Ich kann nicht @Autowire Feld in Java @ Konfigurationsdatei

Question

Mein Projekt ist eine Mischung aus Java-Konfiguration und XML-Konfiguration.

Bitte sehen Sie sich diese Dateien an. Ich kann nicht private DataSource dataSource;

@Configuration 
@EnableWebSecurity 
public class SecurityConfig extends WebSecurityConfigurerAdapter{ 


    @Autowired 
    private DataSource dataSource; 

    public void setDataSource(DataSource dataSource) { 
     this.dataSource = dataSource; 
    } 

    @Autowired 
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception { 
     auth 
       .inMemoryAuthentication() 
       .withUser("user").password("password").roles("USER"); 
    } 

und

Answer 1

Warum schreiben Sie nicht die Definition Ihres Bean in der Configuration-Klasse? Sie können alle Ihre Konfiguration dort haben. Sie benötigen keine applicationContext.xml und keine Configuration-Klasse.

Answer 2

Kein qualifizierendes Bean vom Typ [javax.sql.DataSource] für Abhängigkeit gefunden: erwartet mindestens 1 Bean - Es sieht so aus, als ob Ihre DataSource von einem anderen Typ ist. Gibt es eine Diskrepanz zwischen dem Typ der DataSource in Ihrer Config und XML? org.springframework.jdbc.datasource.DriverManagerDataSource und javax.sql.DataSource.

Answer 3

TL; DR - Korrigieren Sie Ihren Import so, dass er mit Ihrer Bean-Definition für Ihr automatisches Objekt übereinstimmt.

Ist es möglich, dass Ihr Import für das Objekt sich von der Bean-Definition in Ihrem Quell-XML unterscheidet?

In Ausnahme, sagt es deutlich:

„Keine Warte Bohne vom Typ [javax.sql.DataSource] für Abhängigkeit gefunden: erwartet, dass mindestens 1 Bohne, die qualifiziert sich als Kandidat für autowire diese Abhängigkeit. "

Wo in Ihrer Bean Definition Ihrer Feder xml, haben Sie:

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> 

Also, versuchen Sie Ihre Import-Anweisung beheben, um das gleiche wie die Bean Definition zu verwenden.

Answer 4

Ich denke, Sie müssen zuerst Ihre XML-Konfiguration in Java-Konfiguration einschließen.

@ImportResource("classpath:yourconfig.xml")
