Multiplos dataSources com Spring Boot

Fala ai Patrick, de boa ?

Acho que essa leitura vai te ajudar a implementar o que deseja : https://medium.com/@joeclever/using-multiple-datasources-with-spring-boot-and-spring-data-6430b00c02e7

Vou dar uma lida... Porém tem idéia de como configura utilizando JNDI.

Consegui com 1 jndi, porém com dois a aplicação se perde...

Bom dia, consegui desta forma:

DataSource 1:

@Bean(name = "em_Local")
    @Primary
    public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
        LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();

        em.setDataSource(createH2DataSource());
        em.setPackagesToScan(new String[] { "com.teste.*"});
        em.setPersistenceUnitName("LocalPU");

        JpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
        em.setJpaVendorAdapter(vendorAdapter);
        em.setJpaProperties(additionalProperties());

        return em;
    }

    @Bean(name = "tm_Local")
    @Primary
    public PlatformTransactionManager transactionManager(EntityManagerFactory emf) {
        JpaTransactionManager transactionManager = new JpaTransactionManager();
        transactionManager.setEntityManagerFactory(emf);

        return transactionManager;
    }

    private Properties additionalProperties() {
        Properties properties = new Properties();
        properties.setProperty("hibernate.hbm2ddl.auto", "update");
        properties.setProperty("hibernate.dialect", "org.hibernate.dialect.H2Dialect");
        properties.setProperty("hibernate.connection.driver_class", "org.h2.Driver");

        return properties;
    }

    private DataSource createH2DataSource() {
        JndiDataSourceLookup cxt = new JndiDataSourceLookup();
        DataSource dataSource = cxt.getDataSource("java:/comp/env/LOCALDS");
        return dataSource;
    }

DataSource 2:

@Bean
    @Primary
    JdbcTemplate jdbcTemplate() {
        JndiDataSourceLookup cxt = new JndiDataSourceLookup();
        DataSource dataSource = cxt.getDataSource("java:/comp/env/TESTEDS2");

        return new JdbcTemplate(dataSource);
    }
