Grails/Groovy-在映射中返回MySQL记录只保留最后一条记录

我试图遍历表数据并将表记录保存到Groovy映射中，但映射中只保存最后一条记录

服务代码

class EmployeeService {

    def dataSource

    def printTable(){
        def sql = new Sql(dataSource)
        def tableMap = [:]
        int count=0
        sql.eachRow("SELECT * FROM employee") { row ->
            tableMap.'first_name' = row.first_name
            tableMap.'last_name' = row.last_name
            tableMap.'born' = row.born
            print "\nIteration No " + count
            count++
        }
        sql.close()
        for ( e in tableMap ) {print "key = ${e.key}, value = ${e.value}"}
    }

下表员工记录：

这是完成迭代后地图的内容：

试试这个

    def list = []
    int count = 0
    sql.eachRow("SELECT * FROM employee") { row ->
        def tableMap = [:]
        tableMap.'first_name' = row.first_name
        tableMap.'last_name' = row.last_name
        tableMap.'born' = row.born
        list << tableMap
        print "\nIteration No " + count
        count++
    }
    list.each {
    for (def e in it) {
        print "key = ${e.key}, value = ${e.value}"
    }
}

def list=[]
整数计数=0
sql.eachRow（“从员工中选择*）{row->
def tableMap=[：]
tableMap.“first\u name”=行。first\u name
tableMap.“last\u name”=行。last\u name
tableMap.born'=行.born
列表试试这个

        tableMap.'first_name' = row.first_name
        tableMap.'last_name' = row.last_name
        tableMap.'born' = row.born
        list << tableMap
        print "\nIteration No " + count
        count++
    }
    list.each {
    for (def e in it) {
        print "key = ${e.key}, value = ${e.value}"
    }
}

tableMap.born'=行.born
列出或只使用返回GroovyResultSet的sql.rows（）。不需要像这样循环每个结果。或者只使用返回GroovyResultSet的sql.rows（）。不需要像这样循环每个结果。
