我正在尝试将多个实体传递给 Web 服务方法.web服务方法有两个pojo实体类型参数.我只能将一个实体发布到 Web 服务方法.我无法将多个实体发布到 Web 服务方法.

I am trying to pass multiple entities to the web service method. The web service method has two parameters of pojo entity type. I am able to post only one entity to the web service method. I am unable to post multiple entities to the web service method.

Server side code: @POST @Path("/test") @Produces(MediaType.APPLICATION_XML) @Consumes(MediaType.APPLICATION_XML) public void testMethod(Emp emp, Student stud){ ... } Client side code: ... ... Emp emp = new Emp; Student stud = new Student(); ClientResponse response = resource.type(MediaType.APPLICATION_XML).entity(emp).entity(stud).post(ClientResponse.class);

推荐答案

一个请求只能有一个实体主体，这就是限制的原因.我能想到的唯一选择是使用 multipart request，你可以有多个身体部位.

A request can only have one entity body, that's why the restriction. The only option I can think of is to use multipart request, where you can have multiple body parts.

示例服务器端

@Path("multipart") public class MultipartResource { @POST @Consumes(MediaType.MULTIPART_FORM_DATA) public Response doPost(@FormDataParam("emp") Emp emp, @FormDataParam("student") Student student) { StringBuilder builder = new StringBuilder(); builder.append("Emp:").append(emp.name).append(" "); builder.append("Student:").append(student.name).append(" "); return Response.ok(builder.toString()).build(); } public static class Student { public String name; } public static class Emp { public String name; } }

客户端

public class Main { public static void main(String[] args) throws Exception { Client client = Client.create(); Emp emp = new Emp(); emp.name = "pee"; Student stu = new Student(); stu.name = "skillet"; FormDataMultiPart multipart = new FormDataMultiPart() .field("emp", emp, MediaType.APPLICATION_JSON_TYPE) .field("student", stu, MediaType.APPLICATION_JSON_TYPE); final String url = "localhost:8080/api/multipart"; String response = client.resource(url).type(MediaType.MULTIPART_FORM_DATA_TYPE) .post(String.class, multipart); System.out.println(response); } }

结果:

Emp:小便学生:煎锅

Emp:pee Student:skillet

多部分支持的泽西依赖关系.

Jersey dependency for multipart support.
