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();
  }
}
