我有一个 JAX-RS Jersey WebService，我试图接受 XML 数据（或 JSON）并返回String显示传递的记录总数的响应。

这是我的服务代码：

@Path("customers")
@Singleton
public class CustomersResource {
...
    @POST
    @Path("addall")
    @Produces("text/html")
    @Consumes(javax.ws.rs.core.MediaType.APPLICATION_XML)
    public String addCustomers(List<Customer> customerList) {
        return "success : received " + customerList.size() ;
    }
    ...
}

这是我的客户代码：

public static void main(String[] args) {
    Client client = Client.create();

    WebResource webresource = client.resource( "http://localhost:8080/restdemo/services/customers/addall");

    String input  = "<customerList><customer><name>name1</name></customer><customer><name>name2</name></customer></customerList>";
    String response = webresource.type("application/xml").post( String.class, input );
    System.out.println(response);
}

错误：

Exception in thread "main" com.sun.jersey.api.client.ClientHandlerException: com.sun.jersey.api.client.ClientHandlerException: A message body writer for Java type, class java.util.ArrayList, and MIME media type, application/json, was not found

    ... 5 more

我将不胜感激任何帮助或指向任何可能有用的示例代码。

this is a sample which demostrates required functionality: http://search.maven.org/remotecontent?filepath=com/sun/jersey/samples/jaxb/1.12/jaxb-1.12-project.zip

Jersey User Guide should be useful for you as well.
