无法通过wsimport生成的源中具有类路径方案的URL的getResource

问题描述 投票：0回答：1

我正在使用wsimport（jaxws-maven-plugin），并且所生成的源在类路径上查找WSDL文件时存在问题。我将classpath:numberconversion.wsdl用作wsdlLocation，这种wsdlLocation样式可在另一个可以在我的机器上建立OK的项目中工作，但不能在我的最小项目中使用。

这里是main：

import java.math.BigInteger;
import test.wsimport.numberconversion.NumberConversion;

public class Something {
    public static void main(String[] args) {

        Something.class.getResource("classpath:numberconversion.wsdl"); // null - why?
        Something.class.getResource("numberconversion.wsdl"); // null - why?
        Something.class.getClassLoader().getResource("classpath:numberconversion.wsdl"); // null - why?
        Something.class.getClassLoader().getResource("numberconversion.wsdl"); // absolute path to WSDL

        new NumberConversion().getNumberConversionSoap().numberToWords(new BigInteger("42"))); // WebServiceException

    }
}

WebServiceException出现在生成的源中：

NUMBERCONVERSION_WSDL_LOCATION = test.wsimport.numberconversion.NumberConversion.class
        .getResource("classpath:numberconversion.wsdl");
WebServiceException e = null;
if (NUMBERCONVERSION_WSDL_LOCATION == null) {
    e = new WebServiceException(
        "Cannot find 'classpath:numberconversion.wsdl' wsdl. Place the resource correctly in the classpath.");
}

为什么生成的源不起作用？

作为参考，如果您想重现错误，这里是pom.xml和WSDL。

事实证明，classpath:方案是Spring添加的，如果没有Spring在类路径和已初始化上的运行，它将无法正常工作。 （我曾尝试添加与其他项目相同的所有依赖项，但我没有调用它们）。

同时，class.getResource相对于当前路径，而class.getClassLoader().getResource相对于类路径的根。如果以class.getResource开头，则/可以查看类路径的根。

[为了使wsimport生成看起来在类路径的根上的代码，我使用了<wsdlLocation>/numberconversion.wsdl</location>（用/代替classpath:）。
