springSecurity+Oauth2.0之授权模式（客户端、密码模式）

SpringSecurity+Oauth2.0之授权模式

1: 客户端模式：

          客户端模式（Client Credentials Grant）指客户端以自己的名义，而不是以用户的名义，向"服务提供商"进行认证。严格地说，客户端模式并不属于OAuth框架所要解决的问题。在这种模式中，用户直接向客户端注册，客户端以自己的名义要求"服务提供商"提供服务，其实不存在授权问题。

maven依赖：

<dependency>
     <groupId>org.springframework.boot</groupId>
     <artifactId>spring-boot-starter-security</artifactId>
</dependency>
<dependency>
   <groupId>org.springframework.security.oauth.boot</groupId>
   <artifactId>spring-security-oauth2-autoconfigure</artifactId>
   <version>2.0.6.RELEASE</version>
</dependency>

创建Oauth2.0需要创建三个相关的表,直接使用官方的SQL脚本即可生成(不要修改表名和字段名)

OAuth2 官方的项目中可以找到：https://github.com/spring-projects/spring-security-oauth/blob/master/spring-security-oauth2/src/test/resources/schema.sql

配置认证服务器：

/**

 * @ClassName AuthorizationServerConfig
 * @Description 配置认证服务器 提供/oauth2/authorize,/oauth2/token,/oauth2/check_token,/oauth2/confirm_access,/oauth2/error
 * @EnableAuthorizationServer // 这个注解告诉 Spring 这个应用是 OAuth2 的授权服务器
 * @Date 2020/4/20 14:47
 * @Version 1.0
 */

@Configuration
@EnableAuthorizationServer
public class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {


    @Autowired
    private DataSource dataSource;


    @Bean
    public TokenStore tokenStore() {
        //使用内存中的 token store
//        return new InMemoryTokenStore();
        //使用Jdbctoken store
        return new JdbcTokenStore(dataSource);
    }

    @Bean
    public ClientDetailsService clientDetails() {
        return new JdbcClientDetailsService(dataSource);
    }

    /**

    @Bean
    @Primary
    public DefaultTokenServices defaultTokenServices() {
        DefaultTokenServices services = new DefaultTokenServices();
        //设置Token 20秒过期
        services.setAccessTokenValiditySeconds(20);
        //设置刷新token的过期时间
        services.setRefreshTokenValiditySeconds(666);
        services.setTokenStore(tokenStore());
        return services;
    }

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        // 配置客户端, 用于client认证
        clients.withClientDetails(clientDetails());
// 第一次使用的时候，需要配置客户端信息,或者手动添加客户端信息到数据库oauth_client_details表中
//        clients.jdbc(dataSource)
//                .withClient("myClient")
//                .secret(new BCryptPasswordEncoder().encode("123456"))

    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
//        endpoints.tokenStore(tokenStore())
        endpoints.tokenServices(defaultTokenServices())
                //接收GET和POST
                .allowedTokenEndpointRequestMethods(HttpMethod.GET, HttpMethod.POST);

    }

    @Override

                .checkTokenAccess("isAuthenticated()")
                .allowFormAuthenticationForClients();//允许表单登录
    }


}

 如果说是其他模式:

.authorizedGrantTypes("authorization_code","client_credentials","password","refresh_token")//授权方式

"authorization_code" : code模式
"client_credentials": 客户端模式
"password": 密码模式
"implicit": 简化模式

关于设置Token的过期时间如果配置的是从数据库读取，上面配置的Token过期时间将无效，可以在数据库中设置过期时间

配置资源服务器：

/**
 * @Author dw
 * @ClassName ResourceServerConfig
 * @Description 配置资源器
 * @EnableResourceServer 这个类表明了此应用是OAuth2 的资源服务器，此处主要指定了受资源服务器保护的资源链接
 * @Date 2020/4/20 15:03
 * @Version 1.0
 */
@Configuration
@EnableResourceServer
public class ResourceServerConfig extends ResourceServerConfigurerAdapter {

