NameNotFound Exception - Spring Boot（LATEST），嵌入式Tomcat，JNDI

时间：2015-10-09 20:23:32

标签： hibernate spring-boot jndi embedded-tomcat-8

我的症状类似于： How to create JNDI context in Spring Boot with Embedded Tomcat Container

我创建了一个github repo来重新创建我的问题：https://github.com/Rkiouak/spring-boot-embedded-tomcat-hibernate-jndi （注意，您可能需要手动添加oracle依赖项，因为oracle阻止将其jar发布到公共maven回购）

克隆回购物，放入其中并使用mvn clean＆amp;＆amp; amp; mvn package＆amp;＆amp; java -jar target / spring-boot-sample-tomcat-jndi-0.1.0-SNAPSHOT.jar将重现NameNotFound execption。

任何人都可以帮助我理解为了使用tomcat 8需要更改哪些配置以及最新的带有jndi的spring-boot版本（可能是hibernate复杂的东西）？

问题的更长描述：

之前答案的解决方案对我没有用，我怀疑新版本中存在依赖问题，或者与hibernate执行jndi查找的方式有关。

但是，我克隆了https://github.com/wilkinsona/spring-boot-sample-tomcat-jndi，将其春季启动依赖关系更新为LATEST，更新了此新版本产生的tomcat包/导入，并从Tomcat 7迁移到Tomcat 8并使其运行。

我怀疑我的问题略有不同，但异常显示是相同的。

我收到的例外是：

我正致力于将传统的Struts应用程序迁移到Spring MVC，最好是使用嵌入式tomcat进行Spring启动。最终我打算将这些jndi资源查找更改为（至少我所知道的）传统定义的数据源，但是此时想要避免这一步骤。

我导入了applicationContext.xml资源：

@Configuration
@ComponentScan
@EnableAutoConfiguration
@ImportResource("classpath:context/applicationContext.xml")
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

    @Bean
    public TomcatEmbeddedServletContainerFactory tomcatFactory() {
        return new TomcatEmbeddedServletContainerFactory() {

            @Override
            protected TomcatEmbeddedServletContainer getTomcatEmbeddedServletContainer(
                    Tomcat tomcat) {
                tomcat.enableNaming();
                return super.getTomcatEmbeddedServletContainer(tomcat);
            }

            @Override
            protected void postProcessContext(Context context) {
                ContextResource resource = new ContextResource();
                ContextResourceLink resourceLink = new ContextResourceLink();
                resource.setName("jdbc/MyDataSource");
                resource.setProperty("global", "jdbc/MyDataSource");
                resource.setType("javax.sql.DataSource");
                resource.setProperty("driverClassName", "oracle.jdbc.driver.OracleDriver");
                resource.setProperty("url", "jdbc:yourDb");
                resource.setAuth("Container");

                context.getNamingResources().addResource(resource);

                resourceLink.setName("jdbc/MyDataSource");
                resourceLink.setType("javax.sql.DataSource");
                resourceLink.setProperty("driverClassName",  "oracle.jdbc.driver.OracleDriver");
                resourceLink.setProperty("url", "jdbc:connectionString");

                context.getNamingResources().addResourceLink(resourceLink);

                System.out.println("\n\n\ncontext naming resources\n"+context.getResourceOnlyServlets()+"\n\n\n");
            }
        };
    }

    @Bean(destroyMethod="")
    public DataSource jndiDataSource() throws IllegalArgumentException, NamingException {
        System.out.println("\n\n\nIn jndiDataSource\n\n\n");
        JndiObjectFactoryBean bean = new JndiObjectFactoryBean();
        bean.setJndiName("java:comp/env/jdbc/MyDataSource");
        bean.setProxyInterface(oracle.jdbc.driver.OracleDriver.class);
        bean.setLookupOnStartup(false);
        bean.afterPropertiesSet();
        return (DataSource)bean.getObject();
    }
}

资源applicationContext.xml引用了一个hibernateContext.xml，它引用了一个hibernate.cfg.xml文件，如下所示：

<hibernate-configuration>
    <session-factory>
        <property name="connection.datasource">java:comp/env/jdbc/MyDataSource</property>
        <property name="dialect">org.hibernate.dialect.Oracle9Dialect</property>
        <property name="show_sql">false</property>
        <property name="format_sql">true</property>
        <property name="hibernate.max_fetch_depth">2</property>
.....

我没有看到

中的println 
@Bean(destroyMethod="")
public DataSource jndiDataSource()...

豆。我确实看到了：

Name = MyDataSource Ignoring unknown property: value of "jdbc/MyDataSource" for "global" property

并认识到这不是一个有效或有用的设置，但这是我尝试过的事情之一。

任何有关识别1）原因和2）解决方案的帮助都将非常感激 - 我之前没有使用过JNDI资源，这个应用程序的背景是WAS。

我已经查看了大多数堆栈溢出问题，这些问题模糊地匹配了spring-boot，hibernate，jndi，未找到的名称以及通过tomcat资源定义文档读取的一些组合，但是还没有找到能够把它拼凑起来......

如果我遗漏了任何

，请告诉我

1 个答案:

答案 0 :(得分：0)

我遇到了同样的问题。我建议首先尝试更改JndiObjectFactory上的jndiName。正如here所解释的那样，它应该是jdbc / myDataSource，而不是java：comp / env / jdbc / myDataSource。看起来注册会自动将资源放在java：comp / env /下。这对我有用。

您还可以在 application.properties

中定义数据源 
spring.datasource.jndi-name=jdbc/myDataSource

而不是在Application类中执行：

@Bean(destroyMethod="")
public DataSource jndiDataSource() {
...
   bean.setJndiName("jdbc/myDataSource");
...
}

要解决我的错误，我还必须使用与您复制的示例不同的依赖项。我从tomcat 8.0.23切换到7.0.56并切换到tomcat-dbcp 7.0.47：

父母pom 

<properties>
    <java.version>1.7</java.version>
    <tomcat.version>7.0.56</tomcat.version>
    <boot.version>1.2.5.RELEASE</boot.version>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <start-class>com.My_App</start-class>
</properties>
