spring boot 結合 security 和oauth 2.0 實現password受權

該文主要介紹 spring boot 結合spring security 和 spring oauth 2.0 實現password受權實例 ，

若是你對oauth 2.0協議不熟悉，請參考<a href="https://oauth.net/2/">OAuth 2.0</a>的詳細介紹，

spring oauth 2.0支持5鍾受權類型

受權類型                           實現類
authorization_code         AuthorizationCodeTokenGranter
refresh_token                  RefreshTokenGranter
implicit                            ImplicitTokenGranter
client_credentials            ClientCredentialsTokenGranter
password                        ResourceOwnerPasswordTokenGranter

其中要支持password受權類型 則須要 serverEndpointsConfig 中配置authenticationManager

下面是示例代碼

首先 你須要搭建一個基本的spint boot項目 若是不會搭建 請查看spring官網示例

本文采用maven管理項目

首先須要在maven中引入以下依賴

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.0.RELEASE</version>
    </parent>
    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.security.oauth</groupId>
            <artifactId>spring-security-oauth2</artifactId>
            <version>2.3.3.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-security</artifactId>
        </dependency>

接下來就是配置你的WebSecurity

package com.zb.spring.demo.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.authentication.builders.AuthenticationManagerBuilder;
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 WebSecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .authorizeRequests()
                .antMatchers("/oauth/**").permitAll()
                .and()
                .formLogin()
                .permitAll()
                .and()
                .logout()
                .permitAll();
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication().passwordEncoder(passwordEncoder())
                .withUser("user").password(passwordEncoder().encode("123456")).roles("user");
    }

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

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

最後配置你的AuthorizationServer

package com.zb.spring.demo.config;

import org.springframework.beans.factory.annotation.Autowired;
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.config.annotation.web.configurers.AuthorizationServerSecurityConfigurer;

@Configuration
@EnableAuthorizationServer
public class Oauth2ServerConfig extends AuthorizationServerConfigurerAdapter {
    @Autowired
    private PasswordEncoder passwordEncoder;

    @Autowired
    private AuthenticationManager authenticationManager;
    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.inMemory()
                .withClient("client")
                .authorizedGrantTypes("password", "refresh_token", "authorization_code")
                .scopes("select")
                .authorities("client")
                .secret(passwordEncoder.encode("123456"));
    }

    @Override
    public void configure(AuthorizationServerSecurityConfigurer security) throws Exception {
        security.tokenKeyAccess("permitAll()")
                .checkTokenAccess("permitAll()")
                .allowFormAuthenticationForClients();
    }

    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
        super.configure(endpoints);
        endpoints.authenticationManager(authenticationManager);
    }
}

配置完成以後使用http測試工具請求

請自行修改訪問服務端口號，

會得到以下的響應

{"access_token":"2de07324-1e45-4cdb-8635-2ab2fc6d6d9d","token_type":"bearer","refresh_token":"5120743f-1182-4ade-a8cc-a9665de537b2","expires_in":43199,"scope":"select"}

則說明獲取access_token成功。
