java - CXF JAXRS - 如何 POST 多个参数

Question

如何在 POST 请求的请求正文中发送多个参数？

@POST
@Consumes("multipart/form-data")
@Produces("application/json")
public String addForm1(@FormParam("i1") Integer i1, @FormParam("i2") Integer i2);

以上代码返回 HTTP 415。

替换 @FormParam与 @Multipart结果 Resource method has more than one parameter representing a request body报错，如下图。

SEVERE: Resource method service.rs.TestService.postData2 has more than one parameter representing a request body
Exception in thread "main" org.apache.cxf.jaxrs.client.ClientWebApplicationException: Resource method service.rs.TestService.postData2 has more than one parameter representing a request body
at org.apache.cxf.jaxrs.client.ClientProxyImpl.reportInvalidResourceMethod(ClientProxyImpl.java:546)
at org.apache.cxf.jaxrs.client.ClientProxyImpl.getParametersInfo(ClientProxyImpl.java:214)
at org.apache.cxf.jaxrs.client.ClientProxyImpl.invoke(ClientProxyImpl.java:138)
at $Proxy20.postData2(Unknown Source)
at service.TestServiceClient.main(TestServiceClient.java:82)

此外，我需要做什么才能传递多个复杂类型，例如 List<Map<String, String>>' or 'List<MyNestedCustomObject>在 POST 方法中？我可以使用 JAXB 传递此类参数并用 @XmlJavaTypeAdapter 注释，但我想这在传递多个参数的情况下不起作用？我是否需要定义自己的消息正文读者和作者？任何示例代码都会很有用。

谢谢

我想出了一个方法来做到这一点(见下面的代码)。但是，如果您知道更好的方法，最好不使用“附件”的概念，而是直接使用 jaxrs:client 而不是 WebClient，请告诉我。

服务:

@POST 
@Path("/postdata3") 
@Consumes("multipart/mixed") 
@Produces("application/json") 
public String postData3(@Multipart(value = "testItem1", type = "application/json") TestItem t1, 
    @Multipart(value = "testItem2", type = "application/json") TestItem t2 
    ); 

客户:

    WebClient client = WebClient.create("http://myserver/services/test/postdata3"); 
    client.type("multipart/mixed").accept("application/json"); 
    List<Attachment> atts = new LinkedList<Attachment>(); 
    atts.add(new Attachment("testItem1", "application/json", t1)); 
    atts.add(new Attachment("testItem2", "application/json", t2)); 
    javax.ws.rs.core.Response s = client.postCollection(atts, Attachment.class); 
    System.out.println(s.getStatus());
