Password Encoder Match not working Spring boot - spring

Question

i am creating the Spring Boot application login with hash password.without set hash password login working successfully.with hash password set getting error while writing the code.
passwordEncoder.matches(loginDTO.getEmail())
it indicate the error was
'matches(java.lang.CharSequence, java.lang.String)' in 'org.springframework.security.crypto.password.PasswordEncoder' cannot be applied to '(java.lang.String)'
what i tried so far i attached the full code below.
LoginDTO.java
package com.example.Registation.Dto;
public class LoginDTO {
private String email;
private String password;
public LoginDTO() {
}
public LoginDTO(String email, String password) {
this.email = email;
this.password = password;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
#Override
public String toString() {
return "LoginDTO{" +
"email='" + email + '\'' +
", password='" + password + '\'' +
'}';
}
}
EmployeeController.java
#PostMapping(path = "/login")
public String loginEmployee(#RequestBody LoginDTO loginDTO)
{
String email = employeeService.loginEmployee(loginDTO);
return email;
}
Employee Service
public interface EmployeeService {
String loginEmployee(LoginDTO loginDTO);
}
EmployeeRepo
#EnableJpaRepositories
#Repository
public interface EmployeeRepo extends JpaRepository<Employee,Integer>
{
Optional<Employee> findOneByEmailAndPassword(String email, String password);
}
EmployeeIMPL
#Override
public String loginEmployee(LoginDTO loginDTO) {
CharSequence password = loginDTO.getPassword();
String encodedPassword = loginDTO.getPassword(); // assume this is the encoded password from the database
Optional<Employee> employee = employeeRepo.findOneByEmailAndPassword(loginDTO.getEmail(), passwordEncoder.matches(password,encodedPassword));
if (employee.isPresent()) {
return "Login Success for " + employee.get();
} else {
return "Login Fail";
}
}
}

Answer 1

import org.springframework.security.crypto.password.PasswordEncoder;
//PasswordEncoder bean
#Autowired
private PasswordEncoder passwordEncoder;
//check password
if (passwordEncoder.matches(changePasswordRequest.getOldPassword(), user.getPassword())){
}
Both password type is String.
OldPassword and Password type is String.
