本文介绍了Spring Boot JNDI数据源查找失败-在上下文“ java：”中找不到名称comp / env / jdbc的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我已经设置了一个Spring Boot（v 1.1.9）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集成（作为maven依赖项添加）。



尝试部署的环境： WebSphere Application Server 8.5.5.4



我面临的问题是尝试查找JNDI dataSource时应用程序启动失败（ jdbc /在相关数据服务模块中如下所示。

  @Configuration 
 @Profile（ prod ）
公共类JndiDataConfig实现了DataConfig {
 
 @Bean 
 public DataSource dataSource（）引发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。*，演示}）
 @EnableAutoConfiguration（exclude = {HibernateJpaAutoConfiguration.class，DataSourceAutoConfiguration.class}）
公共类SampleApplication扩展了SpringBootServletInitializer {
 
 public static void main（String [] args） {
 SpringApplication.run（applicationClass，args）; 
} 
 
 @Override 
受保护的SpringApplicationBuilder configure（SpringApplicationBuilder application）{
 return application.sources（applicationClass）; 
} 
 
 private static Class< SampleApplication> applicationClass = SampleApplication.class; 
 
 @Bean 
公共静态属性fileUploadJndiProperties（）引发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，我能够查找道具/ FileUploadProperties成功。但是无法对数据源执行相同操作。



我的疑问是它正在尝试加载不是我想要的 EmbeddedWebApplicationContext 。 / p>

我在这里想念什么？甚至当我尝试在SampleApplication.java中显式定义dataSource bean方法时，如下所示，它也会失败，并出现相同的错误。

  @Bean 
公共静态数据源dataSource（）抛出NamingException {
 JndiObjectFactoryBean jndiFactoryBean = new JndiObjectFactoryBean（）; 
 jndiFactoryBean.setJndiName（ java：comp / env / jdbc / fileUploadDS）;

 jndiFactoryBean.setLookupOnStartup（true）; 
 jndiFactoryBean.setResourceRef（true）; 
 jndiFactoryBean.afterPropertiesSet（）; 
 return（DataSource）jndiFactoryBean.getObject（）; 
}

我提到此，它说我们需要在servlet容器上设置enableNaming（）吗？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？

解决方案

您需要使用 jdbc /获得资源引用 web.xml 中的fileUploadDS 名称。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。



web.xml 中的定义：

 < resource-ref> 
<说明/> 
< res-ref-name> jdbc / fileUploadDS< / res-ref-name> 
< res-type> javax.sql.DataSource< / res-type> 
< res-auth>容器< / res-auth> 
< res-sharing-scope> Shareable< / res-sharing-scope> 
< / resource-ref>

如果您不想使用 web.xml ，然后在普通的Java EE应用程序中，您只需在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）

但是我不是Spring-boot专家，所以不知道它是否可以工作。


I have setup a spring boot (v 1.1.9) application to deploy as a WAR file. And I'm trying to integrate this web application with an existing data service module (added as a maven dependency).

Environment trying to deploy: WebSphere Application Server 8.5.5.4

The issue I'm facing is an application start-up failure when try to look-up a JNDI dataSource (jdbc/fileUploadDS) as below within the dependent data service module.

@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");
    }

}

My Spring Boot configuration:

@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();
    }

}

Note that I'm able to lookup props/FileUploadProperties successfully. But failing to do the same for a datasource.

My doubt is it is trying to load a EmbeddedWebApplicationContext which is not what I want.

The stack trace is:

What am I missing here? Even when I try to explicitly define the dataSource bean method in SampleApplication.java like below it fails with the same error.

@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();
    }

I referred this and it says we need to set enableNaming() on servlet container? Can I do something similar for non-embedded web application context? Or is it purely a WAS 8.5 issue??

解决方案

You need to have resource reference with jdbc/fileUploadDS name in your web.xml. And make sure it is bound to actual datasource name during installation or via ibm-web-bnd.xml file.

Definition in 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>

If you dont want to use web.xml, then in normal Java EE app you could just add in web component (servlet, filter) the following class annotation:

@Resource(name="jdbc/fileUploadDS", type=javax.sql.DataSource.class, lookup="jdbc/fileUploadDS")

but I'm not Spring-boot expert, so don't know, if it will work or is possible there.
