此Spring Boot应用程序依赖于其他三个@Configuration类：AppConfig，SecurityConfig和AuthServerConfig . 对于此问题，SecurityConfig和AppConfig类是相关的（它们包括对PasswordEncoder bean的引用） .

AppConfig（部分）

@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; @Bean public PasswordEncoder passwordEncoder() { return new BCryptPasswordEncoder(); /// more code here 

SecurityConfig：

@Configuration@EnableGlobalMethodSecurity(prePostEnabled = true)@EnableWebSecuritypublic class SecurityConfig extends WebSecurityConfigurerAdapter { @Autowired private OAuthUserDetailsService userService; @Autowired private PasswordEncoder passwordEncoder; @Bean @Override protected AuthenticationManager authenticationManager() throws Exception { return super.authenticationManager(); // Hash password @Override protected void configure(AuthenticationManagerBuilder auth) throws Exception { auth.userDetailsService(userService) .passwordEncoder(passwordEncoder); @Override protected void configure(HttpSecurity http) throws Exception { http .sessionManagement() .sessionCreationPolicy(SessionCreationPolicy.STATELESS) .and() .httpBasic() .realmName( test ) .and() .csrf() .disable();

UserRepository类非常简单：

public interface UserRepository extends CrudRepository OAuthUser, Long { public OAuthUser findByUserName(String name);

如何确保为我的测试找到所有必需的bean？谢谢 .

编辑：

如果我尝试在我的测试类中@Autowire bean，我会收到同样的错误 .

@Autowired private PasswordEncoder passwordEncoder;
