我遇到了 Grails数据库迁移插件生成的异常。
在JIRA中,它说这是一个不会修复的错误。
但是,我想将 Spring Security 与默认数据库 H2 一起使用,因为它很容易用来制作一个简单的应用程序。
除了将数据库更改为 MYSQL 或 ORACLE 之外,我该如何避免此错误?
更新
在JIRA中的解决方案之后,我在User.groovy中将发生错误的列的名称password
更改为passwd
。
User.groovy的一部分如下所示。
String username
String password
static transients = ['springSecurityService']
static constraints = {
username blank: false, unique: true
password blank: false
}
static mapping = {
password column: '`passwd`'
}
运行命令gradle grails-dbm-gorm-diff -PgrailsArgs="2015-5-23-first-diff.groovy --add"
后,我收到如下错误。

如JIRA所述,解决方案如下:
这是由逃避密码的反引号造成的。在 生成的用户类。 '密码'在某些人中是保留的词 数据库因此默认情况下脚本会将其转义,因为它不是a 保留字它没有效果。所以要么删除"密码列: '
password
'"如果它不是保留字,或将其改为a 没有反引号的非保留字,如果是,例如, "密码栏: ' passwd的'"
这意味着您需要修改User
域类。
更新您的域类应如下所示:
String username
String password
static transients = ['springSecurityService']
static constraints = {
username blank: false, unique: true
password blank: false
}
static mapping = {
// NOTICE THE FOLLOWING FIELD DOES NOT HAVE BACKTICKS!
password column: 'passwd'
}

我也遇到了这个问题,但是能够通过改变来修复它:
grails test dbm-gorm-diff ...
到
SELECT TIMESTAMP(your_ts_str + "01") AS ts
我的开发环境(默认)设置为使用H2数据库,但我的测试环境(此命令所针对的环境)设置为使用postgres。
