### SpringBoot：整合SpringSecurity ###

*  一、项目结构
 *  二、pom
 *  三、编写SecurityConfig继承WebSecurityConfigurerAdapter
 *  四、首页

# 一、项目结构 #

        </build>
    
    </project>

# 三、编写SecurityConfig继承WebSecurityConfigurerAdapter #

@EnableWebSecurity
    public class SecurityConfig extends WebSecurityConfigurerAdapter { 
    // 授权
        @Override
        protected void configure(HttpSecurity http) throws Exception { 
            //请求授权规则
            http.authorizeRequests()
                    //首页所有人可以访问
                    //vip每种等级对应不同的角色
                    .antMatchers("/").permitAll()
                    .antMatchers("/vip1/**").hasRole("vip1")
                    .antMatchers("/vip2/**").hasRole("vip2")
                    .antMatchers("/vip3/**").hasRole("vip3");
    
            //没有权限默认到登录页面
            http.formLogin().loginPage("/tologin").usernameParameter("username").passwordParameter("pwd").loginProcessingUrl("/login");
            //开启注销功能,注销成功跳到首页
            http.csrf().disable();
            http.logout().logoutSuccessUrl("/");
            //记住我
            http.rememberMe().rememberMeParameter("remember");
        }
    
    //    认证
        @Override
        protected void configure(AuthenticationManagerBuilder auth) throws Exception { 
            //这里从内存中读取用户
            auth.inMemoryAuthentication().passwordEncoder(new BCryptPasswordEncoder())
                    .withUser("kexing").password(new BCryptPasswordEncoder().encode("123456")).roles("vip1")
                    .and()
                    .withUser("root").password(new BCryptPasswordEncoder().encode("123456")).roles("vip1","vip2","vip3");
        }
    }

这里总共设置了三种角色对应不同的访问权限，首页允许所有人访问，这里更改了`springsecurity`自带的登录页面：  
`http.formLogin`()：没有权限默认到登录页面  
`loginPage`（）：用户未登录时，访问任何资源都转跳到该路径，即登录页面  
`loginProcessingUrl`（）：登录表单`form`中`action`的地址，也就是处理认证请求的路径  
`usernameParameter`（）：登录表单`form`中用户名输入框`input`的`name`名，不修改的话默认是`username`  
`passwordParameter`（）：登录表单`form`中用户名输入框`input`的`name`名，不修改的话默认是`password`

**springsecurity中需要对传输的明文密码加密，这里选用的BCrypt加密方法，重新对password进行编码**  
**因为没有连数据库，所以这里我模拟的是从内存中认证用户**

# 四、首页 #

首页中当用户未登录时，显示登陆按钮；当用户登录时，显示用户名，权限，注销按钮  
**因为不同用户拥有不同的角色，也就是不同的权限，所以首页需要展示给用户的则是该用户拥有的权限对应的版块，也就是实现动态菜单**

**引入sec命名空间**：`xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity5"`

`sec:authorize="isAuthenticated()"` 用于判断该用户是否被认证，也就是是否登录  
`sec:authorize="hasRole('vip1')"` 只允许对应角色访问

**因为前面的`config`类中已经对用户进行了角色认证，用户`kexing`的权限只能访问vip1，用户`root`的权限可以访问vip1，vip2，vip3所有权限**

**未登录时：**
