static mapping = {
password column: '`password`'
tablePerHierarchy false

Set<AuthRole> getAuthorities() {
AuthUserAuthRole.findAllByAuthUser(this).collect { it.authRole }
}

encodePassword()
}
def beforeUpdate() {

encodePassword()
}
}

}
String toString() {

您可以使用grails导出插件将数据导出到excel、csv、pdf等。它易于配置和使用
以下是链接:我在工作中使用了该插件,但在2.4.4上,它根本就坏了,我正在考虑使用java POI for excel或itext for pdf/word,如果我在grails导出中成功,我会通知您。
def list = {
if(!params.max) params.max = 10
if(params?.exportFormat && params.exportFormat != "html"){ //must change to exportFormat cause format is reserved for the default grails format
response.contentType = grailsApplication.config.grails.mime.types[params.exportFormat]
response.setHeader("Content-disposition", "attachment; filename=AuthUser.${params.extension}")
exportService.export(params.exportFormat, response.outputStream,AuthUser.list(params), [:], [:])
}
// [ authUserInstanceList: AuthUser.list( params ) ] you have to comment this or give an else clause since the response already called before
