Zuul未引发预期的异常

Question

我抛出了一个ZuulRuntimeException，并编写了一个测试用例来验证它，但它抛出了另一个。

代码：

public String extractCdsid(String accessToken) {
ObjectMapper objectMapper = new ObjectMapper();
String cdsid = "";
try {
String payload = JwtHelper.decode(accessToken).getClaims();
cdsid = objectMapper.readTree(payload).get("upn").textValue();
} catch (NullPointerException e) {      
ZuulException ex = new ZuulException(
"Token does not contain upn. Please send a valid that contains upn(cdsid)", 401, "");
throw new ZuulRuntimeException(ex);     
} }

测试用例：

@Test(expected = ZuulRuntimeException.class)
public void getPrincipalHeader_withAuthorizationHeaderNotContainUpn_returnsException(){
// mock
MockHttpServletRequest req = new MockHttpServletRequest();
req.addHeader("Authorization", "sendingtokenthatdoesnotcontainupn");
// run
tokenParser.getPrincipalHeader(req);        
}

我得到

我遇到了同样的问题，我添加了

@Before
public void setUp() {
CounterFactory.initialize(new EmptyCounterFactory());
}

工作。多亏了这一点，我摆脱了java.lang.IllegalStateException: CounterFactory not initialized
