Spring Security 快速创建登录权限，安全管理资源权限

原文：https://ichochy.com/posts/spring/20211120.html

使用 Spring Security 合理配置页面权限，管理用户登录权限，实现页面安全

开发工具

创建项目

打开 IDEA 创建新项目 New Project，使用 start.spring.io 快速构建 16226365527086133

添加 Spring Web 依赖，finish 创建项目 16226367387048384

pom.xml 添加依赖

添加 Spring Security 依赖

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

编写项目

创建登录页面

templates/login.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Login</title>
</head>
<body>

<h1>Login</h1>

<div th:if="${param.error}">
    Invalid username and password.
</div>
<div th:if="${param.logout}">
    You have been logged out.
</div>
<form th:action="@{/login}" method="post">
    <div><label> User Name : <input type="text" name="username"/> </label></div>
    <div><label> Password: <input type="password" name="password"/> </label></div>
    <div><input type="submit" value="Sign In"/></div>
</form>

</body>
</html>

创建form表单，登录地址/login，方法为post

创建登出按钮

templates/index.html

<h1 th:inline="text">Hello [[${#httpServletRequest.remoteUser}]]!</h1>
<form th:action="@{/logout}" method="post">
    <input type="submit" value="Sign Out"/>
</form>

httpServletRequest.remoteUser获取当前登录用户

登出地址/logout，方法为post

配置 MvcConfig

创建com/ichochy/example/MvcConfig.java

/*
 * Copyright (c) 2021 iChochy
 * URL:https://ichochy.com
 * Date:2021/11/22 19:24:22
 */

package com.ichochy.example;

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

@Configuration
public class MvcConfig implements WebMvcConfigurer {
    public void addViewControllers(ViewControllerRegistry registry){
        registry.addViewController("/login").setViewName("login");
    }
}

添加登录页面控制器，指定地址/login

登录安全权限配置

创建 WebSecurityConfig，继承 WebSecurityConfigurerAdapter

/*

 * URL:https://ichochy.com
 * Date:2021/11/22 20:06:22
 */

package com.ichochy.example.login;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
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.core.userdetails.User;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.crypto.factory.PasswordEncoderFactories;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.security.provisioning.InMemoryUserDetailsManager;


@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .authorizeRequests()
                .antMatchers("/login").permitAll()
                .anyRequest().authenticated()
            .and()
            .formLogin()
                .loginPage("/login").permitAll()
            .and()
            .logout()
                .permitAll();
    }

    @Bean
    @Override
    public UserDetailsService userDetailsService(){
        PasswordEncoder encoder = PasswordEncoderFactories.createDelegatingPasswordEncoder();
        UserDetails userDetails = User.builder()
                .passwordEncoder(encoder::encode)
                .username("MLeo")
                .password("iChochy")
                .roles("iChochy")
                .build();
        return new InMemoryUserDetailsManager(userDetails);
    }
}

重写configure，配置登录权限，配置非认证（permitAll）地址和认证（authenticated）地址，loginPage自定义登录页面和权限，logout自定义登出页面和权限

userDetailsService方法设置用户登录信息存入内存，校验用户登录信息

运行项目

启动器 ExampleApplication

 * Date:2021/06/09 22:07:09
 */

package com.ichochy.example;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class ExampleApplication {

    public static void main(String[] args) {
        SpringApplication.run(ExampleApplication.class, args);
    }
}

Dubug 运行项目，启动成功后可以看到默认端口号为8080 16226399326197735

浏览器访问 http://localhost:8080，自动302重定向到登录页面 16378405780119936

登录成功页面 16378406340097327

总结

使用 Spring Security 管理登录权限，实现项目权限安全
