如何为Spring配置JNDI资源-应用程序？

Question

Spring4 + jpa2.0上的应用程序已部署在websphere8.5.13上

用于持久层的配置使用application.property文件读取用于数据库连接的login \ pass。

有可用的代码，其中使用了application.properties文件：

@Configuration
@EnableTransactionManagement
@EnableJpaAuditing
@EnableJpaRepositories(basePackages = {"data.persistence"})
@PropertySource("classpath:application.properties")
@ComponentScan(basePackages = {"data.persistence", "data.model"})
public class PersistenceConfig {
    private static final String PROP_DATABASE_DRIVER = "db.driver";
    private static final String PROP_DATABASE_URL = "db.url";
    private static final String PROP_DATABASE_USERNAME = "db.username";
    private static final String PROP_DATABASE_PASSWORD = "db.password";
    private static final String PROP_HIBERNATE_DIALECT = "db.hibernate.dialect";
    private static final String PROP_HIBERNATE_SHOW_SQL = "db.hibernate.show_sql";
    private static final String PACKAGE_WITH_JPA_ENTITIES = "ru.sbrf.risks.services.data.persistence";
    private static final String PROP_HIBERNATE_HBM2DDL_AUTO = "db.hibernate.hbm2ddl.auto";
    private static final String DO_NOT_AUDIT_LOCKING_FIELD = "org.hibernate.envers.do_not_audit_optimistic_locking_field";

    @Resource
    private Environment env;

    @Bean
    public DataSource dataSource() {
        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setDriverClassName(env.getRequiredProperty(PROP_DATABASE_DRIVER));
        dataSource.setUrl(env.getRequiredProperty(PROP_DATABASE_URL));
        dataSource.setUsername(env.getRequiredProperty(PROP_DATABASE_USERNAME));
        dataSource.setPassword(env.getRequiredProperty(PROP_DATABASE_PASSWORD));
        log.info("dataSource configured.");
        return dataSource;
    }

    @Bean
    public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
        LocalContainerEntityManagerFactoryBean entityManager = new LocalContainerEntityManagerFactoryBean();
        entityManager.setDataSource(dataSource());
        entityManager.setPackagesToScan(PACKAGE_WITH_JPA_ENTITIES);
        entityManager.setPersistenceProviderClass(HibernatePersistenceProvider.class);
        entityManager.setJpaVendorAdapter(new HibernateJpaVendorAdapter());
        entityManager.setJpaProperties(getHibernateProperties());
        log.info("Entity Manager configured.");
        return entityManager;
    }

    @Bean
    public JpaTransactionManager transactionManager(EntityManagerFactory entityManagerFactory) {
        JpaTransactionManager transactionManager = new JpaTransactionManager();
        transactionManager.setEntityManagerFactory(entityManagerFactory);
        log.info("transactionManager configured.");
        return transactionManager;
    }
}

因此，我需要从application.properties迁移到jdbc / jndi资源，在dataSource（）方法中更改数据库连接的数据源，并在web.xml文件中添加配置：

@Configuration
@EnableTransactionManagement
@EnableJpaAuditing
@EnableJpaRepositories(basePackages = {"data.persistence"})
@PropertySource("classpath:application.properties")
@ComponentScan(basePackages = {"data.persistence", "data.model"})
public class PersistenceConfig {

    private static final String PACKAGE_WITH_JPA_ENTITIES = "data.persistence";

    @Bean
    @Resource(name="jdbc/MYAPP")
    public DataSource dataSource() {
        final JndiDataSourceLookup dsLookup = new JndiDataSourceLookup();
        dsLookup.setResourceRef(true);
        DataSource dataSource = dsLookup.getDataSource("java:comp/env/jdbc/MYAPP");
        return dataSource;
    }

    @Bean
    public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
        LocalContainerEntityManagerFactoryBean entityManager = new LocalContainerEntityManagerFactoryBean();
        entityManager.setDataSource(dataSource());
        entityManager.setPackagesToScan(PACKAGE_WITH_JPA_ENTITIES);
        entityManager.setJpaVendorAdapter(new HibernateJpaVendorAdapter());
        entityManager.setJpaProperties(getHibernateProperties());
        return entityManager;
    }

    @Bean
    public JpaTransactionManager transactionManager(EntityManagerFactory entityManagerFactory) {
        JpaTransactionManager transactionManager = new JpaTransactionManager();
        transactionManager.setEntityManagerFactory(entityManagerFactory);
        return transactionManager;
    }

    //Set properties hibernate
    private Properties getHibernateProperties() {
        Properties properties = new Properties();
        properties.put("hibernate.dialect", "org.hibernate.dialect.OracleDialect");
        properties.put("hibernate.show_sql", "true");
        properties.put("hibernate.hbm2ddl.auto", "update");
        properties.put("org.hibernate.envers.do_not_audit_optimistic_locking_field", false);

        properties.put("verifyServerCertificate", false);
        properties.put("useSSL", false);
        properties.put("requireSSL", false);
        properties.put("useLegacyDatetimeCode", false);
        properties.put("useUnicode", "yes");
        properties.put("characterEncoding", "UTF-8");
        properties.put("serverTimezone", "UTC");
        properties.put("useJDBCCompliantTimezoneShift", true);
        return properties;
    }
}

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
                             http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
         version="3.0">
    <resource-ref>
        <description>Resource reference to my database</description>
        <res-ref-name>jdbc/MYAPP</res-ref-name>
        <res-type>javax.sql.DataSource</res-type>
        <res-auth>Container</res-auth>
        <res-sharing-scope>Shareable</res-sharing-scope>
    </resource-ref>
</web-app>

但是这种方式会引发异常并且无法启动
