Spring Boot整合Spring Security的demo
1、引入SpringSecurity
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
2、编写SpringSecurity的配置类
官网链接:https://spring.io/projects/spring-security
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("/");//注销成功以后来到首页
//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");
}
}
3、控制请求的访问权限:
configure(HttpSecurity http) {
http.authorizeRequests().antMatchers("/").permitAll()
.antMatchers("/level1/**").hasRole("VIP1")
}
4、定义认证规则:
configure(AuthenticationManagerBuilder auth){
auth.inMemoryAuthentication()
.withUser("zhangsan").password("123456").roles("VIP1","VIP2")
}
5、开启自动配置的登陆功能:
configure(HttpSecurity http){
http.formLogin();
}
6、注销:http.logout();
//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;
7、记住我:Remeberme();
//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
