Spring Boot Using Embedded Tomcat with JNDI

问题:

I am using Spring Boot with Embedded Tomcat and attempting to use JNDI but getting the following error:

javax.naming.NameNotFoundException: Name [jdbc/dataSource]

Any tips would be greatly appreciated.

Here is my code:

@Configuration
public class TomcatJndiConfiguration{

@Value("${database.driver}")
private String driverClassName;

@Value("${database.url}")
private String databaseUrl;

@Value("${database.username}")
private String databaseUsername;

@Value("${database.password}")
private String databasePassword;

@Bean
public TomcatEmbeddedServletContainerFactory tomcatFactory() {
    return new TomcatEmbeddedServletContainerFactory() {

        @Override
        protected TomcatEmbeddedServletContainer getTomcatEmbeddedServletContainer(
                Tomcat tomcat) {
            tomcat.enableNaming();
            return super.getTomcatEmbeddedServletContainer(tomcat);
        }

        @Override
        protected void postProcessContext(Context context) {
            ContextResource resource = new ContextResource();
            resource.setName("jdbc/dataSource");
            resource.setType(DataSource.class.getName());
            resource.setProperty("driverClassName", driverClassName);
            resource.setProperty("url", databaseUrl);
            resource.setProperty("password", databaseUsername);
            resource.setProperty("username", databasePassword);
            context.getNamingResources().addResource(resource);
        }
    };
}

@Bean
public DataSource dataSource() throws IllegalArgumentException, NamingException {
    JndiObjectFactoryBean bean = new JndiObjectFactoryBean();
    bean.setJndiName("jdbc/dataSource");
    bean.setLookupOnStartup(true);
    bean.setProxyInterface(DataSource.class);
    bean.setResourceRef(true);
    bean.afterPropertiesSet();
    return (DataSource) bean.getObject();

}

回答1:

You need to set lookupOnStartup to false on the JndiObjectFactoryBean.

Alternatively, if you need the lookup to work during startup, then this answer may be of interest.

Edit: you've also set the JNDI name on your JndiObjectFactory bean incorrectly. It needs to be java:comp/env/jdbc/myDataSource not jdbc/dataSource.

You use a different name when you're looking up the resource versus when you registered it as the registration automatically places the resource beneath java:comp/env/.

回答2:

If you are using spring boot, no need for all of that class. It is already configured in @EnableAutoConfiguration or @SpringBootApplication

Just put the following in your application.xml file or equivalent in application.yml file

spring.datasource.driverClassName=JDBCDriverClassName
spring.datasource.url=databaseUrl
spring.datasource.username=databaseUsername
spring.datasource.password=databasePassword
spring.datasource.jndi-name=java:jdbc/dataSource
