SQLServerException：用户“sa”登录失败。 ClientConnectionId：

Question

我正在尝试连接抛出 JDBC，例如：

      Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
      Connection conn = DriverManager.getConnection(SQL_URL, SQL_USER , SQL_PASS);

但是当我执行`getConnection();我得到这个错误：

    com.microsoft.sqlserver.jdbc.SQLServerException: Login failed for user 'sa'. ClientConnectionId:04a4bf33-3489-4279-a6f8-a4da8b7ee567
           at com.microsoft.sqlserver.jdbc.SQLServerException.makeFromDatabaseError(SQLServerException.java:254)[...]

我确定登录是在实例上>安全>登录并使用 SQL Server 身份验证设置，但它仍然失败。

Answer 1

您可能需要启用 SQL Server 身份验证：

请注意：应用此设置后，您需要重新启动服务器。

Answer 2

我已经试过了，但我仍然遇到同样的错误

这是我的主课

@ComponentScan("com.example.student.student.Controller.")
@EnableAdminServer
@EnableJpaRepositories("com.example.student.student.productRepo")
@SpringBootApplication()
//@EnableMongoRepositories(basePackageClasses = CustomerRepository.class)
public class AStudentApplication {

    public static void main(String[] args) {
        SpringApplication.run(AStudentApplication.class, args);
    }

}





Controller




@RestController
@RequestMapping("/")
public class Controller {
    @Autowired
    private ProductRepo productrepo;
    @GetMapping("product")
    public List<Product> getAllProduct()
    {
        List<Product> v = productrepo.findAll();
                return v;

    }
    @PostMapping("/api/v1/Postproduct")
    public Product createProduct(@RequestBody Product product) {
        return productrepo.save(product);
    }
    @RequestMapping("login/1")
    public String welcome() {
        return "login";
    }


}
