我正在嘗試使用 Spring Boot 2 創建 OAuth2 授權服務器。但是，每當我嘗試啟動我的應用程序時，我都會收到一個錯誤：Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.2018-08-17 08:17:53.946 ERROR 38996 --- [ restartedMain] o.s.boot.SpringApplication : Application run failed從堆棧跟蹤來看，問題的根源似乎在于創建entityManagerFactorybean。但是，我無法弄清楚為什么這會成為一個問題。問題始于我的 AppConfig，它引用了在我的 AuthServerConfig 中找到的JwtAccessTokenConverter： @Configurationpublic class AppConfig { @Value("${spring.datasource.url}") private String datasourceUrl; @Value("${spring.datasource.driverClassName}") private String dbDriverClassName; @Value("${spring.datasource.username}") private String dbUsername; @Value("${spring.datasource.password}") private String dbPassword; @Autowired JwtAccessTokenConverter accessTokenConverter; @Bean public PasswordEncoder passwordEncoder() { return new BCryptPasswordEncoder(); } @Bean public ModelMapper modelMapper() { ModelMapper mapper = new ModelMapper(); return mapper; } @Bean public DataSource dataSource() { final DriverManagerDataSource dataSource = new DriverManagerDataSource(); dataSource.setDriverClassName(dbDriverClassName); dataSource.setUrl(datasourceUrl); dataSource.setUsername(dbUsername); dataSource.setPassword(dbPassword); return dataSource; } @Bean public TokenStore tokenStore() { return new JwtTokenStore(accessTokenConverter); }}

將 移動DataSource到僅包含DataSourcebean 和環境值的單獨配置文件中。我相信你在某處有一個循環依賴JwtAccessTokenConverter。
當我遵循可能相同的教程時，我遇到了類似的問題。
@Configuration
public class DataSourceConfig {
@Value("${spring.datasource.url}")
private String datasourceUrl;
@Value("${spring.datasource.driverClassName}")
private String dbDriverClassName;
@Value("${spring.datasource.username}")
private String dbUsername;
@Value("${spring.datasource.password}")
private String dbPassword;
@Bean
public DataSource dataSource() {
final DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setDriverClassName(dbDriverClassName);
dataSource.setUrl(datasourceUrl);
dataSource.setUsername(dbUsername);
dataSource.setPassword(dbPassword);
return dataSource;
}
}
