我已经设置了一个Spring Boot(v1.1.9)应用程序来部署为WAR文件。而且我正在尝试将此Web应用程序与现有的数据服务模块(作为Maven依赖项添加)集成。
尝试部署的环境: WebSphere Application Server 8.5.5.4
我面临的问题是,当尝试在依存数据服务模块中按以下方式查找JNDI数据源( jdbc / fileUploadDS )时,应用程序启动失败。
@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"); } }
我的Spring Boot配置:
@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<SampleApplication> 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(); } }
请注意,我能够成功查找props / FileUploadProperties。但是无法对数据源执行相同的操作。
我的疑问是它正在尝试加载 Embedded WebApplicationContext ,这不是我想要的。

我在这里想念什么?即使当我尝试在SampleApplication.java中显式定义dataSource bean方法(如下所示)时,它也会失败,并显示相同的错误。
@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(); }
我提到了这一点,并说我们需要在servlet容器上设置enableNaming()?我可以对非嵌入式Web应用程序上下文执行类似的操作吗?还是纯粹是WAS 8.5问题?
您需要在中具有jdbc/fileUploadDS名称的资源引用web.xml。并确保在安装过程中或通过ibm-web- bnd.xml文件将其绑定到实际的数据源名称。
jdbc/fileUploadDS
web.xml
ibm-web- bnd.xml
中的定义web.xml:
<resource-ref> <description /> <res-ref-name>jdbc/fileUploadDS</res-ref-name> <res-type>javax.sql.DataSource</res-type> <res-auth>Container</res-auth> <res-sharing-scope>Shareable</res-sharing-scope> </resource-ref>
如果您不想使用web.xml,那么在普通的Java EE应用程序中,您可以在Web组件(Servlet,过滤器)中添加以下类注释:
@Resource(name="jdbc/fileUploadDS", type=javax.sql.DataSource.class, lookup="jdbc/fileUploadDS")
但我不是Spring-boot专家,所以不知道它是否可行或是否可行。
