springSecurity简单直接说明

引入依赖

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-security</artifactId>
        </dependency>
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
        </dependency>
         <!-- fastjson依赖 -->
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>fastjson</artifactId>
            <version>1.2.76</version>
        </dependency>

1，编辑实体类 用力存储用户数据

package com.mydemo.springbootdocker.domain;

import com.fasterxml.jackson.annotation.JsonIgnore;
import lombok.Data;

import java.io.Serializable;
import java.util.Date;

/**
 * 用户对象 sys_user
 *
 * @author deka
 */
@Data
public class SysUser implements Serializable {
    private static final long serialVersionUID = 1L;


    private String token;
    /**
     * 订单类型
     */
    private String orderType;

    /**
     * 用户ID
     */
    private Long userId;

    /**
     * 部门ID
     */
    private Long deptId;

    /**
     * 客户名称
     */
    private String customerName;

    private String customerUuid;

    /**
     * 所属区域
     */
    private String userRegion;

    /**
     * 用户账号
     */
    private String userName;

    /**
     * 用户昵称
     */
    private String nickName;

    /**
     * 用户身份
     */
    private String userIdentity;

    /**
     * 用户类别
     */
    private String userType;

    /**
     * 用户邮箱
     */
    private String email;

    /**
     * 手机号码
     */
    private String phonenumber;

    /**
     * 用户性别
     */
    private String sex;

    /**
     * 用户头像
     */
    private String avatar;

    /**
     * 密码
     */
    private String password;

    /**
     * 盐加密
     */
    private String salt;

    /**
     * 帐号状态（0正常 1停用）
     */
    private String status;

    /**
     * 删除标志（0代表存在 2代表删除）
     */
    private String delFlag;

    /**
     * 最后登录IP
     */
    private String loginIp;

    /**
     * 最后登录时间
     */
    private Date loginDate;


    /**
     * 角色组
     */
    private Long[] roleIds;

    /**
     * 岗位组
     */
    private Long[] postIds;

    /**
     * 所属客户UUID
     */
    private String[] customerUuids;

    /**
     * 所属区域
     */
    private String[] userRegions;

    /**
     * 是否工厂人员标志，0：否，1：是
     */
    private String isFactoryWorker;

    /**
     * 是否设备授权用户，0：否，1：是
     */
    private String isDeviceAuthUser;

    /**
     * 部门名称
     */
    private String deptName;

    /**
     * 审批名称
     */
    private String examine;

    /**
     * 核准名称
     */
    private String approval;

    /**
     * 机构层级
     */
    private Integer organizationLevel;
    @JsonIgnore
    private Integer parentOrganizationLevel;

    private String organizationId;
}

2，编辑 LoginUser 实现 UserDetails

package com.mydemo.springbootdocker.domain;

import lombok.Data;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;

import java.util.Collection;
import java.util.List;

/**
 * @Author wyt
 * @Date 2024/4/23 上午 10:34
 * @Version 1.0
 */
@Data
public class LoginUser implements UserDetails {

    public SysUser user;

    private  List<GrantedAuthority> auth;
    public LoginUser(SysUser sysUser,List<GrantedAuthority> auth) {
        this.user = sysUser;
        this.auth=auth;
    }

    @Override
    public Collection<? extends GrantedAuthority> getAuthorities() {
        return auth;
    }

    @Override
    public String getPassword() {
        return user.getPassword();
    }

    @Override
    public String getUsername() {
        return user.getUserName();
    }

    @Override
    public boolean isAccountNonExpired() {
        return true;
    }

    @Override
    public boolean isAccountNonLocked() {
        return true;
    }

    @Override
    public boolean isCredentialsNonExpired() {
        return true;
    }

    @Override
    public boolean isEnabled() {
        return true;
    }
}

3， 创建UserDetailsServiceImpl 类实现 接口UserDetailsService

package com.mydemo.springbootdocker.security;

import com.mydemo.springbootdocker.domain.LoginUser;
import com.mydemo.springbootdocker.domain.SysUser;
import lombok.extern.slf4j.Slf4j;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.AuthorityUtils;
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.core.userdetails.UsernameNotFoundException;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;

import java.util.List;

/**
 * @Author wyt
 * @Date 2024/4/23 上午 10:29
 * @Version 1.0
 */
@Slf4j
@Configuration
public class UserDetailsServiceImpl implements UserDetailsService {
    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        log.info("username= {}", username);
        /**
         * 实际操作，是根据用户输入的用户名，从数据库中获取用户名，密码 权限相关  然后加入到内存中
         * 后续操作是 使用数据库中存的加密数据，与用户输入的密码加密比较，看是否一直，如果一致表示认证成功，否则失败
         *
         * 本示例写死即可
         */

        SysUser sysUser = new SysUser();
        sysUser.setUserId(Long.valueOf(123));
        sysUser.setUserName(username);
        sysUser.setNickName("系统管理员");
        BCryptPasswordEncoder passwordEncoder = new BCryptPasswordEncoder();
        String encode = passwordEncoder.encode("123456");

        sysUser.setPassword(encode);
        //这里的角色信息没有从数据库里查询。实际开发中要从数据库里查询
        List<GrantedAuthority> auths = AuthorityUtils.commaSeparatedStringToAuthorityList("admin");
//        return new User(username,encode,auths);
        return createLoginUser(sysUser, auths);
    }

    public UserDetails createLoginUser(SysUser sysUser, List<GrantedAuthority> auths) {
        return new LoginUser(sysUser, auths);
    }
}

4，编辑SecurityWebConfig 类继承 WebSecurityConfigurerAdapter 类

package com.mydemo.springbootdocker.security;

import com.mydemo.springbootdocker.security.handler.LoginFailureHandler;
import com.mydemo.springbootdocker.security.handler.LoginSuccessHandler;
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.EnableWebSecurity;
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;

/**
 * @Author wyt
 * @Date 2024/4/23 下午 1:22
 * @Version 1.0
 */
@Configuration
@EnableWebSecurity
public class SecurityWebConfig extends WebSecurityConfigurerAdapter {


    @Autowired
    private UserDetailsService userDetailsService;


    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }

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

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .formLogin()
//                .loginProcessingUrl("/loginDeal")
                .usernameParameter("userName") // 提交表单中的用户名
                .passwordParameter("password") // 提交表单中的密码字段
//                .successHandler(new LoginSuccessHandler()) // 认证成功处理
//                .failureHandler(new LoginFailureHandler()) // 认证失败
                .permitAll()
                .and().authorizeRequests()
                .antMatchers("/test/**").permitAll() // 不需要登陆访问
                .anyRequest().authenticated()
                .and().csrf().disable() // 关闭csrf认证
        ;
    }

}

完成如上工作就可以访问测试了
并且congroller 中/test/… 下面的接口是不需要登陆认证的
