为什么我在执行POST请求时会得到405方法不允许

Question

我是其他服务的新手。我正在尝试创建一个从客户端接受json字符串的服务。当我使用JQuery调用此服务时，我收到405错误。下面是ws的Java代码：

这是我向JERSEY POST RESTFUL Webservice发布请求的方式。

var orderinfo = {'ordersplitjson': ordersplitjson, 'customer_id': cust_id , 'homedelivery': homedelivery, 'seatnum' :seatnum , 'locationname':location_nam , 'rownum':rownum}; 
var json_data =  JSON.stringify(orderinfo);
        var ajaxcallquery = $.ajax({
            type:'POST',
              dataType: 'jsonp',
             data: json_data,
             contentType: "application/json; charset=utf-8",
            url:url+'/OMS/oms1/orderinsertservice',
            jsonpCallback:'jsonCallback',
            jsonp:false,
            success: function(response) 
            {
            },
            error: function(jqxhr, status, errorMsg) {
            alert('Failed! ' + errorMsg);
        }

        });


 public class OrdersInsertService 
{
    @POST
    @Consumes(MediaType.APPLICATION_JSON)
    @Produces("application/json")
    public String getData(OrderInfo order,@Context HttpServletResponse serverResponse)
    throws JSONException
            {
         serverResponse.addHeader("Access-Control-Allow-Methods", "GET, POST, PUT, DELETE, OPTIONS, HEAD");
            serverResponse.addHeader("Access-Control-Allow-Credentials", "true");
            serverResponse.addHeader("Access-Control-Allow-Origin", "*");
           serverResponse.addHeader("Access-Control-Allow-Headers", "Content-Type,X-Requested-With");
            serverResponse.addHeader("Access-Control-Max-Age", "60");

}
}


package com.util;

public class OrderInfo {

    String ordersplitjson;
    public String getOrdersplitjson() {
        return ordersplitjson;
    }
    public void setOrdersplitjson(String ordersplitjson) {
        this.ordersplitjson = ordersplitjson;
    }
    public String getCustomer_id() {
        return customer_id;
    }
    public void setCustomer_id(String customer_id) {
        this.customer_id = customer_id;
    }
    public String getHomedelivery() {
        return homedelivery;
    }
    public void setHomedelivery(String homedelivery) {
        this.homedelivery = homedelivery;
    }
    public String getSeatnum() {
        return seatnum;
    }
    public void setSeatnum(String seatnum) {
        this.seatnum = seatnum;
    }
    public String getLocationname() {
        return locationname;
    }
    public void setLocationname(String locationname) {
        this.locationname = locationname;
    }
    public String getRownum() {
        return rownum;
    }
    public void setRownum(String rownum) {
        this.rownum = rownum;
    }
    String customer_id;

    String homedelivery;
    String seatnum;

    String locationname;
    String rownum;


}

请有人告诉我如何解决这个问题

我正在使用Jersey 1，当我使用你的课时，它给我一个eclipse中的编译错误，如图中的hwon

Answer 1

（1）dataType: 'jsonp'应为json。摆脱所有jsonp相关的东西。它应该是json。 jsonp将自动更改为GET请求，因此405（方法不允许）。您的资源方法接受POST。

（2）CORS问题。您需要一个过滤器来处理飞行前。如果您使用的是Jersey 1，则可以使用此类

import com.sun.jersey.spi.container.ContainerRequest;
import com.sun.jersey.spi.container.ContainerResponse;
import com.sun.jersey.spi.container.ContainerResponseFilter;

public class CORSFilter implements ContainerResponseFilter {
    @Override
    public ContainerResponse filter(ContainerRequest request,
            ContainerResponse response) {

        response.getHttpHeaders().add("Access-Control-Allow-Origin", "*");
        response.getHttpHeaders().add("Access-Control-Allow-Headers",
                "origin, content-type, accept, authorization");
        response.getHttpHeaders().add("Access-Control-Allow-Credentials", "true");
        response.getHttpHeaders().add("Access-Control-Allow-Methods",
                "GET, POST, PUT, DELETE, OPTIONS, HEAD");

        return response;
    }
}

然后将其注册为

resourceConfig.getContainerResponseFilters().add(new CORSFilter());

使用web.xml，添加此

<init-param>
  <param-name>com.sun.jersey.spi.container.ContainerResponseFilters</param-name>
  <param-value>com.yourpackage.CORSFilter</param-value>
</init-param>

包含Jersey servlet的<servlet>元素
