java - 无法实例化 RegionFactory [org.hibernate.cache.ehcache.EhCacheRegionFactory]

Question

我的域类如下。主键 ID 是 2 个字段 serviceProviderId 和 sportsId 的组合(分别存在于另一个表 serviceProvider 和 Sports 中)。当我启动我的 grails 应用程序时，出现以下异常

org.hibernate.MappingException:实体映射中的重复列:com.zonalde.FieldsDetails 列:service_provider_id(应使用 insert="false"update="false"进行映射)

我可能在这里遗漏了什么。我已经有了表并使用 Database Reverse Engineering Plugin 生成了域类

请帮忙

class FieldsDetails implements Serializable {

    Integer serviceProviderId
    Integer sportsId
    String isPaynPlay
    Boolean isActive
    Sports sports
    ServiceProvider serviceProvider

    int hashCode() {
        def builder = new HashCodeBuilder()
        builder.append serviceProviderId
        builder.append sportsId
        builder.toHashCode()
    }

    boolean equals(other) {
        if (other == null) return false
        def builder = new EqualsBuilder()
        builder.append serviceProviderId, other.serviceProviderId
        builder.append sportsId, other.sportsId
        builder.isEquals()
    }

    static belongsTo = [ServiceProvider, Sports]

    static mapping = {
        id composite: ["serviceProviderId", "sportsId"]
        version false

    }

    static constraints = {

        isPaynPlay nullable: true, maxSize: 1
        isActive nullable: true

    }
}

您需要将映射更新为:

static mapping = {
        id composite: ["serviceProviderId", "sportsId"]
        version false
        serviceProvider column: '`service_provider_id`', insertable: false, updateable: false
        sports column: '`sports_id`', insertable: false, updateable: false
    }
