java – 没有web.xml的Spring安全自定义身份验证过滤器

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.

SecurityWebApplicationInitializer.java

import org.springframework.security.web.context.AbstractSecurityWebApplicationInitializer;

public class SecurityWebApplicationInitializer extends AbstractSecurityWebApplicationInitializer{

}

SecurityConfig .java

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.builders.WebSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.web.authentication.logout.logoutFilter;

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(securedEnabled=true,prePostEnabled=true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    public void configure(WebSecurity web) throws Exception {
        web.ignoring().antMatchers("/resources/**");    
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().disable();
        http.authorizeRequests().antMatchers("/*").permitAll()
                .anyRequest().hasRole("USER").and()
                .formLogin()
                .permitAll();
        http.addFilterBefore(new BypassLoginFilter(),logoutFilter.class);
        //.and().anonymous().disable();
    }

    @Override
    @Autowired
    protected void registerauthentication(AuthenticationManagerBuilder auth) {
        try {
            auth.inMemoryAuthentication().withUser("user").password("password")
            .roles("USER").and().withUser("admin").password("password")
            .roles("USER","ADMIN");
        } catch (Exception e) {
            e.printstacktrace();
        }
    }
}

BypassLoginFilter.java

import java.io.IOException;
import java.util.ArrayList;
import java.util.List;

import javax.servlet.servletexception;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.security.core.Authentication;
import org.springframework.security.core.AuthenticationException;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.web.authentication.AbstractAuthenticationProcessingFilter;
import org.springframework.security.web.authentication.preauth.PreAuthenticatedAuthenticationToken;

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);
    }

    private List

最佳答案

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();
    }
}
