一、Spring Security简介

Spring Security 是一个功能强大且高度可定制的身份验证和访问控制框架。它是用于保护基于Spring的应用程序的实际标准。

二、搭建环境

1.在pom.xml中添加相关依赖 

<?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 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
 
    <groupId>org.example</groupId>
    <artifactId>springsecurityReview</artifactId>
    <version>1.0-SNAPSHOT</version>
 
    <parent>
        <artifactId>spring-boot-dependencies</artifactId>
        <groupId>org.springframework.boot</groupId>
        <version>2.5.4</version>
    </parent>
 
    <dependencies>
        <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>
 
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-thymeleaf</artifactId>
        </dependency>
    </dependencies>
</project>

2.创建Handler类 

package com.example.controller;
 
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
 
@Controller
public class Handler {
    @GetMapping("/index")
    public String index(){
        return "index";
    }
}

3.创建简单的html文件和配置相关thymeleaf路径

4.添加启动类 

package com.example;
 
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
 
@SpringBootApplication
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class,args);
    }
}

5.自定义用户密码
