java - 使用 JNDI + Weblogic 的 Hibernate 数据源

Question

我正在尝试使用 Java DataSource 连接到我的数据库。我正在使用 Weblogic 12c 和 Hibernate 来实现这一点。我的 web.xml 文件包含以下资源定义:

    <resource-ref>
        <res-ref-name>jdbc/Microtek</res-ref-name>
        <res-type>javax.sql.DataSource</res-type>
        <res-auth>Container</res-auth>
    </resource-ref>

此外，我的 weblogic.xml 包含以下内容:

    <wls:resource-description>
        <wls:res-ref-name>jdbc/Microtek</wls:res-ref-name>
        <wls:jndi-name>microtek</wls:jndi-name>
    </wls:resource-description>

在我的 Hibernate 配置文件 (hibernate.cfg.xml) 中，我设置了以下属性:

      <property name="hibernate.connection.datasource">jdbc/Microtek</property>
      <property name="hibernate.connection.pool_size">10</property>
      <property name="show_sql">false</property>
      <property name="dialect">org.hibernate.dialect.SQLServerDialect</property>
      <property name="hibernate.hbm2ddl.auto">create</property>
      <property name="javax.persistence.validation.mode">none</property>

此外，在 META-INF 目录中，我创建了一个名为 context.xml 的 XML 文件，其中包含以下内容:

<?xml version="1.0" encoding="UTF-8"?>
<Context>
    <ResourceLink global="jdbc/Microtek" name="jdbc/Microtek" type="javax.sql.DataSource"/>
</Context>

最后，这是我得到的异常:

    at org.hibernate.connection.DatasourceConnectionProvider.configure(DatasourceConnectionProvider.java:75)
    ... 8 more

这是我第一次使用 JNDI 连接到数据源，所以我可能会遗漏一些东西。非常感谢所有想法和建议。

更新:按照其他人的建议进行更改后，我现在遇到以下异常:

Answer 1

您没有为您的数据源定义连接工厂，代码中是这样的:

environment.put("java.naming.factory.initial", "weblogic.jndi.WLInitialContextFactory"); 

或者在 hibernate.cfg.xml 中:

<property name="jndi.class">weblogic.jndi.WLInitialContextFactory</property>

在 weblogic 中，您可以根据需要配置连接工厂，WLInitialContextFactory 是默认设置。
