Question

我在尝试运行我的grails应用程序时不断收到此错误，任何人都可以告诉可能是什么问题。

以下是导致此错误的控制器方法，它通过视图中select的ajax调用获取其参数。

    def optionsBySelection()
        {
            log.error "hej11 ${params}"
            Sql sql = new Sql(dataSource)
            Map query = [params: params]
                def optSelection = sql.rows("select distinct :params from log_entry",query).each { row->
                    log.error "hej22 ${row}"
            }

                render (template: "selection" , model: [optSelection]) as JSON
}




ERROR errors.GrailsExceptionResolver  - NotSerializableException occurred when processing request: [POST] /admin/optionsBySelection - parameters:

您正在尝试将整个GrailsParameterMap实例放入准备好的SQL查询中。您不能这样做，而应该创建一个新映射，其中包含要传递给SQL查询的参数子集。

POST请求中的Grails NotSerializableException