    @Override
    public void configure(HttpSecurity http) throws Exception {
        http.csrf().disable()
                //匹配需要资源认证路径
                .antMatcher("/**")
                .authorizeRequests()
                //匹配不需要资源认证路径
                .antMatchers("/oauth/**").permitAll()
                .anyRequest().authenticated();
    }

}

配置springSecurity:

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

// 配置密码的加密方式
    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }

    /**
     * 用来配置拦截保护的请求
     *
     * @param http
     * @throws Exception
     */
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().disable()
                //匹配需要资源认证路径
                .antMatcher("/**")
                .authorizeRequests()
                //匹配不需要资源认证路径
                .antMatchers("/oauth/**").permitAll()
                .anyRequest().authenticated();
    }

    public static void main(String[] args) {
        System.out.println(new BCryptPasswordEncoder().encode("123456"));
    }

}

Controller受保护的资源：

/**
 * @Author dw
 * @ClassName HelloSecurityController
 * @Description
 * @Date 2020/4/14 11:34
 * @Version 1.0
 */
@RestController
public class HelloSecurityController {

    @GetMapping("/admin/hello")
    public String admin() {
        return "hello admin";
    }

    @GetMapping("/user/hello")
    public String user() {
        return "hello user";
    }

    @GetMapping("/db/hello")
    public String db() {
        return "hello db";
    }

    @GetMapping("/hello")
    public String hello() {
        return "hello";
    }

}

注意：这里可能需要你手动配置你的客户端到这张表中

获取token：

(A) 客户端向认证服务器进行身份认证，并要求一个访问令牌。请求的参数如下：

• grant_type：表示授权类型，必选项，此处的值固定为"client_credentials"
• client_id：表示客户端的ID，必选项
• client_secret：客户端的密码，可选项
• scope：表示申请的权限范围，可选项

 通过Token访问受保护的资源：

 2: 密码模式：

这里分成资源服务器与授权服务器，即分离的形式来搭建，而不是资源服务器与授权服务器都在同一个项目中

maven依赖（两个项目中都要添加）：

#      当一个连接使用完归还到连接池时是否进行验证
      testOnReturn: false
#      启用游标缓存，这个对数据库的性能提升很大
      poolPreparedStatements: true
#        要启用PSCache，必须配置大于0，当大于0时，poolPreparedStatements自动触发修改为true。在Druid中，不会存在Oracle下PSCache占用内存过多的问题，可以把这个数值配置大一些，比如说100

      filter:
        stat:
          log-slow-sql: true
          slow-sql-millis: 2000

创建表：用户、角色、权限、用户角色表、角色权限表。

创建service

@Service
public class MyUserDetailServiceImpl implements UserDetailsService {
    @Autowired
    private UserMapperDao userMapperDao;
    @Autowired
    private PasswordEncoder passwordEncoder;

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        User user = userMapperDao.loadUserByUsername(username);
        String encodePassword = passwordEncoder.encode(user.getPassword());
        System.out.println("加密后的密码：" + encodePassword);
        user.setPassword(encodePassword);
        if (user == null) {
            throw new UsernameNotFoundException("账户不存在!");
        }
        List<Role> userRoles = userMapperDao.getUserRolesByUid(user.getId());
        user.setUserRoles(userRoles);
        return user;
    }
}

 */
@Configuration
@EnableResourceServer
public class ResourceServerConfig extends ResourceServerConfigurerAdapter {


    @Override
    public void configure(HttpSecurity http) throws Exception {
        http
                //定义哪些url需要被保护  哪些不需要保护
                .authorizeRequests()
                //定义这两个链接不需要登录可访问

                .and()
                .csrf().disable();//防止跨站请求  spring security中默认开启
    }

}

配置springSecurity

package com.dw.study.securityConfig;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;

import org.springframework.security.crypto.password.PasswordEncoder;

