Paramètre d'application Spring JNDI Boot

Question

J'essaye de créer un projet de démarrage de ressort de test qui se connecte à une base de données en utilisant JNDI. Voici mon application.properties:

spring.datasource.name=jdbc/test 
spring.datasource.driver-class-name=com.microsoft.sqlserver.jdbc.SQLServerDriver 
spring.datasource.jndi-name=java:jdbc/test 
spring.datasource.url=... 
spring.datasource.username=... 
spring.datasource.password=... 
spring.datasource.type=javax.sql.DataSource 
spring.datasource.separator=; 

Voici mon fichier de configuration:

@Configuration 
@EnableConfigurationProperties 
public class AppConfig { 
    @Bean 
    public TomcatEmbeddedServletContainerFactory tomcatFactory() { 
     return new TomcatEmbeddedServletContainerFactory() { 
      @Override 
      protected TomcatEmbeddedServletContainer getTomcatEmbeddedServletContainer(Tomcat tomcat) { 
       tomcat.enableNaming(); 
       return super.getTomcatEmbeddedServletContainer(tomcat); 
      } 
     }; 
    } 

    @Bean 
    @ConfigurationProperties(prefix = "spring.datasource") 
    public DataSource dataSource() { 
     JndiDataSourceLookup dataSourceLookup = new JndiDataSourceLookup(); 
     DataSource dataSource = dataSourceLookup.getDataSource("java:jdbc/test"); 
     return dataSource; 
    } 
} 

Voici mon fichier Application.java:

@SpringBootApplication 
public class DemoApplication { 
    public static void main(String[] args) { 
     SpringApplication.run(DemoApplication.class, args); 
    } 
} 

Quand je lance cela, mais je reçois cette erreur:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [com/example/AppConfig.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [javax.sql.DataSource]: Factory method 'dataSource' threw exception; nested exception is org.springframework.jdbc.datasource.lookup.DataSourceLookupFailureException: Failed to look up JNDI DataSource with name 'java:jdbc/test'; nested exception is javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial

Qu'est-ce que je fais mal?

Spring Boot est conçu pour simplifier tout ce que les choses.

Vous devriez avoir datasource url, username, password ou jndi-name dans vos biens, pas les deux options ensemble. Laisser un seul nom JNDI concernant la source de données dans application.properties sans préfixe.

J'espère que vous l'avez configuré sur votre Tomcat avec succès.

spring.datasource.jndi-name=jdbc/test 

Ensuite, supprimez la méthode datasource() de votre AppConfig. Il suffit d'injecter (autowire) la source de données et de l'utiliser.
