Spring Boot：如何指定PasswordEncoder？

阮俊弼
2023-03-14
问题内容：

目前我上了主要课程：

package com.recweb.springboot;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;


@SpringBootApplication
/*@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})*/
public class SpringbootApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringbootApplication.class, args);
    }
}

一个成员类（id，名字..），一个MemberController类：

package com.recweb.springboot;

import java.util.Arrays;
import java.util.List;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class MemberController {
    @GetMapping("/members")
    public List<Member> getAllUsers() {
        return Arrays.asList(new Member(1, "amit"));
    }
}

和一个WebSecurityConfig类：

package com.recweb.springboot;

import org.springframework.context.annotation.Bean;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.core.userdetails.User;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.provisioning.InMemoryUserDetailsManager;

@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Bean
    public UserDetailsService userDetailsService() {
        InMemoryUserDetailsManager manager = new InMemoryUserDetailsManager();
        manager.createUser(User.withUsername("user").password("user").roles("USER").build());
        return manager;
    }
}

当我运行“ http：// localhost：8080 / members ”时，我得到一个登录页面，我输入“ user”作为用户＆“ user”作为密码，然后得到硬编码的Member。它工作正常，但随后我右键单击了我的项目-按运行方式作为Maven安装（因为我添加了一个依赖项，所以我也不知道是否有必要，也是第一次使用Maven）。从那时起，当我在登录页面上输入“用户”和“用户”时，出现此错误：

什么地方出了错？谢谢


问题答案：

在中spring-security-core:5.0.0.RC1，默认设置PasswordEncoder为DelegatingPasswordEncoder。当你将用户存储在内存中时，你将以纯文本形式提供密码，并且尝试从中检索编码器DelegatingPasswordEncoder以验证密码时，找不到与这些密码的存储方式匹配的密码。

而是使用这种方式来创建用户。

User.withDefaultPasswordEncoder().username("user").password("user").roles("USER").build();

你也可以简单{noop}地在密码前面加上前缀，以便DelegatingPasswordEncoder使用NoOpPasswordEncoder来验证这些密码。请注意，NoOpPasswordEncoder尽管已弃用，因为以纯文本存储密码不是一个好习惯。

User.withUsername("user").password("{noop}user").roles("USER").build();
