java - @Type(类型=“pg-uuid”)的注释未找到“pg-uuid”类异常

Question

我在尝试使用annotation@type（type=“pg uuid”）时遇到了一些问题。它抛出此异常：

Caused by: java.lang.ClassNotFoundException: Could not load requested class : pg-uuid

我的所有实体都在这个结构中：

package entv.enterprise.application.core.entity;

import java.io.Serializable;
import java.util.Date;
import java.util.UUID;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;
import javax.persistence.Temporal;
import javax.persistence.TemporalType;
import javax.validation.constraints.NotNull;
import javax.validation.constraints.Size;

import org.hibernate.annotations.Type;
import org.springframework.format.annotation.DateTimeFormat;

@Entity
@Table(name="user")
public class User implements Serializable {

private static final long serialVersionUID = 1L;

@Id
@Column(name="iduser")
@Type(type="pg-uuid")
@NotNull
private UUID id;

@NotNull
@Column(name="username", length=100)
private String username;

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

@Column(name="email", length=200)
private String email;

@NotNull
@Column(name="bolactive")
private Integer bolActive;

@NotNull
@Column(name="bolvalid")
private Integer bolValid;

@DateTimeFormat (pattern="dd/MM/yyyy")
@Column(name="dateRegistry")
@Temporal(TemporalType.TIMESTAMP)
@NotNull
private Date dateRegistry;

public UUID getId() {
    return id;
}

public void setId(UUID id) {
    this.id = id;
}

public String getUsername() {
    return username;
}

public void setUsername(String username) {
    this.username = username;
}

public String getPassword() {
    return password;
}

public void setPassword(String password) {
    this.password = password;
}

public String getEmail() {
    return email;

public void setEmail(String email) {
    this.email = email;
}

public Integer getBolActive() {
    return bolActive;
}

public void setBolActive(Integer bolActive) {
    this.bolActive = bolActive;
}

public Integer getBolValid() {
    return bolValid;
}

public void setBolValid(Integer bolValid) {
    this.bolValid = bolValid;
}

public Date getDateRegistry() {
    return dateRegistry;
}

public void setDateRegistry(Date dateRegistry) {
    this.dateRegistry = dateRegistry;
}

@Override
public int hashCode() {
    final int prime = 31;
    int result = 1;
    result = prime * result + ((id == null) ? 0 : id.hashCode());
    return result;
}

@Override
public boolean equals(Object obj) {
    if (this == obj)
        return true;
    if (obj == null)
        return false;
    if (getClass() != obj.getClass())
        return false;
    User other = (User) obj;
    if (id == null) {
        if (other.id != null)
            return false;
    } else if (!id.equals(other.id))
        return false;
    return true;
}
}

如果我在type=中使用“org.hibernate.type.postgresuuidtype”，它会抛出：
JDBC类型1111没有方言映射
2016年12月8日编辑：我不知道为什么，但在项目清理之后，问题似乎已经解决了。

Answer 1

改用这个annotation。

@org.hibernate.annotations.Type(type = "org.hibernate.type.PostgresUUIDType")
