一、SpringSecurity+auth2.0系列（Basic基础认证）

Spring Security是一个能够为基于Spring的企业应用系统提供声明式的安全访问控制解决方案的安全框架。它提供了一组可以在Spring应用上下文中配置的Bean，充分利用了Spring IoC，DI（控制反转Inversion of Control ,DI:Dependency Injection 依赖注入）和AOP（面向切面编程）功能，为应用系统提供声明式的安全访问控制功能，减少了为企业系统安全控制编写大量重复代码的工作。
**Basic认证是一种较为简单的HTTP认证方式，客户端通过明文（Base64编码格式）传输用户名和密码到服务端进行认证，通常需要配合HTTPS来保证信息传输的安全。

新建springboot项目
1、pom如何下图所示：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.2.1.RELEASE</version><relativePath/> <!-- lookup parent from repository --></parent><groupId>com.thunisoft</groupId><artifactId>spring_security</artifactId><version>0.0.1-SNAPSHOT</version><name>spring_security</name><description>Demo project for Spring Boot</description><properties><java.version>1.8</java.version></properties><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency><!--  springboot 整合web组件--><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-security</artifactId></dependency></dependencies><build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin></plugins></build></project>

2、在包路径下新建config包
在包下新建配置类
完整代码如下

package com.thunisoft.spring_security.config;import org.springframework.context.annotation.Bean;
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.password.NoOpPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.stereotype.Component;@Component
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    //新增 HttpSecurity配置@Overrideprotected void configure(HttpSecurity http) throws Exception {
    http.authorizeRequests().antMatchers("/**").fullyAuthenticated().and().httpBasic();}/** 新增授权账户* */@Overrideprotected void configure(AuthenticationManagerBuilder auth) throws Exception {
    //新增一个用户为orange,密码为chengyunpeng的用户可以访问是所有权限auth.inMemoryAuthentication().withUser("orange").password("chengyunpeng").authorities("/");}/*** 密码不做任何处理* @return*/@Beanpublic static NoOpPasswordEncoder passwordEncoder(){
    return (NoOpPasswordEncoder) NoOpPasswordEncoder.getInstance();}
}

3、新建controller包
在包下新建controller类
完整类如下

package com.thunisoft.spring_security;import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;@RestController
public class UserController {@RequestMapping("/addMember")public String addMember(){return "添加用户";}
}

访问接口
http://127.0.0.1:8080/addMember

第一次访问需要输入配置的密码即可登录成功！
