SpringSecurity学习笔记

一、SpringSecurity官网

https://spring.io/projects/spring-security/https://spring.io/projects/spring-security/

Spring Security :: Spring Securityhttps://docs.spring.io/spring-security/reference/index.htmlJava Configuration :: Spring Securityhttps://docs.spring.io/spring-security/reference/5.7.2/servlet/configuration/java.html#page-title 二、新建项目

三、导入依赖

pom.xml

 
        
        
            org.springframework.boot
            spring-boot-starter-security
        
        
            org.springframework.boot
            spring-boot-starter-web
        

        
            org.springframework.boot
            spring-boot-starter-test
            test
        
        
        
        
            org.thymeleaf
            thymeleaf-spring5
        
        
            org.thymeleaf.extras
            thymeleaf-extras-java8time
        

    

application.yml

#关闭模板引擎缓存
spring:
  thymeleaf:
    cache: false

四、加入界面

五、建立RouterController 

RouterController.java类

package com.example.Controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;


@Controller
public class RouterController {

    @RequestMapping({"/","/index"})
    public String index(){
        return "index";
    }

    @RequestMapping("/toLogin")
    public String toLogin(){
        return "views/login";
    }

    @RequestMapping("/level1/{id}")
    public String level1(@PathVariable("id") int id){
        return "views/level1/"+id;
    }

    @RequestMapping("/level2/{id}")
    public String level2(@PathVariable("id") int id){
        return "views/level1/"+id;
    }

    @RequestMapping("/level3/{id}")
    public String level3(@PathVariable("id") int id){
        return "views/level1/"+id;
    }
}

四、SecurityController

package com.example.Config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.authentication.AuthenticationManager;
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.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.web.SecurityFilterChain;
import org.springframework.stereotype.Controller;


@Configuration
@EnableWebSecurity
public class SecurityConfig  {
    @Bean
    public SecurityFilterChain filterChain(HttpSecurity http,AuthenticationManagerBuilder auth) throws Exception {

        
        http.authorizeRequests()
                .antMatchers("/").permitAll()
                .antMatchers("/level1
        http.formLogin();
        return http.build();
    }

   

}
