SpringSecurity 入坑第一步:内存的权限验证与受权

构建权限验证
package com.shaojie.authority.security;

import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
/**

*/
@Configuration
// 启动 SpringSecurity 的过滤器链
@EnableWebSecurity
public class SpringSecurityConfig extends WebSecurityConfigurerAdapter {
@Bean
public BCryptPasswordEncoder passwordEncoder() {return new BCryptPasswordEncoder();
}
/**

*/
// 代替配置文件 <security:authentication-manager></security:authentication-manager>
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {// 老版本的角色设置 在 springboot 2.0 当前 不能这样设置
// auth.inMemoryAuthentication()
// .withUser(“shaojie”).password(“123456”)

// inMemoryAuthentication 内存验证
auth.inMemoryAuthentication()
.passwordEncoder(passwordEncoder())
.withUser("shaojie")
.password(passwordEncoder().encode("123456"))
// .roles("PRODUCT_ADD","PRODUCT_LIST");

.authorities("PRODUCT_ADD", "PRODUCT_LIST");
}
/**

构建谬误页面配置
验证没有权限时跳转
package com.shaojie.authority.security;
import org.springframework.boot.web.server.ConfigurableWebServerFactory;
import org.springframework.boot.web.server.ErrorPage;
import org.springframework.boot.web.server.WebServerFactoryCustomizer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.HttpStatus;
/**
- @author ShaoJie
- @Date 2019/10/25
*/
@Configuration
public class ErrorPageConfig {
// 应用 WebServerFactoryCustomizer 接口替换 EmbeddedServletContainerCustomizer 组件实现对嵌入式 Servlet 容器的配置
@Bean
public WebServerFactoryCustomizer<ConfigurableWebServerFactory> webServerFactoryCustomizer(){return new WebServerFactoryCustomizer<ConfigurableWebServerFactory>() {
@Override
public void customize(ConfigurableWebServerFactory factory) {factory.addErrorPages(new ErrorPage(HttpStatus.FORBIDDEN,"/403"));
}
};
}
}
login.html
<!DOCTYPE html>
<html lang=”en” xmlns:th=”http://www.thymeleaf.org”>

值得注意一下这里的 <input> 的属性 name
官网源码 写的很分明 默认就是 username 和 password
* protected void configure(HttpSecurity http) throws Exception {* http.authorizeRequests().antMatchers("/**").hasRole("USER").and().formLogin()
* .usernameParameter("username") // default is username
* .passwordParameter("password") // default is password
* .loginPage("/authentication/login") // default is /login with an HTTP get
* .failureUrl("/authentication/login?failed") // default is /login?error

整体应用内存做受权验证,后续整顿基于 JDBC 做权限受权,整体一套下来的话,基本上对于 springsecurity 有一个根本的理解,入坑第一步倡议以根底动手,大部分的配置倡议查看官网源码,对于登出以及记住明码,细节在 源码 HttpSecurity 类中有具体阐明,这里不做过多的阐明。只提供根底的 Demo 示例
