📖前言

1	复制代码心态好了，就没那么累了。心情好了，所见皆是明媚风景。

“一时解决不了的问题，那就利用这个契机，看清自己的局限性，对自己进行一场拨乱反正。”正如老话所说，一念放下，万般自在。如果你正被烦心事扰乱心神，不妨学会断舍离。断掉胡思乱想，社区垃圾情绪，离开负面能量。心态好了，就没那么累了。心情好了，所见皆是明媚风景。

1. 启动类添加

java复制代码@EnableFeignClients
//对外开启暴露获取token的API接口
@EnableResourceServer
@EnableDiscoveryClient

2. 创建一个授权的配置文件 `AuthorizationServerConfig.java`

根据官方指示我们需要创建一个配置类去实现 AuthorizationServerConfigurer 所以我们，创建一个类去继承它的实现类AuthorizationServerConfigurerAdapter，具体代码如下：

java复制代码package com.cyj.dream.auth.config;

import com.cyj.dream.auth.entity.SysUser;
import com.cyj.dream.auth.persistence.service.impl.CustomUserServiceImpl;

import org.springframework.security.oauth2.config.annotation.web.configurers.AuthorizationServerEndpointsConfigurer;
import org.springframework.security.oauth2.config.annotation.web.configurers.AuthorizationServerSecurityConfigurer;
import org.springframework.security.oauth2.provider.CompositeTokenGranter;
import org.springframework.security.oauth2.provider.TokenGranter;
import org.springframework.security.oauth2.provider.client.ClientCredentialsTokenGranter;
import org.springframework.security.oauth2.provider.client.JdbcClientDetailsService;
import org.springframework.security.oauth2.provider.code.AuthorizationCodeTokenGranter;
import org.springframework.security.oauth2.provider.implicit.ImplicitTokenGranter;
import org.springframework.security.oauth2.provider.password.ResourceOwnerPasswordTokenGranter;
import org.springframework.security.oauth2.provider.refresh.RefreshTokenGranter;
import org.springframework.security.oauth2.provider.token.DefaultTokenServices;
import org.springframework.security.oauth2.provider.token.TokenEnhancer;
import org.springframework.security.oauth2.provider.token.TokenEnhancerChain;
import org.springframework.security.oauth2.provider.token.TokenStore;
import org.springframework.security.oauth2.provider.token.store.redis.RedisTokenStore;

3. 由于授权服务器本身也是资源服务器，所以也创建一个资源配置，代码如下

java复制代码package com.cyj.dream.auth.config;

import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.oauth2.config.annotation.web.configuration.EnableResourceServer;
import org.springframework.security.oauth2.config.annotation.web.configuration.ResourceServerConfigurerAdapter;

/**
 * @Description: 资源配置器
 * @BelongsProject: DreamChardonnay
 * @BelongsPackage: com.cyj.dream.auth.config
 * @Author: ChenYongJia
 * @CreateTime: 2021-09-30
 * @Email: chen87647213@163.com
 * @Version: 1.0
 */
@Configuration
// 启用资源服务
@EnableResourceServer
public class ResourceServerConfig extends ResourceServerConfigurerAdapter {

    /**
     * 配置资源接口安全，http.authorizeRequests()针对的所有url，但是由于登录页面url包含在其中，这里配置会进行token校验，校验不通过返回错误json，
     * 而授权码模式获取code时需要重定向登录页面，重定向过程并不能携带token，所有不能用http.authorizeRequests()，
     * 而是用requestMatchers().antMatchers("")，这里配置的是需要资源接口拦截的url数组
     *
     * @param http
     * @return void
     */
    @Override
    public void configure(HttpSecurity http) throws Exception {
        http    //配置需要保护的资源接口
                .requestMatchers().
                antMatchers("/user", "/test/need_token", "/logout", "/remove", "/update", "/test/need_admin", "/test/scope")
                .and().authorizeRequests().anyRequest().authenticated();
    }

