创建MultipartHttpServletRequest然后获取Exception。我已经创建了HttpServletRequest，但在使用MultipartHttpServletRequest进行转换时，则获得了Exception 我的代码是

public void uploadFileOnLocal(@RequestParam Long caseId, HttpServletRequest request ,HttpServletResponse response) {

MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest) request;

例外是：

   SEVERE: Servlet.service() for servlet [download] in context with path   [/localdownload] threw exception [Request processing failed; nested exception is           java.lang.ClassCastException: org.apache.catalina.connector.RequestFacade cannot be cast to org.springframework.web.multipart.MultipartHttpServletRequest] with root cause
java.lang.ClassCastException: org.apache.catalina.connector.RequestFacade cannot be cast to org.springframework.web.multipart.MultipartHttpServletRequest

Answer 1

您在JSP中的标记可能没有enctype =“multipart / form-data”作为属性，将表单标记为，并且此错误将被删除。例如：

<form method="post" enctype="multipart/form-data">
</form>

根据您的Spring版本，您可能需要正确地进行转换 - 请检查此帖子How to get a MultipartHttpServletRequest from RequestContextHolder?

你需要

node('git && linux') {
    // dome some stuff here
}

stage "Running unit tests for $REVISION"
build job: 'unit-tests', parameters: [[$class: 'StringParameterValue', name: 'REVISION', value: REVISION], [$class: 'StringParameterValue', name: 'REFSPEC', value: REFSPEC]]

stage "Running integration tests $REVISION"
def jobs = [:]
jobs['integration-tests-1']={build job: 'integration-tests-job-1', parameters: [[$class: 'StringParameterValue', name: 'REVISION', value: REVISION], [$class: 'StringParameterValue', name: 'REFSPEC', value: REFSPEC]]}
jobs['integration-tests-2']={build job: 'integration-tests-job-2', parameters: [[$class: 'StringParameterValue', name: 'REVISION', value: REVISION], [$class: 'StringParameterValue', name: 'REFSPEC', value: REFSPEC]]}
jobs['integration-tests-3']={build job: 'integration-tests-job-3', parameters: [[$class: 'StringParameterValue', name: 'REVISION', value: REVISION], [$class: 'StringParameterValue', name: 'REFSPEC', value: REFSPEC]]}

parallel jobs

// Here I would like to add something like
// aggregateDownstream('unit-tests', 'integration-tests-1', 'integration-tests-2', 'integration-tests-3'
