Question

我正在尝试按其客户名称订购我的位置类，但由于某些原因无效。这是查询出错的部分：

columns.each {
                String searchValue = it.options['searchValue']
                String domainName = it.options['domainName']
            columns.each {
                String orderValue = it.options['order']
                String domainName = it.options['domainName']
                if (orderValue) {
                    if (domainName == 'parentName') {
                        order('parent.name', orderValue)
                    } else if(domainName == 'customer'){
                        order('customer.name', orderValue)
                    } else if (domainName == 'type') {
                        order('type.name', orderValue)
                    } else if (domainName == 'devices') {
                        orderDevice = true
                        orderDeviceValue = orderValue
                    } else if (domainName =='tags'){
                        log.info("sort by tag")
                        orderTag = true
                        orderTagValue = orderValue
                    } else if (domainName == 'description') {
                        order('description', orderValue)
                    } else {
                        order(domainName, orderValue)
                    }
                }
            }

这是位置类：

import groovy.transform.ToString

@ToString
class Location implements Comparable<Location> {

    Company customer
    Location parent
    String name
    String description
    String objectnumber
    String address
    String zipcode
    String province
    String city
    String country
    Long longitude
    Long latitude
    Integer order
    String timezone
    AlertConfiguration alertConfiguration
    boolean deleted
    LocationType type

    static mapping = {
        order column: '`order`'
        name column: '`name`'
        version false
    }

    static constraints = {
        parent nullable: true
        description nullable: true, maxSize: 65535
        objectnumber nullable: true
        province nullable: true
        city nullable: true
        longitude nullable: true
        latitude nullable: true
        order nullable: true
        timezone nullable: true
        type nullable: true
        alertConfiguration nullable: true
        parent nullable: true
        address nullable: true
        zipcode nullable: true
        country nullable: true, maxSize: 3
    }

    @Override
    int compareTo(Location that) {
        if (that) {
            return this.name.compareTo(that.name)
        }
        return 0
    }

    @Override
    String toString() {
        return "location:"+id
    }
}

这是公司课程：

import groovy.transform.ToString

@ToString
class Company {

    String name
    String address
    String zipcode
    String province
    String city
    String country
    String phonenumber
    String email
    String website
    String cocnumber
    String vatnumber
    String logoUrl
    boolean deleted
    Account account
    String contractholder
    String initial_contract

    static mapping = {
        email column: 'emailaddress'
        version false
    }

    static hasMany =[locations: Location]

    static constraints = {
        address nullable: true
        zipcode nullable: true, maxSize: 45
        province nullable: true
        city nullable: true
        country nullable: true, maxSize: 3
        phonenumber nullable: true, maxSize: 45
        email nullable: true, email:true
        website nullable: true
        cocnumber nullable: true
        vatnumber nullable: true
        logoUrl nullable: true, url: true
        account nullable: true
        contractholder nullable: true
        initial_contract nullable: true
    }

    Company(String name) {
        System.out.println("Company constructor " + name)
    }
}

我确实有一个与公司类相关联的帐户类，并使用我可以在公司名称上订购，但由于某种原因，按客户名称排序位置会引发错误：

无法解析属性：customer.name of：com.x.Location。 Stacktrace如下：java.lang.reflect.InvocationTargetException：null 在 grails.plugin.springsecurity.web.filter.GrailsAnonymousAuthenticationFilter.doFilter（GrailsAnonymousAuthenticationFilter.groovy：53）在 grails.plugin.springsecurity.web.authentication.logout.MutableLogoutFilter.doFilter（MutableLogoutFilter.groovy：62）在 grails.plugin.springsecurity.web.SecurityRequestHolderFilter.doFilter（SecurityRequestHolderFilter.groovy：58）在 java.util.concurrent.ThreadPoolExecutor.runWorker（ThreadPoolExecutor.java:1142）在 java.util.concurrent.ThreadPoolExecutor中的$ Worker.run（ThreadPoolExecutor.java:617）在java.lang.Thread.run（Thread.java:745）引起： org.hibernate.QueryException：无法解析属性： customer.name of：com.x.Location at grails.orm.PagedResultList。（PagedResultList.java：43）at grails.orm.HibernateCriteriaBuilder.createPagedResultList（HibernateCriteriaBuilder.java:160）在。com.x.location.LocationService $ tt__findAllByAccount（LocationService.groovy：60）在 grails.transaction.GrailsTransactionTemplate $ 2.doInTransaction（GrailsTransactionTemplate.groovy：96）在 grails.transaction.GrailsTransactionTemplate.execute（GrailsTransactionTemplate.groovy：93）在。com.x.location.LocationBusinessService $ tt__list（LocationBusinessService.groovy：62）在 grails.transaction.GrailsTransactionTemplate $ 2.doInTransaction（GrailsTransactionTemplate.groovy：96）在 grails.transaction.GrailsTransactionTemplate.execute（GrailsTransactionTemplate.groovy：93）在 com.x.location.LocationRestController.list（LocationRestController.groovy：29） ...省略了6个常见帧
