jodatime持久化hibernate jpa
http://www.joda.org/joda-time-hibernate/index.html
JODA-TIME提供了一个功能更全面强大的功能组来替换JDK中的Date；
//字符串转日期
String timeString = "2006-01-26T13:30:00-06:00";
DateTime dateTime = new DateTime(timeString);
System.out.println(dateTime.toDate());
timeString = "2006-01-26";
dateTime = new DateTime(timeString);
System.out.println(dateTime);
java.sql.Timestamp setSendDate = Timestamp.valueOf("2006-01-26 13:30:00");
System.out.println(setSendDate);
//日期转字符串
org.joda.time.DateTime dateTime0 = new org.joda.time.DateTime ();
System.out.println(dateTime0);
System.out.println(dateTime0.toString("yyyy-MM-dd") + dateTime0.toString("hh:mm:ss") );
但是很多时候需要持久化日期到数据库中，比较流行的持久化框架Hibernate却并不支持JodaTime数据类型，hibernate支持的日期类型java.util.Date ,java.sql.Timestamp;
为了使jodaTime日期类型能够集成到hibernate框架中，需要加入jodaTime-hibernate ；
jodaTime-hibernate 1.3兼容 Hibernate 3.6 不支持 Hibernate 4.0；
如何获得jodaTime-hibernate？
<!-- Joda Time Library -->
<dependency>
<groupId>joda-time</groupId>

如何配置jodaTime-hibernate？
Hibernate mapping
Add the type attribute to your property configuration.
e.g.:
<property type="org.joda.time.contrib.hibernate.PersistentDateTime" name="dateTime"/>
Hibernate annotations
Set the type using the @org.hibernate.annotations.Type annotation.
e.g.:
@Column
@Type(type="org.joda.time.contrib.hibernate.PersistentDateTime")
private DateTime fromDate;
Sometimes there are multiple columns to be specified, as with PersistentDateTimeTZ:
@Columns(columns={@Column(name="startTime"),@Column(name="startTimezone")})
@Type(type="org.joda.time.contrib.hibernate.PersistentDateTimeTZ")
private DateTime startDateTime;
