Je crée une application Web à l'aide de Spring, Hibernate, Struts et Maven.
J'obtiens l'erreur ci-dessous lorsque j'exécute mvn clean install
commande:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'com.project.action.PasswordHintActionTest': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.project.action.PasswordHintAction com.project.action.PasswordHintActionTest.action; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [com.project.action.PasswordHintAction] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}
Voici la classe qui a la dépendance Autowired:
import com.opensymphony.xwork2.Action;
import org.project.model.User;
import org.proejct.service.UserManager;
import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.subethamail.wiser.Wiser;
import static org.junit.Assert.*;
public class PasswordHintActionTest extends BaseActionTestCase {
@Autowired
private PasswordHintAction action;
@Autowired
private UserManager userManager;
@Test
public void testExecute() throws Exception {
// start SMTP Server
Wiser wiser = new Wiser();
wiser.setPort(getSmtpPort());
wiser.start();
action.setUsername("user");
assertEquals("success", action.execute());
assertFalse(action.hasActionErrors());
// verify an account information e-mail was sent
wiser.stop();
assertTrue(wiser.getMessages().size() == 1);
// verify that success messages are in the request
assertNotNull(action.getSession().getAttribute("messages"));
}
}

J'ai ajouté à ma configuration de contexte pour analyser les dépendances Autowired. Mais je ne sais pas pourquoi il donne toujours cette exception.
J'ai également essayé de l'ajouter de la manière suivante, mais j'obtiens toujours la même exception

MISE À JOUR:
voici l'action d'indication de mot de passe
import org.project.model.User;
import com.project.webapp.util.RequestUtil;
import org.springframework.mail.MailException;
import org.springframework.security.core.userdetails.UsernameNotFoundException;

import Java.util.List;
public class PasswordHintAction extends BaseAction {
private static final long serialVersionUID = -4037514607101222025L;
private String username;
/**
* @param username The username to set.
*/
public void setUsername(String username) {
this.username = username;
}
/**
* Execute sending the password hint via e-mail.
*
* @return success if username works, input if not
*/
public String execute() {
List<Object> args = new ArrayList<Object>();
// ensure that the username has been sent
if (username == null) {
log.warn("Username not specified, notifying user that it's a required field.");
args.add(getText("user.username"));
addActionError(getText("errors.requiredField", args));
return INPUT;
}
if (log.isDebugEnabled()) {
log.debug("Processing Password Hint...");
}
// look up the user's information
try {
User user = userManager.getUserByUsername(username);
String hint = user.getPasswordHint();
if (hint == null || hint.trim().equals("")) {
log.warn("User '" + username + "' found, but no password hint exists.");
addActionError(getText("login.passwordHint.missing"));
return INPUT;
}
StringBuffer msg = new StringBuffer();
msg.append("Your password hint is: ").append(hint);
msg.append("\n\nLogin at: ").append(RequestUtil.getAppURL(getRequest()));
mailMessage.setTo(user.getEmail());
String subject = '[' + getText("webapp.name") + "] " + getText("user.passwordHint");
mailMessage.setSubject(subject);
mailMessage.setText(msg.toString());
mailEngine.send(mailMessage);
args.add(username);
args.add(user.getEmail());
saveMessage(getText("login.passwordHint.sent", args));
} catch (UsernameNotFoundException e) {
log.warn(e.getMessage());
args.add(username);
addActionError(getText("login.passwordHint.error", args));
getSession().setAttribute("errors", getActionErrors());
return INPUT;
} catch (MailException me) {
addActionError(me.getCause().getLocalizedMessage());
getSession().setAttribute("errors", getActionErrors());
return INPUT;
}
return SUCCESS;
}
}
Mise à jour 2:
applicationContext-struts.xml:
<bean id="passwordHintAction" class="com.project.action.PasswordHintAction" scope="prototype">
<property name="userManager" ref="userManager"/>
<property name="mailEngine" ref="mailEngine"/>
<property name="mailMessage" ref="mailMessage"/>
</bean>
Utilisez la numérisation des composants comme indiqué ci-dessous, si com.project.action.PasswordHintAction
est annoté d'annotations de stéréotypes
<context:component-scan base-package="com.project.action"/>
MODIFIER
Je vois votre problème, dans PasswordHintActionTest
vous effectuez un câblage automatique PasswordHintAction
. Mais vous n'avez pas créé de configuration de bean pour que PasswordHintAction
se connecte automatiquement. Ajoutez une annotation de stéréotype (@Component, @Service, @Controller
) à PasswordHintAction
comme
@Component
public class PasswordHintAction extends BaseAction {
private static final long serialVersionUID = -4037514607101222025L;
private String username;
ou créez une configuration xml dans applicationcontext.xml
comme
<bean id="passwordHintAction" class="com.project.action.PasswordHintAction" />
Vous devez fournir un candidat pour le câblage automatique. Cela signifie qu'une instance de PasswordHint doit être connue pour apparaître de manière à pouvoir deviner qu'elle doit la référencer.
Veuillez fournir le responsable de la classe de PasswordHint et/ou la définition du bean Spring de cette classe pour plus d'assistance.
Essayez de changer le nom de
PasswordHintAction action;
à
PasswordHintAction passwordHintAction;
afin qu'il corresponde à la définition du bean.
