< method>中方法setUserService的参数0设置为0.需要类型为< service>的bean.找不到 [英] Parameter 0 of method setUserService in <method> required a bean of type <service> that could not be found

问题描述

我已经解决了这个问题，找不到正在发生的事情....尝试使用@ComponentScan，尝试命名我的服务，似乎没有任何作用.

I have been through this issue and couldn't find what is going on.... tried to @ComponentScan, tried to name my services, none seems to work.

Description:

Parameter 0 of method setUserService in com.ipayso.services.security.UserDetailsServiceImpl required a bean of type 'com.ipayso.services.UserService' that could not be found.


Action:

Consider defining a bean of type 'com.ipayso.services.UserService' in your configuration.

我的SecurityConfiguration:

package com.project.config
@Configuration
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

private AuthenticationProvider authenticationProvider;

@Autowired
@Qualifier("daoAuthenticationProvider")
public void setAuthenticationProvider(AuthenticationProvider authenticationProvider) {
    this.authenticationProvider = authenticationProvider;
}

@Bean
public PasswordEncoder passwordEncoder(StrongPasswordEncryptor passwordEncryptor){
    PasswordEncoder passwordEncoder = new PasswordEncoder();
    passwordEncoder.setPasswordEncryptor(passwordEncryptor);
    return passwordEncoder;
}

@Bean
public DaoAuthenticationProvider daoAuthenticationProvider(PasswordEncoder passwordEncoder, UserDetailsService userDetailsService){
    DaoAuthenticationProvider daoAuthenticationProvider = new DaoAuthenticationProvider();
    daoAuthenticationProvider.setPasswordEncoder(passwordEncoder);
    daoAuthenticationProvider.setUserDetailsService(userDetailsService);
    return daoAuthenticationProvider;
}

@Autowired
public void configureAuthManager(AuthenticationManagerBuilder authenticationManagerBuilder){
    authenticationManagerBuilder.authenticationProvider(authenticationProvider);
}

@Override
protected void configure(HttpSecurity httpSecurity) throws Exception {
    httpSecurity
            .authorizeRequests().antMatchers("/", "/home", "/login", "/signup").permitAll()
        .and()
            .formLogin()
            .loginPage("/login")
            .failureUrl("/login-error")
        .and()
            .logout()
            .logoutSuccessUrl("/home");
}
}

我的UserDetailServiceImpl:

package com.project.service.security
@Service("userDetailsService")
public class UserDetailsServiceImpl implements UserDetailsService {

private UserService userService;
private Converter<User, UserDetails> userUserDetailsConverter;

@Autowired
@Qualifier(value = "userService")
public void setUserService(UserService userService) {
    this.userService = userService;
}

@Autowired
@Qualifier(value = "userToUserDetails")
public void setUserUserDetailsConverter(Converter<User, UserDetails> userUserDetailsConverter) {
    this.userUserDetailsConverter = userUserDetailsConverter;
}

@Override
public UserDetails loadUserByUsername(String email) throws UsernameNotFoundException {
    return userUserDetailsConverter.convert(userService.findByEmail(email));
}
}

我的UserServiceImpl:

package com.project.service
@Service
@Profile("springdatajpa")
public class UserServiceImpl implements UserService{

private UserRepository userRepository;

@Autowired
public void setUserRepository(UserRepository userRepository) {
    this.userRepository = userRepository;
 }

private EncryptionService encryptionService;

@Autowired
public void setEncryptionService(EncryptionService encryptionService) {
    this.encryptionService = encryptionService;
}


@Override
public List<?> listAll() {
    List<User> users = new ArrayList<>();
    userRepository.findAll().forEach(users::add); //fun with Java 8
    return users;
}

@Override
public User getById(Integer id) {
    return userRepository.findOne(id);
}

@Override
public User saveOrUpdate(User domainObject) {
    if(domainObject.getPassword() != null){
        domainObject.setEncryptedPassword(encryptionService.encryptString(domainObject.getPassword()));
    }
    return userRepository.save(domainObject);
}
@Override
@Transactional
public void delete(Integer id) {
    userRepository.delete(id);
}

@Override
public User findByEmail(String email) {
    return userRepository.findByEmail(email);
}
}

我的CommonBeanConfig:

package com.project.config
@Configuration
public class CommonBeanConfig {

@Bean
public StrongPasswordEncryptor strongEncryptor(){
    StrongPasswordEncryptor encryptor = new StrongPasswordEncryptor();
    return encryptor;
}
}

我的App:

package com.project
@SpringBootApplication
public class App extends SpringBootServletInitializer{

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

@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
    return application.sources(applicationClass);
}

private static Class<App> applicationClass = App.class;
}

我的RepositoryConfiguration:

package com.project.config
@Configuration
@EnableAutoConfiguration
@EntityScan(basePackages = {"com.ipayso.model"})
@EnableJpaRepositories(basePackages = {"com.ipayso.repositories"})
@EnableTransactionManagement
public class RepositoryConfiguration {

}

推荐答案

您要在此处使用@Qualifier(value = "userService")查找UserService:

@Autowired
@Qualifier(value = "userService")
public void setUserService(UserService userService) {
    this.userService = userService;
}

但是您没有它，因为您的UserServiceImpl注释为@Service而未提供其ID.

but you don't have it, since your UserServiceImpl annotated as @Service without providing it's id.

要将id设置为您的UserServiceImpl，您需要使用@Service("userService")对其进行注释.但是，如果您只有一个UserService实现，则只需从设置器中删除@Qualifier(value = "userService")，因为它是多余的.

To set id to your your UserServiceImpl, you need to annotate it with @Service("userService"). But if you have a single UserService implementation, just delete @Qualifier(value = "userService") from setter, because it's redundant.

在我看来，这不是唯一一个必须删除@Qualifier的地方.

And it seems to me, it's not the only place, where you have to remove a @Qualifier.

@Qualifier批注来选择确切的bean.如果只有一个，则不需要使用它.

@Qualifier annotation is needed to select exact bean if you have a number of beans of the same type. If you have a single one, you don't need to use it.
