二、异常信息分析

1.insert语句执行失败

    异常显示就是insert插入sql语句执行错误导致添加记录到数据库失败；

    根本原因就是Field 'userID' doesn't have a default value；

    字段userID没有设置默认值；

    下面该表的create语句中确实没有给userID设置默认值；

CREATE TABLE `t_user` (
  `userID` int(11) NOT NULL,
  `uname` varchar(20) default NULL,
  `userAddress` varchar(100) default NULL,
  `userBirth` varchar(10) default NULL,
  `userEmail` varchar(50) default NULL,
  `userGender` int(11) default NULL,
  `userName` varchar(20) default NULL,
  `userPassword` varchar(150) default NULL,
  `userPhone` varchar(255) default NULL,
  PRIMARY KEY  (`userID`)
);

    导致insert语句对应的userID字段没有插入数据，而该字段不允许为null导致的；

Hibernate: insert into t_user (uname, userAddress, userBirth, userEmail, userGender, userName, userPassword, userPhone) values (?, ?, ?, ?, ?, ?, ?, ?)

三、解决异常

3-1.给字段设置默认值

    这种问题简单的解决办法就是设置默认值,但是当前字段userID是主键不能设置默认值；

`userAddress` varchar(100) default '阿拉加斯加'

3-2.Hibernate配置检查

    那可能是Hibernate配置出现了问题；然后找到当前表对应的Entity实体类

    字段userID的配置

	@Id
	@GeneratedValue(strategy = IDENTITY)
	@Column(name = "userID", unique = true, nullable = false)
	public Integer getUserId() {
		return this.userId;
	}

    该字段设置了自增策略，指定不可为空，且是唯一的；

    感觉没啥问题；再次测试新增一条记录还是失败；

3-3.数据库中表t_user的修改

    然后就从数据表这里入手；

    将当t_user的userID修改为自增

alter table t_user modify userID int auto_increment;

    因为该字段有外键约束不允许修改；

    索性就把表删了；新建表t_user；直接在设置字段自增且不为空；然后新增一条记录成功了；

CREATE TABLE `t_user` (
  `userID` int(11) NOT NULL auto_increment,
  `uname` varchar(20) default NULL,
  `userAddress` varchar(100) default NULL,
  `userBirth` varchar(10) default NULL,
  `userEmail` varchar(50) default NULL,
  `userGender` int(11) default NULL,
  `userName` varchar(20) default NULL,
  `userPassword` varchar(150) default NULL,
  `userPhone` varchar(255) default NULL,
  PRIMARY KEY  (`userID`)
);

 



四、其他解决方法

1.修改mysql配置。打开my.ini，查找sql-mode="STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"修改为sql-mode="NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"然后重启MYSQL

2.设置默认值即可，当然这个字段不是主键的情况下；

3.MySQL 5 uses a strict mode which needs to be disabled. In Windows, Goto Start-->Programs-->MySQL->MySQL Instance Config Wizard. Follow through the Reconfigure Instance option-->Detailed Configuration-->Continue Next a few screens. At the bottom under Enable TCP/IP option there is 'Enable Strict Mode'. Deslect this option (no tick). Save changes and MySQL will restart.

                                 如何获取支付宝UserId

1、登录支付宝网页版

      进入支付宝官网alipay.com,扫码登录或者账号密码登录



登陆成功后自动跳转到个人首页：



2、获取UserId

   在主页页面上鼠标右击或者CTRL+U查看网页源码，在源码页面CTRL+F 查找：userId，结果如下图：

调微信支付时中需要将userid转换成openid

阅读文档(https://work.weixin.qq.com/api/doc#90000/90135/90202)后开始调用，

结果接口返回：

{"errcode":40003,"errmsg":"invalid userid, hint: [1563539598_4_6ae561db56e26aba05e01ee837ef724c], from ip: 116.52.237.66, more info at https://open.work.weixin.qq.com/devtool/query?e=40003"}

检查入参和POST方式均没有问题，网上搜索有人通过接口调试工具是可以正常返回openid的

https://segmentfault.com/q/1010000014811463/a-1020000014850318

https://blog.csdn.net/a545132569/article/details/89512913

于是按照博客中的方式，也去腾讯提供的调试页面测试https://work.weixin.qq.com/api/devtools/devtool.php



发现可以正常获取openid

博客里的哥们说自己通过chrome发现腾讯提供的调试页面请求的地址和文档中的地址不一样，他在自己的代码中把请求地址改成和调试页面中一样的地址就ok了，但是我照做了还是不行。于是就开始用postman模拟请求，后来发现post中body选项下选form-data，得到的响应和我代码调用时获取的一样，都是题目中的errcode:40003,errmsg:invalid userid，但是body选项下选raw的时候就可以正常获取openid了。



 

这下就真相大白了，我代码里用httpclient发起的post的请求时和postman里选form-data的时候是一样的，弄清了这两种方式的区别，为httpclient发起请求增加了raw这种形式的调用，问题解决。

httpclient调用参考博客：https://www.cnblogs.com/zhangfei/p/5099036.html

controller获取userid
HttpSession session = request.getSession(); I
nteger userId = (Integer)session.getAttribute("userId");
