Empty encoded password warning reason

Premise ：

1. Use SpringSecurity Rights management framework .
2. Console prompts during login Empty encoded password.

Possible causes ：

3. Framework version conflict does not support .
4. The database password sub segment is stored in the database without encoding and encryption at the time of registration .
5. Incorrect use of entity class .

resolvent ：

6. Revised version .
7. When a new user is added to the database, the foreground password is encoded and stored in the database , The method is below .
8. Bear in mind , Login Class and implementation UserDetails The class of cannot be the same , Otherwise, the password will not be found . And inherit UserDetails In the class ,username and password Remember to return to the user in the database username and password.

Register encryption ：

	@Override
    public Res register(LoginBody loginBody) {
    
        String msg = "";
        SysUser sysUserDb = baseMapper.selectOne(Wrappers.<SysUser>lambdaQuery().eq(SysUser::getUserName, loginBody.getUserName()));
        if (sysUserDb != null) {
    
            msg = " Save the user '" + loginBody.getUserName() + "' Failure , The registered account already exists ";
        } else {
    
            SysUser sysUser = new SysUser();
            sysUser.setUserName(loginBody.getUserName());
            sysUser.setNickName(loginBody.getUserName());
            sysUser.setPassword(encryptPassword(loginBody.getPassword()));
            int regFlag = baseMapper.insert(sysUser);
            if (regFlag != 1) {
    
                msg = " Registration failed , Please contact the system administrator ";
            }
            return Res.ok(" Registered successfully ");
        }
        return Res.failed(msg);
    }

	/** *  Generate BCryptPasswordEncoder password  * * @param password  password  * @return  Encrypted string  */
    public static String encryptPassword(String password) {
    
        BCryptPasswordEncoder passwordEncoder = new BCryptPasswordEncoder();
        return passwordEncoder.encode(password);
    }

Entity class ：
Login entity class ：

package com.spring.security.entity;

import lombok.Data;

/** *  User login object  * * @author ruoyi */
@Data
public class LoginBody {
    
    /** *  user name  */
    private String userName;

    /** *  User password  */
    private String password;

    /** *  Verification Code  */
    private String code;

    /** *  Unique identification  */
    private String uuid;
}

Login return entity class ：
Be careful getUsername() and getPassword() Method
