【问题描述】：

我有一个基于 Apache CXF 的现有工作 java 解决方案来使用一些 SOAP 服务。 java 可执行文件和 shaded jar 在本地都可以正常工作。但是，当我尝试在 docker 中部署相同的解决方案时，代码

线程“main”中的异常 javax.xml.ws.WebServiceException: org.apache.cxf.service.factory.ServiceConstructionException: 失败创建服务。在 org.apache.cxf.jaxws.ServiceImpl.initialize(ServiceImpl.java:162) 在 org.apache.cxf.jaxws.ServiceImpl.(ServiceImpl.java:128) 在 org.apache.cxf.jaxws.spi.ProviderImpl.createServiceDelegate(ProviderImpl.java:82) 在 javax.xml.ws.Service.(Service.java:77) 在 com.flightview.BatchService.(BatchService.java:48) 在 de.lh.hixca.oag.ingestionraw.OAGIngestionMainClass.main(OAGIngestionMainClass.java:57) 造成的： org.apache.cxf.service.factory.ServiceConstructionException: 失败创建服务。在 org.apache.cxf.wsdl11.WSDLServiceFactory.(WSDLServiceFactory.java:87) 在 org.apache.cxf.jaxws.ServiceImpl.initializePorts(ServiceImpl.java:217) 在 org.apache.cxf.jaxws.ServiceImpl.initialize(ServiceImpl.java:160) ... 5 更多原因：javax.wsdl.WSDLException: WSDLException: faultCode=PARSER_ERROR: 解析问题 '文件：/usr/src/app/src/main/resources/jks/oag_wsdl.wsdl'.: java.io.FileNotFoundException: /usr/src/app/src/main/resources/jks/oag_wsdl.wsdl（没有这样的文件或目录）在 com.ibm.wsdl.xml.WSDLReaderImpl.getDocument(WSDLReaderImpl.java:2198) 在 com.ibm.wsdl.xml.WSDLReaderImpl.readWSDL(WSDLReaderImpl.java:2390) 在 com.ibm.wsdl.xml.WSDLReaderImpl.readWSDL(WSDLReaderImpl.java:2422) 在 org.apache.cxf.wsdl11.WSDLManagerImpl.loadDefinition(WSDLManagerImpl.java:266) 在 org.apache.cxf.wsdl11.WSDLManagerImpl.getDefinition(WSDLManagerImpl.java:165) 在 org.apache.cxf.wsdl11.WSDLServiceFactory.(WSDLServiceFactory.java:85) ... 7 更多原因：java.io.FileNotFoundException：/usr/src/app/src/main/resources/jks/oag_wsdl.wsdl（没有这样的文件或目录）在 java.io.FileInputStream.open0（本机方法）在 java.io.FileInputStream.open(FileInputStream.java:195) 在 java.io.FileInputStream.(FileInputStream.java:138) 在 java.io.FileInputStream.(FileInputStream.java:93) 在 sun.net.www.protocol.file.FileURLConnection.connect(FileURLConnection.java:90) 在 sun.net.www.protocol.file.FileURLConnection.getInputStream(FileURLConnection.java:188) 在 com.sun.org.apache.xerces.internal.impl.XMLEntityManager.setupCurrentEntity(XMLEntityManager.java:623) 在 com.sun.org.apache.xerces.internal.impl.XMLVersionDetector.determineDocVersion(XMLVersionDetector.java:148) 在 com.sun.org.apache.xerces.internal.parsers.XML11Configuration.parse(XML11Configuration.java:806) 在 com.sun.org.apache.xerces.internal.parsers.XML11Configuration.parse(XML11Configuration.java:771) 在 com.sun.org.apache.xerces.internal.parsers.XMLParser.parse(XMLParser.java:141) 在 com.sun.org.apache.xerces.internal.parsers.DOMParser.parse(DOMParser.java:243) 在 com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderImpl.parse(DocumentBuilderImpl.java:339) 在 com.ibm.wsdl.xml.WSDLReaderImpl.getDocument(WSDLReaderImpl.java:2188) ... 12 更多

我的示例 pom.xml 看起来像这样

我用于 docker build 的 dockerfile 是：

#
# Build stage
#
FROM maven:3.5-jdk-8 AS build
#copying .m2 settings.xml for profile
COPY settings.xml /root/.m2/
COPY src /usr/src/app/src
COPY pom.xml /usr/src/app
ENV http_proxy "http://<username>:<password>@<host>:<port>"
ENV https_proxy "http://<username>:<password>@<host>:<port>"
RUN apt-get update \
    && apt-get install --no-install-recommends -y openjfx \
    && apt-get clean
RUN mvn -f /usr/src/app/pom.xml clean package
#
# Package stage
FROM gcr.io/distroless/java
COPY --from=build /usr/src/app/target/ingestion-oag-using-soap-1.0-SNAPSHOT.jar /usr/app/ingestion-oag-using-soap-1.0-SNAPSHOT.jar
EXPOSE 8080
ENTRYPOINT ["java","-jar","/usr/app/ingestion-oag-using-soap-1.0-SNAPSHOT.jar"]

我的 wsdl2java 目标的 pom.xml 是否存在无法识别存储在资源文件夹中的完整 oag_wsdl.wsdl 路径的问题？如果是这样，我该如何调整我的 dockerfile？

标签： java docker maven dockerfile cxf

【解决方案1】：

看起来您的服务类是使用绝对路径（不是从类路径）生成的：

Caused by: java.io.FileNotFoundException: /usr/src/app/src/main/resources/jks/oag_wsdl.wsdl

尝试添加 wsdlLocation 参数以生成正确的 wsdl 路径：

<wsdlOptions>
    <wsdlOption>
        <wsdl>${basedir}/src/main/resources/jks/oag_wsdl.wsdl</wsdl>
        <wsdlLocation>classpath:jks/oag_wsdl.wsdl</wsdlLocation>
        <!-- <wsdlLocation>/jks/oag_wsdl.wsdl</wsdlLocation>  -->
    </wsdlOption>
</wsdlOptions>
