Groovy - 方法的模糊方法重载

Question

我已经查看了论坛，找到了一些关于这个问题的提示，但没有一个完全符合我的。

我在调用 WSDLParse.parse 方法后得到了这个异常。 顺便说一句，我正在尝试将我的 Groovy 版本 2.2.1 更新到 2.4.3，我错过了什么吗？

感谢您的建议

Ps：这是异常信息，下面你可以找到所有的stacktrace。

groovy.lang.GroovyRuntimeException：方法 com.predic8.schema.Element#setType 的方法重载不明确。 由于以下之间的原型重叠，无法解析为 [null] 调用哪个方法： [类 javax.xml.namespace.QName] [类 groovy.xml.QName]

  groovy.lang.GroovyRuntimeException: Ambiguous method overloading for method com.predic8.schema.Element#setType.
Cannot resolve which method to invoke for [null] due to overlapping prototypes between:

我没有设置元素也没有设置属性。此外，我没有在我的脚本中使用任何 QName 类。 这是我的 groovy 脚本文件->

import groovy.time.BaseDuration.From;
import groovy.util.XmlParser;
import groovy.util.XmlSlurper;
import groovy.xml.MarkupBuilder;
import groovy.xml.XmlUtil;

import java.io.StringWriter;

import com.predic8.wsdl.Definitions;
import com.predic8.wsdl.WSDLParser;
import com.predic8.wstool.creator.RequestTemplateCreator;
import com.predic8.wstool.creator.SOARequestCreator;

class ESBWsdlParser {
    String formTemplate;
    String requestSoapXml;
    public ESBWsdlRequest(String wsdlFile,String operationName) {
        File file = new File(wsdlFile);
        println file.getAbsolutePath();

        WSDLParser parser = new WSDLParser();
        Definitions wsdl = parser.parse(wsdlFile);
        StringWriter writer = new StringWriter();
        SOARequestCreator creator = new SOARequestCreator(wsdl, new RequestTemplateCreator(), new MarkupBuilder(writer));
        //creator.createRequest(PortType name, Operation name, Binding name);
        creator.createRequest(null, operationName, null);
        formTemplate = writer.toString();

    }
    public String resolveName(c){
        String[] arParts = c.name().toString().split("}");
        if(arParts.length > 1){
            return  arParts[1];
        }
        return c.name;
    }

Answer 1

问题是有两个对象兼容和单参数 setType 方法，你用null 调用它。或者更准确地说，你不调用方法，你设置属性，这导致方法调用。

现在在 Groovy 2.4 之前，我们不支持重载情况。调用哪个方法实际上是随机的。换句话说，如果它总是为您的案例调用正确的方法，那么您很幸运。从 Groovy 2.4 开始，Groovy 支持重载的 setter，但这可能会导致 setter 重载导致上述异常的情况。我认为不错的东西，因为它显示了过去可能导致神秘错误的东西。

修复不是那么好...setType((QName) qname)) 而不是属性分配....当然是您选择的 QName 类。你当然可以使用 Keegan 的建议来支持你

编辑：将 setElement 更改为 setType

Answer 2

您可能应该使用ask SOA Membrane 来编辑Element 的

type = getTypeQName(token.getAttributeValue( null , 'type'))

类似

type = (QName) getTypeQName(token.getAttributeValue( null , 'type'))

解决歧义。同时，您可以手动覆盖自己，像这样

@Grab(group='ch.qos.logback', module='logback-classic', version='1.1.3')
@Grab(group='org.apache.httpcomponents', module='httpclient', version='4.5')

// for some reason, this isn't able to resolve in my GroovyConsole -- I had to download into my .groovy/lib
//@GrabResolver(name='membrane', root='http://repository.membrane-soa.org/content/repositories/releases')
//@Grab(group='com.predic8', module='soa-model-core', version='1.5.3')

// for some reason, I'm getting "java.lang.NoClassDefFoundError: Unable to load class com.predic8.schema.SchemaComponent due to missing dependency Lorg/slf4j/Logger;" in my GroovyConsole when I don't have this
@GrabConfig(systemClassLoader=true, initContextClassLoader=true)

import com.predic8.wsdl.Definitions
import com.predic8.wsdl.Operation
import com.predic8.wsdl.PortType
import com.predic8.wsdl.WSDLParser

import com.predic8.schema.Declaration
import javax.xml.namespace.QName as JQName
import groovy.xml.QName

// the fix
MetaMethod originalSetType = Declaration.metaClass.getMetaMethod("setType", [Object])
Declaration.metaClass.setType = { Object obj ->
   if (obj)
       originalSetType.invoke((QName) obj)
}

// an example usage, demonstrating fix works
Definitions defs = new WSDLParser().parse("http://www.w3schools.com/webservices/tempconvert.asmx?WSDL")
for (PortType pt : defs.portTypes) {
    println pt.name
    for (Operation op : pt.operations)
      println "  -${op.name}"
}

由于您使用的是类（我假设在已编译的项目中），您可能会将修复程序放在静态块中。

Answer 3

升级到 1.6.0。例如。对于 Gradle 构建脚本：

compile "com.predic8:soa-model-core:1.6.0"
