Java：JAX-WS Mapping [英] Java: JAX-WS Mapping

问题描述

我正在使用JAX-WS进行Web服务。

I am using JAX-WS for web services.

每当我使用char作为方法参数时，我将其作为xsd中的unsignedShort（Focus on weatherLetter）。

Whenever I use a char as a method parameter, I am getting it as an unsignedShort in the xsd (Focus on weatherLetter).

以下是声明：

@WebMethod
public boolean setWXtatus(
        @WebParam(name = "weatherLetter") char weatherLetter,
        @WebParam(name = "weatherDigit") int weatherDigit,
        @WebParam(name = "cloudCover") int cloudCover,
        @WebParam(name = "cloudBaseInHundredsOfFeet") int cloudBaseInHundredsOfFeet,
        @WebParam(name = "pressureInHg") int pressureInHg,
        @WebParam(name = "visibilityInKm") int visibilityInKm,
        @WebParam(name = "windSpeed") int windSpeed,
        @WebParam(name = "windDirection") int windDirection,
        @WebParam(name = "lastUpdateHour") int lastUpdateHour,
        @WebParam(name = "lastUpdateMin") int lastUpdateMin
) 

这是我得到的类型映射：

Here is the type mappings I get:

<xs:complexType name="setWXStatus">
<xs:sequence>
<xs:element name="weatherLetter" type="xs:unsignedShort" minOccurs="0"/>
<xs:element name="weatherDigit" type="xs:int"/>
<xs:element name="cloudCover" type="xs:int"/>
<xs:element name="cloudBaseInHundredsOfFeet" type="xs:int"/>
<xs:element name="pressureInHg" type="xs:int"/>
<xs:element name="visibilityInKm" type="xs:int"/>
<xs:element name="windSpeed" type="xs:int"/>
<xs:element name="windDirection" type="xs:int"/>
<xs:element name="lastUpdateHour" type="xs:int"/>
<xs:element name="lastUpdateMin" type="xs:int"/>
</xs:sequence>
</xs:complexType>

如何将weatherLetter生成为Char或1个字符串或其他内容？

How can I get weatherLetter to generate as a Char or 1 Letter String or something?

推荐答案

更新：

一种方法是XSD（如果你首先签约），例如直接添加 XSD限制，例如

One way to do this is the in XSD (if you do contract first) e.g. add an XSD Restriction to it directly, e.g.

<xs:element name="singleChar">
  <xs:simpleType>
    <xs:restriction base="xs:string">
      <xs:length value="1"/>
    </xs:restriction>
  </xs:simpleType>
</xs:element>

但我认为问题是最后合约（例如编写代码，生成XSD，反之亦然）

But I think the question is on contract last (e.g. write code that generates the XSD, not vice versa)

据我所知，这在JAX-WS或JAXB中尚不支持（但是一个很好的增强请求）

This is not yet supported in JAX-WS or JAXB, as far as I know (but a nice enhancement request)

来源：

JAX-WS和JAXB不支持代码生成来自XSD的限制（例如xsd：restriction）
http://old.nabble.com/Does-jaxb-2.1-enforce-xs:restriction-td21348458.html

JAX-WS and JAXB don't have support for code generation for restrictions from XSD (e.g. xsd:restriction) http://old.nabble.com/Does-jaxb-2.1-enforce-xs:restriction-td21348458.html

原因是其他方向（通过注释产生限制）也不受支持

The reason is that the other direction (generating restrictions by Annotation), is not supported too

解决方法：

看看这个： http://download.oracle .com / docs / cd / E17802_01 / webservices / webservices / docs / 1.5 / tutorial / doc / JAXBUsing4.html

还有这个问题：

JAX-WS和Joda-Time？

没有做到你想要的，但让你更近一点

Not doing exactly what you want, but getting you a little bit closer

我不认为你可以将它限制为1个字符串任何其他方式，一个char确实是一个无符号的short，并且最接近你可以限制为1Stringchar。

I don't think you can have it limited to 1 char any other way, a char is indeed an unsigned short, and the closest thing you can to limiting to 1 "String" char.

如果您使用字符串，您将允许无限制的字符。并且 @WebParam 没有用于限制长度的API

If you use a String, you will allow unlimited chars. and @WebParam doesn't have an API to limit length

实际上我没有看到使用JAX-WS完全做XSD限制的方法，但我可能错了

Actually I didn't see a way to do XSD restrictions at all using JAX-WS, but I may be wrong
