Spring Security学习笔记（一）

介绍

这里学习SpringSecurity，对SpringSecurity进行学习。

基本用法

添加依赖

<dependency>
 <groupId>org.springframework.boot</groupId>
 <artifactId>spring-boot-starter-security</artifactId>
</dependency>

添加接口

package com.example.demo.web;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/test")
public class Test {
 @RequestMapping("/test")
 public String test(){
   return "test";
 }
}

启动项目

可以看到日志中，已经有了密码

访问接口，此时已经有了登录页面

输入用户名和密码

用户名： user
密码 984cccf2-ba82-468e-a404-7d32123d0f9c

此时已经登录成功

配置用户名和密码

在配置文件中，进行配置

spring:
security:
user:
name: ming
password: 123456
roles: admin

输入用户名和密码，可以正常登录

基于内存的认证

需要自定义类继承 WebSecurityConfigurerAdapter
实现自定义的配置
这里基于内存的配置，如下

package com.example.demo.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.crypto.password.NoOpPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;

@Configuration
public class MyWebSecurityConfig extends WebSecurityConfigurerAdapter {
 @Bean
 PasswordEncoder passwordEncoder(){
   return NoOpPasswordEncoder.getInstance();
 }

@Override
 protected void configure(AuthenticationManagerBuilder auth) throws Exception {
   auth.inMemoryAuthentication()
       .withUser("admin").password("123").roles("admin");
 }
}

这里基于内存的配置

HttpSecurity

这里对某些方法进行拦截

package com.ming.demo.interceptor;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.HttpMethod;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;
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;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.security.web.authentication.rememberme.TokenBasedRememberMeServices;

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
 //基于内存的用户存储
 @Override
 public void configure(AuthenticationManagerBuilder auth) throws Exception {
   auth.inMemoryAuthentication()
       .withUser("itguang").password("123456").roles("USER").and()
       .withUser("admin").password("{noop}" + "123456").roles("ADMIN");
 }

//请求拦截
 @Override
 protected void configure(HttpSecurity http) throws Exception {
   http.authorizeRequests()
       .anyRequest().permitAll()
       .and()
       .formLogin()
       .permitAll()
       .and()
       .logout()
       .permitAll();
 }

}

这里成功完成了post请求进行登录验证。
