今天主要完成了jwt令牌对用户的加密，使得数据库系统的安全性得到了提升，

使用这个来对用户进行加密，使用

加密，在对象上加上

package com.example.greensage.entity;

import com.baomidou.mybatisplus.annotation.TableName;
import com.baomidou.mybatisplus.annotation.IdType;
import com.baomidou.mybatisplus.annotation.TableId;
import java.io.Serializable;
import java.util.Collection;
import java.util.List;

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

/**
 * <p>
 * 
 * </p>
 *
 * @author xue
 * @since 2024-04-19
 */
@Data
@EqualsAndHashCode(callSuper = false)
@Accessors(chain = true)
@TableName("_user")
public class User implements Serializable,UserDetails{

    private static final long serialVersionUID = 1L;

    @TableId(value = "id", type = IdType.AUTO)
    private Long id;

    private String username;

    private String nickname;

    private String password;

    private String role;

    private Integer points;

    @Override
    public String getPassword() {
        return "{noop}" + password;
    }

    @Override
    public Collection<? extends GrantedAuthority> getAuthorities() {
        return List.of((GrantedAuthority) () -> role);
    }

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

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

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

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

然后在请求时调用

 @GetMapping
    public ResponseEntity<?> getUserinfo(Authentication authentication) {
        return ResponseEntity.ok(authentication.getName());
    }

封装完成
