JDK8不能与JDK8(WS客户端）一起工作

Question

我有一个非常简单的（现有的）web服务，我希望使用JDK8生成一个web服务客户机。

我使用的是纯JDK8工具链，这意味着我使用的是JDK8目录中的wsimport工具。

现在问题来了:JDK8中的wsimport工具生成的Java源代码不符合JDK8 Javadoc。正如您可能知道的那样，Javadoc工具在JDK8中变得更加严格。

请考虑以下简单模式：

<xs:schema version="1.0" targetNamespace="http://mavenwsserver.ws.mytest.org/">
  <xs:element name="operation" type="tns:operation"/>
  <xs:element name="operationResponse" type="tns:operationResponse"/>
  <xs:complexType name="operation">
    <xs:sequence>
      <xs:element name="person" type="tns:person" minOccurs="0"/>
    </xs:sequence>
  </xs:complexType>
  <xs:complexType name="person">
    <xs:sequence>
      <xs:element name="firstName" type="xs:string" minOccurs="0"/>
      <xs:element name="lastName" type="xs:string" minOccurs="0"/>
    </xs:sequence>
  </xs:complexType>
  <xs:complexType name="operationResponse">
    <xs:sequence>
      <xs:element name="return" type="xs:string" minOccurs="0"/>
    </xs:sequence>
  </xs:complexType>
</xs:schema>

为此，wsimport工具将生成Java代码，如下所示：

package org.mytest.ws.mavenwsclient;

import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlType;


/**
 * <p>Java class for person complex type.
 * 
 * <p>The following schema fragment specifies the expected content contained within this class.
 * 
 * <pre>
 * &lt;complexType name="person">
 *   &lt;complexContent>
 *     &lt;restriction base="{http://www.w3.org/2001/XMLSchema}anyType">
 *       &lt;sequence>
 *         &lt;element name="firstName" type="{http://www.w3.org/2001/XMLSchema}string" minOccurs="0"/>
 *         &lt;element name="lastName" type="{http://www.w3.org/2001/XMLSchema}string" minOccurs="0"/>
 *       &lt;/sequence>
 *     &lt;/restriction>
 *   &lt;/complexContent>
 * &lt;/complexType>
 * </pre>
 * 
 * 
 */
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "person", propOrder = {
    "firstName",
    "lastName"
})
public class Person {

    protected String firstName;
    protected String lastName;

    /**
     * Gets the value of the firstName property.
     * 
     * @return
     *     possible object is
     *     {@link String }
     *     
     */
    public String getFirstName() {
        return firstName;
    }

    /**
     * Sets the value of the firstName property.
     * 
     * @param value
     *     allowed object is
     *     {@link String }
     *     
     */
    public void setFirstName(String value) {
        this.firstName = value;
    }

    /**
     * Gets the value of the lastName property.
     * 
     * @return
     *     possible object is
     *     {@link String }
     *     
     */
    public String getLastName() {
        return lastName;
    }

    /**
     * Sets the value of the lastName property.
     * 
     * @param value
     *     allowed object is
     *     {@link String }
     *     
     */
    public void setLastName(String value) {
        this.lastName = value;
    }

}

链接到WSDL（包括模式）

将此文件下载到硬盘上的某个地方。

我使用的wsimport命令行如下所示：

mkdir D:\JavaDevHG\MavenWSClient\target\generated-sources\jaxws-wsimport

"C:\Program Files\Java\jdk1.8.0_05\bin\wsimport" -keep ^
  -s D:\JavaDevHG\MavenWSClient\target\generated-sources\jaxws-wsimport ^

   -sourcepath D:\JavaDevHG\MavenWSClient\target\generated-sources\jaxws-wsimport ^

Answer 1

我只能证实你的发现。由于重现此代码所需的设置很少，没有任何漏洞，因此到目前为止唯一合理的结论是，这是OpenJDK8附带的wsimport工具中的一个bug。这个工具只是没有更新来反映由同一JDK包的javadoc工具施加的新限制。
