如何从 IBM WebSphere 9 在 Spring Boot 中获取 JNDI 数据源

Question

Trying to deploy SpringBoot app to WebSphere 9 with using jdbc as SQL Server. I need to get jdbc username and password from websphere settings (not from app.properties).

As I understand, I can use InitialConfig.lookup() or JndiDataSourceLookup, but how could I find database, username and password?

Answer 1

Option 1:

Add the following property into application.properties

spring.datasource.jndi-name=jdbc/jndiName

add datasource bean definition in spring boot main class or config class

 @Autowired
 private Environment env;

@Bean
public DataSource dataSource() throws NamingException {
    return (DataSource) new JndiTemplate()
                             .lookup(env.getProperty("spring.datasource.jndi-name"));
 }

Option 2:

using Java standard API

DataSource ds = javax.naming.InitialContext.doLookup("jdbc/jndiName");
