如何测试AsyncRestTemplate
请求并避免java.lang.IllegalStateException: Expectations already declared
例外?对于单个测试用例,异常抛出不一致。
Java.lang.IllegalStateException: Expectations already declared
at org.springframework.util.Assert.state(Assert.java:70)
at org.springframework.test.web.client.SimpleRequestExpectationManager.afterExpectationsDeclared(SimpleRequestExpectationManager.java:47)
at org.springframework.test.web.client.AbstractRequestExpectationManager.validateRequest(AbstractRequestExpectationManager.java:73)
at org.springframework.test.web.client.MockRestServiceServer$MockClientHttpRequestFactory$1.executeInternal(MockRestServiceServer.java:289)
at org.springframework.mock.http.client.MockClientHttpRequest.execute(MockClientHttpRequest.java:94)
at org.springframework.mock.http.client.MockAsyncClientHttpRequest.executeAsync(MockAsyncClientHttpRequest.java:50)
at org.springframework.web.client.AsyncRestTemplate.doExecute(AsyncRestTemplate.java:503)
at org.springframework.web.client.AsyncRestTemplate.execute(AsyncRestTemplate.java:463)
at org.springframework.web.client.AsyncRestTemplate.getForEntity(AsyncRestTemplate.java:217)
at com.company.MainClient.getStatus(MainClient.java:151)
at com.company.MainController.status(MainController.java:88)
该应用程序聚合来自多个下游系统的数据。要求它提出几个请求。一些请求是异步的,后面会处理Future。其他请求通过立即调用asyncRestTemplateResponse.get()
来阻止主线程。
以下测试导致错误:
注意:服务器是
MockRestServiceServer
@Test
public void statusTest() throws Exception {
cServer.expect(once(),requestTo("http://localhost:8080/heartbeat"))
.andRespond(withSuccess(cStatus, MediaType.APPLICATION_JSON));
cpServer.expect(once(),requestTo("http://localhost:8081/status"))
.andRespond(withSuccess(cpStatus, MediaType.APPLICATION_JSON));
tServer.expect(once(),requestTo("http://localhost:3030/check"))
.andRespond(withSuccess(tStatus, MediaType.TEXT_PLAIN));
tServer.expect(once(),requestTo("http://localhost:3031/check"))
.andRespond(withSuccess(tStatus, MediaType.TEXT_PLAIN));
tServer.expect(once(),requestTo("http://localhost:3032/check"))
.andRespond(withSuccess(tStatus, MediaType.TEXT_PLAIN));
mockMvc.perform(get("/status").with(user(USERNAME).password(PASSWORD).roles("T_CLIENT")))
.andDo(print()).andExpect(status().isOk())
.andExpect(jsonPath("$.code").value("200"))
.andExpect(jsonPath("$.appDescription").value("Main Service"))
.andExpect(jsonPath("$.gateways[?(@.responseCode =~ /200/)]").isArray());
//Test without basic auth
mockMvc.perform(get("/status"))
.andDo(print()).andExpect(status().isUnauthorized());
}
根据Eric Pabst上面的说明,https://jira.spring.io/browse/SPR-16132似乎认为这是一个问题。我正在使用Brussels-SR5。我订了 属性4.3.13.RELEASE和问题消失了。
