认证失败处理器与注销成功处理器

认证失败处理器

package com.example.springsecurity.handler;

import org.springframework.security.core.AuthenticationException;
import org.springframework.security.web.authentication.AuthenticationFailureHandler;
import org.springframework.stereotype.Component;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

@Component
public class SGFailureHandler implements AuthenticationFailureHandler {
    @Override
    public void onAuthenticationFailure(HttpServletRequest request, HttpServletResponse response, AuthenticationException exception) throws IOException, ServletException {
        System.out.println("认证失败了");
    }
}

package com.example.springsecurity.Config;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.web.authentication.AuthenticationFailureHandler;
import org.springframework.security.web.authentication.AuthenticationSuccessHandler;

@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private AuthenticationSuccessHandler successHandler;

    @Autowired
    private AuthenticationFailureHandler failureHandler;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.formLogin()
//                配置认证成功处理器
                .successHandler(successHandler)
//                配置认证失败处理器
                .failureHandler(failureHandler);

        http.authorizeRequests().anyRequest().authenticated();
    }
}

注销成功处理器

package com.example.springsecurity.handler;

import org.springframework.security.core.Authentication;
import org.springframework.security.web.authentication.logout.LogoutSuccessHandler;
import org.springframework.stereotype.Component;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

@Component
public class SGLogoutSuccessHandler implements LogoutSuccessHandler {
    @Override
    public void onLogoutSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws IOException, ServletException {
        System.out.println("注销成功");
    }
}

package com.example.springsecurity.Config;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.web.authentication.AuthenticationFailureHandler;
import org.springframework.security.web.authentication.AuthenticationSuccessHandler;
import org.springframework.security.web.authentication.logout.LogoutSuccessHandler;

@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private AuthenticationSuccessHandler successHandler;

    @Autowired
    private AuthenticationFailureHandler failureHandler;

    @Autowired
    private LogoutSuccessHandler logoutSuccessHandler;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.formLogin()
//                配置认证成功处理器
                .successHandler(successHandler)
//                配置认证失败处理器
                .failureHandler(failureHandler);

        http.logout()
                //配置注销成功处理器
                .logoutSuccessHandler(logoutSuccessHandler);

        http.authorizeRequests().anyRequest().authenticated();
    }
}
