Spring security oauth2 client_credentials认证 最简单示例代码

基于spring-boot-2.0.0

1，在pom.xml中添加：

        <!-- security -->
        <!-- https://mvnrepository.com/artifact/org.springframework.security.oauth/spring-security-oauth2 -->
        <dependency>
            <groupId>org.springframework.security.oauth</groupId>
            <artifactId>spring-security-oauth2</artifactId>
            <version>2.3.0.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-security</artifactId>
        </dependency>

2，ServerConfig

package com.italkbb.homesecurity.alertmessage.security;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
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.AuthorizationServerSecurityConfigurer;

@Configuration
@EnableAuthorizationServer
//提供/oauth/authorize,/oauth/token,/oauth/check_token,/oauth/confirm_access,/oauth/error
public class OAuth2ServerConfig extends AuthorizationServerConfigurerAdapter {
    @Autowired
    PasswordEncoder bCryptPasswordEncoder;//定义在SecurityConfig 中@Bean public PasswordEncoder passwordEncoder()

    @Override
    public void configure(AuthorizationServerSecurityConfigurer oauthServer) throws Exception {
        oauthServer.tokenKeyAccess("permitAll()")
        .checkTokenAccess("isAuthenticated()") //allow check token
        .allowFormAuthenticationForClients();
    }

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.inMemory()
            .withClient("app")
            .secret(bCryptPasswordEncoder.encode("app"))
            .authorizedGrantTypes("client_credentials", "password", "refresh_token")
            .scopes("all")
            .resourceIds("oauth2-resource")

            .and()

            .withClient("app1")
            .secret(bCryptPasswordEncoder.encode("app1"))
            .authorizedGrantTypes("client_credentials", "password", "refresh_token")
            .scopes("all")
            .resourceIds("oauth2-resource1")

            .accessTokenValiditySeconds(1200)
            .refreshTokenValiditySeconds(50000)

        ;

    }

}

3，ResourceServerConfig

package com.italkbb.homesecurity.alertmessage.security;

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

@Configuration
@EnableResourceServer
public class ResourceServerConfig extends ResourceServerConfigurerAdapter {

}

4，SecurityConfig

package com.italkbb.homesecurity.alertmessage.security;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.web.servlet.FilterRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
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.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.factory.PasswordEncoderFactories;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.web.cors.CorsConfiguration;
import org.springframework.web.cors.UrlBasedCorsConfigurationSource;
import org.springframework.web.filter.CorsFilter;

/**
 * Created by wangyunfei on 2017/6/9.
 */
@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Autowired
    private DomainUserDetailsService userDetailsService;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .csrf().disable()
                .anonymous().disable()
                .authorizeRequests()
                .antMatchers("/api-docs/**")//至少需要一个
                .permitAll();
    }

    @Bean
    public FilterRegistrationBean corsFilter() {
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        CorsConfiguration config = new CorsConfiguration();
        config.setAllowCredentials(true);
        config.addAllowedOrigin("*");
        config.addAllowedHeader("*");
        config.addAllowedMethod("*");
        source.registerCorsConfiguration("/**", config);
        FilterRegistrationBean bean = new FilterRegistrationBean(new CorsFilter(source));
        bean.setOrder(0);
        return bean;
    }

    @Bean
    public DomainUserDetailsService userDetailsService(){
        return new DomainUserDetailsService();
    }

    @Bean
    public PasswordEncoder passwordEncoder() {
        System.out.println("============================passwordEncoder  ");
//        return PasswordEncoderFactories.createDelegatingPasswordEncoder();
        return new BCryptPasswordEncoder();
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        System.out.println("============================configure  ");
        auth.userDetailsService(userDetailsService()).passwordEncoder(passwordEncoder());
    }

    //不定义没有password grant_type
    @Override
    @Bean
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }

    class DomainUserDetailsService implements UserDetailsService {
        @Autowired
        PasswordEncoder bCryptPasswordEncoder;

        @Override
        public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
            System.out.println("============================loadUserByUsername  "+username);
             return new User("app",bCryptPasswordEncoder.encode("app"),null);
        }
    }

}

现在随便访问你的controller mapping，都说无权限。需要先获取token：

$ curl -H "Accept: application/json" http://localhost/oauth/token -d "grant_type=client_credentials&client_id=app&client_secret=app"

然后再去访问：

http://localhost/api/order/11?access_token=32f044cd-48ef-4382-9a77-7ee35bd9a824
