添加启动类

/**

 * @date： 2021/11/24
 * @description：
 * @modifiedBy：
 * @version: 1.0
 */
@SpringBootApplication
@EnableDiscoveryClient
public class AuthApp {
    public static void main(String[] args) {
        SpringApplication.run(AuthApp.class, args);
    }
}

spring security 基本组件介绍

ClientDetailsService

通过实现该service，用来添加获取客户端逻辑

UserDetails

通过实现该类，用来封装用户信息，也可以说是用来扩展用户信息的

UserDetailsService

通过实现该service，用来添加根据用户名 来获取用户信息的逻辑，可以从数据库获取，也可以从其他服务中获取用户信息

AuthorizationServerConfigurerAdapter

该类用来添加一些授权服务配置，如配置客户端ClientDetailsService

WebSecurityConfigurerAdapter

该类用来配置HttpSecurity
相关信息，如对那些资源需要拦截认证，对哪些资源进行放行等

DaoAuthenticationProvider

默认的用户名和密码授权认证提供者

主要配置介绍

创建用户封装类

package com.ams.auth.security.details.user;

import lombok.AllArgsConstructor;
import lombok.Builder;
import lombok.Data;
import lombok.NoArgsConstructor;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;

import java.util.Collection;

/**

 * @description：
 * @modifiedBy：
 * @version: 1.0
 */
/**
 * 系统管理用户认证信息
 *
 * @author <a href="mailto:xianrui0365@163.com">haoxianrui</a>
 * @date 2021/9/27
 */
@Data
@Builder
@AllArgsConstructor
@NoArgsConstructor
public class SysUserDetails implements UserDetails {

    /**
     * 扩展字段
     */
    private Long userId;

    /**
     * 默认字段
     */
    private String username;
    private String password;
    private Boolean enabled;
    private Collection<SimpleGrantedAuthority> authorities;


    @Override
    public Collection<? extends GrantedAuthority> getAuthorities() {
        return this.authorities;
    }

    @Override
    public String getPassword() {
        return this.password;
    }

    @Override
    public String getUsername() {
        return this.username;
    }

    @Override
    public boolean isAccountNonExpired() {
        return true;
    }

    @Override
    public boolean isAccountNonLocked() {
        return true;
    }

    @Override
    public boolean isCredentialsNonExpired() {
        return true;
    }

    @Override
    public boolean isEnabled() {
        return this.enabled;
    }
}

创建根据用户名获取封装的用户信息的service

目前只是写死的用户信息，后面会通过feign从管理端服务获取用户信息，暂时只是为了服务能跑通

package com.ams.auth.security.details.user;

import com.ams.auth.comm.enums.PasswordEncoderTypeEnum;
import lombok.RequiredArgsConstructor;
import lombok.extern.slf4j.Slf4j;
import org.springframework.security.authentication.AccountExpiredException;
import org.springframework.security.authentication.DisabledException;
import org.springframework.security.authentication.LockedException;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.stereotype.Service;

import java.util.ArrayList;
import java.util.Collection;
/**
 * Created with IntelliJ IDEA.
 *
 * @author： AI码师
 * @date： 2021/11/24
 * @description：
 * @modifiedBy：
 * @version: 1.0
 */
@Service("sysUserDetailsService")
@Slf4j
@RequiredArgsConstructor
public class SysUserDetailsServiceImpl implements UserDetailsService {
    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        // 后面从管理端获取用户信息
        SysUserDetails userDetails = loadUser(username);
        if (!userDetails.isEnabled()) {
            throw new DisabledException("该账户已被禁用!");
        } else if (!userDetails.isAccountNonLocked()) {
            throw new LockedException("该账号已被锁定!");
        } else if (!userDetails.isAccountNonExpired()) {
            throw new AccountExpiredException("该账号已过期!");
        }
        return userDetails;
    }

    private SysUserDetails loadUser(String username) {
        Collection<SimpleGrantedAuthority> authorities =new ArrayList<>();
        authorities.add(new SimpleGrantedAuthority("admin"));
        return SysUserDetails.builder()
                .userId(1L)
                .username(username)
                .enabled(true)
                .authorities(authorities)
                .password(PasswordEncoderTypeEnum.BCRYPT.getPrefix() + new BCryptPasswordEncoder().encode("123456789")).build();
    }

