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

问题描述

我将 JAX-WS 用于 Web 服务.

I am using JAX-WS for web services.

每当我使用 char 作为方法参数时，我都会将它作为 xsd 中的 unsignedShort 获取(关注weatherLetter).

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

声明如下:

@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>

如何让weatherLetter 生成为Char 或1 个字母字符串之类的?

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

推荐答案

更新:

一种方法是在 XSD 中(如果您先签约)，例如直接向其添加 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>

但我认为问题在于合同最后(例如，编写生成 XSD 的代码，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，JAX-WS 或 JAXB 尚不支持此功能(但这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 不支持针对来自 XSD 的限制(例如 xsd:restriction)的代码生成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

原因是另一个方向(通过Annotation产生限制)，也不支持

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

解决方法:

还有这个问题:

JAX-WS 和 Joda-Time?

不是做你想做的，而是让你更接近一点

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

我认为您不能以任何其他方式将其限制为 1 个字符，一个字符确实是一个无符号短整型，并且您可以将其限制为 1 个字符串"字符.

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，您将允许无限字符.并且 @WebParam 没有限制长度的API

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

实际上我根本没有看到使用 JAX-WS 进行 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
