我已经定义了RestController（下面的示例代码）。我正在从request参数读取json正文。从我的服务中，我正在调用其他应用程序的另一个Rest端点。我收到“ java.lang.IllegalStateException：已连接”
def processPostRequest(request: HttpServletRequest): ResponseEntity[String] ={
val requestURI = request.getRequestURI
val customURI = requestURI.substring("/abc/xyz".size)
val queryString = request.getQueryString
val queryParameters = extractQueryParameters(queryString)
val httpMethod = request.getMethod.toLowerCase
val inputStream = request.getInputStream
val requestBody = IOUtils.toString(inputStream)
val response = Service.processGraphRequest(customURI,httpMethod,queryParameters, requestBody)
new ResponseEntity[String](response,HttpStatus.OK)
}
我收到以下异常。 java.lang.IllegalStateException：已连接 在sun.net.www.protocol.http.HttpURLConnection.setRequestProperty（HttpURLConnection.java:3071）〜[？：1.8.0_152] 在org.glassfish.jersey.client.internal.HttpUrlConnector.setOutboundHeaders（HttpUrlConnector.java:421）〜[jersey-client-2.22.1.jar :?] 在org.glassfish.jersey.client.internal.HttpUrlConnector.access $ 100（HttpUrlConnector.java:96）〜[jersey-client-2.22.1.jar :?] 在org.glassfish.jersey.client.internal.HttpUrlConnector $ 4.getOutputStream（HttpUrlConnector.java:384）〜[jersey-client-2.22.1.jar :?] 在org.glassfish.jersey.message.internal.CommittingOutputStream.commitStream（CommittingOutputStream.java:200）〜[jersey-common-2.22.1.jar :?] 在org.glassfish.jersey.message.internal.CommittingOutputStream.commitStream（CommittingOutputStream.java:194）〜[jersey-common-2.22.1.jar :?] 在org.glassfish.jersey.message.internal.CommittingOutputStream.commit（CommittingOutputStream.java:262）〜[jersey-common-2.22.1.jar :?] 在org.glassfish.jersey.message.internal.OutboundMessageContext.commitStream（OutboundMessageContext.java:816）〜[jersey-common-2.22.1.jar :?] 在org.glassfish.jersey.client.ClientRequest.writeEntity（ClientRequest.java:545）〜[jersey-client-2.22.1.jar :?] 在org.glassfish.jersey.client.internal.HttpUrlConnector._apply（HttpUrlConnector.java:388）〜[jersey-client-2.22.1.jar :?] 在org.glassfish.jersey.client.internal.HttpUrlConnector.apply（HttpUrlConnector.java:285）〜[jersey-client-2.22.1.jar :?] 在org.glassfish.jersey.client.ClientRuntime.invoke（ClientRuntime.java:255）〜[jersey-client-2.22.1.jar :?] 在org.glassfish.jersey.client.JerseyInvocation $ 1.call（JerseyInvocation.java:684）〜[jersey-client-2.22.1.jar :?] 在org.glassfish.jersey.client.JerseyInvocation $ 1.call（JerseyInvocation.java:681）〜[jersey-client-2.22.1.jar :?] 在org.glassfish.jersey.internal.Errors.process（Errors.java:315）〜[jersey-common-2.22.1.jar :?] 在org.glassfish.jersey.internal.Errors.process（Errors.java:297）〜[jersey-common-2.22.1.jar :?] 在org.glassfish.jersey.internal.Errors.process（Errors.java:228）〜[jersey-common-2.22.1.jar :?] 在org.glassfish.jersey.process.internal.RequestScope.runInScope（RequestScope.java:444）〜[jersey-common-2.22.1.jar :?] 在org.glassfish.jersey.client.JerseyInvocation.invoke（JerseyInvocation.java:681）〜[jersey-client-2.22.1.jar：？]
有人可以帮助我解决问题吗？
