# 4. oauth和JWT 整合 #

*  编写jwt 类
    
        package com.example.demo3.config;
        
        import org.springframework.context.annotation.Bean;
        import org.springframework.context.annotation.Configuration;
        import org.springframework.security.jwt.Jwt;
        import org.springframework.security.oauth2.provider.token.TokenStore;
        import org.springframework.security.oauth2.provider.token.store.JwtAccessTokenConverter;
        import org.springframework.security.oauth2.provider.token.store.JwtTokenStore;
        
        @Configuration
        public class JwtTokenStoreConfig { 
        
            @Bean
            public TokenStore tokenStore(){ 
                return new JwtTokenStore(jwtAccessTokenConverter());
            }
        
            @Bean
            public JwtAccessTokenConverter jwtAccessTokenConverter(){ 
                JwtAccessTokenConverter jwtAccessTokenConverter=new JwtAccessTokenConverter();
                jwtAccessTokenConverter.setSigningKey("xxxx");
                return jwtAccessTokenConverter;
            }
        }
 *  编写服务器类
    
        package com.example.demo3.config;
        
        
        
        import com.example.demo3.service.LoginService;
        import org.springframework.beans.factory.annotation.Autowired;
        import org.springframework.beans.factory.annotation.Qualifier;
        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.configuration.EnableAuthorizationServer;
        import org.springframework.security.oauth2.config.annotation.web.configurers.AuthorizationServerEndpointsConfigurer;
        import org.springframework.security.oauth2.provider.token.TokenStore;
        import org.springframework.security.oauth2.provider.token.store.JwtAccessTokenConverter;
        import org.springframework.security.oauth2.provider.token.store.JwtTokenStore;
        
        /** * 这个是授权服务器 * 功能类似于 微信，qq 等大场企业 */
        @Configuration
        @EnableAuthorizationServer
        public class AuthorizationServiceConfig extends AuthorizationServerConfigurerAdapter { 
        
            @Autowired
            private PasswordEncoder encoder;
        
            @Autowired
            private AuthenticationManager authenticationManager;
        
            @Autowired
            private TokenStore jwtTokenStore;
        
            @Autowired
            private JwtAccessTokenConverter jwtAccessTokenConverter;
        
        
        
            @Autowired
            LoginService service;
            @Override
            public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception { 
               endpoints.authenticationManager(authenticationManager)
                       .userDetailsService(service)
                       .tokenStore(jwtTokenStore)
                       .accessTokenConverter(jwtAccessTokenConverter);
            }
        
            @Override
            public void configure(ClientDetailsServiceConfigurer clients) throws Exception { 
               clients.inMemory()
               .withClient("wechat")
                       .secret(encoder.encode("112233")) // 秘钥
                       .redirectUris("https://www.baidu.com") //重定向服务器配置
                       .scopes("all")// 授权范围
                       .authorizedGrantTypes("authorization_code","password");
            }
        }
 *  编写服务器类
    
        package com.example.demo3.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;
        
        
        /** * 这个是类似于 微信 qq 等大场的资源 */
        @Configuration
        @EnableResourceServer
        public class ResourceConfig extends ResourceServerConfigurerAdapter { 
            @Override
            public void configure(HttpSecurity http) throws Exception { 
                http.csrf().disable();
                http.authorizeRequests()
                        .anyRequest()
                        .authenticated()
                        .and()
                        .requestMatchers()
                        .antMatchers("/user/**");
            }
        }
 *  编写config
    
        package com.example.demo3.config;
        
        
        import org.springframework.context.annotation.Bean;

        import org.springframework.security.crypto.password.PasswordEncoder;
        
        
        @Configuration
        @EnableWebSecurity

                http.formLogin()
                        .loginPage("/myLoginController") // 一定要和 Controller 中 返回 myLogin页面 一致，
                        .loginProcessingUrl("/login");// 必须和表单提交 action 的名字 一样的，提交 username 和password
                     // .successForwardUrl("/toSuccess");// 这个是 登录成功后返回的界面
        
                http.authorizeRequests()
                        .antMatchers("/myLoginController").permitAll()// 放行myLoginController
                        .antMatchers("/oauth/**","/login/**","/logout/**").permitAll()
