如果我使用 MySQL,我的实体和枚举会成功创建。
我将我的数据库更改为 PostgreSQL-9.4 。所以,我有一些错误如下:
...引起:org.hibernate.tool.schema.spi.SchemaManagementException:无法对 JDBC 目标执行模式管理 [创建表角色(id int8 不为空,名称枚举('ADMIN','USER','SEARCH' ) 不为空,主键 (id))] 在 org.hibernate.tool.schema.internal.TargetDatabaseImpl.accept(TargetDatabaseImpl.java:59) ~[hibernate-core-5.0.12.Final.jar:5.0.12.Final] 在 org.hibernate.tool.schema。 internal.SchemaMigratorImpl.applySqlString(SchemaMigratorImpl.java:431) ~[hibernate-core-5.0.12.Final.jar:5.0.12.Final] at org.hibernate.tool.schema.internal.SchemaMigratorImpl.applySqlStrings(SchemaMigratorImpl.java :420) ~[hibernate-core-5.0.12.Final.jar:5.0.12.Final] at org.hibernate.tool.schema.internal.SchemaMigratorImpl.createTable(SchemaMigratorImpl.java:236) ~[hibernate-core- 5.0.12.Final.jar:5.0.12.Final] 在 org.hibernate.tool.schema.internal.SchemaMigratorImpl.doMigrationToTargets(SchemaMigratorImpl.java:167) ~[hibernate-core-5.0.12.Final.jar:5.0 .12.Final] 在 org.hibernate.tool.schema.internal.SchemaMigratorImpl.doMigration(SchemaMigratorImpl.java:60) ~[hibernate-core-5.0.12.Final.jar:5.0.12.Final] 在 org.hibernate.tool.hbm2ddl.SchemaUpdate.execute(SchemaUpdate.java:134) ~[hibernate-core-5.0.12 .Final.jar:5.0.12.Final] 在 org.hibernate.tool.hbm2ddl.SchemaUpdate.execute(SchemaUpdate.java:101) ~[hibernate-core-5.0.12.Final.jar:5.0.12.Final]在 org.hibernate.internal.SessionFactoryImpl.(SessionFactoryImpl.java:472) ~[hibernate-core-5.0.12.Final.jar:5.0.12.Final] 在 org.hibernate.boot.internal.SessionFactoryBuilderImpl.build(SessionFactoryBuilderImpl .java:444) ~[hibernate-core-5.0.12.Final.jar:5.0.12.Final] at org.hibernate.jpa.boot.internal.EntityManagerFactoryBuilderImpl.build(EntityManagerFactoryBuilderImpl.java:879) ~[hibernate- entitymanager-5.0.12.Final.jar:5.0.12.Final] ...省略了22个常用框架执行(SchemaUpdate.java:134)~[hibernate-core-5.0.12.Final.jar:5.0.12.Final] at org.hibernate.tool.hbm2ddl.SchemaUpdate.execute(SchemaUpdate.java:101)~[hibernate -core-5.0.12.Final.jar:5.0.12.Final] 在 org.hibernate.internal.SessionFactoryImpl.(SessionFactoryImpl.java:472) ~[hibernate-core-5.0.12.Final.jar:5.0.12 .Final] 在 org.hibernate.boot.internal.SessionFactoryBuilderImpl.build(SessionFactoryBuilderImpl.java:444) ~[hibernate-core-5.0.12.Final.jar:5.0.12.Final] 在 org.hibernate.jpa.boot .internal.EntityManagerFactoryBuilderImpl.build(EntityManagerFactoryBuilderImpl.java:879) ~[hibernate-entitymanager-5.0.12.Final.jar:5.0.12.Final] ...省略22个常用框架执行(SchemaUpdate.java:134)~[hibernate-core-5.0.12.Final.jar:5.0.12.Final] at org.hibernate.tool.hbm2ddl.SchemaUpdate.execute(SchemaUpdate.java:101)~[hibernate -core-5.0.12.Final.jar:5.0.12.Final] 在 org.hibernate.internal.SessionFactoryImpl.(SessionFactoryImpl.java:472) ~[hibernate-core-5.0.12.Final.jar:5.0.12 .Final] 在 org.hibernate.boot.internal.SessionFactoryBuilderImpl.build(SessionFactoryBuilderImpl.java:444) ~[hibernate-core-5.0.12.Final.jar:5.0.12.Final] 在 org.hibernate.jpa.boot .internal.EntityManagerFactoryBuilderImpl.build(EntityManagerFactoryBuilderImpl.java:879) ~[hibernate-entitymanager-5.0.12.Final.jar:5.0.12.Final] ...省略22个常用框架Final.jar:5.0.12.Final] 在 org.hibernate.internal.SessionFactoryImpl.(SessionFactoryImpl.java:472) ~[hibernate-core-5.0.12.Final.jar:5.0.12.Final] 在 org.hibernate .boot.internal.SessionFactoryBuilderImpl.build(SessionFactoryBuilderImpl.java:444) ~[hibernate-core-5.0.12.Final.jar:5.0.12.Final] at org.hibernate.jpa.boot.internal.EntityManagerFactoryBuilderImpl.build( EntityManagerFactoryBuilderImpl.java:879) ~[hibernate-entitymanager-5.0.12.Final.jar:5.0.12.Final] ...省略22个常用框架Final.jar:5.0.12.Final] 在 org.hibernate.internal.SessionFactoryImpl.(SessionFactoryImpl.java:472) ~[hibernate-core-5.0.12.Final.jar:5.0.12.Final] 在 org.hibernate .boot.internal.SessionFactoryBuilderImpl.build(SessionFactoryBuilderImpl.java:444) ~[hibernate-core-5.0.12.Final.jar:5.0.12.Final] at org.hibernate.jpa.boot.internal.EntityManagerFactoryBuilderImpl.build( EntityManagerFactoryBuilderImpl.java:879) ~[hibernate-entitymanager-5.0.12.Final.jar:5.0.12.Final] ...省略22个常用框架EntityManagerFactoryBuilderImpl.build(EntityManagerFactoryBuilderImpl.java:879) ~[hibernate-entitymanager-5.0.12.Final.jar:5.0.12.Final] ...省略22个常用框架EntityManagerFactoryBuilderImpl.build(EntityManagerFactoryBuilderImpl.java:879) ~[hibernate-entitymanager-5.0.12.Final.jar:5.0.12.Final] ...省略22个常用框架

