise null pointer exception...

Any body please help me...

回答1:

Can you just @Autowire the PersonService, AuthenticationService instead of creating object with "new".

Following is the working code snippet :

@Autowired
PersonService personService;
@Autowired
MutableAuthenticationService authenticationService;



public void createUser(User user) throws Exception {
    if (user.getUserName() != null) {
        if (authenticationService.authenticationExists(user.getUserName())) {
            throw new Exception("User" + user.getUserName() + " already exists.");
        } else {
            authenticationService.createAuthentication(user.getUserName(), user.getPassword().toCharArray());
            Map<QName, Serializable> properties = new HashMap<>();
            properties.put(ContentModel.PROP_USERNAME, user.getUserName());
            NodeRef personNodeRef = personService.createPerson(properties);
            user.setId(personNodeRef.getId());
        } 
    }
}
