SpringSecurity解决WebSecurityConfigurerAdapter过时问题

旧版通过继承WebSecurityConfiurerAdapter，但是新版本中该类已经被标注为@Deprecated

旧版代码

package com.lzx.config;

import com.lzx.filter.JwtAuthenticationTokenFilter;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.config.http.SessionCreationPolicy;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter;

/**
 * @ClassName SecurityConfig
 * @Description TODO
 * @Author LiZhixiang
 * @Date 2023/10/3 17:32
 * @Version 1.0
 */
//@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }

    @Autowired
    private JwtAuthenticationTokenFilter jwtAuthenticationTokenFilter;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                //关闭csrf
                .csrf().disable()
                //不通过Session获取SecurityContext
                .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS)
                .and()
                .authorizeRequests()
                //对于登录接口 允许匿名访问
                .antMatchers("/user/login").anonymous()
                //除上面外的所有请求全部需要鉴权认证
                .anyRequest().authenticated();

        //把token校验过滤器添加到过滤器链中
        http.addFilterBefore(jwtAuthenticationTokenFilter, UsernamePasswordAuthenticationFilter.class);
    }

    @Bean
    @Override
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }

}

配置HttpSecurity

通过创建一个SecurityFilterChain bean来配置HttpSecurity

@Configuration
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .authorizeHttpRequests((authz) -> authz
                .anyRequest().authenticated()
            )
            .httpBasic(withDefaults());
    }
}

新版中通过构建一个SecurityFilterChain bean来做这件事：

@Configuration
public class SecurityConfiguration {

    @Bean
    public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
        http
            .authorizeHttpRequests((authz) -> authz
                .anyRequest().authenticated()
            )
            .httpBasic(withDefaults());
        return http.build();
    }
}

配置WebSecurity

下面是使用WebSecurityConfigurerAdapter忽略匹配/ignore1或/ignore2的请求的实例配置

@Configuration
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
    @Override
    public void configure(WebSecurity web) {
        web.ignoring().antMatchers("/ignore1", "/ignore2");
    }
}

新版建议注册一个WebSecurityCustomizer bean来做这件事：

@Configuration
public class SecurityConfiguration {
    @Bean
    public WebSecurityCustomizer webSecurityCustomizer() {
        return (web) -> web.ignoring().antMatchers("/ignore1", "/ignore2");
    }
}

配置AuthenticationManager

旧版通过重写authenticationManagerBean调用父类方法实现AuthenticationManager的注入

@Bean
    @Override
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }

新版建议这样注入：

    @Bean
    public AuthenticationManager authenticationManager(
            AuthenticationConfiguration authenticationConfiguration
    ) throws Exception {
        return authenticationConfiguration.getAuthenticationManager();
    }
