봄 부팅 JNDI 응용 프로그램 설정

Question

JNDI를 사용하여 데이터베이스에 연결하는 테스트 용 스프링 부트 프로젝트를 만들려고합니다. 여기 내 application.properties : 여기

@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; 
    } 
} 

내 Application.java 파일입니다 :

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=; 

여기 내 설정 파일의

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

나는 이것을 실행하지만 난이 오류 얻을 때 :

내가 뭘 잘못 했니?

Answer 1

봄 부팅이 모든 일을 단순화하도록 설계되어 있습니다.

귀하의 속성에는 datasource url, username, password 또는 jndi-name이 있어야합니다. 두 옵션을 함께 사용하는 것은 아닙니다.

prefix가없는 application.properties의 데이터 소스와 관련하여 하나의 JNDI 이름 만 남겨 둡니다. Tomcat에서 성공적으로 구성했기를 바랍니다.

spring.datasource.jndi-name=jdbc/test 

그런 다음 AppConfig에서 datasource() 메소드를 제거하십시오. 데이터 소스를 삽입 (autowire)하고 사용하십시오.
