我正在尝试对 struts2 操作进行单元测试（命中一个真实的数据库），但我无法成功连接到数据库。
我是 Spring 新手，项目设置在多个 bean 和 DAO 类中使用 jdbctemplate。
到目前为止，这是我的尝试：
测试类：
public class Test extends StrutsSpringTestCase {
private static final String serverURL = "jdbc:db2://xxxx.xxx.com:----/xxxx";
private static final String username = "xxxxxxx";
private static final String password = "xxxxxxx";
@Override
public String[] getContextLocations() {
SimpleNamingContextBuilder s = new SimpleNamingContextBuilder();
DB2SimpleDataSource db=new DB2SimpleDataSource();
try {
DriverManager.registerDriver( new com.ibm.db2.jcc.DB2Driver() );
} catch (SQLException e2) {
// TODO Auto-generated catch block
e2.printStackTrace();
}
try {
Class.forName("com.ibm.db2.jcc.DB2DataSource");
} catch (ClassNotFoundException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
db.setServerName(serverURL);
db.setPortNumber(----);
db.setUser(username);
db.setPassword(password);
try {
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,
"com.ibm.websphere.naming.WsnInitialContextFactory");
env.put(Context.PROVIDER_URL, "iiop://xxxx.xxx.com:----");
Context ctx = new InitialContext(env);
Context javaCtx = ctx.createSubcontext("jdbc");
javaCtx.bind("xxx", db);
ctx.bind("java:", javaCtx);
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (NamingException e) {
e.printStackTrace();
}
String[] locations = new String[1];
locations[0] = "xxxx.xml";
return locations;
}
public void test() throws Exception {
ActionProxy proxy = getActionProxy("/test");
testAction rd = (testAction) proxy.getAction();
System.out.println(rd.testMethod());
}
}
应用程序上下文.xml：

<constructor-arg>
<ref bean="dataSource" />
</constructor-arg>
</bean>
<bean id="xxxxDao"
class="xxxx">
<property name="jdbcTemplate" ref="jdbcTemplate" />
</bean>
（继续使用其他与 DAO 相关的 bean）。
许多类都依赖于 JdbcTemplate，如下所示，所以我想找到一个包含它的解决方案：
private JdbcTemplate jdbcTemplate;
private String schemaName = "xxxxxx";
private String procedureName = "xxxxxx";
public void setJdbcTemplate(JdbcTemplate jdbcTemplate) {
this.jdbcTemplate = jdbcTemplate;
}
public RDResponseBO browseRD(RDRequestBO rdReqBO) {
SimpleJdbcCall storedProc = new SimpleJdbcCall(jdbcTemplate)
.withSchemaName(schemaName)
.withoutProcedureColumnMetaDataAccess().withProcedureName(
procedureName); .........
我的 applicationContext.xml 包含一个数据源和一个 jndi bean，这有点多余。我不知道是否可以在 JdbcTemplate 中将它们结合起来以使连接成功。
单独使用数据源会导致缺少元数据/jdbc 异常......虽然我想使用 jndiobjectfactorybean 类，但如果不通过服务器运行，bean 不会在 JUnit 中初始化。
我尝试在 jdbctemplate bean 中包含 jndi bean（在调用 simplenamingcontextbuilder 之后），这导致了匹配的构造函数异常。
想法/建议？
PS如果问题格式有点不对，我很抱歉，我也是stackoverflow的新手。
