如何将折衷的WebsecurityConfigurerAdapter转换为SecurityFilterChain？

Question

我正在从事一个项目，我的问题是WebsecurityConfigurerAdapter。它行不通。它说的是“将弃用的类型WebsecurityConfigurerAdapter”如何将折衷的WebsecurityConfigurerAdapter转换为SecurityFilterChain？你能帮我吗？我不知道

在这里该怎么办是我的WebScurityConfig课程：

package com.projectuas.controller;
import com.projectuas.service.UserDetailsServiceImpl;

import org.springframework.context.annotation.*;
import org.springframework.security.authentication.dao.*;
import org.springframework.security.config.annotation.authentication.builders.*;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.*;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
 
@Configuration
@EnableWebSecurity
public class WebSecurityConfig  extends WebSecurityConfigurerAdapter {
 
    @Bean
    public UserDetailsService userDetailsService() {
        return new UserDetailsServiceImpl();
    }
     
    @Bean
    public BCryptPasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }
     
    @Bean
    public DaoAuthenticationProvider authenticationProvider() {
        DaoAuthenticationProvider authProvider = new DaoAuthenticationProvider();
        authProvider.setUserDetailsService(userDetailsService());
        authProvider.setPasswordEncoder(passwordEncoder());
         
        return authProvider;
    }


@Overide
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
    auth.authenticationProvider(authenticationProvider());
}

@Overide
protected void configure(HttpSecurity http) throws Exception {
    http.authorizeRequests()
        .antMatchers("/").hasAnyAuthority("USER", "ADMIN")
        .antMatchers("/new").hasAnyAuthority("ADMIN")
        .antMatchers("/edit/**").hasAnyAuthority("ADMIN")
        .antMatchers("/delete/**").hasAuthority("ADMIN")
        .anyRequest().authenticated()
        .and()
        .formLogin().permitAll()
        .and()
        .logout().permitAll()
        .and()
        .exceptionHandling().accessDeniedPage("/403")
        ;
}
}

使用WebScurityConfigurerAdapter时，我们需要覆盖以下方法。

@Override
protected void configure(HttpSecurity http) throws Exception {
    // http security configuration         
}

@Override
public void configure(WebSecurity web) throws Exception {         
    // web security configuration         
}  

如果我们想在不使用WebSecurityConfigurerAdapter的情况下执行此操作，则应通过注册这些豆子来代替它们。

@Bean
public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
 
}
 
@Bean
public WebSecurityCustomizer webSecurityCustomizer() {
     
}

示例

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class WebSecurityConfig {

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

@Bean
public PasswordEncoder passwordEncoder() {
    return new BCryptPasswordEncoder();
}

@Bean
public AuthenticationManager authManager(HttpSecurity http, PasswordEncoder passwordEncoder, UserDetailsService userDetailService)
        throws Exception {
    return http.getSharedObject(AuthenticationManagerBuilder.class)
            .userDetailsService(userDetailService)
            .passwordEncoder(passwordEncoder)
            .and()
            .build();
}

@Bean
public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
    http.authorizeRequests()
            .antMatchers("/").hasAnyAuthority("USER", "ADMIN")
            .antMatchers("/new").hasAnyAuthority("ADMIN")
            .antMatchers("/edit/**").hasAnyAuthority("ADMIN")
            .antMatchers("/delete/**").hasAuthority("ADMIN")
            .anyRequest().authenticated()
            .and()
            .formLogin().permitAll()
            .and()
            .logout().permitAll()
            .and()
            .exceptionHandling().accessDeniedPage("/403")
    ;

    return http.build();
}

@Bean
public WebSecurityCustomizer webSecurityCustomizer() {
    return (web) -> web.ignoring().antMatchers("/images/**", "/js/**", "/webjars/**");
}

}
