Java连接到SqlServer数据库

Question

我正在尝试使用Eclipse连接到SQL Server数据库，但这给了我错误：

Cannot open database "AdventureWorks2012" requested by the login. The login failed. 

Answer 1

Since you are using integratedSecurity=true it means that you windows account is not allowed to access AdventureWorks2012 database. You need to grant the Windows account you are logged in (or running Eclipse) the database access rights. You can follow To configure database access docs to grant your Windows account access:

1. On the computer that is running SQL Server, start SQL Server Management Studio. In the Registered Servers pane, double-click SQL Server.

2. In the object explorer pane, expand SQL Server, expand the Security folder, right-click Logins, and then click New Login.

3. In the Login – New dialog box, specify either Windows Authentication or SQL Server Authentication mode.

4. If you are using Windows Authentication, enter a logon name and select either the Grant Access or the Deny Access option.

5. If you are using SQL Server Authentication, type a logon name and password, and then confirm the password.

6. In the left pane, click Database Access.

7. In the right pane, select the Permit check box for the databases you are granting access to, and then click OK.

If you want to connect by specifying username and password use integratedSecurity=false and supply username and password as shown in the Establishing a Connection docs:

String jdbcUrl = "jdbc:sqlserver:...";
Properties props = new Properties();
props.put("user", <database username>);
props.put("password", <database password>);
try (Connection conn = DriverManager.getConnection(jdbcUrl, props)) {
  ...
}
