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：

            <artifactId>spring-boot-starter-security</artifactId>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>

            </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
    @Override
    protected void configure(HttpSecurity http) throws Exception {
      http.authorizeRequests().antMatchers("/**").fullyAuthenticated().and().httpBasic();
    }


    /*
    * 新增授权账户
    * */
    @Override
    protected 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
     */
    @Bean
    public 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！
