1：有basic模式认证：

1.0Maven依赖：

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.2.1.RELEASE</version>
</parent>
<dependencies>
 <!--  springboot 整合web组件-->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-security</artifactId>
    </dependency>
</dependencies>

1.1：重写这两个方法，一个拦截器`configure(HttpSecurity http)` ：，一个权限管理(过时)：`configure(AuthenticationManagerBuilder auth)`，整个security配置就是这两个方法在管理！

1.2：from表单模式：将上面的`.and().httpBasic();`改为`and().formLogin();`

1.3：多用户不同的权限：

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
//        /**
//         * 需要经过mayikt_admin
//         */
//        auth.inMemoryAuthentication().withUser("mayikt_admin").password("mayikt_admin").authorities("addMember",
//                "delMember", "updateMember", "showMember");
//        /**
//         * 当前 账户授权 可以访问哪些接口
//         */
//        auth.inMemoryAuthentication().withUser("mayikt_add").password("mayikt_add").authorities("addMember");
//        auth.inMemoryAuthentication().withUser("mayikt_update").password("mayikt_update").authorities("updateMember");
//        auth.inMemoryAuthentication().withUser("mayikt_show").password("mayikt_admin").authorities("showMember");
//        auth.inMemoryAuthentication().withUser("mayikt_del").password("mayikt_del").authorities("delMember");
        auth.userDetailsService(memberDetailsService).passwordEncoder(new PasswordEncoder() {
            @Override
            public String encode(CharSequence rawPassword) {
                return MD5Util.encode((String) rawPassword);
            }

            @Override
            public boolean matches(CharSequence rawPassword, String encodedPassword) {
                // md5 传递密码 传递密码 MD5 加密 ===DB中密码 密码输入正确的
                String rawPass = MD5Util.encode((String) rawPassword);
                boolean result = rawPass.equals(encodedPassword);
                return result;
            }
        });
    }
