使用注释和java配置我不太清楚如何为spring security注册一个重写的过滤器.
我想要实现的是在不显示登录表单的情况下进行自动登录,因为此时用户已经过身份验证.因此,只会读取标题参数并使用spring security进行授权.
这是我正在尝试的简化版本,Spring安全性正常工作,除了有时显示登录屏幕.
引导BypassLoginFilter是我需要的全部内容.另外在某处读取http自动配置应该关闭这种行为,但不知道如何在纯java配置中实现.

BypassLoginFilter.java

import java.util.List;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class BypassLoginFilter extends AbstractAuthenticationProcessingFilter{
private static String HEADER_IS_ADMIN = "isAdmin";
public BypassLoginFilter()
{
super("/*");
}
//Never gets executed
@Override
public Authentication attemptAuthentication(HttpServletRequest request,HttpServletResponse response) throws AuthenticationException,IOException,ServletException {
boolean isAdmin = Boolean.valueOf(request.getHeader(HEADER_IS_ADMIN));
PreAuthenticatedAuthenticationToken authRequest = new PreAuthenticatedAuthenticationToken("","",getAuthorities(isAdmin));
authRequest.setDetails(authenticationDetailsSource.buildDetails(request));
return getAuthenticationManager().authenticate(authRequest);

您可以尝试以下方法.假设您有一个类似于以下内容的YourUser类：
public class YourUser extends org.springframework.security.core.userdetails.User{
...
public String getStartPage(){ return "/userhomepage"; }
...
}
然后你需要声明身份验证处理程序：
@Component
public class YourAuthenticationSuccessHandler extends SavedRequestAwareAuthenticationSuccessHandler {
protected String determineTargetUrl(HttpServletRequest request,HttpServletResponse response) {
Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
if (authentication.getPrincipal() instanceof YourUser) {
final YourUser user = (YourUser) authentication.getPrincipal();
return user.getStartPage();
}else {
return "/defaultPageForNonAuthenticatedUsers";
}
}
}
并在安全配置中使用它：
@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
// rest calls are ommited
http.successHandler(successHandler());
}
@Bean
public AuthenticationSuccessHandler successHandler() throws Exception {
return new YourAuthenticationSuccessHandler();
}
}
