### 一、vue导出excel文件打不开，或者文件内容为object object ###

报错：

打开文件后：

**原因：后端排查过后，发现生成的数据没有问题，于是把res打印出来发现返回的是 object object，并不是 object blob  
查看了response响应拦截里，如果类型是bolb，返回的是response，所以是返回值出错了，我们要的是res.data,而不是res**

// 响应拦截
    service.interceptors.response.use(
      (response) => {
        
        window.gvm.$Loading.hide()
        const res = response.data
        if (response.config.responseType === "blob") {
        
          return response
        }
        if (res.appcode !== "0") {
        
          const error = response.msg || res.msg || "Error"
          toastError(error)
          console.log("error", error)
          return false
          // return Promise.reject(new Error(error))
        } else {
        
          return res
        }
      },
      (error) => {
        
        // window.gvm.$Loading.hide()
        if (error.message === "Request failed with status code 401") {
        
          let errmsg = "登录过期"
          const hasToken = !isEmpty(getToken())
          console.log(hasToken)
          if (hasToken) {
        
            errmsg = "登录过期,请重新登录"
          } else {
        
            errmsg = "请先登录"
          }
          window.gvm.$message.error(errmsg)
        }
        return Promise.reject(error)
      }
    )

### 二、java后端生成Excel时可以正常生成文件流下载文件，但报错：org.springframework.web.HttpMediaTypeNotAcceptableException: Could not find acceptable representatio ###

Spring boot 项目中进行下载文件的时候出现的异常，当前异常出现之后，文件还是能够下载：

**原因：返回值不是void，返回值修改成 viod 就可以解决这一个问题**

### 三、Excel下载内容出现问题 ###

**原因：poi和poi-poom的坐标不一致导致的，统一版本即可。**
