springsecurity-oauth2之基础知识介绍(一)

1.公钥与私钥

本项目采用JWT令牌生成采用非对称加密算法。

1.1 自己电脑上安装 Win64OpenSSL-1_1_1b.exe

1.2 找一个文件夹使用cmd命令打开dos命令窗口，输入：

 keytool -genkeypair -alias macrosoft -keyalg RSA -keypass 420188 -keystore macrosoft.jks -storepass 420188

这样会生成一个密钥对的文件,叫 macrosoft.jks,它供认证服务器使用,现在要获取公钥供资源服务器使用。

1.3 获取公钥

在上面macrosoft.jks所在文件夹打开dos命令窗口,输入：

keytool -list -rfc --keystore macrosoft.jks | openssl x509 -inform pem -pubkey

会输入密钥库密码，即上面的storepass。
生成了公钥, 特别注意生成的公钥最后一个 - 但实际上是5个 粘的时候要加上。即：从-----BEGIN 开始到END PUBLIC KEY----- 结束。
把它粘贴到一行,放入public.key文件，并粘到资源服务器的resource目录下，和面好使用。
在这里插入图片描述

原理：认证服务器在生成token时会用到密钥对文件,即这里的 macrosoft.jks,资源服务器在解密的时候会用到公钥,即自己放入公钥的public.key文件。

2.关于资源服务器的认证

2.1 资源服务器的配置

 @Configuration
@EnableResourceServer
public class OAuth2ResourceServer extends ResourceServerConfigurerAdapter {

    private static final String DEMO_RESOURCE_ID = "res1";
    @Override
    public void configure(ResourceServerSecurityConfigurer resources) {
        resources.resourceId(DEMO_RESOURCE_ID)
        //...... 还可以有有其他的配置
    }
 }

2.2 AuthorizationServer如何设置ResourceIDs?

在AuthorizationServer为客户端client配置ResourceID的目的是：限制某个client可以访问的资源服务

 @Override
public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
    //配置客户端存储到db 代替原来得内存模式
    JdbcClientDetailsService clientDetailsService = new JdbcClientDetailsService(dataSource);
    clientDetailsService.setPasswordEncoder(passwordEncoder);

这里需要使用JdbcClientDetailsService类和数据库表oauth_client_details进行配置的持久化存储，以及动态配置

2.3 ResourceID在哪验证?

注意：这里资源服务器不仅仅是通过RESOURCE_ID来控制访问权限, 还通过scope来控制:

  @Override
    public void configure(HttpSecurity http) throws Exception {
        http
                .authorizeRequests()
                .antMatchers("/**")
                .access("#oauth2.hasScope('ROLE_USER')")
                .and().csrf().disable()
                .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);

在oauth_client_details中对应的clientId、clientSecret对应的数据的字段scope必须包含当前资源服务器中的#oauth2.hasScope(‘ROLE_USER’)配置才能访问

3.sql文件准备
