2020-03-1812:50:53springboot与安全之spring Security Demo版

注解：@EnableWebSecurity

WebSecurityConfigurerAdapter：自定义Security策略

AuthenticationManagerBuilder：自定义认证策略

HttpSecurity配置登陆、注销功能

官方文档：https://spring.io/guides/gs/securing-web/

注意：将thymeleaf的依赖加入

注意版本要保持一致，如果版本不一致可能需要自己去调程序，目前没能自己调通springboot 2.xx版本

springsecurity核心代码：

import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;

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

@EnableWebSecurity
public class MySecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        //super.configure(http);
        //定制请求的授权规则
        http.authorizeRequests().antMatchers("/").permitAll()
                .antMatchers("/level1/**").hasRole("VIP1")
                .antMatchers("/level2/**").hasRole("VIP2")
                .antMatchers("/level3/**").hasRole("VIP3");
        //开启自动配置的登陆功能
        //定制loginPage后，loginPage的post请求就是登陆
        http.formLogin().usernameParameter("user").passwordParameter("pwd").loginPage("/userLogin");

        //开启自动配置的注销功能
        //logoutSuccessUrl:注销成功后请求的地址
        http.logout().logoutSuccessUrl("/");

        //记住我功能
        //rememberMeParameter：记住我功能的参数
        http.rememberMe()/*.rememberMeParameter("remeber")*/;
    }

    //定义认证规则
    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        //super.configure(auth);
        //基于内存的
        //https://blog.csdn.net/syc000666/article/details/96862574
