Spring boot configuration to run both in websphere and tomcat with jta

if required to decalare additional configuration from dependancy jar modules use component scan

@SpringBootApplication(scanBasePackages = {"au.com.myserver.app.*", "au.com.otherApp.service.*"})

if required to exclude all datasource autoconfiguration

@SpringBootApplication(scanBasePackages = {"aa.bb.cc.*", "aa.bb.cd.ee.*"}, exclude = {DataSourceAutoConfiguration.class, DataSourceTransactionManagerAutoConfiguration.class, HibernateJpaAutoConfiguration.class})

//or can specify on application.properties or application.yaml

spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration, org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration

creating Tomcat JNDI datasources

@Configuration@Profile({ "tomcat" })
public class TomcatWebConfiguration  {


    @Value("${spring.datasource.app.jdbc-url}")
    private String appDataSourceUrl;
    @Value("${spring.datasource.app.username}")
    private String appDataSourceUsername;
    @Value("${spring.datasource.app.password}")
    private String appDataSourcePassword;
    @Value("${spring.datasource.app.jndi-name}")
    private String appDataSourceJndi;

    @Bean    public TomcatServletWebServerFactory tomcatFactory() {
        return new TomcatServletWebServerFactory() {
            @Override  protected TomcatWebServer getTomcatWebServer(org.apache.catalina.startup.Tomcat tomcat) {

                tomcat.enableNaming();                

                return super.getTomcatWebServer(tomcat);

            }

            @Override  protected void postProcessContext(Context context) {

                // context                

                ContextResource resource = new ContextResource();

                resource.setName(appDataSourceJndi);                

                resource.setType(DataSource.class.getName());

                resource.setProperty("url", appDataSourceUrl);

                resource.setProperty("username", appDataSourceUsername);

                resource.setProperty("password", appDataSourcePassword);
                context.getNamingResources()
                        .addResource(resource);

            }

        };    

    }

}

for SprintBootTest use following to disable autoconfigure

@SpringBootTest(webEnvironment = WebEnvironment.DEFINED_PORT, properties = {"spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration,org.springframework.boot.autoconfigure.jdbc.DataSourceTransactionManagerAutoConfiguration,org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration"})
