#### 项目结构

**security**
> * 参照spring security reference写的一个简单demo，没有参考价值，可以略过

**security-ajax**
> * 抛弃默认登录方式，使用ajax方式登录，因此自定义增加了AuthenticationSuccessHandler和AuthenticationFailureHandler用来返回自定义json
```C
/**
 * @author dongsilin
 * @version 2018/4/8.
 *          登陆成功后的处理
 */
@Slf4j
@Component
public final class CustomAuthenticationSuccessHandler extends SimpleUrlAuthenticationSuccessHandler {

@Override
    public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws ServletException, IOException {
        log.info("*******************AuthenticationSuccessHandler");
        WebUtil.output(response, RestResponse.buildSuccess(), WebUtil.ResponseOutputType.JSON);
    }

}
```
```C
/**
 * @author dongsilin
 * @version 2018/4/8.
 *          登陆失败后的处理
 */
@Slf4j
@Component
public final class CustomAuthenticationFailureHandler extends SimpleUrlAuthenticationFailureHandler {

@Override
    public void onAuthenticationFailure(HttpServletRequest request, HttpServletResponse response, AuthenticationException e) throws IOException, ServletException {
        log.info("*******************AuthenticationFailureHandler");
        if (e instanceof CaptchaAuthenticationException) {
            WebUtil.output(response, RestResponse.buildFail(e.getMessage()), WebUtil.ResponseOutputType.JSON);
        } else if (e instanceof UsernameNotFoundException) {
            WebUtil.output(response, RestResponse.buildFail("用户名不存在"), WebUtil.ResponseOutputType.JSON);
        } else if (e instanceof BadCredentialsException) {
            WebUtil.output(response, RestResponse.buildFail("密码错误"), WebUtil.ResponseOutputType.JSON);
        } else {
            WebUtil.output(response, RestResponse.buildFail("操作失败"), WebUtil.ResponseOutputType.JSON);
        }
    }

}
```
> * 默认情况下DaoAuthenticationProvider会丢弃UsernameNotFoundException(用户名错误)，原因在于其参数hideUserNotFoundExceptions=true，把UsernameNotFoundException给hide掉了，请看如下源码。因此自定义AuthenticationProvider继承自DaoAuthenticationProvider，把hideUserNotFoundExceptions改为false
```C
//org.springframework.security.authentication.dao.AbstractUserDetailsAuthenticationProvider  第62行
try {
    user = this.retrieveUser(username, (UsernamePasswordAuthenticationToken)authentication);
} catch (UsernameNotFoundException var6) {
    this.logger.debug("User \'" + username + "\' not found");
    if(this.hideUserNotFoundExceptions) {
        throw new BadCredentialsException(this.messages.getMessage("AbstractUserDetailsAuthenticationProvider.badCredentials", "Bad credentials"));
    }
    throw var6;
}
```
```C
@Slf4j
@Component
public final class CustomAuthenticationProvider extends DaoAuthenticationProvider {

@Autowired
    private UserDetailsService userDetailsService;

@PostConstruct
    public void init() {
        setUserDetailsService(userDetailsService);
        setPasswordEncoder(new BCryptPasswordEncoder(8));
        setHideUserNotFoundExceptions(false);
    }
}
```
> * 增加登录验证码校验Filter: CustomCaptchaVerifyFilter，见项目代码

**security-ajax-rememberme**
> * 在security-ajax中增加rememberme功能
> * 提供RememberMeAuthenticationFilter bean和RememberMeAuthenticationProvider bean
> * 在CustomCaptchaVerifyFilter中设置rememberMeServices：setRememberMeServices(rememberMeServices)
> * 详细代码请clone再查看

**oauth2**
> * 待完善

**oauth2-sso-server**
> * 待完善