我的枚举:
public enum RoleType {
ADMIN("ADMIN"),
SEARCH("SEARCH"),
USER("USER");
private final String value;
RoleType(final String value) {
this.value = value;
}
@Override
public String toString() {
return value;
}
}
我的角色类:
@Entity
@Table(name = "role")
public class Role {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@JsonIgnore
private Long id;
@NotNull
@Enumerated(EnumType.STRING)
@Column(columnDefinition = "enum('ADMIN', 'USER', 'SEARCH')")
private RoleType name;
@ManyToMany(mappedBy = "roles")
@JsonIgnore
private Set<User> users;
public Role() {
}
public Role(RoleType name) {
this.name = name;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public RoleType getName() {
return name;
}
public void setName(RoleType name) {
this.name = name;
}
public Set<User> getUsers() {
return users;
}
public void setUsers(Set<User> users) {
this.users = users;
}
@Override
public String toString() {
return name.toString();
}
}
我的 postgresql 的 application.yml 文件:
spring:
datasource:
url: jdbc:postgresql://localhost:5432/mydb?autoReconnect=true&useSSL=false
username: username
password: password
driverClassName: org.postgresql.Driver
jpa:
hibernate:
ddl-auto: update
properties:

我用于 mysql 的旧 application.yml 文件:
spring:
datasource:
url: jdbc:mysql://localhost:3306/mydb?autoReconnect=true&useSSL=false
username: user
password: password
driverClassName: com.mysql.jdbc.Driver

如何将其配置为自动生成枚举类型?
