Question

我有一个名为UserDTO的域对象

这是我的mapper.xml文件配置

<insert id="insertUser" useGeneratedKeys="true" keyProperty="id" parameterType="com.myapp.dto.UserDTO">
    insert into
    tblusers(username,password,email,phone,role,is_active,security_question,securtiy_answer,first_name,last_name)
    values(#{username},#{password},#{email},#{phone},#{role,typeHandler=com.greenflight.typehandlers.StringArrayListTypeHandler},#{is_active},#{security_question},#{securtiy_answer},#{first_name},#{last_name})
</insert>

但这就像这样抛出异常

  Caused by: org.apache.ibatis.exceptions.PersistenceException: 
### Error updating database.  Cause: org.apache.ibatis.executor.ExecutorException: Error getting generated key or setting result to parameter object. Cause: org.apache.ibatis.executor.result.ResultMapException: Error attempting to get column #1 from result set.  Cause: org.postgresql.util.PSQLException: Bad value for type long : asdfds
### The error may involve org.mybatis.myapp.Mapper.insertUser-Inline

    at com.greenflight.dao.UserDAO.CreateNewUser(UserDAO.java:98)

我查看了mybatis的文档，但未能找到关于如何将Domain对象作为参数发送的好例子。

任何人都可以向我展示解决方案

Answer 1

你如何在UserDAO中的CreateNewUserDAO方法中实现。我想对于电话号码你给出错误的值（可能是设置错误的值）。

Answer 2

我可以像这样更改映射器文件后插入记录

我改变了这个

require 'test_helper'

class ConcernedController < ApplicationController
  include Concern

  def action
    render plain: "response", status: :ok
  end
end

class ConcernTest < ActionDispatch::IntegrationTest
  setup do
    @controller = ConcernedController.new

    Rails.application.routes.draw do
      get "/action" => "concerned#action"
      post "/action" => "concerned#action"
    end
  end

  teardown do
    Rails.application.reload_routes!
  end

  test "concern method" do
    post "/action"

    # Test what the concern does

    assert_response :ok
    assert_equal "Response", response.body
  end
end

进入

<insert id="insertUser" useGeneratedKeys="true" keyProperty="id" parameterType="com.greenflight.dto.UserDTO">
    insert into
    tblusers(username,password,email,phone,role,is_active,security_question,securtiy_answer,first_name,last_name)
    values(#{username},#{password},#{email},#{phone},#{role,typeHandler=com.greenflight.typehandlers.StringArrayListTypeHandler},#{is_active},#{security_question},#{securtiy_answer},#{first_name},#{last_name})
</insert>

参数

<insert id="insertUser"  parameterType="com.greenflight.dto.UserDTO">
    insert into
    tblusers(username,password,email,phone,role,is_active,security_question,securtiy_answer,first_name,last_name)
    values(#{username},#{password},#{email},#{phone},#{role,typeHandler=com.greenflight.typehandlers.StringArrayListTypeHandler},#{is_active},#{security_question},#{securtiy_answer},#{first_name},#{last_name})
</insert>

适用于 HashMap 但不适用于POJO不知道原因

POJO作为Mybatis中插入的参数
