sql-server - 找不到适合 jdbc:sqlserver 的驱动程序

Question

我意识到这将被视为重复主题，但我已按照其他相同性质主题中的推荐步骤进行操作，但没有成功。

我正在使用 GGTS 3.6.4

圣杯 2.3.0
jdk1.7.0_80
Groovy 编译器级别 2.3
微软 SQL 服务器 2012

我有一个 grails 应用程序，它使用 Apache Shiro 对登录到 LDAP 服务器的用户进行身份验证，并且我有以下代码（在 Shiro 生成的AuthController.groovy）中尝试在会话中存储来自外部数据库的一些信息。（注意：关于用户名、密码和数据库名称，出于隐私原因，我在这里全部更改了）

def signIn = {
    Subject subject = SecurityUtils.getSubject();
    String lowerCaseUserName=params.username.toLowerCase();
    def authToken = new UsernamePasswordToken(lowerCaseUserName, params.password)

    // Support for "remember me"
    if (params.rememberMe) {
        authToken.rememberMe = true
    }

    try{
        subject.login(authToken)

        if (subject.isAuthenticated()) 
        {
            session.username = lowerCaseUserName

            // Attempting to get employee id from MS SQL
            Sql Database = Sql.newInstance(
                'jdbc:sqlserver://myserver;DatabaseName=mydatabase',
                'user',
                'password',
                'com.microsoft.sqlserver.jdbc.SQLServerDriver'
            );
            Database.eachRow('select empid from table_name where username=${session.username}') { row ->
                session.empid = row.empid
            }
            Database.close();   

            def targetUri = params.targetUri ?: "/home"
            log.info "Redirecting to '${targetUri}'."
            redirect(uri: targetUri)
        }
    }
    ...
}

但是，我收到以下错误

SQLException occurred when processing request: [POST] /app/auth/signIn - parameters:
username: user
_rememberMe: 
targetUri: 
password: ***
No suitable driver found for jdbc:sqlserver://myserver;DatabaseName=mydatabase. Stacktrace follows:

我尝试了以下但没有成功：

将 sqljdbc4.jar 添加到 /app/lib/
手动将 /app/lib/ 添加到类路径（通过 .classpath）
Properties通过>>将 sqljdbc4.jar 添加到类路径Java Build Path中Add JARs

我已经用 sqljdbc4.jar、sqljdbc.jar 和 sqlserverjdbc.jar 及其每一个组合尝试了这些变体。

我基本上被卡住了。我在这里或其他地方读到的所有修复都不能解决我的错误。任何帮助将不胜感激！

编辑1：Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver")在调用上方添加newInstance会产生以下错误：

ClassNotFoundException occurred when processing request: [POST] /app/auth/signIn - parameters:

_rememberMe:

这是向前、向后迈出的一步，还是我们在原地踏步？

编辑2：我最终要做的就是把我改成DataSource.groovy这个

dataSource {
    pooled = true
}
hibernate {
    cache.use_second_level_cache = true
    cache.use_query_cache = false
    cache.region.factory_class = 'net.sf.ehcache.hibernate.EhCacheRegionFactory' // Hibernate 3
    //cache.region.factory_class = 'org.hibernate.cache.ehcache.EhCacheRegionFactory' // Hibernate 4
}

// environment specific settings
environments {
    development {
        dataSource {
            dbCreate = "validate"
            url = "jdbc:sqlserver://myserver:1433;databaseName=mydatabase;"
            driverClassName = "com.microsoft.sqlserver.jdbc.SQLServerDriver"
            username = "myusername"
            password = "mypassword"
        }
    }
....
}

并将我的AuthController.groovy数据访问权限更改为

    try{
        subject.login(authToken)
        if (subject.isAuthenticated()) 
        {
            ShiroUser currentUser = new ShiroUser()

            def targetUri = params.targetUri ?: "/home"
            log.info "Redirecting to '${targetUri}'."
            redirect(uri: targetUri)
        }
    }

我已经使用修改后的ShiroUser.groovy文件成功访问了我的数据库

class ShiroUser {

    static hasMany = [ roles: ShiroRole, permissions: String ]

    User_Data userData;

    static constraints = {
    }

    def getUsername() {
        return userData.username
    }
}

User_Data.groovy一个新的域类在哪里包含

class User_Data {

    static mapping = {
        table "mytablename"
    }
    ...
}

所以现在我要搞砸方法了！不知道为什么 JDBC 的东西没有成功，但 GORM 是我现在要走的路。

您肯定需要将 sqljdbc4.jar 添加到您已经完成的 /app/lib/ 中。

您是否尝试将数据库连接添加到 BuildConfig.groovy

dataSource {
        dbCreate = "update" // one of 'create', 'create-drop', 'update', 'validate', ''
        driverClassName = "com.microsoft.sqlserver.jdbc.SQLServerDriver"
        dialect = "org.hibernate.dialect.SQLServerDialect"
        url = "jdbc:sqlserver://localhost:1433;databaseName=dbName"
        username = "sa"
        password = ""
    }

还要确保 SQL 服务器配置为接受端口 1433 上的连接。默认情况下它是禁用的。
