Spring boot JNDI datasource lookup failure - Name comp/env/jdbc not found in context “java:”

问题:

I have setup a spring boot (v 1.1.9) application to deploy as a WAR file. And I'm trying to integrate this web application with an existing data service module (added as a maven dependency).

Environment trying to deploy: WebSphere Application Server 8.5.5.4

The issue I'm facing is an application start-up failure when try to look-up a JNDI dataSource (jdbc/fileUploadDS) as below within the dependent data service module.

@Configuration @Profile("prod") public class JndiDataConfig implements DataConfig {      @Bean     public DataSource dataSource() throws NamingException {           Context ctx = new InitialContext();           return (DataSource) ctx.lookup("java:comp/env/jdbc/fileUploadDS");     }  } 

My Spring Boot configuration:

@Configuration @ComponentScan(basePackages = { "au.com.aiaa.fileupload.data.*", "demo" }) @EnableAutoConfiguration(exclude = { HibernateJpaAutoConfiguration.class, DataSourceAutoConfiguration.class }) public class SampleApplication extends SpringBootServletInitializer {      public static void main(String[] args) {         SpringApplication.run(applicationClass, args);     }      @Override     protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {         return application.sources(applicationClass);     }      private static Class applicationClass = SampleApplication.class;      @Bean     public static Properties fileUploadJndiProperties() throws NamingException {         JndiObjectFactoryBean jndiFactoryBean = new JndiObjectFactoryBean();         jndiFactoryBean.setJndiName("props/FileUploadProperties");         jndiFactoryBean.setExpectedType(Properties.class);         jndiFactoryBean.setLookupOnStartup(true);         jndiFactoryBean.afterPropertiesSet();         return (Properties) jndiFactoryBean.getObject();     }  } 

Note that I'm able to lookup props/FileUploadProperties successfully. But failing to do the same for a datasource.

My doubt is it is trying to load a EmbeddedWebApplicationContext which is not what I want.

The stack trace is:

What am I missing here? Even when I try to explicitly define the dataSource bean method in SampleApplication.java like below it fails with the same error.

@Bean     public static DataSource dataSource() throws NamingException {         JndiObjectFactoryBean jndiFactoryBean = new JndiObjectFactoryBean();         jndiFactoryBean.setJndiName("java:comp/env/jdbc/fileUploadDS");         jndiFactoryBean.setExpectedType(DataSource.class);         jndiFactoryBean.setLookupOnStartup(true);         jndiFactoryBean.setResourceRef(true);         jndiFactoryBean.afterPropertiesSet();         return (DataSource) jndiFactoryBean.getObject();     } 

I referred this and it says we need to set enableNaming() on servlet container? Can I do something similar for non-embedded web application context? Or is it purely a WAS 8.5 issue??

回答1:

You need to have resource reference with jdbc/fileUploadDS name in your web.xml. And make sure it is bound to actual datasource name during installation or via ibm-web-bnd.xml file.

Definition in web.xml:

jdbc/fileUploadDSjavax.sql.DataSourceContainerShareable

If you dont want to use web.xml, then in normal Java EE app you could just add in web component (servlet, filter) the following class annotation:

@Resource(name="jdbc/fileUploadDS", type=javax.sql.DataSource.class, lookup="jdbc/fileUploadDS") 

but I'm not Spring-boot expert, so don't know, if it will work or is possible there.

回答2:

I am facing the same problem. I don't know how to define tag in spring boot since there is no web.xml file in the spring boot.

So far what I came to know that we have to define it in the application file from where we start our spring application. I think we need to use this method to set the Datasource:

  @Bean(destroyMethod="")   @ConfigurationProperties(prefix="datasource.mine")   public DataSource dataSource() throws Exception {       JndiDataSourceLookup dataSourceLookup = new JndiDataSourceLookup();       return dataSourceLookup.getDataSource("java:jdbc/configurationFile");   } 

回答3:

I am able to connect my Spring-Boot application (deployed in Websphere Application Server 9) to WAS datasource. The following code worked for me, for connecting to DataSource:

@Bean(name = "WASDataSource") public DataSource WASDataSource() throws Exception {         JndiDataSourceLookup dataSourceLookup = new JndiDataSourceLookup(); return dataSourceLookup.getDataSource("DSNAME"); }     @Bean(name = "WASDataSourceJdbcTemplate") public JdbcTemplate jdbcTemplate_WASDS(@Qualifier("WASDataSource") DataSource dsDB2) { return new JdbcTemplate(dsDB2); } 

Note: The name of Datasource "DSNAME" is the name which appears on the UI of Websphere console. You can see that via -> Select Resources > JDBC > Data Sources.

Then I created jdbc template:

@Autowired @Qualifier("WASDataSourceJdbcTemplate") private JdbcTemplate db2WASTemplate;` 

And running query using the query method works fine :
db2WASTemplate.query()

I did not create any Web.xml or ibm-web-bnd.xml files

回答4:

I just configured spring boot with my custom datasource as follows:

@Bean @ConfigurationProperties("spring.datasource") public DataSource dataSource() {     return DataSourceBuilder.create().build(); } 

and inside the application.properties file I defined all datasource settings as usual

spring.datasource.driver-class-name= *** spring.datasource.url= *** spring.datasource.username= *** spring.datasource.password= *** spring.datasource.jndi-name=jdbc/myDB 

It works no nicely with @SpringBootApplication with all other default settings

Thanks
