这节来完成spring oauth2功能的扩展。接前面的例子。

引入组件

引入spring-security-oauth2组件。

<dependency>
    <groupId>org.springframework.security.oauth</groupId>
    <artifactId>spring-security-oauth2</artifactId>
    <version>2.3.3.RELEASE</version>
</dependency>

配置Oauth2服务器

在com.biboheart.demo.user.security包中创建AuthorizationServerConfiguration，用来配置Oauth2服务

package com.biboheart.demo.user.security;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
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;
import org.springframework.security.oauth2.provider.approval.ApprovalStore;
import org.springframework.security.oauth2.provider.approval.TokenApprovalStore;

@Configuration
@EnableAuthorizationServer
public class AuthorizationServerConfiguration extends AuthorizationServerConfigurerAdapter {
    @Autowired
    @Qualifier("authenticationManagerBean")
    private AuthenticationManager authenticationManager;

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.inMemory()
            .withClient("client")
            .secret(new BCryptPasswordEncoder().encode("secret"))
            .authorizedGrantTypes("client_credentials", "password", "refresh_token", "authorization_code")
            .scopes("all")
            .autoApprove(true);
    }
    
    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
        endpoints
            .authenticationManager(this.authenticationManager);
    }
    
    @Override
    public void configure(AuthorizationServerSecurityConfigurer oauthServer)
            throws Exception {
        oauthServer
            .tokenKeyAccess("permitAll()")
            .checkTokenAccess("isAuthenticated()");
    }
    
    @Bean
    public ApprovalStore approvalStore() {
        TokenApprovalStore store = new TokenApprovalStore();
        return store;
    }
    
    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }

}

先使用内存客户端，后续再来转成数据库保存客户端。
创建类ResourceConfiguration，用来配置资源服务

package com.biboheart.demo.user.security;

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;

@Configuration
@EnableResourceServer
public class ResourceConfiguration extends ResourceServerConfigurerAdapter {
    @Override
    public void configure(HttpSecurity http) throws Exception {
        http
            .anonymous().disable()
            .requestMatchers()
                .antMatchers("/user/**")
                .and()
            .authorizeRequests()
                .antMatchers("/user/**").authenticated();
    }
}

创建MethodSecurityConfiguration类，用来开启函数的权限控制。可以在函数上面用注解的方式来判断权限。

package com.biboheart.demo.user.security;

import org.springframework.context.annotation.Configuration;
import org.springframework.security.access.expression.method.MethodSecurityExpressionHandler;
import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;
import org.springframework.security.config.annotation.method.configuration.GlobalMethodSecurityConfiguration;
import org.springframework.security.oauth2.provider.expression.OAuth2MethodSecurityExpressionHandler;

@Configuration
@EnableGlobalMethodSecurity(prePostEnabled = true, proxyTargetClass = true)
public class MethodSecurityConfiguration extends GlobalMethodSecurityConfiguration {
    @Override
    protected MethodSecurityExpressionHandler createExpressionHandler() {
        return new OAuth2MethodSecurityExpressionHandler();
    }
}

测试

使用API工具(postman)，测试获取access_token：
生成Authorization

Basic

Headers:

请求头

获取token
