SpringBoot整合SpringSecurity. 详细笔记 第二波

参考: https://www.bilibili.com/video/BV17h41147Jq

maven依赖

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-security</artifactId>
</dependency>

---发现加了依赖其实就生效了，访问 /login  就是security默认登录页面

账号 user  密码 在控制台打印有(每次启动都是不一样的)

查看密码加密后是否一致的方法 -----自定义登录需要，因为正常存入数据库密码为加密的，先用账户名查到对应密码 把前端传过来的密码加密看看是否和一致 

import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;

@GetMapping("/checkpwd")
    public boolean pwd() {
        PasswordEncoder pe =new BCryptPasswordEncoder();
        String encode =pe.encode("123");
        System.out.println(encode);
        return pe.matches("123",encode);
    }

    public PerformanceInterceptor PerformanceInterceptor(){
        PerformanceInterceptor PerformanceInterceptor = new PerformanceInterceptor();
        PerformanceInterceptor.setMaxTime(1111);//设置sql执行的最大时间,如果超过了则不执行，抛异常

//        这里也可以用.and()去接着连接

//                //持久层对象
                .tokenRepository(persistentTokenRepository);

        http.csrf().disable();//禁用跨站csrf攻击防御--开启后接口只需要传账号和密码 可做前后端分离 要加这个 或者等于关闭防火墙



//        自定义403等接口返回,异常处理
        http.exceptionHandling()
                .accessDeniedHandler(myAccessDeniedHandler);
