Question

请问如何在使用json api执行弹出批处理作业时将文件名作为作业参数传递？

Map<String, String> map = new HashMap<String, String>();

            map.put("jobparameters", "filename="  + UPLOAD_LOCATION + uploadedFile.getFileName() + ".csv");

            RestTemplate rstTpl = new RestTemplate();

            String result = rstTpl.postForObject(url, map, String.class);

从我的工作中访问该文件，例如

<bean id="edivJobFile" class="org.springframework.core.io.FileSystemResource"
    scope="step">
    <constructor-arg value="#{jobParameters[filename]}" />
</bean>

我后来发现用于POST的Spring批处理JSON api（启动作业）允许将作业参数作为POST请求参数（http://docs.spring.io/spring-batch-admin/reference/json.html）传递，例如 jobparameters = filename = myfile.csv，batchCode = 001

jobparameters = filename = myfile.csv，batchCode = 001

所以我后来做了：

MultiValueMap<String, String> mvm = new LinkedMultiValueMap<String, String>();

String fileNameParam = "filename="  +  UPLOAD_LOCATION + "/" + uploadedFile.getFileName();

String batchCodeParaam = "batchCode=" + uploadedFile.getBatchCode();
String companyCodeParam =  "companyCode=" + companyCode;


mvm.add("jobParameters", fileNameParam + "," + batchCodeParaam + "," + companyCodeParam);

RestTemplate rstTpl = new RestTemplate();

String result = rstTpl.postForObject(url, mvm, String.class);

它有效。 @Michael Pralow，spring api由spring batch admin公开，作为监视和启动作业的选项。感谢