/**

@Configuration
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

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


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

    /**

//                .passwordEncoder(passwordEncoder());
//    }


    /**

     * @throws Exception
     */
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                //定义哪些url需要被保护  哪些不需要保护
             .authorizeRequests()
                //定义这两个链接不需要登录可访问
             .antMatchers("/oauth/token" , "oauth/check_token").permitAll()
                //定义所有的都不需要登录  目前是测试需要
//             .antMatchers("/**").permitAll()
             .anyRequest().authenticated() //其他的都需要登录
             //.antMatchers("/sys/**").hasRole("admin")///sys/**下的请求 需要有admin的角色
             .and()
             .formLogin()
//                .loginPage("/login") //如果未登录则跳转登录的页面   这儿可以控制登录成功和登录失败跳转的页面
             .and()
             .csrf().disable();//防止跨站请求  spring security中默认开启
    }

}

配置全局异常处理类：

package com.dw.study.webConfig;

import org.bouncycastle.asn1.ocsp.ResponseData;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.http.HttpHeaders;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.security.oauth2.common.exceptions.OAuth2Exception;
import org.springframework.security.oauth2.provider.error.DefaultWebResponseExceptionTranslator;
import org.springframework.security.oauth2.provider.error.WebResponseExceptionTranslator;
import org.springframework.stereotype.Component;

/**
 * @Author dw
 * @Description web全局异常返回处理器
 * @Date 2020/4/24 14:14
 * @Param
 * @return
 */
@Component
public class CustomWebResponseExceptionTranslator extends DefaultWebResponseExceptionTranslator {

    private static final Logger LOGGER = LoggerFactory.getLogger(CustomWebResponseExceptionTranslator.class);

    @SuppressWarnings("PMD")
    @Override

public ResponseEntity<OAuth2Exception> translate(Exception e) throws Exception {

    ResponseEntity responseEntity = super.translate(e);
    LOGGER.info("statusCode: " + responseEntity.getStatusCodeValue());
    OAuth2Exception oAuth2Exception = new OAuth2Exception("出错了！！");
    if(responseEntity.getStatusCodeValue() == 401){
        oAuth2Exception.addAdditionalInformation("code", "401");
        oAuth2Exception.addAdditionalInformation("data", "");
        oAuth2Exception.addAdditionalInformation("message", "用户名错误!");
        return new ResponseEntity(oAuth2Exception, HttpStatus.UNAUTHORIZED);
    }else if(responseEntity.getStatusCodeValue() == 400){
        oAuth2Exception.addAdditionalInformation("code", "400");
        oAuth2Exception.addAdditionalInformation("data", "");
        oAuth2Exception.addAdditionalInformation("message", "用户密码错误!");
        return new ResponseEntity(oAuth2Exception, HttpStatus.BAD_REQUEST);
    }else {
        oAuth2Exception.addAdditionalInformation("code", String.valueOf(responseEntity.getStatusCodeValue()));
        oAuth2Exception.addAdditionalInformation("data", "");
        oAuth2Exception.addAdditionalInformation("message", "认证异常");
        return new ResponseEntity(oAuth2Exception, HttpStatus.UNAUTHORIZED);
    }
}

 }

创建访问当前登录用户的接口：

package com.dw.study.controller;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

import java.security.Principal;

/**
 * @Author dw
 * @ClassName UserInfoController
 * @Description
 * @Date 2020/4/23 15:06
 * @Version 1.0
 */
@RestController
public class UserInfoController {


    @Value("${server.port}")
    private String serverPort;

    @GetMapping(value = "/userInfo")
    public Principal getUserInfo(Principal principal) {
        System.out.println("通过端口：" + serverPort + "获取用户信息：" + principal);
        return principal;
    }

}

好的到这里认证服务器就配置完了。

下面配置资源服务器：

1、pom同上；

 修改yml：

server:
  port: 8087

management:
  security:
    enabled: false

security:
  oauth2:
    #token检查的授权端url
    authorization:
      check-token-access: http://127.0.0.1:8086/oauth/check_token
    #对应的注册码与注册密码
    client:
      id: oauth2-password
      client-secret: 123456
      userAuthorizationUri: http://127.0.0.1:8086/oauth/authorize
      access-token-uri: http://127.0.0.1:8086/oauth/token
      scope: all
      grant-type: password
#      authentication-scheme: form
    #获得授权端的当前用户信息url
    resource:
      user-info-uri: http://127.0.0.1:8086/userInfo

