我的系统里有两种用户，对应数据库两张表，所以必须自定义provider 和 AuthenticationToken，这样才能走到匹配自定义的UserDetailsService。
必须自定义原因在于，security内部是遍历prodvider，根据其support 方法判断是否匹配Controller提交的token，然后走provider注入的认证service方法。
用用户名和密码构造AuthenticationToken 并提交给 authenticationManager，
authenticationManager.authenticate(new UsernamePasswordAuthenticationToken(username, password));
会遍历自定义和内置provider，根据provider的support方法判断入参Token所匹配provider
public boolean supports(Class<?> authentication) {
return (EcStaffUsernamePasswordAuthenticationToken.class.isAssignableFrom(authentication));
}
过程中会调用UserDetailsService.loadUserByUsername，这个service可以在SecurityConfig中配置注入到provider
需要我们自己查询数据库中用户对象，返回对象UserDetails，
我返回的是LoginUser （ implements UserDetails ），这样把数据库查出来用户对象加进去，方便前台Controller使用
@Override public UserDetails loadUserByUsername(String username) //查询数据库
包括判断密码是否匹配等，如果密码不匹配或帐号过期等spring会上抛异常到Controller
回到Controller的方法，并返回authentication。对于异常需要自己捕获，详情可参见后面的代码。
authentication = authenticationManager.authenticate(new UsernamePasswordAuthenticationToken(username, password)); LoginUser loginUser = (LoginUser) authentication.getPrincipal();
说明：
大部分人是在流程最前面使用filter实现各种校验，而我的项目全部是前后端分离，所以我的filter只校验token有效性，我把各种非空校验放在controller。

因为有两种用户sysuser和ecstaff，为了基于这个LoginUser统一提供getUsername方法，让他们继承或实现统一BaseUser，
可以不统一封装因为LoginUser构造方法入参是object , 即LoginUser(Object user, Set<String> permissions)

注意这里换了security提供的AuthToken，这个token会调用security内部的DaoAuthenticationProvider进行认证
// 用户验证
Authentication authentication = null;
try
{
// 该方法会去调用UserDetailsServiceImpl.loadUserByUsername
// 该方式使用的security内置token会使用内置DaoAuthenticationProvider认证
// UserDetailsServiceImpl是在security config中配置的
authentication = authenticationManager
.authenticate(new UsernamePasswordAuthenticationToken(username, password));
}
catch (Exception e)
{
if (e instanceof BadCredentialsException)
{
throw new UserPasswordNotMatchException();
}
else
{
throw new CustomException(e.getMessage());
}
}
LoginUser loginUser = (LoginUser) authentication.getPrincipal();// 该方法会去调用
可参照上述service写，查询另一张用户表即可，返回UserDetails
