hello 文档

package org.springframework.security.samples.config;
​
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
​
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
​
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .authorizeRequests()
                .antMatchers("/css/**", "/index").permitAll()    //所有人可以访问  
                .antMatchers("/user/**").hasRole("USER")        //指定角色可以访问  
                .and()
            .formLogin()
                .loginPage("/login").failureUrl("/login-error");//设置登录，和登录失败页
    }
​
    //设置用户的权限
    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        auth
            .inMemoryAuthentication()
                .withUser("user").password("password").roles("USER");
    }
}

例子：

package com.atguigu.security.config;
​
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
​
@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，效果，如果没有登陆，没有权限就会来到登陆页面
        http.formLogin().usernameParameter("user").passwordParameter("pwd")
                .loginPage("/userlogin");
        //1、/login来到登陆页
        //2、重定向到/login?error表示登陆失败
        //3、更多详细规定
        //4、默认post形式的 /login代表处理登陆
        //5、一但定制loginPage；那么 loginPage的post请求就是登陆
​
​
        //开启自动配置的注销功能。
        http.logout().logoutSuccessUrl("/");//logoutSuccessUrl设置注销成功以后来的页面
        //1、访问 /logout 表示用户注销，清空session
        //2、注销成功会返回 /login?logout 页面；
​
        //开启记住我功能
        http.rememberMe().rememberMeParameter("remeber");
        //登陆成功以后，将cookie发给浏览器保存，以后访问页面带上这个cookie，只要通过检查就可以免登录
        //点击注销会删除cookie
​
    }
​
    //定义认证规则
    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        //super.configure(auth);
        auth.inMemoryAuthentication()
                .withUser("zhangsan").password("123456").roles("VIP1","VIP2")
                .and()
                .withUser("lisi").password("123456").roles("VIP2","VIP3")
                .and()
                .withUser("wangwu").password("123456").roles("VIP1","VIP3");
​
    }
}
