若依前后端分离学习笔试
1.路由问题
注意这个是前端找到你的路由的路径。
2.表格开关按钮快速实现
html
<el-table-column label="状态" align="center" key="status">
<template slot-scope="scope">
<el-switch
v-model="scope.row.status"
active-value="0"
inactive-value="1"
@change="handleStatusChange(scope.row)"
></el-switch>
</template>
</el-table-column>
//methods add this method
// 状态修改
handleStatusChange(row) {
let text = row.status === "0" ? "启用" : "停用";
this.$modal.confirm('确认要"' + text + '""' + row.title + '"量表吗？').then(function() {
return changeStatus(row.scaleId,row.status);
}).then(() => {
this.$modal.msgSuccess(text + "成功");
}).catch(function() {
row.status = row.status === "0" ? "1" : "0";
});
},
// import this
import { listScaleInfo, getScaleInfo, delScaleInfo, addScaleInfo, updateScaleInfo, changeStatus } from "@/api/businessManagement/scaleBaseinfo";
// 修改分类状态
export function changeStatus(scaleId,status) {
const data = {
scaleId,
status
}
return request({
url: '/businessManage/scaleInfo/changeStatus',
method: 'put',
data: data
})
}
@Log(title = "修改状态", businessType = BusinessType.UPDATE)
@PutMapping("/changeStatus")
public AjaxResult changeStatus(@RequestBody ScaleBaseinfo scaleBaseinfo)
{
return toAjax(scaleBaseinfoService.changeStatus(scaleBaseinfo));
}
//interface generate this method automatically
@Override
public int changeStatus(ScaleBaseinfo scaleBaseinfo) {
return scaleBaseinfoMapper.updateScaleBaseinfo(scaleBaseinfo);
}3.选中指定的导出和批量导出
