JWT教程_3 oauth和JWT 整合

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.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.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;


@Configuration
@EnableWebSecurity
public class SpringSecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        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()
                .anyRequest().authenticated();
        http.csrf().disable();

    }

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

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

• 输入

package com.example.demo3.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class LoginDemo {

    @RequestMapping("/myLoginController")
    public String myLogin(){
        return "myLogin";
    }

    @RequestMapping("/toSuccess")
    public String toSuccess(){
        return "success";
    }

    @RequestMapping("/toFail")
    public String toFail(){
        return "fail";
    }

}

• 资源网

package com.example.demo3.controller;


import org.springframework.security.core.Authentication;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/user")
public class UserController {

    @RequestMapping("/getCurrentUser")
    public Object kk(Authentication authentication){
        return authentication.getPrincipal();
    }
}

• userDetails

package com.example.demo3.service;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.authority.AuthorityUtils;
import org.springframework.security.core.userdetails.User;
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.password.PasswordEncoder;
import org.springframework.stereotype.Service;

@Service
public class LoginService implements UserDetailsService {

    @Autowired
    PasswordEncoder passwordEncoder;

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        // 自定义 用户登录名
        if(!username.equals("admin")){
            throw  new UsernameNotFoundException("这是俺自己写的错误");
        }

        String password=passwordEncoder.encode("123");
        return new User(username,password, AuthorityUtils.commaSeparatedStringToAuthorityList("admin,ROLE_abc"));
    }
}