}

创建客户端信息获取service

package com.ams.auth.security.details.client;

import com.ams.auth.comm.enums.PasswordEncoderTypeEnum;
import lombok.RequiredArgsConstructor;
import org.springframework.cache.annotation.Cacheable;
import org.springframework.security.oauth2.provider.ClientDetails;
import org.springframework.security.oauth2.provider.ClientDetailsService;
import org.springframework.security.oauth2.provider.client.BaseClientDetails;
import org.springframework.stereotype.Service;

/**
 * Created with IntelliJ IDEA.
 *
 * @author： AI码师
 * @date： 2021/11/24
 * @description：
 * @modifiedBy：
 * @version: 1.0
 */
@Service
@RequiredArgsConstructor
public class ClientDetailsServiceImpl implements ClientDetailsService {
    @Override
    @Cacheable(cacheNames = "auth", key = "'oauth-client:'+#clientId")
    public ClientDetails loadClientByClientId(String clientId) {
        // 后面通过feign从管理端获取，目前写死
        BaseClientDetails clientDetails = new BaseClientDetails(
                "ams",
                "",
                "all",
                "password,client_credentials,refresh_token,authorization_code",
                "",
                "http://www.baidu.com"

        );
        clientDetails.setClientSecret(PasswordEncoderTypeEnum.NOOP.getPrefix() + "ams");
        clientDetails.setAccessTokenValiditySeconds(3600);
        clientDetails.setRefreshTokenValiditySeconds(36000000);
        return clientDetails;
    }
}

创建安全配置

这里主要配置了如下内容:

• 设置哪些资源不被拦截
• 设置基本认证
• 添加默认的用户名和密码认证器提供者DaoAuthenticationProvider
• 设置用户名密码验证提供者中的用户获取来源sysUserDetailsService

package com.ams.auth.security.config;

import lombok.RequiredArgsConstructor;
import lombok.extern.slf4j.Slf4j;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.authentication.AuthenticationManager;

@RequiredArgsConstructor
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    private final UserDetailsService sysUserDetailsService;


    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .authorizeRequests().antMatchers("/oauth/**").permitAll()
                .anyRequest().authenticated()
                .and()
                .httpBasic()
                .and()
                .csrf().disable();
    }

    /**

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

    /**
     * 添加自定义认证器
     *
     * @param auth
     */
    @Override
    public void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.authenticationProvider(daoAuthenticationProvider());
    }

    /**
     * 设置默认的用户名密码认证授权提供者
     *
     * @return
     */
    @Bean
    public DaoAuthenticationProvider daoAuthenticationProvider() {
        DaoAuthenticationProvider provider = new DaoAuthenticationProvider();
        provider.setUserDetailsService(sysUserDetailsService);
        provider.setPasswordEncoder(passwordEncoder());
        provider.setHideUserNotFoundExceptions(false); // 是否隐藏用户不存在异常，默认:true-隐藏；false-抛出异常；
        return provider;
    }

    @Bean
    public PasswordEncoder passwordEncoder() {
        return PasswordEncoderFactories.createDelegatingPasswordEncoder();
    }


}

添加授权服务相关配置

这里配置了如下内容：

• 设置oauth客户端 获取信息来源 clientDetailsService
• 设置默认的token存储方式(后面改成redis存储)
• 添加token增强器(在token中添加用户信息)
• 添加token 加密方式

package com.ams.auth.security.config;

        KeyPair keyPair = factory.getKeyPair("jwt", "123456".toCharArray());
        return keyPair;
    }
}

生成jks 文件

使用java 命令行进行生成

keytool -genkey -alias jwt -keyalg RSA -keysize 1024 -keystore jwt.jks -validity 365

