xml响应不起作用,但是json在使用Jersey的Rest Api运行

这是我在REST API上使用球衣的第一个程序。当我尝试以XML格式返回响应时,我的其余API给了我Error code 500,但对于JSON来说却可以正常工作。

有人可以告诉我我在做什么错吗?

控制台中没有显示错误。

    public class MyResource {
    @GET
    @Produces(MediaType.TEXT_PLAIN)
    public String getIt() {
        return "Got it!";
    }
    @GET
    @Produces(MediaType.APPLICATION_XML)
    @Path("/cust")
    public Customer getCust() {
        Customer cus= new Customer();
        cus.setName("john");
        cus.setId(1);
        cus.setAddress("india");
        return cus;
    }
    @GET
    @Path("/test/order")
    @Produces({MediaType.APPLICATION_JSON,MediaType.APPLICATION_XML})
    public Order getOrder() {
        List<Order> o =new ArrayList<Order>();
        Order ord=new Order();
        ord.setCost(0);
        ord.setProductID(0);
        ord.setQuantity(0);
        ord.setShippingAddress("abcd");
        o.add(ord);

        return ord;
    }


}

    package in.octalian.mobileservice.model;

     import javax.xml.bind.annotation.XmlRootElement;

         @XmlRootElement
     public class Customer {

    private int id;
    private String name ;
    private String address;

    public Customer() {}

    public Customer(int id,String name,String address) {
        this.id=id;
        this.name=name;
        this.address=address;
    }

    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;

    public String getName() {

    public String getAddress() {

    public void setAddress(String address) {

答案 0 :(得分:1)

问题是您试图访问URI newlist = [str(s) for s in a] ,但是您的代码声明为/cus。因此,您应该使用@Path("/cust")

第二,如果在控制台中由于某些错误而没有日志记录,那么您可以在调试模式下运行服务器(对我来说是Apache-tomcat)

答案 1 :(得分:0)

此外,您需要在请求中添加具有预期结果格式类型的标头“ Accept”。如果未指定,将以第一个出现为准。
