Spring Security中successHandler和failureHandler使用方式

 更新時(shí)間：2024年08月01日 15:13:47   作者：放肆熱愛(ài)  
這篇文章主要介紹了Spring Security中successHandler和failureHandler使用方式,具有很好的參考價(jià)值,希望對(duì)大家有所幫助,如有錯(cuò)誤或未考慮完全的地方,望不吝賜教

前言

successHandler和failureHandler是Spring Security中兩個(gè)較為強(qiáng)大的用來(lái)處理登錄成功和失敗的回調(diào)函數(shù)，通過(guò)它們兩個(gè)我們就可以自定義一些前后端數(shù)據(jù)的交互。

successHandler

該方法有三個(gè)參數(shù)

  • req：相當(dāng)與HttpServletRequest
  • res：相當(dāng)與HttpServletRespose
  • authentication：這里保存了我們登錄后的用戶信息

進(jìn)行如下配置

.successHandler((req, resp, authentication) -> {
                    Object principal = authentication.getPrincipal();
                    resp.setContentType("application/json;charset=utf-8");
                    PrintWriter out = resp.getWriter();
                    out.write(new ObjectMapper().writeValueAsString(principal));
                    out.flush();
                    out.close();
                })

配置類(lèi)代碼

package com.scexample.sc.config;

import com.fasterxml.jackson.databind.ObjectMapper;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
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.WebSecurityConfigurerAdapter;
import org.springframework.security.crypto.password.NoOpPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.security.web.util.matcher.AntPathRequestMatcher;

import java.io.PrintWriter;

@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {


    @Bean
    PasswordEncoder passwordEncoder(){
        return NoOpPasswordEncoder.getInstance();
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication()
                .withUser("xiaoming")
                .password("123456").roles("admin");

    }

    @Override
    public void configure(WebSecurity web) throws Exception {
        web.ignoring().antMatchers("/js/**","/css/**","/images/**");  //這個(gè)是用來(lái)忽略一些url地址，對(duì)其不進(jìn)行校驗(yàn)，通常用在一些靜態(tài)文件中。
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
                .anyRequest().authenticated()
                .and()
                .formLogin()
                .loginPage("/aaa.html")
                 .loginProcessingUrl("/logintest")
                .usernameParameter("name")
                .passwordParameter("passwd")
                .successHandler((req, res, authentication) -> {
                    Object principal = authentication.getPrincipal();
                    res.setContentType("application/json;charset=utf-8");
                    PrintWriter out = res.getWriter();
                    out.write(new ObjectMapper().writeValueAsString(principal));
                    out.flush();
                    out.close();
                })
                .permitAll()
                .and()
                .csrf().disable()
        );
    }
}

再次登錄后

failureHandler

該方法有三個(gè)參數(shù)

  • req：相當(dāng)與HttpServletRequest
  • res：相當(dāng)與HttpServletRespose
  • e：這里保存了我們登錄失敗的原因

異常種類(lèi)：

  • LockedException 賬戶鎖定
  • CredentialsExpiredException 密碼過(guò)期
  • AccountExpiredException 賬戶過(guò)期
  • DisabledException 賬戶被禁止
  • BadCredentialsException 用戶名或者密碼錯(cuò)誤
.failureHandler((req, res, e) -> {
                    res.setContentType("application/json;charset=utf-8");
                    PrintWriter out = res.getWriter();
                    out.write(e.getMessage());
                    out.flush();
                    out.close();
                })

                .and()
                .csrf().disable()          
    }
}

未認(rèn)證處理方法

spring security默認(rèn)情況下，如果認(rèn)證不成功，直接重定向到登錄頁(yè)面。

但是項(xiàng)目中，我們有的時(shí)候不需要這樣，我們需要在前端進(jìn)行判斷 ，然后再?zèng)Q定進(jìn)行其他的處理，那我們就可以用authenticationEntryPoint這個(gè)接口進(jìn)行自定義了，取消它的默認(rèn)重定向行為。

該方法有三個(gè)參數(shù)

  • req：相當(dāng)與HttpServletRequest
  • res：相當(dāng)與HttpServletRespose
  • authException：指的就是我們未認(rèn)證的exception
 				.csrf().disable()
                .exceptionHandling()
                .authenticationEntryPoint((req, res, authException) -> {
                    res.setContentType("application/json;charset=utf-8");
                    PrintWriter out = res.getWriter();
                    out.write("檢測(cè)到未登錄狀態(tài)，請(qǐng)先登錄");
                    out.flush();
                    out.close();
                }
