spring-security 自定义登录页面

1.在配置类中实现相关的配置

package com.example.securitydemo.config;


import org.springframework.beans.factory.annotation.Autowired;
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.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;

import javax.annotation.Resource;

@Configuration
public class SecurityConfigTest extends WebSecurityConfigurerAdapter {

    @Resource
    private UserDetailsService myUserDetailsService;

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(myUserDetailsService).passwordEncoder(password());
    }

    @Bean
    PasswordEncoder password(){
        return new BCryptPasswordEncoder();
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.formLogin()  //自定义自己编写的登录页面
                .loginPage("login.html")//登录页面设置
                .loginProcessingUrl("/user/login")  //登录访问路径
                .defaultSuccessUrl("/test/index") //登录成功跳转路径
                .permitAll()
                .and().authorizeRequests()
                .antMatchers("/","/test/hello","/user/login").permitAll()//设置那些路径可以直接访问，不需要认证
                .anyRequest().authenticated()
                .and().csrf().disable(); //关闭csrf防护
    }
}
