Question

正在开发简单的休息网络服务，并采用球衣框架。写入@POST方法，消耗并生成{MediaType.APPLICATION_JSON,MediaType.APPLICATION_XML}。使用chrome Advance rest客户端调用Web服务。 Webservices正如预期的那样运行以下application / json请求

{"noSave": "Save", "dateCre":"14/12/2014"}

但是对下面的appliation / xml请求收到400个错误请求

<?xml version="1.0" encoding="UTF-8">
<noSave>Save</noSave>
<dateCre>14/12/2014</dateCre>

代码中没有编译错误。感谢您解决以下问题的任何帮助。下面是我写的代码

请求对象：

import java.math.BigDecimal;
import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlType;

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "Creation", propOrder = {

})
public class Creation {

    @XmlElement(required = true)
    protected String noSave;
    @XmlElement(required = true)
    protected String dateCre;

    public String getNoSave() {
        return noSave;
    }

    public void setNoSave(String value) {
        this.noSave = value;
    }

    public String getDateCre() {
        return dateCre;
    }

    public void setDateCre(String value) {
        this.dateCre = value;
    }
}

响应对象：

import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlType;
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "MyResponse", propOrder = {

})
public class MyResponse {

    @XmlElement(required = true)
    protected String resString;
    public String getResString() {
        return resString;
    }
    public void setResString(String value) {
        this.resString = value;
    }
}

休息网络服务：

import javax.validation.Valid;
import javax.ws.rs.Consumes;
import javax.ws.rs.POST;
import javax.ws.rs.PUT;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;

@Path("/create")
public class CreateRequest {

    @POST
    @Produces({  MediaType.APPLICATION_JSON,MediaType.APPLICATION_XML })
    @Consumes({ MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML })
    public Response createReq( @Valid Creation request)
    {
        System.out.println(" Request "+request.getNoSave());
        MyResponse result = new MyResponse();
        result.setResString(" Created with Number 123");
        return Response.ok(result).build();
    }
}

以下是我在chrome rest客户端

中遇到的错误

我也试过下面的代码

@XmlRootElement(name="Creation")
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "Creation", propOrder = {

})
public class Creation {

以及xml请求下方。但得到同样的错误

<?xml version="1.0" encoding="UTF-8">
<Creation>
    <noSave>NoSave</noSave>
    <dateCre>14/12/2014</dateCre>
</Creation>

显示日志中的

以下错误

javax.xml.bind.UnmarshalException: unexpected element (uri:"", local:"Creation"). Expected elements are <{http://check.com/rrs}Creation>

Answer 1

此

<?xml version="1.0" encoding="UTF-8">
<noSave>Save</noSave>
<dateCre>14/12/2014</dateCre>

不是有效的XML。 XML文档应该只有一个根元素。对于POJO映射，根元素应为<Creation>。所以试试

<?xml version="1.0" encoding="UTF-8"?>
<Creation>
    <noSave>sdfshd</noSave>
    <dateCre>3840389</dateCre>
</Creation>

您还应该在课程中添加@XmlRootElement

@XmlRootElement(name = "Creation")
public class Creation {

MyResponse

相同

@XmlRootElement(name = "MyResponse")
public class MyResponse {

使用XML，您将获得返回

<MyResponse>
    ...
</MyResponse>

没办法解决这个问题。这就是XML的工作原理。

更新

您在xml标头的末尾也缺少?。

<?xml version="1.0" encoding="UTF-8"?>   // See the `?`. You are missing that

虽然甚至不需要标题。只需发送

<Creation>
    <noSave>sdfshd</noSave>
    <dateCre>3840389</dateCre>
</Creation>

我已经测试了这个并且工作正常

Answer 2

可能会尝试将您的请求解析为xml文档。有效的XML文档必须只包含1个根节点。

休息申请/ xml有400个错误请求
