JeecgBoot系列 测试接口异常Parameter ‘lists’ not found. Available parameters are [names, param1]

一、错误提示

根据提示可以简单看出是Parameter “lists” not found，而在我这个接口开发中，传到Mapper层的是一个list列表，而Mapper中已经使用了@Params(“names”)设置键。

  "success": false,
  "message": "操作失败，nested exception is org.apache.ibatis.binding.BindingException: Parameter 'lists' not found. Available parameters are [names, param1]",
  "code": 500,
  "result": null,
  "timestamp": 1668177771433

二、排查解决

根据排查因为我已经在入参的时候通过@param绑定了，所以这里的collection也就不能写"lists"，因为collection的值需要与@param绑定的参数名一致。

AccountController.java

@AutoLog(value = "测试-批量删除")
@ApiOperation(value="测试-批量删除", notes="测试-批量删除")
@DeleteMapping(value = "/deleteBatch")
public Result<?> deleteBatch(@RequestParam(name="names",required=true) String names) 
accountService.removeByNames(Arrays.asList(names.split(",")));
return Result.OK("批量删除成功!");

AccountMapper.java

removeByNames(@Param("names") List<String> names)

AccountMapper.xml

    <!--批量删除-->
    <delete id="removeByNames" parameterType="List">
        delete from account where name in
        <foreach collection="lists" item="names" open="(" separator="," close=")">
            #names
        </foreach>
    </delete>

因为在mapper里已经绑定了"names"，所以将AccountMapper.xml中批量删除语句中的collection值做修改

    <!--批量删除-->
    <delete id="removeByNames" parameterType="List">
        delete from account where name in
        <foreach collection="names" item="names" open="(" separator="," close=")">
            #names
        </foreach>
    </delete>

再次测试已经成功
