springBoot集成oAuth2，系列三（UserDetailsService篇）

前言：

经过SpringBoot 集成 OAuth2 系列二（password篇），简单使用内存方式实现springBoot集成oauth2 后，今天来升华一下，真实项目中如何使用UserDetailsService方式来使用oauth2

系列文章：

SpringBoot 集成 OAuth2 系列一（最简单配置篇）

SpringBoot 集成 OAuth2 系列二（password篇）

springBoot集成oAuth2，系列三（UserDetailsService篇）

springBoot集成oAuth2，系列四（前后端分离web页面中使用oauth2跨域问题篇）

springBoot集成oAuth2，系列五（下载等location.href 如何使用token）

springBoot集成oAuth2，系列六（如何获取refresh_token）

springBoot集成oAuth2，系列七（根据refresh_token获取access_token）

springBoot集成oAuth2，系列八（使用redis存储token的时候，报错： java.lang.NoSuchMethodError: org.springframework.data.redis.connection.RedisConnection.set）

效果参考SpringBoot 集成 OAuth2 系列二（password篇）

在上一篇基础上改了如下代码

1.WebSecurityConfig

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.security.authentication.AuthenticationManager;
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.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;

@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    MyCustomUserDetailsService userDetailsService;

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

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


    @Bean
    @Override
    protected UserDetailsService userDetailsService() {
        return userDetailsService;
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(userDetailsService);
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        //所有请求必须认证
        http.authorizeRequests().anyRequest().authenticated();
    }
}

2.MyCustomUserDetailsService

import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.User;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.stereotype.Service;

import java.util.ArrayList;
import java.util.List;

@Service
public class MyCustomUserDetailsService implements UserDetailsService {
    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        List<GrantedAuthority> authorities = new ArrayList<GrantedAuthority>();
        authorities.add(new SimpleGrantedAuthority("ROLE_SIMPLE_PROTECTED"));
        UserDetails userDetails = new User("mayanze","$2a$10$Ih5mveMHG.N.P4kK3VmKEe2f8CBRB6kcEbGp8TGzDRYucs5ck39tu",authorities);
        return userDetails;
    }
}

AuthorizationServerConfig

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.security.oauth2.config.annotation.configurers.ClientDetailsServiceConfigurer;
import org.springframework.security.oauth2.config.annotation.web.configuration.AuthorizationServerConfigurerAdapter;
import org.springframework.security.oauth2.config.annotation.web.configurers.AuthorizationServerEndpointsConfigurer;

@Configuration
public class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {

    @Autowired
    private AuthenticationManager authenticationManager;//密码模式需要注入认证管理器
    @Autowired
    public PasswordEncoder passwordEncoder;
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients
                .inMemory()
                .withClient("first-client")
                .secret(passwordEncoder.encode("noonewilleverguess"))
                .scopes("resource:read")
                .authorizedGrantTypes("password","authorization_code");
    }

    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) {
        endpoints.authenticationManager(authenticationManager);
    }
}
