If you need execute console command (curl in this case):
如果您需要执行控制台命令（在这种情况下为 curl）：
Runtime runtime = Runtime.getRuntime();
try {
Process process = runtime.exec("curl -d \"input = a b c d\" 'localhost:8090/jobs?appName=Test40&classPath=fr.aid.cim.spark.JavaWord&sync=true&timeout=1000000000'");
int resultCode = process.waitFor();
if (resultCode == 0) {
// all is good
}
} catch (Throwable cause) {
// process cause
}
UPDATE (according to your comment):Add folowing lines:
更新（根据您的评论）：添加以下行：
System.out.println("is: " + IOUtils.toString(process.getInputStream()));
System.out.println("es: " + IOUtils.toString(process.getErrorStream()));
What is the output? IOUtils can be found here.
输出是什么？IOUtils 可以在这里找到。

You should take look Apache HttpClientlibrary. With HC Fluentcomponent you can write something like:
你应该看看Apache HttpClient库。使用HC Fluent组件，您可以编写如下内容：
Request.Post("http://localhost:8090/jobs?appName=Test40&classPath=fr.aid.cim.spark.JavaWord&sync=true&timeout=1000000000")
.execute().returnContent();
