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;
