我在春天有一个应用程序,在JBOSS 7.1上运行数据库oracle.
我想测试我的服务层bean只是运行junit测试.
在我的spring上下文中,我使用了像这样的jndi数据源：

<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
    <property name="jndiName" value="jboss/datasources/myDatasource" />
    <property name="resourceRef" value="true"/>
</bean>

当我运行加载spring上下文测试的junit测试时,我收到一个异常,例如：

java.lang.IllegalStateException: Failed to load ApplicationContext
    at org.springframework.test.context.TestContext.getApplicationContext(TestContext.java:157)
    at org.springframework.test.context.support.DependencyInjectionTestExecutionListener.injectDependencies(DependencyInjectionTestExecutionListener.java:109)
...
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [context.xml]: Invocation of init method failed; nested exception is javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file:  java.naming.factory.initial
    at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1455)

如何在我的测试中注入JNDI数据源而不更改jboss中的上下文？

解决方法:

根据this帖子,或this伟大的博客文章,我发现了三种方法来解决我的问题,只需在你的JUnitTest类中创建BeforeClass方法.

我发布给社区：

– 解决方案1
这个解决方案需要catalina.jar和类路径中的oracledriver：

@BeforeClass
public static void setUpClass() throws Exception {
    try {
        System.setProperty(Context.INITIAL_CONTEXT_FACTORY, "org.apache.naming.java.javaURLContextFactory");
        System.setProperty(Context.URL_PKG_PREFIXES, "org.apache.naming");            
        InitialContext ic = new InitialContext();

        ic.createSubcontext("jboss");
        ic.createSubcontext("jboss/datasources");
        ic.createSubcontext("jboss/datasources/myDatasource");

        OracleConnectionPoolDataSource ds = new OracleConnectionPoolDataSource();
        ds.setURL("jdbc:oracle:thin:@xxxxx:1521:xxxxx");
        ds.setUser("myUserid");
        ds.setPassword("myPass");

        ic.rebind("jboss/datasources/myDatasource", ds);
    } catch (NamingException ex) {
        ex.printStackTrace();
    }
}

如果你使用maven,你可以放入你的pom：

<dependency>
    <groupId>org.apache.tomcat</groupId>
    <artifactId>catalina</artifactId>
    <version>6.0.37</version>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>com.oracle</groupId>
    <artifactId>ojdbc6</artifactId>
    <version>11.2.0.3.0</version>
    <scope>test</scope>
</dependency> 

– 解决方案2
此解决方案需要在类路径中使用commons-dbcp：

@BeforeClass
public static void setUpDataSource() throws Exception {
    try {
        SimpleNamingContextBuilder builder = new SimpleNamingContextBuilder();
        DriverAdapterCPDS cpds = new DriverAdapterCPDS();
        cpds.setDriver("oracle.jdbc.OracleDriver");
        cpds.setUrl("jdbc:oracle:thin:@xxxxx:1521:xxxxx");
        cpds.setUser("myUsername");
        cpds.setPassword("myPass");

        SharedPoolDataSource dataSource = new SharedPoolDataSource();
        dataSource.setConnectionPoolDataSource(cpds);
        dataSource.setMaxActive(10);
        dataSource.setMaxWait(50);
        builder.bind("jboss/datasources/myDatasource", dataSource);
        builder.activate();
    } catch (NamingException ex) {
        ex.printStackTrace();
    }
}

在你的pom：

<dependency>
    <groupId>commons-dbcp</groupId>
    <artifactId>commons-dbcp</artifactId>
    <version>1.4</version>
    <scope>test</scope>
</dependency>

– 解决方案3
此解决方案使用Oracle Driver中包含的OracleConnectionPoolDataSource：

@BeforeClass
public static void setUpDataSource() throws Exception {
    try {
        SimpleNamingContextBuilder builder = new SimpleNamingContextBuilder();

        OracleConnectionPoolDataSource ds = new OracleConnectionPoolDataSource();
        ds.setURL("jdbc:oracle:thin:@xxxxx:1521:xxxxx");
        ds.setUser("myUsername");
        ds.setPassword("myPass");           

        builder.bind("jboss/datasources/myDatasource", ds);
        builder.activate();
    } catch (NamingException ex) {
        ex.printStackTrace();
    }
}
