Question

我已经为我的应用程序提供了基于JWT令牌的身份验证机制，现在仅针对API，我需要使用oracle数据库添加身份验证：我的应用程序用户还将是DB oracle用户。

我想先不知道数据源的用户名和密码来启动spring boot应用程序，它将在前端进行身份验证后恢复。

我第一次希望应用程序在不连接任何数据库的情况下启动，但是一旦用户尝试进行身份验证，我们将使用其用户名和密码来创建与数据库的连接。目的是我们希望从oracle数据库的身份验证中受益。

当用户尝试进行身份验证时，我大惊小怪地收到了这个错误

“消息”：“无法获取JDBC连接；嵌套的异常是org.hibernate.exception.GenericJDBCException：无法获取JDBC连接”，

DataSourceConfig

@Component

public class DataSourceConfig  {

    @NotNull
    private String username;
    @NotNull
    private String password;
    @NotNull
    private String url;

    public void setUsername(String username) {
        this.username = username;
    }
    public void setPassword(String password) { this.password = password; }
    public void setUrl(String url) { this.url = url; }

    public String getUrl() { return url; }
    public String getUsername() {
        return username;
    }
    public String getPassword() {
        return password;
    }

    @Bean
    public DataSource dataSource() throws SQLException {
        OracleDataSource dataSource = new OracleDataSource();
        dataSource.setUser(username);
        dataSource.setPassword(password);
        dataSource.setURL(url);
        dataSource.setImplicitCachingEnabled(true);
        dataSource.setFastConnectionFailoverEnabled(true);
        return dataSource;
    }

AuthenticationController

@RestController
@CrossOrigin
@RequestMapping("/Authentication")
public class AuthenticationController {
    @Autowired
    private AuthenticationManager authenticationManager;
    @Autowired
    private JwtTokenUtil jwtTokenUtil;
    @Autowired
    private UserService userDetailsService;
    @Autowired
    private MenuService menuservice;

    @Autowired
    private Environment env;
    @Autowired
    private DataSourceConfig dataSourceConfig;

    @RequestMapping(method = RequestMethod.POST,consumes = "application/x-www-form-urlencoded")
    public ResponseEntity<?> createAuthenticationToken(JwtRequest authenticationRequest) throws Exception {

        dataSourceConfig.setUsername(authenticationRequest.getUsername());
        dataSourceConfig.setPassword(authenticationRequest.getPassword());
        dataSourceConfig.setUrl(env.getProperty("spring.datasource.url"));
        dataSourceConfig.dataSource();

        String url = env.getProperty("spring.datasource.url");
      
        User userconnected 
        =userDetailsService.getUserbyUsernameAndPassword(authenticationRequest.getUsername(),
                authenticationRequest.getPassword(),url);
        if (userconnected != null){
          ModelDTO model = menuservice.GetModel(userconnected);
    
            final UserDetails userDetails = userDetailsService
                    .loadUserByUsername(authenticationRequest.getUsername());
            String ConnectionString = "url=" + url + ";user=" + authenticationRequest.getUsername() + ";password=" + authenticationRequest.getPassword();
            final String token = jwtTokenUtil.generateToken(userDetails, ConnectionString);
    
            return ResponseEntity.ok(new JwtResponse(token,userconnected.getUsername(),model));
        }
        else{
            return ResponseEntity.ok("Utilisateur/ ou Mot de passe incorrecte");
        }
    }