}

4. 创建 `webSecurity` 配置

tex复制代码/*
     * OK ，关于这个配置我要多说两句：
     *
     * 1.首先当我们要自定义Spring Security的时候我们需要继承自WebSecurityConfigurerAdapter来完成，相关配置重写对应
     * 方法即可。 2.我们在这里注册CustomUserService的Bean，然后通过重写configure方法添加我们自定义的认证方式。
     * 3.在configure(HttpSecurity http)方法中，我们设置了登录页面，而且登录页面任何人都可以访问，然后设置了登录失败地址，也设置了注销请求，
     * 注销请求也是任何人都可以访问的。
     * 4.permitAll表示该请求任何人都可以访问，.anyRequest().authenticated(),表示其他的请求都必须要有权限认证。
     * 5.这里我们可以通过匹配器来匹配路径，比如antMatchers方法，假设我要管理员才可以访问admin文件夹下的内容，我可以这样来写：.
     * antMatchers("/admin/**").hasRole("ROLE_ADMIN")，也可以设置admin文件夹下的文件可以有多个角色来访问，
     * 写法如下：.antMatchers("/admin/**").hasAnyRole("ROLE_ADMIN","ROLE_USER")
     * 6.可以通过hasIpAddress来指定某一个ip可以访问该资源,假设只允许访问ip为210.210.210.210的请求获取admin下的资源，
     * 写法如下.antMatchers("/admin/**").hasIpAddress("210.210.210.210")
     * 7.更多的权限控制方式参看源码：
     */

                .cors()
                .and()
                // 取消跨站请求伪造防护
                .csrf().disable();
                /*.cors().and()
                .addFilterAt(ignoreLogoutFilter, LogoutFilter.class);*/
        // 为了可以使用 iframe 内嵌页面加载
        http.headers().frameOptions().sameOrigin();
        // 基于Token不需要session
        http.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);
        // 禁用缓存
        http.headers().cacheControl();
    }

    @Override
    public void configure(WebSecurity web) throws Exception {
        // 设置忽略资源
        web.ignoring().antMatchers(
                "/error",
                "/v2/api-docs/**",
                "/favicon.ico",
                "/css/**",
                "/js/**",
                "/images/*",
                "/fonts/**",
                "/**/*.png",
                "/**/*.jpg")
                // 不拦截 swagger2 所进行的配置
                .antMatchers("/templates/**")
                .antMatchers("/static/**")
                .antMatchers("/webjars/**")
                .antMatchers("/swagger-ui.html/**")
                .antMatchers("/v2/**")
                .antMatchers("/doc.html")
                .antMatchers("/api-docs-ext/**")
                .antMatchers("/swagger-resources/**");
        ;
    }

}

5. 创建一个 `controller` 进行访问测试

java复制代码package com.cyj.dream.auth.controller;

import com.baomidou.mybatisplus.core.conditions.query.LambdaQueryWrapper;
import com.cyj.dream.auth.entity.SysUser;
import com.cyj.dream.auth.persistence.service.ITbSysUserService;
import com.cyj.dream.core.aspect.annotation.ResponseResult;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiImplicitParam;
import io.swagger.annotations.ApiImplicitParams;
import io.swagger.annotations.ApiOperation;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

import java.security.Principal;

/**

 */
@Slf4j
@ResponseResult
@RestController
@RequestMapping(value = "/authUser", name = "用户控制器")
@Api(value = "authUser", tags = "用户控制器")
public class UserController {

    @Autowired
    private ITbSysUserService iTbSysUserService;

    @ApiOperation("通过名称获取用户信息")
    @ApiImplicitParams({
            @ApiImplicitParam(name = "userName", value = "用户名称", dataType = "String", required = true)
    })
    @RequestMapping(value = "getByName", method = RequestMethod.GET, name = "通过名称获取用户信息")
    public SysUser getByName(@RequestParam(value = "userName") String userName){
        LambdaQueryWrapper<SysUser> wrapper = new LambdaQueryWrapper<>();
        wrapper.eq(SysUser::getUsername, userName);
        return iTbSysUserService.getOne(wrapper);
    }

    @ApiOperation("获取授权的用户信息")
    @ApiImplicitParams({
            @ApiImplicitParam(name = "principal", value = "当前用户", dataType = "Principal", required = true)
    })
    @RequestMapping(value = "current", method = RequestMethod.GET, name = "获取授权的用户信息")
    public Principal user(Principal principal){
        // 授权信息
        return principal;
    }

}

带 token 的请求

不带 token 的请求

带 token，但是没有ROLE_ADMIN权限

6. 最后关于`Fegin` 调用服务 `Token` 丢失的问题

在微服务中我们经常会使用RestTemplate或Fegin来进行服务之间的调用，在这里就会出现一个问题，我们去调用别的服务的时候就会出现token丢失的情况，导致我们没有权限去访问。

