java - 模拟无状态 session bean 会给出 javax.naming.NoInitialContextException

Question

有一些类:

 @Stateless   
 public class SomeSimpleBean implements SomeSimpleLocal{

    private static SomeSimpleBean cachedInstance;

    public static SomeSimpleLocal lookup() throws NamingException {
      if (cachedInstance == null) {
        cachedInstance = (SomeSimpleLocal) new InitialContext()
            .lookup(“something”);
    }
    return cachedInstance;
 }
 ...
}

还有另一个类:

public class SomeOtherClass(){

private SomeSimpleLocal getSomeSimpleBean() throws SomeException {

    try {
        return SomeSimpleLocal.lookup();
      } catch (Throwable e) {
        throw new SomeException(“…”, e);
      }
    }

private String generateResponse(String transactionId, String someParameter) throws Exception {

    SomeSimpleBean beanController = getSomeSimpleBean();

    String receivedString = controller.someMethod(transactionId,
        someParameter);
    return receivedString;
    }
    ...

public String giveMeSomeData(){
    ...
  String xxx = generateResponse(a,b);
    ...
    return someString;
   }
 }

在这种情况下是否可以模拟 SomeSimpleBean ？模拟 SomeSimpleBean 给出 javax.naming.NoInitialContextException。

Answer 1

Hashtable<Object, Object> env = new Hashtable<Object, Object>();

InitialContextFactory fact = mock(InitialContextFactory.class);
InitialContextFactoryBuilder builder = mock(InitialContextFactoryBuilder.class);
InitialContext ctx = mock(InitialContext.class);
SomeSimpleBean someSimepleBeanMock = mock(SomeSimpleBean.class);

NamingManager.setInitialContextFactoryBuilder(builder);

when(builder.createInitialContextFactory(env)).thenReturn(fact);
when(NamingManager.getInitialContext(env)).thenReturn(ctx);

when(ctx.lookup("SomeSimpleBean/local")).thenReturn(
        someSimpleBeanMock);