按照提示依次输入

拷贝jks到项目的resource目录中
​

创建获取token 入口

为了能够捕获在认证过程中出现的所有异常，这里通过复写security中的token入口，来实现此目的
内容其实少，就是手动去调用tokenPoint的方法触发

package com.ams.auth.security;

import cn.hutool.json.JSONUtil;
import com.ams.auth.comm.RequestUtils;
import com.ams.auth.comm.result.R;
import lombok.AllArgsConstructor;
import lombok.extern.slf4j.Slf4j;
import org.springframework.security.oauth2.common.OAuth2AccessToken;
import org.springframework.security.oauth2.provider.endpoint.TokenEndpoint;
import org.springframework.web.HttpRequestMethodNotSupportedException;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

import java.security.Principal;
import java.util.Map;
/**
 * Created with IntelliJ IDEA.
 *
 * @author： AI码师
 * @date： 2021/11/24
 * @description：
 * @modifiedBy：
 * @version: 1.0
 */
@RestController
@RequestMapping("/oauth")
@AllArgsConstructor
@Slf4j
public class AuthController {

    private final TokenEndpoint tokenEndpoint;

    @PostMapping("/token")
    public Object postAccessToken(
            Principal principal,
            @RequestParam Map<String, String> parameters
    ) throws HttpRequestMethodNotSupportedException {
        OAuth2AccessToken accessToken = tokenEndpoint.postAccessToken(principal, parameters).getBody();
        return R.ok(accessToken);
    }
}

添加异常统一处理类

package com.ams.auth.comm.exception;

import com.ams.auth.comm.result.R;
import com.ams.auth.comm.result.ResultCode;
import lombok.extern.slf4j.Slf4j;
import org.springframework.core.annotation.Order;

     */
    @ResponseStatus(HttpStatus.BAD_REQUEST)
    @ExceptionHandler(UsernameNotFoundException.class)
    public R handleUsernameNotFoundException(UsernameNotFoundException e) {
        return R.failed(ResultCode.USER_NOT_EXIST);
    }

    /**

    @ExceptionHandler(InvalidClientException.class)
    public R handleInvalidGrantException(InvalidClientException e) {
        return R.failed(ResultCode.CLIENT_AUTHENTICATION_FAILED);
    }

    @ResponseStatus(HttpStatus.BAD_REQUEST)
    @ExceptionHandler({InternalAuthenticationServiceException.class})
    public R handleInternalAuthenticationServiceException(InternalAuthenticationServiceException e) {
        return R.failed(e.getMessage());
    }

    /**
     * token 无效或已过期
     *
     * @param e
     * @return
     */
    @ResponseStatus(HttpStatus.BAD_REQUEST)
    @ExceptionHandler({InvalidTokenException.class})
    public R handleInvalidTokenExceptionException(InvalidTokenException e) {
        return R.failed(e.getMessage());
    }

}

添加bootsrap.yml

在ams-auth->resources 下创建bootstrap.yml文件，并配置nacos客户端信息
cloud.lebao.site:8848 -> 换成你自己的nacos地址

server:
  port: 20001
spring:
  application:
    name: ams-auth
  cloud:
    nacos:
      # 注册中心
      discovery:
        server-addr: http://cloud.lebao.site:8848
      # 配置中心
      config:
        server-addr: ${spring.cloud.nacos.discovery.server-addr}
        file-extension: yaml
        shared-configs[0]:
          data-id: ams-common.yaml
          refresh: true
logging:
  level:
    spring.: DEBUG

在nacos中添加配置

• ams-auth.yaml

TEST: 111 # 随便配置的，后面需要按需配置

• ams-common.yaml

redis:
  host: cloud.lebao.site
  port: 6379
  password: root
mysql:
  host: cloud.lebao.site
  port: 3306
  username: root
  password: root


测试获取token

用户名和密码获取

• 接口地址：http://localhost:20001/oauth/token
• 请求方式：POST
• 请求参数

• header配置：Content-Type = application/json
• 客户端信息

• 请求结果

刷新token

• 接口地址：http://localhost:20001/oauth/token
• 请求方式：POST
• 请求参数

• 客户端信息配置

• 请求结果

获取授权码

• 链接：http://localhost:20001/oauth/authorize?response_type=code&client_id=ams
• 用户名和密码登陆

• 拿到授权码：BfhrVd

根据授权码获取token

• 接口地址：http://localhost:20001/oauth/token
• 请求方式：POST
• 请求参数

• 返回token

总结

本篇文章介绍了如何集成SpringSecurity，介绍了SpringSecurity核心组件以及分别是用来做什么的，但是这里只是简单使用了他的获取token功能，下一期会整合网关实现一套完整的认证系统。
