使用xjc将xml文件转换成javabean

 1.先将xml文件转换xsd文件

原xml文件：Response.xml

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Response>
<code>0</code>
<message>abcd</message>
</Response>

xsd文件：Response.xsd

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">
  <xs:element name="Response">
    <xs:complexType>
      <xs:sequence>
        <xs:element ref="code"/>
        <xs:element ref="message"/>
      </xs:sequence>
    </xs:complexType>
  </xs:element>
  <xs:element name="code" type="xs:string"/>
  <xs:element name="message" type="xs:string"/>
</xs:schema>

2.先指定一个目录存放该***.java    例：  D:\trang

cmd进入到该目录

xjc  Response.xsd   -p   Response.bean

生成的JavaBean如下：Response.java

package Response.bean;

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

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "", propOrder = {
    "code",
    "message"
})
@XmlRootElement(name = "Response")
public classResponse {

    @XmlElement(required = true)
    protected String code;
    @XmlElement(required = true)
    protected String message;

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

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

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

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

}

3.将所有的xsd文件转换成javabean

xjc *.xsd -p  com.xyz..bean      （com.xyz..bean）为包名。
