java - Wildfly-9.0.2.Final 中的 ClassNotFoundException : javax. xml.datatype.DatatypeFactory

Question

Enviornment - AS@wildfly-9.0.2.Final, 
BuildingTool@ant,
JDK@jdk1.8.0_66

从我的 java 代码访问以下类，这导致了错误。

javax.xml.datatype.DatatypeFactory

Java claas 已配置为模块

jaroneapi'==>模块添加 --name=jaroneapi --resources=~/modules/jaroneapi.jar

package api.jarone.com.pojo;

import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.GregorianCalendar;
import javax.xml.datatype.XMLGregorianCalendar;
import javax.xml.datatype.DatatypeFactory;
public class TestJarOneDetails {
 public XMLGregorianCalendar convertDatetoXMLGregorian(String inputDate)
  {
    XMLGregorianCalendar date2 = null;
    try {
          System.out.println("[TestJarOne][convertDatetoXMLGregorian] This class is present in " +
                "jaroneapi.jar which has been configured as a module 'module add --name=jaroneapi --resources=~/modules/jaroneapi.jar' ");
          SimpleDateFormat fmt = new SimpleDateFormat("dd MMM yyyy HH:mm:ss");
          Date date = fmt.parse(inputDate);
          GregorianCalendar c = new GregorianCalendar();
          c.setTime(date);
          date2 = DatatypeFactory.newInstance().newXMLGregorianCalendar(c);
        } catch (Exception e) {
        e.printStackTrace();
    }
    return date2;
 }  
   }

访问上述“TestJarOneDetails”类时发生以下错误。

我认为我必须使用一些依赖项配置模块“jaroneapi”，但是/jdk1.8.0_66/jre/lib/rt.jar 中存在“javax.xml.datatype.DatatypeFactory”依赖项。

Answer 1

您需要在模块中添加对 javax.api 模块的依赖项。对于该命令，您只需添加 --dependencies=javax.api

module add --name=jaroneapi --resources=~/modules/jaroneapi.jar --dependencies=javax.api

或者您可以直接编辑 module.xml 并手动添加依赖项。

<module xmlns="urn:jboss:module:1.3" name="jaroneapi">

    <resources>
        <resource-root path="jaroneapi.jar"/>
    </resources>

    <dependencies>
        <module name="javax.api"/>
    </dependencies>
</module>
