java - 如何在java-spring应用程序中并行调用多个soap调用

我想在Java中并行执行我的soap请求调用。
我是多线程的新手，没有办法做到这一点。

public List<TB600Model.Response> getTableDesc(final List<TB600Model.Request> requests)
{
    List<TB600Model.Response> responses = new ArrayList<>();
    for (TB600Model.Request request : requests)
    {
        responses.add(
            this.modifyDescription(
                this.getDescription(
                    request.getSite()
                    ,request.getDescType()
                    ,request.getKeyData()
                    ,request.getEffMdy()
                )
                ,request.getDescType()
                ,request.getKeyData()
            )
        );
    }
    return responses;
}

最佳答案

对于Java 8+，请尝试改用以下方法：

requests.parallelStream().forEach(request -> {...});

将代码放入response.add而不是...

对于早期版本：

ExecutorService es = Executors.newFixedThreadPool(10);
List<Response> responses = new ArrayList<>();
for(Request request:  requests){
    Future<Response> future = es.submit(new Callable<Response>() {
        @Override
        public Response call() throws Exception {
           //create your response here and return
        }
    });

    try {
        responses.add(future.get());
    } catch (InterruptedException e) {
        e.printStackTrace();
    } catch (ExecutionException e) {
        e.printStackTrace();
    }
}
