集成SpringSecurity和Oauth2的授权码认证

一、授权码认证流程图

（A）用户访问客户端，后者将前者导向认证服务器。
（B）用户选择是否给予客户端授权。
（C）假设用户给予授权，认证服务器将用户导向客户端事先指定的"重定向URI"（redirection URI），同时附上一个授权码。
（D）客户端收到授权码，附上早先的"重定向URI"，向认证服务器申请令牌。这一步是在客户端的后台的服务器上完成的，对用户不可见。
（E）认证服务器核对了授权码和重定向URI，确认无误后，向客户端发送访问令牌（access token）和更新令牌（refresh token）。

二、授权码认证的优缺点

三、依赖配置（使用spring-cloud）

    <dependencies>
        <!--nacos 注册中心-->

    <dependencyManagement>
        <!--springCloud  基础依赖配置 很重要，如果没有，springCloud 就用不了-->

四、使用mybatis-plus自动生成代码

public class CodeGenerator {
    //程序入口
    public static void main(String[] args) {
        //创建代码生成器对象
        AutoGenerator mpg = new AutoGenerator();
        //全局设置
        GlobalConfig gc = new GlobalConfig();
        //设置输出路径
        gc.setOutputDir(System.getProperty("user.dir") + "/jyshop-test/src/main/java");
        //设置作者
        gc.setAuthor("liuhao");
        //生成是否打开文件
        gc.setOpen(false);
        //全局设置
        mpg.setGlobalConfig(gc);
        //设置生成返回的结果集
        gc.setBaseResultMap(true);
        gc.setBaseColumnList(true);

        //数据源配置
        DataSourceConfig dsc = new DataSourceConfig();
        //设置驱动类
        dsc.setDriverName("com.mysql.jdbc.Driver");
        //设置的url
        dsc.setUrl("jdbc:mysql://localhost:3306/1707a?useUnicode=true&useSSL=false&characterEncoding=utf8&serverTimezone=UTC");
        //设置用户名
        dsc.setUsername("root");
        //设置密码
        dsc.setPassword("root");
        //设置代码生成器对象的数据
        mpg.setDataSource(dsc);


        //设置生成到到哪里 包
        PackageConfig pc = new PackageConfig();
        //设置包名称
        pc.setParent(CodeGenerator.class.getPackage().getName());
        //设置包的路径com.bawei.bootplus /entity/service/mapper/controller
        mpg.setPackageInfo(pc);


        //生成的策略
        StrategyConfig strategy = new StrategyConfig();
        //生成那些表
        strategy.setInclude("t_user");
        //排除表
        //strategy.setExclude("t_user");
        //表的前缀
        strategy.setTablePrefix("t_");
        //strategy.setFieldPrefix()
        //采用lombok处理
        strategy.setEntityLombokModel(true);

        //设置生成策略
        mpg.setStrategy(strategy);


        //执行生成
        mpg.execute();
    }
}

五、需要添加的配置类
