Spring Security是针对Spring项目的安全框架,也是Spring Boot底层安全模块默认的技术选型。他能够实现强大的web安全控制。对于安全控制,咱们仅需引入spring-boot-starter-security模块,进行少许的配置,便可实现强大的安全管理。html
WebSecurityConfigurerAdapter:自定义Security策略web
AuthenticationManagerBuilder:自定义认证策略spring
@EnableWebSecurity:开启WebSecurity模式安全
应用程序的两个主要区域是'认证'和'受权'(或者访问控制)。app
'认证'和'受权'主要区域是Spring Security 的两个目标。框架
认证(Authentication),是创建一个他声明的主体的过程(一个'主体'通常是指用户,设备或一些能够在你的应用程序中执行动做的其余系统)ide
'受权'(Authorization)指肯定一个主体是否容许在你的应用程序执行一个动做的过程。为了抵达须要受权的店,主体的身份已经有认证过程创建。spring-boot

HttpSecurity配置登录、注销功能
package com.hosystem.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.builders.WebSecurity; import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity; import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter; import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
@EnableWebSecurity public class MySecurityConfig extends WebSecurityConfigurerAdapter{
//定义受权规则 @Override protected void configure(HttpSecurity http) throws Exception { // super.configure(http);
//定制请求的受权规则 http.authorizeRequests().antMatchers("/").permitAll() .antMatchers("/level1/**").hasRole("VIP1") .antMatchers("/level2/**").hasRole("VIP2") .antMatchers("/level3/**").hasRole("VIP3");
//开启自动配置登陆功能 http.formLogin(); //1. /login到登陆页 //2. 重定向到/login?error表示登陆失败 //3. 更多详细规定 }
//定义认证规则 @Override protected void configure(AuthenticationManagerBuilder auth) throws Exception { // super.configure(auth);
auth.inMemoryAuthentication().passwordEncoder(new BCryptPasswordEncoder()) .withUser("tom").password(new BCryptPasswordEncoder().encode("123456")).roles("VIP1","VIP2") .and() .withUser("jack").password(new BCryptPasswordEncoder().encode("123456")).roles("VIP2","VIP3") .and() .withUser("lucy").password(new BCryptPasswordEncoder().encode("123456")).roles("VIP1","VIP3");
} } |
注:若是出现There is no PasswordEncoder mapped for the id “null”
或者 Encoded password does not look like bcrypt(Bad credentials)基本都是springsecurity版本的问题。只须要使用passwordEncoder(new BCryptPasswordEncoder())替换原来的便可。
#老版本springsecurity auth.inMemoryAuthentication().withUser("user").password("123456").roles("VIP1");
#新版本springsecurity auth.inMemoryAuthentication().passwordEncoder(new BCryptPasswordEncoder()) .withUser("tom").password(new BCryptPasswordEncoder().encode("123456")).roles("VIP1","VIP2"); |
