jndi-name屬性覆蓋 - JUnit - Spring - Struts集成測試

Question

我正在嘗試使用JUnit，Struts2，Spring，JPA/Hibernate編寫集成測試。

該應用程序在WebSphere中正常工作。集成測試在WebSphere之外運行。

struts2-junit-plugin和spring-struts插件都被使用。我的測試課程延伸StrutsSpringTestCase。

這是在測試方法的示例代碼：

ActionProxy proxy = getActionProxy("custSearch"); 
assertNotNull(proxy); 

它加載struts.xml中，applicationContext.xml中和jpaContext.xml。

在jpaContext.xml中，我有以下條目。

<bean id="dsSQLServer" class="org.springframework.jndi.JndiObjectFactoryBean" p:jndi-name="${sql.jndi.name}"/> 

sql.jndi.name來自屬性文件並在WebSphere中設置。

我去了屬性文件，並用完整的jndi網址替換了本地的jndi網址，這是我從執行websphere的dumpNamespaces.bat中得到的。這就像

MycomnameNode01Cell/nodes/C1A-mYNode/servers/mYSrv/jdbc/sql_src 

但是，當我從eclipse運行JUnit測試用例時，我得到以下異常。

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSourceSQLServer' defined in URL [file:/C:/workspace/context/jpaContext.xml]: Invocation of init method failed; nested exception is javax.naming.NoInitialContextException: Failed to create InitialContext using factory specified in hashtable

問題：

1. 應的JNDI URL會有所不同？是否可以指定完整的URL，如iiop：localhost：/？
2. 是否可以覆蓋@BeforeClass方法中的jndi-name設置或使用靜態初始化程序？因爲，上面的JNDI URL提供者URL丟失。

Answer 1

JNDI上下文通常由您的應用服務器（Websphere）提供。當您從Websphere外部運行測試時，您將無法訪問本地JNDI。我看到3個解決方案...

1. 確保您連接到遠程JNDI

   你應該在@BeforeClass方法初始化您的訪問屬性：

   Hashtable env = new Hashtable(); 
   env.put(Context.PROVIDER_URL, "iiop://server:2809"); 
   env.put(Context.INITIAL_CONTEXT_FACTORY,"com.ibm.websphere.naming.WsnInitialContextFactory"); 
   Context ctx = new InitialContext(env); 
   

   這樣你將能夠訪問遠程JNDI，但數據源不應被序列化。它不能被遠程轉移。

2. 設置本地JNDI

   春天提供可在@BeforeClass方法被用來建立一個本地JNDI，並用手工填寫的數據源它SimpleNamingContextBuilder class

3. 不要加載jpaContext.xml文件

   創建另一個將提供dsSQLServer bean但不訪問JNDI的文件。A SimpleDriverDataSource可能是完美的。

我的首選解決方案是＃3。