定义资源服务器配置：

package com.dw.study.oauth2Config;

import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.oauth2.config.annotation.web.configuration.EnableOAuth2Client;
import org.springframework.security.oauth2.config.annotation.web.configuration.EnableResourceServer;
import org.springframework.security.oauth2.config.annotation.web.configuration.ResourceServerConfigurerAdapter;
import org.springframework.web.cors.CorsConfiguration;

import javax.servlet.http.HttpServletResponse;

/**
 * @Author dw
 * @ClassName ResourceServerConfig
 * @Description 配置资源器
 * @EnableResourceServer 这个类表明了此应用是OAuth2 的资源服务器，此处主要指定了受资源服务器保护的资源链接
 * @EnableGlobalMethodSecurity : 开启三种可以在方法上面加权限控制的注解
 * @Date 2020/4/20 15:03
 * @Version 1.0
 */
@Configuration
@EnableResourceServer
@EnableOAuth2Client
@EnableGlobalMethodSecurity(prePostEnabled = true, securedEnabled = true, jsr250Enabled = true)
public class ResourceServerConfig extends ResourceServerConfigurerAdapter {


    @Override
    public void configure(HttpSecurity http) throws Exception {
        http.csrf().disable()
                //匹配需要资源认证路径
                .antMatcher("/**")
                .authorizeRequests()
                //匹配不需要资源认证路径
                .antMatchers("/oauth/**").permitAll()
                .anyRequest().authenticated();
    }

}

定义获取用户信息的util：

package com.dw.study.Utils;

import org.springframework.security.core.Authentication;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.security.oauth2.provider.OAuth2Authentication;

import java.util.LinkedHashMap;

/**
 * @Author dw
 * @ClassName UserUtil
 * @Description
 * @Date 2020/4/24 17:05
 * @Version 1.0
 */
public class UserUtil {

    private UserUtil (){}

    public static LinkedHashMap getUser(){
        return getUserDetails();
    }

    private static LinkedHashMap getUserDetails() {
        Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
        OAuth2Authentication oAuth2Authentication = (OAuth2Authentication)authentication;
        LinkedHashMap userDetails = (LinkedHashMap) oAuth2Authentication.getUserAuthentication().getDetails();
        LinkedHashMap principal = (LinkedHashMap) userDetails.get("principal");
        // 这里需要手动传换成User对象
        return principal;
    }

}

最后新建user、role类，同上面一样

建controller

@RestController
@Slf4j
public class MyController {

    @Value("${server.port}")
    private String serverPort;

    @GetMapping("/get")
    public String get(){
        return "成功获取到资源： port: " + serverPort;
    }

    @GetMapping("/userInfo")
    public Object getUserInfo(){
        LinkedHashMap user = UserUtil.getUser();
        return user;
    }

}

好的，配置完成。下面测试

 1：oauth_client_detais这张表中配置我们的客户端信息

 启动两个项目，然后使用postman：

1: 获取token：

 2：刷新token获取token：

 访问用户信息：

关于使用HTTP请求头  Authorization，不直接用  client_id 和  client_secret

 客户端发送http请求流程：
服务器发现配置了http auth，于是检查request里面有没有"Authorization"的http header
如果有，则判断Authorization里面的内容是否在用户列表里面，Authorization header 的典型数据为"Authorization: Basic jdhaHY0="，

其中Basic   表示基础认证，

jdhaHY0=   是base64编码的"user:passwd"字符串。

如果没有，或者用户密码不对，则返回http code 401页面给客户端。

base64在线编码j解码工具：http://tool.chinaz.com/Tools/Base64.aspx

 Header:

 

Authorization   ： Basic YnJvd3Nlcjo=

 配置跨域访问问题：

/**
