我有一个问题是将请求xml从RestClient发送到Jax Rs。 我接受并使用作为jaxb对象的bean保存了此请求。 但是，每当我发出请求时，服务器都会返回HTTP 400错误请求。

这是我的XML请求。

<trans>
  <rechargephone>0990909</rechargephone>
  <phonetype>GSM</phonetype>
  <amount>10000</amount>
  <useracctid>10100100</useracctid>
  <userpin>111</userpin>
  <quantity>1</quantity>
</trans>

这是我的资源方法

public class AddingTransResource {

@POST
@Path("add")
@Consumes("application/xml")
public Message add(Trans trans) {

    Trans transaction = new Trans();

方法add接受带有JAXB对象的XML参数，在此处为Trans，它也是此XML的根元素。

下面是我的JAXB对象：

@XmlRootElement
public class Trans {

private String rechargephone;
private String phonetype;
private String amount;
private String useracctid;
private String userpin;
private int quantity;

public String getRechargephone() {
    return rechargephone;
}
public void setRechargephone(String rechargephone) {
    this.rechargephone = rechargephone;
}

我创建JAXB对象的方式就是用@XmlRootElement创建一个Java bean。

有人可以建议我如何修复它以及创建JAXB对象的任何想法吗？

3 个答案:

答案 0 :(得分：2)

您可能需要一个XML命名空间声明（xmlns）到根元素声明。

否则，使用web.xml中的以下参数激活Jersey上的详细跟踪：

<init-param>
  <param-name>com.sun.jersey.config.feature.TracePerRequest</param-name>
  <param-value>true</param-value>      
</init-param>

然后，使用以下标头发送您的HTTP请求：

X-Jersey-Trace-Accept=true

答案 1 :(得分：0)

这看起来像你的XML请求有些细节错误...... JAXB和API似乎定义得很好。我建议你尝试两件事：

1）在XML请求中添加一个标头，这将导致以下XML：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<trans>
<rechargephone>0990909</rechargephone>
<phonetype>GSM</phonetype>
<amount>10000</amount>
<useracctid>10100100</useracctid>
<userpin>111</userpin>
<quantity>1</quantity>
</trans>

2）在XmlRootElement中专门添加JAXB对象的名称：

@XmlRootElement(name="trans")

希望它有所帮助。如果没有，请提供所引发异常的进一步日志信息（不仅是HTTP状态400 - 您可以从Tomcat控制台和日志文件中获取该信息）。

答案 2 :(得分：0)

根据其他建议添加xml标题：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

另外，尝试将xmlns声明添加到根元素中，应该与您的包类似：

<trans xmlns="http://www.xsd.your/Package">
...
</trans>
