如果您查看UsernamePasswordAuthenticationFilter 中的代码，则有setDetails 方法。
来自docs：
提供以便子类可以配置放入
身份验证请求的 details 属性。
从这里开始的想法
Provision to change ldap/Ad provider url at run time
您可以在此处设置 authtype 之类的详细信息并使用身份验证提供程序，但要实现您喜欢的事情，需要做更多的工作。
添加详细信息，希望对您有所帮助。
CustomUsernamePasswordAuthenticationFilter.java
import javax.servlet.http.HttpServletRequest;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.authentication.AuthenticationDetailsSource;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter;
import org.springframework.stereotype.Component;
@Component
public class CustomUsernamePasswordAuthenticationFilter extends UsernamePasswordAuthenticationFilter {
private static final Logger logger = LoggerFactory.getLogger(CustomUsernamePasswordAuthenticationFilter.class);
@Autowired
@Override
public void setAuthenticationManager(AuthenticationManager authenticationManager) {
// TODO Auto-generated method stub
super.setAuthenticationManager(authenticationManager);
}
@Autowired
@Override
public void setAuthenticationDetailsSource(
AuthenticationDetailsSource<HttpServletRequest, ?> authenticationDetailsSource) {
super.setAuthenticationDetailsSource(authenticationDetailsSource);
}
@Override
protected void setDetails(HttpServletRequest request, UsernamePasswordAuthenticationToken authRequest) {
String authType = request.getParameter("authType");
logger.info("authType {} ",authType);
authRequest.setDetails(authenticationDetailsSource.buildDetails(request));
}
}
但这还不够，您需要扩展WebAuthenticationDetails。
原因是WebAuthenticationDetails 只提供remote IP address 和sessionId 所以，要添加authType，我们需要扩展这个类。
您必须扩展WebAuthenticationDetailsSource 以返回CustomAuthenticationDetails，如下所示。
CustomAuthenticationDetails.java
public class CustomAuthenticationDetails extends WebAuthenticationDetails{
private final String authType;
public CustomAuthenticationDetails(HttpServletRequest request) {
super(request);
authType = request.getParameter("authType");
}
public String getAuthType() {
return authType;
}
}
CustomWebAuthenticationDetailsSource.java
public class CustomWebAuthenticationDetailsSource extends WebAuthenticationDetailsSource {
@Override
public WebAuthenticationDetails buildDetails(HttpServletRequest context) {
return new CustomAuthenticationDetails(context);
}
}
请注意这些课程仅用于演示目的。
需要autowire这些类中的实际身份验证提供程序。

@Component
public class AuthenicationProviderJdbcLdapImpl implements AuthenticationProvider{
// you need to autowire jdbc auth provider

protected static class User{
private final String userId;

public User(String userId,String password) {
this.userId = userId;
this.password = password;
}

return userId;
}
public String getPassword() {
return password;
}
@Override
public String toString() {
return "User [userId=" + userId + ", password=" + password + "]";
}
}

private static final List<User> users1 = Arrays.asList(new User("admin1", "password"),new User("admin2", "password"));
private static final List<User> users2 = Arrays.asList(new User("admin3", "password"),new User("admin4", "password"));
@Override
public Authentication authenticate(Authentication authentication) throws AuthenticationException {
CustomAuthenticationDetails details = (CustomAuthenticationDetails) authentication.getDetails();
String authType = details.getAuthType();
logger.info("authType {}",authType);
if("jdbc".equalsIgnoreCase(authType)) {
logger.info("perfrom jdbc authentication");
//perform your authentication using jdbc
//the below is just for explaination
return performAuthentication(authentication, users1);
}else if("ldap".equalsIgnoreCase(authType)) {
logger.info("perfrom ldap authentication");
//perform your authentication using ldap
//the below is just for explaination
return performAuthentication(authentication, users2);
}
return null;
}
private Authentication performAuthentication(Authentication authentication,List<User> users) {
String credential = (String) authentication.getCredentials();
String userId = authentication.getName();
for(User user: users) {
if(user.getUserId().equals(userId)&& user.getPassword().equals(credential)) {
authentication = new UsernamePasswordAuthenticationToken(authentication.getPrincipal(), authentication.getCredentials(),authentication.getAuthorities());
return authentication;
}
}
return null;
}
@Override
public boolean supports(Class<?> authentication) {
return authentication.equals(UsernamePasswordAuthenticationToken.class);
}
}
如果您需要重定向不同的登录页面（不确定，如果您有要求），您可以在安全配置中注册 AuthenticationFailureHandler。这里根据条件重定向到 login 和 login1。
http.failureHandler(new AuthenticationFailureHandler() {
@Override
public void onAuthenticationFailure(HttpServletRequest request, HttpServletResponse response,
AuthenticationException exception) throws IOException, ServletException {
String whichPage = request.getParameter("whichPage");
System.out.println("inside login failure handler "+whichPage);
if("login1".equals(whichPage)) {
response.sendRedirect(request.getContextPath() +"/login1");
}else {
response.sendRedirect(request.getContextPath() +"/login");
}
}
})
