关于vue+springboot批量删除遇到的问题，附上代码

js

// 批量删除
deleteBathById(){
debugger
let self=this
let ids= this.sels.map(item => item.id).join()//获取所有选中行的id组成的字符串，以逗号分隔
console.log(ids)
this.$confirm(‘此操作将永久删除该文件及其子文件, 是否继续?’, ‘提示’, {
confirmButtonText: ‘确定’,
cancelButtonText: ‘取消’,
type: ‘warning’
}).then(() => {
axios.post("/api/mmContractTemplate/deleteBathById",{ids:ids}).then(function(response){
self.loadingData();
alert(“删除成功”)
})
})
},

后端
controller

@IgnoreAuth
    @RequestMapping(value = "/deleteBathById")
    public BaseResponse deleteBathById(@RequestBody HashMap<String, String> parasmap ) {
        String ids = parasmap.get("ids");
        String[] id = ids.split(",");
        int result = mmContractTemplateManager.deleteBathById(id);
        if (result > 0) {
            return baseUtilService.setResultSuccess("删除成功");
        } else {
            return baseUtilService.setResultSuccess("删除失败");
        }
    }

service

/**
  * 根据id批量删除
  * @param
  * @return
  */
 int deleteBathById(String[] id);

impl

   @Override
    @Transactional
    public int deleteBathById(String[] id) {
        return this.baseMapper.deleteBathById(id);
    }

mapper

int deleteBathById( String[] id);

xml

 <!--批量删除-->
    <delete id="deleteBathById" parameterType="java.lang.String">
        delete from mm_contract_template where mould_id in
        <foreach collection="array" item="id"  open="(" separator="," close=")">
            #{id}
        </foreach>
    </delete>

遇到请求报错Required String parameter ‘id’ is not present问题，具体解决问题如下

之前用的是String接收

所以删除不了
如果前端传入的是json数据那么后端使用
@RequestBody HashMap<String, String> map
进行接收，然后再通过map.get(“id”)获取对应的数据

如果前端传入的是正常表单数据，那么后端使用
@RequestParam(“id”) String id或者
@RequestParam(value=“id”, required = false) String id接收参数

需要注意的是，如果请求类型为delete并且参数类型不是json的话，不能使用通过表单类型提交，参数需要跟到请求url后面，并且后台使用@PathVariable进行获取参数
