工作中遇到的问题--实现程序运行时就加载CustomerSetting的第二种方法

写一个自定义注解

@Target({ElementType.FIELD, ElementType.PARAMETER, ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
@Qualifier
public @interface CurrentCustomerSettings {

}

在web初始化类中添加：

@Configuration
@Order(3)
@EnableWebMvcSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class MFGWebSecurityConfigurerAdapter extends
       AWebSecurityConfigurerAdapter {

   @Autowired
   private UserRepository userRepository;

   @Autowired
   private CustomerSettingsRepository customerSettingsRepository;

   @Override
   protected void configure(HttpSecurity httpSecurity) throws Exception {
       httpSecurity
               .formLogin()
               .successHandler(
                       new SavedRequestAwareAuthenticationSuccessHandler())
               .loginPage("/login").permitAll().failureUrl("/login-error")
               .defaultSuccessUrl("/").and().logout()
               .logoutRequestMatcher(new AntPathRequestMatcher("/logout"))
               .logoutSuccessUrl("/logged-out").permitAll().and().rememberMe()
               .key(SECURITY_TOKEN)
               .tokenRepository(persistentTokenRepository())
               .tokenValiditySeconds(mfgSettings.getRememberMeTokenValidity())
               .and().sessionManagement().maximumSessions(1)
               .sessionRegistry(sessionRegistry).and().sessionFixation()
               .migrateSession().and().authorizeRequests().anyRequest()
               .authenticated();
   }

   @Bean
   public PersistentTokenRepository persistentTokenRepository() {
       JdbcTokenRepositoryImpl tokenRepository = new JdbcTokenRepositoryImpl();
       tokenRepository.setDataSource(dataSource);
       return tokenRepository;
   }

   @Bean
   @LoggedInUser
   @Scope(value = WebApplicationContext.SCOPE_SESSION, proxyMode = ScopedProxyMode.TARGET_CLASS)
   @Transactional(readOnly = true)
   public User getLoggedInUser() {
       Authentication authentication = SecurityContextHolder.getContext()
               .getAuthentication();
       if (authentication != null
               && !(authentication instanceof AnonymousAuthenticationToken)
               && authentication.isAuthenticated())
           return userRepository.findByLogin(authentication.getName());
       return null;
   }

   @Bean
   @SystemUser
   @Scope(value = WebApplicationContext.SCOPE_APPLICATION, proxyMode = ScopedProxyMode.NO)
   @Transactional(readOnly = true)
   public User getSystemUser() {
       return userRepository.findByLogin(Constants.SYSTEM_USER);
   }

   @Bean

    @CurrentCustomerSettings
   @Scope(value = WebApplicationContext.SCOPE_APPLICATION, proxyMode = ScopedProxyMode.NO)
   public CustomerSettings customerSettings() {
       return customerSettingsRepository.findAll().get(0);
   }

以后在注入的时候，只需要写：

@CurrentCustomerSettings

@Autowired

CustomerSettings customerSettings;
