找不到适用于jdbc：sqlserver的驱动程序

Question

I realize this is what would be considered a duplicate topic, but I have followed the recommended steps in the other topics of this same nature with no success.

I am using GGTS 3.6.4 with

• Grails 2.3.0
• jdk1.7.0_80
• Groovy compiler level 2.3
• Microsoft SQL Server 2012

I have a grails-app which authenticates users logging in against an LDAP server with Apache Shiro and I have the following code (in the Shiro generated AuthController.groovy ) to try and store some information from an external database in the session. (Note: With regards to usernames, passwords, and database names, I've changed all of them here for privacy reasons)

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)
        }
    }
    ...
}

However, I get the following error

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:

I have tried the following with no success:

• Added sqljdbc4.jar to /app/lib/
• Manually added /app/lib/ to classpath (via .classpath)
• Added sqljdbc4.jar to the classpath via the Properties > Java Build Path > Add JARs

I've tried these variations with sqljdbc4.jar, sqljdbc.jar, and sqlserverjdbc.jar and every combo thereof.

I'm basically stuck. None of the fixes I've read on here, or elsewhere, solve my error. Any help would be greatly appreciated!

Edit 1: Adding Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver") above the newInstance call produces the following errors:

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

_rememberMe:

Is this a step forward, backward, or are we running in place?

Edit 2: What I ended up having to do was change my DataSource.groovy to this

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"
        }
    }
....
}

and changed my AuthController.groovy data access to

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

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

and I have successfully accessed my DB with a modified ShiroUser.groovy file

class ShiroUser {

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

    User_Data userData;

    static constraints = {
    }

    def getUsername() {
        return userData.username
    }
}

where User_Data.groovy is a new domain class containing

class User_Data {

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

So now I'm onto messing with methods! Not sure why JDBC stuff didn't work out, but GORM is the path I'm taking now.

Answer 1

you definitely need to add sqljdbc4.jar to /app/lib/ which you have already done.

have you tried adding database connection to the 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 = ""
    }

Also make sure the SQL server is configured to accept connection on port 1433. It is disabled by default.