所以我们需要加上一些拦截器将我们的 token 带走，针对fegin的配置代码如下：

java复制代码public class FeignRequestInterceptor implements RequestInterceptor {
    @Override
    public void apply(RequestTemplate requestTemplate) {
        ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
        assert attributes != null;
        HttpServletRequest request = attributes.getRequest();    
    // 设置请求头
    Enumeration<String> headerNames = request.getHeaderNames();
    if (headerNames != null) {
        while (headerNames.hasMoreElements()) {
            String name = headerNames.nextElement();
            String value = request.getHeader(name);
            requestTemplate.header(name, value);
        }
    }

    // 设置请求体，这里主要是为了传递 access_token
    Enumeration<String> parameterNames = request.getParameterNames();
    StringBuilder body = new StringBuilder();
    if (parameterNames != null) {
        while (parameterNames.hasMoreElements()) {
            String name = parameterNames.nextElement();
            String value = request.getParameter(name);

            // 将 Token 加入请求头
            if ("access_token".equals(name)) {
                requestTemplate.header("authorization", "Bearer " + value);
            }

            // 其它参数加入请求体
            else {
                body.append(name).append("=").append(value).append("&");
            }
        }
    }

    // 设置请求体
    if (body.length() > 0) {
        // 去掉最后一位 & 符号
        body.deleteCharAt(body.length() - 1);
        requestTemplate.body(body.toString());
    }
}
}

然后将这个拦截器加入到我们 fegin 请求拦截器中：

java复制代码@Configuration
public class FeignRequestConfiguration {
	@Bean
	public RequestInterceptor requestInterceptor() {
    	return new FeignRequestInterceptor();
	}
}

7. `Spring Security` 和 `Shiro`

相同点：

1：认证功能

2：授权功能

3：加密功能

4：会话管理

5：缓存支持

6：rememberMe功能…….

不同点：

优点：

1：Spring Security基于Spring开发，项目中如果使用Spring作为基础，配合Spring Security做权限更加方便，而Shiro需要和Spring进行整合开发

2：Spring Security功能比Shiro更加丰富些，例如安全防护

3：Spring Security社区资源比Shiro丰富

缺点：

1：Shiro的配置和使用比较简单，Spring Security上手复杂

2：Shiro依赖性低，不需要任何框架和容器，可以独立运行，而Spring Security依赖于Spring容器

8. 数据库表

sql复制代码-- used in tests that use HSQL
create table oauth_client_details (
  client_id VARCHAR(256) PRIMARY KEY,
  resource_ids VARCHAR(256),
  client_secret VARCHAR(256),
  scope VARCHAR(256),
  authorized_grant_types VARCHAR(256),
  web_server_redirect_uri VARCHAR(256),
  authorities VARCHAR(256),
  access_token_validity INTEGER,
  refresh_token_validity INTEGER,
  additional_information VARCHAR(4096),
  autoapprove VARCHAR(256)
);

create table oauth_client_token (
  token_id VARCHAR(256),
  token LONGVARBINARY,
  authentication_id VARCHAR(256) PRIMARY KEY,
  user_name VARCHAR(256),
  client_id VARCHAR(256)
);

create table oauth_access_token (
  token_id VARCHAR(256),
  token LONGVARBINARY,
  authentication_id VARCHAR(256) PRIMARY KEY,
  user_name VARCHAR(256),
  client_id VARCHAR(256),
  authentication LONGVARBINARY,
  refresh_token VARCHAR(256)
);

create table oauth_refresh_token (
  token_id VARCHAR(256),
  token LONGVARBINARY,
  authentication LONGVARBINARY
);

create table oauth_code (
  code VARCHAR(256), authentication LONGVARBINARY
);

create table oauth_approvals (
	userId VARCHAR(256),
	clientId VARCHAR(256),
	scope VARCHAR(256),
	status VARCHAR(10),
	expiresAt TIMESTAMP,
	lastModifiedAt TIMESTAMP
);

-- customized oauth_client_details table
create table ClientDetails (
  appId VARCHAR(256) PRIMARY KEY,
  resourceIds VARCHAR(256),
  appSecret VARCHAR(256),
  scope VARCHAR(256),
  grantTypes VARCHAR(256),
  redirectUrl VARCHAR(256),
  authorities VARCHAR(256),
  access_token_validity INTEGER,
  refresh_token_validity INTEGER,
  additionalInformation VARCHAR(4096),
  autoApproveScopes VARCHAR(256)
);
