我需要将当前日期和时间导入格式为TimeStamp的MySQL数据库字段中。从检查样本数据来看，MySQL
TimeStamp数据类型的格式似乎是“ yyyy-mm-dd hh：mm：ss”。我在springhibernate应用程序中使用Joda-
Time
格式。如何获得基础MySQL
TimeStamp格式化字段可以接受的格式的当前日期时间？

这是我当前的代码，由于eclipse表示.parseDateTime（）需要字符串参数而不是DateTime参数，因此无法编译：

public void setCreated(){
    DateTime now = new org.joda.time.DateTime();
    DateTimeFormatter fmt = DateTimeFormat.forPattern("yyyy-MM-dd hh:mm:ss");
    created = fmt.parseDateTime(now);
    System.out.println("'''''''''''''''''''''' created is: "+created);
}

我要保留的实体定义如下：

@Entity
@Table(name = "documents")
public class Document {
@Id
@GeneratedValue
@Column(name="id")
private Integer id;

@ManyToOne
@JoinColumn(name = "client_id")
private Patient patient;

@ManyToOne
@JoinColumn(name = "type_id")
private DocumentType type;

@Column(name="name")
private String name;

@Column(name="description")
private String description;

@Column(name="filename")
private String filename;

@Column(name="content")
@Lob
private Blob content;

@Column(name="content_type")
private String contentType;

@Column(name = "created")
private DateTime created;

public Integer getId(){return id;}
public void setId(Integer i){id=i;}

protected void setPatient(Patient patient) {this.patient = patient;}
public Patient getPatient(){return this.patient;}

public void setType(DocumentType type) {this.type = type;}
public DocumentType getType() {return this.type;}

public String getName(){return name;}
public void setName(String nm){name=nm;}

public String getDescription(){return description;}
public void setDescription(String desc){description=desc;}

public String getFileName(){return filename;}
public void setFileName(String fn){filename=fn;}

public Blob getContent(){return content;}
public void setContent(Blob ct){content=ct;}

public String getContentType(){return contentType;}
public void setContentType(String ctype){contentType=ctype;}

public void setCreated(){
    DateTime now = new org.joda.time.DateTime();
    DateTimeFormatter fmt = DateTimeFormat.forPattern("yyyy-MM-dd hh:mm:ss");
    created = fmt.parseDateTime(now);
System.out.println("''''''''''''''''''''''''''' created is: "+created);
}
public DateTime getCreated() {return this.created;}

@Override
public String toString() {return this.getName();}
public boolean isNew() {return (this.id == null);}

}

如何更改上述内容，以便它以正确的格式保存数据以插入到MySQL TimeStamp字段中？
