session和token的区别：
Oauth3 密码授权流程
在oauth3协议里，每一个应用都有自己的一个clientId和clientSecret（需要去认证方申请），所以一旦想通过认证，必须要有认证方下发的clientId和secret。
1. pom
org.springframework.boot
spring-boot-starter-security
org.springframework.security.oauth
spring-security-oauth3
2. UserDetail实现认证第一步
MyUserDetailsService.java
@Autowired
private PasswordEncoder passwordEncoder;
/**
* 根据进行登录
* @param username
* @return
* @throws UsernameNotFoundException
*/
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
log.info("登录用户名:"+username);
String password = passwordEncoder.encode("123456");
//User三个参数 (用户名+密码+权限)
//根据查找到的用户信息判断用户是否被冻结
log.info("数据库密码:"+password);
return new User(username,password, AuthorityUtils.commaSeparatedStringToAuthorityList("admin"));
}3. 获取token的控制器
@RestController
public class OauthController {
@Autowired
private ClientDetailsService clientDetailsService;
@Autowired
private AuthorizationServerTokenServices authorizationServerTokenServices;
@Autowired
private AuthenticationManager authenticationManager;
@PostMapping("/oauth/getToken")
public Object getToken(@RequestParam String username, @RequestParam String password, HttpServletRequest request) throws IOException {
Mapmap = new HashMap<>(8);
//进行验证
String header = request.getHeader("Authorization");
if (header == null && !header.startsWith("Basic")) {
map.put("code",500);
map.put("message","请求投中无client信息");
return map;
}
String[] tokens = this.extractAndDecodeHeader(header, request);
assert tokens.length == 2;
//获取clientId 和 clientSecret
String clientId = tokens[0];
String clientSecret = tokens[1];
//获取 ClientDetails
ClientDetails clientDetails = clientDetailsService.loadClientByClientId(clientId);
if (clientDetails == null){
map.put("code",500);
map.put("message","clientId 不存在"+clientId);
return map;
//判断 方言 是否一致
}else if (!StringUtils.equals(clientDetails.getClientSecret(),clientSecret)){
map.put("code",500);
map.put("message","clientSecret 不匹配"+clientId);
return map;
}
//使用username、密码进行登录
UsernamePasswordAuthenticationToken authentication = new UsernamePasswordAuthenticationToken(username, password);
//调用指定的UserDetailsService，进行用户名密码验证
Authentication authenticate = authenticationManager.authenticate(authentication);
HrUtils.setCurrentUser(authenticate);
//放到session中
//密码授权 模式, 组建 authentication
TokenRequest tokenRequest = new TokenRequest(new HashMap<>(),clientId,clientDetails.getScope(),"password");
OAuth3Request oAuth3Request = tokenRequest.createOAuth3Request(clientDetails);
OAuth3Authentication oAuth3Authentication = new OAuth3Authentication(oAuth3Request,authentication);
OAuth3AccessToken token = authorizationServerTokenServices.createAccessToken(oAuth3Authentication);
map.put("code",200);
map.put("token",token.getValue());
map.put("refreshToken",token.getRefreshToken());
return map;
}
/**
* 解码请求头
*/
private String[] extractAndDecodeHeader(String header, HttpServletRequest request) throws IOException {
byte[] base64Token = header.substring(6).getBytes("UTF-8");
byte[] decoded;
try {
decoded = Base64.decode(base64Token);
} catch (IllegalArgumentException var7) {
throw new BadCredentialsException("Failed to decode basic authentication token");
}
String token = new String(decoded, "UTF-8");
int delim = token.indexOf(":");
if (delim == -1) {
throw new BadCredentialsException("Invalid basic authentication token");
} else {
return new String[]{token.substring(0, delim), token.substring(delim + 1)};
}
}
} 4. 核心配置
（1）、Security 配置类 说明登录方式、登录页面、哪个url需要认证、注入登录失败/成功过滤器
@Configuration
public class BrowserSecurityConfig extends WebSecurityConfigurerAdapter {
/**
* 注入 自定义的 登录成功处理类
*/
@Autowired
private MyAuthenticationSuccessHandler mySuccessHandler;
/**
* 注入 自定义的 登录失败处理类
*/
@Autowired
private MyAuthenticationFailHandler myFailHandler;
@Autowired
private ValidateCodeFilter validateCodeFilter;
/**
* 重写PasswordEncoder 接口中的方法，实例化加密策略
* @return 返回 BCrypt 加密策略
*/
@Bean
public PasswordEncoder passwordEncoder(){
return new BCryptPasswordEncoder();
}
@Override
protected void configure(HttpSecurity http) throws Exception {
//在UsernamePasswordAuthenticationFilter 过滤器前 加一个过滤器 来搞验证码
http.addFilterBefore(validateCodeFilter, UsernamePasswordAuthenticationFilter.class)
//表单登录 方式
.formLogin()
.loginPage("/authentication/require")
//登录需要经过的url请求
.loginProcessingUrl("/authentication/form")
.passwordParameter("pwd")
.usernameParameter("user")
.successHandler(mySuccessHandler)
.failureHandler(myFailHandler)
.and()
//请求授权
.authorizeRequests()
//不需要权限认证的url
.antMatchers("/oauth/*","/authentication/*","/code/image").permitAll()
//任何请求
.anyRequest()
//需要身份认证
.authenticated()
.and()
//关闭跨站请求防护
.csrf().disable();
//默认注销地址：/logout
http.logout().
//注销之后 跳转的页面
logoutSuccessUrl("/authentication/require");
}
/**
* 认证管理
*
* @return 认证管理对象
* @throws Exception 认证异常信息
*/
@Override
@Bean
public AuthenticationManager authenticationManagerBean() throws Exception {
return super.authenticationManagerBean();
}
}（2）、认证服务器
@Configuration
@EnableAuthorizationServer
public class MyAuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {
@Autowired
private AuthenticationManager authenticationManager;
@Autowired
private MyUserDetailsService userDetailsService;
@Override
public void configure(AuthorizationServerSecurityConfigurer security) throws Exception {
super.configure(security);
}
/**
* 客户端配置（给谁发令牌）
* @param clients
* @throws Exception
*/
@Override
public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
clients.inMemory().withClient("internet_plus")
.secret("internet_plus")
//有效时间 2小时
.accessTokenValiditySeconds(72000)
//密码授权模式和刷新令牌
.authorizedGrantTypes("refresh_token","password")
.scopes( "all");
}
@Override
public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
endpoints
.authenticationManager(authenticationManager)
.userDetailsService(userDetailsService);
}
}@EnableResourceServer这个注解就决定了这是个资源服务器。它决定了哪些资源需要什么样的权限。
