我正在尝试更新当前登录用户的密码。但这向我显示了空点异常。
配置文件控制器:
def doPasswordChange(){
def response = authenticationService.getMember()
if (!response) {
flash.message = AppUtil.infoMessage(g.message(code: "invalid.entity"), false)
redirect(controller: "profile", action: "changePassword")
} else {
response = profileService.doPasswordChange(response, params)
if (!response.isSuccess) {
flash.redirectParams = response.model
flash.message = AppUtil.infoMessage(g.message(code: "password.not.change"), false)
redirect(controller: "profile", action: "changePassword")
} else {
flash.message = AppUtil.infoMessage(g.message(code: "updated"))
redirect(controller: "profile", action: "index")
}
}
}
ProfileService:
def doPasswordChange(Member member, GrailsParameterMap params){
params.password = params.password.encodeAsMD5()
params.newPassword = params.newPassword.encodeAsMD5()
params.confirmPassword = params.confirmPassword.encodeAsMD5()
def response = AppUtil.saveResponse(false, member)
if(member.password==params.password && params.confirmPassword==params.newPassword){
member.password = params.newPassword //this line is gives me null point exception
if(member.validate()){
log.warn myDomainObj.errors.allErrors.join(' \n')
member.save(flush: true, failOnError:true)
response.isSuccess = true
}
else println("ok")
}
return response
}
给我这个错误:

我只尝试给其他成员类属性分配一个新值。同样的错误。 我该怎么解决?
答案 0 :(得分:0)
以表格
添加属性useToken =“ true”<g:form name="applyForm" useToken="true">
//ur code
</g:form>
在控制器中
将您的操作代码放入withForm {}
withForm {
//ur origin code in action
}.invalidToken {
//what to do when token invalidate
}
