无法解析符号“WebSecurityConfigurerAdapter” - 方法不会覆盖其超类中的方法

Question

我在 Spring Security 配置中遇到问题，编译器无法解析符号“WebSecurityConfigurerAdapter”。此外，我遇到错误，指出方法不会覆盖其超类中的方法。相关代码片段如下：

package com.shubham.dev.discoveryserver.config;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.Customizer;
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.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.crypto.password.NoOpPasswordEncoder;

@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Value("${app.eureka.username}")
    private String username;
    @Value("${app.eureka.password}")
    private String password;

    @Override
    public void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication()
                .passwordEncoder(NoOpPasswordEncoder.getInstance())
                .withUser(username).password(password)
                .authorities("USER");
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf(csrf->csrf.disable())
                .authorizeRequests().anyRequest()
                .authenticated()
                .and()
                .httpBasic(Customizer.withDefaults());
    }
}

    </dependencies>

</project>

SpringBoot版本：3.2.1

错误：

Cannot resolve symbol 'WebSecurityConfigurerAdapter':8 
Cannot resolve symbol 'WebSecurityConfigurerAdapter':12  
Method does not override method from its superclass:19 
Method does not override method from its superclass:27

Answer 1

我猜您正在使用的

spring-boot

版本是

3.x

并且从这个版本开始

WebSecurityConfigurerAdapter

已被删除，您必须按照下一篇文章来替换已弃用/删除的内容 没有 websecurity 配置适配器的 spring-security

还有配置文档的一部分，将帮助您摆脱旧的配置。

stackOverflow 上有很多关于这种迁移的相关主题。首先，您可以检查我对此问题的相关答案更新到最新的spring-security-replacing-deprecated-methods
