jaxb绑定中的java.util.date问题


在spring mvc3中JACKSON序列化日期格式的问题（http://jackyrong.iteye.com/admin/blogs/1089909）一文中，提到了相关的日期问题。同样地，如果在JAXB中，REST形式返回的话，也有这样的问题，继续看例子： 
1）POJO类： 
   package com.loiane.model; 
import java.util.Date; 
public class Company { 
    private int id; 
    private String company; 
    private double price; 
    private double change; 
    private double pctChange; 
    private Date lastChange; 
    //getters and setters 
2）现在要返回company的集合，而且要用JAXB包装 
   import java.util.List; 
import javax.xml.bind.annotation.XmlElement; 
import javax.xml.bind.annotation.XmlRootElement; 
@XmlRootElement(name="companies") 
public class Companies { 
    @XmlElement(required = true) 
    private List<Company> list; 
    public void setList(List<Company> list) { 
        this.list = list; 
    } 
} 
而在SPRING CONTROLLER中，要返回如下的： 
  @RequestMapping(value="/company/view.action") 
public @ResponseBody Companies view() throws Exception {} 
这时，返回的XML为如下： 
<companies> 
    <list> 
        <change>0.02</change> 
        <company>3m Co</company> 
        <id>1</id> 
        <lastChange>2011-09-01T00:00:00-03:00</lastChange> 
        <pctChange>0.03</pctChange> 
        <price>71.72</price> 
    </list> 
    <list> 
        <change>0.42</change> 
        <company>Alcoa Inc</company> 
        <id>2</id> 
        <lastChange>2011-09-01T00:00:00-03:00</lastChange> 
        <pctChange>1.47</pctChange> 
        <price>29.01</price> 
    </list> 
</companies> 
可以看到，时间格式不是很好使，于是我们自定义进行格式化一下： 
package com.loiane.util; 
import java.text.SimpleDateFormat; 
import java.util.Date; 
import javax.xml.bind.annotation.adapters.XmlAdapter; 
public class JaxbDateSerializer extends XmlAdapter<String, Date>{ 
    private SimpleDateFormat dateFormat = new SimpleDateFormat("MM-dd-yyyy"); 
    @Override 
    public String marshal(Date date) throws Exception { 
        return dateFormat.format(date); 
    } 
    @Override 
    public Date unmarshal(String date) throws Exception { 
        return dateFormat.parse(date); 
    } 
} 
这里继承了XmlAdapter，并且进行了marshal和unmarshal，就是字符串日期和日期转字符，使用时，注意加上 @XmlJavaTypeAdapter 标签，如下 
import java.util.Date; 
import javax.xml.bind.annotation.adapters.XmlJavaTypeAdapter; 
import com.loiane.util.JaxbDateSerializer; 
public class Company { 
    private int id; 
    private String company; 
    private double price; 
    private double change; 
    private double pctChange; 
    private Date lastChange; 
    @XmlJavaTypeAdapter(JaxbDateSerializer.class) 
    public Date getLastChange() { 
        return lastChange; 
    } 
    //getters and setters 
} 
结果就正确输出了； 
<companies> 
    <list> 
        <change>0.02</change> 
        <company>3m Co</company> 
        <id>1</id> 
        <lastChange>09-01-2011</lastChange> 
        <pctChange>0.03</pctChange> 
        <price>71.72</price> 
    </list> 
    <list> 
        <change>0.42</change> 
        <company>Alcoa Inc</company> 
        <id>2</id> 
        <lastChange>09-01-2011</lastChange> 
        <pctChange>1.47</pctChange> 
        <price>29.01</price> 
    </list> 
</companies>
