首先在项目运行时就初始化CustomerSettings的值，采用@Bean，默认是singtone模式，只会加载一次。
@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
public CustomerSettings customerSettings() {
return customerSettingsRepository.findAll().get(0);
}
}
为了能够在CustomerSettings发生改变时，对相关的值进行实时更新，在CustomerService中添加更新后的操作方法：
@Override
protected void afterUpdate(CustomerSettings t) {
customerSettings.editFrom(t);
}
@Override
protected void afterEdit(CustomerSettings t) {
customerSettings.editFrom(t);
}
另外：enitForm方法是写在CustomerSettings.java这个实体类中的，这样在更新时就能实现对其中元素的部分更新，避免以前实训中有些元素没更新就会被置空，需要每次都先查询再手动部分更新的情况。
以下是这个实体中使用enitForm的案例：
