数据库字段gender为枚举类型，从前台接受到实体后进行保存报错：org.postgresql.util.PSQLException: ERROR: column "gender" is of type gender but expression is of type character varying
==========================
本篇文章从解决这个报错入手，附带
1.@TypeDef/@Enumerated/@Type的使用！！！！！
==========================
2.hibernate映射枚举类型的解决方案！！！！
==========================
报错如下：
2018-04-09 15:28:53.495 ERROR 64280 --- [nio-8080-exec-1] o.a.c.c.C.[.[.[/].[dispatcherServlet] : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.dao.InvalidDataAccessResourceUsageException: could not execute statement; SQL [n/a]; nested exception is org.hibernate.exception.SQLGrammarException: could not execute statement] with root cause org.postgresql.util.PSQLException: ERROR: column "gender" is of type gender but expression is of type character varying
建议：You will need to rewrite or cast the expression.

解析问题：
1.首先这个问题出错，是因为数据库中gender性别这个字段设置的是枚举类型gender
2.其次，这个和你使用什么数据库没有关系，而是应该注意hibernate的映射枚举类型的做法怎么解决
解决方法：
1.首先，需要你需要单独写一个枚举类，来作为gender这个字段的类型
package com.sxd.sweeping.entity;
public enum Gender {
Male("男",1),
Female("女",2),
Unknow("未知",3);
private String displayName;
private int index;
private Gender(String displayName,int index){
this.displayName = displayName;
this.index = index;
}
}
2.其次，你需要单独的对hibernate的枚举类型进行映射处理
package com.sxd.sweeping.entity; import org.hibernate.HibernateException;
import org.hibernate.engine.spi.SharedSessionContractImplementor;
import org.hibernate.type.EnumType; import java.sql.PreparedStatement;
import java.sql.SQLException;
import java.sql.Types; public class PostgreSQLEnumType extends EnumType { @Override
public void nullSafeSet(PreparedStatement st, Object value, int index, SharedSessionContractImplementor session) throws HibernateException, SQLException {
if(value == null){
st.setNull(index, Types.OTHER);
}else{
st.setObject(index,value.toString(),Types.OTHER);
}
}
}
3.最后，你需要在User实体类中对这个字段使用注解进行标注
package com.sxd.sweeping.entity; import com.fasterxml.jackson.annotation.JsonIgnore;
import lombok.Data;
import org.hibernate.annotations.Type;
import org.hibernate.annotations.TypeDef; import javax.persistence.*;
import java.sql.Date; @Data
@Entity
@Table(name = "users", schema = "auth")
@TypeDef(name="pgsql_enum",typeClass = PostgreSQLEnumType.class)
public class User { @Id
@Column(name = "id", nullable = false)
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
@Basic
@Column(name = "mobile", nullable = false)
private String mobile;
@Basic
@Column(name = "realname", nullable = false)
private String realname;
@Column(name = "gender", nullable = false, columnDefinition = "GENDER")
@Enumerated(EnumType.STRING)
@Type(type = "pgsql_enum")
private Gender gender = Gender.Unknow;
@Basic
@Column(name = "avatar", nullable = false)
private String avatar;
@Basic
@Column(name = "password", nullable = false)
@JsonIgnore
private String password;
@Basic
@Column(name = "last_ip", nullable = true)
private String lastIP;
@Basic
@Column(name = "last_login", nullable = true)
private Date lastLogin;
@Basic
@Column(name = "banned_at", nullable = true)
private Date bannedAt;
@Basic
@Column(name = "ban_reason", nullable = true)
private String banReason;
@Basic
@Column(name = "created_at", nullable = false)
private Date createAt;
@Basic
@Column(name = "created_by", nullable = true)
private Long createBy;
@Basic
@Column(name = "updated_at", nullable = false)
private Date updateAt;
@Basic
@Column(name = "updated_by", nullable = true)
private Long updateBy;
@Basic
@Column(name = "deleted_at")
private Date deletedAt;
@Basic
@Column(name = "deleted_by")
private Long deleteBy; }
4.这样就完成了这个问题的解决方案！！！！
