Java BCrypt+；弹簧靴

我使用此控制器创建用户：

@PostMapping
public ResponseEntity<?> insert(@Valid @RequestBody UserDTO userDTO,
        UriComponentsBuilder uriInfo) {

    User user = UserDTO.getEntity(userDTO);
    final Long id = service.insert(user);

    final URI location = ServletUriComponentsBuilder.fromCurrentRequest().path("/{id}").buildAndExpand(id).toUri();

    return ResponseEntity.created(location).build();

}

我提供了一项服务，该服务可以接收该用户并将密码更改为加密密码：

public Long insert(User user) {
        user.setPassword(PasswordUtils.generateBCrypt(user.getPassword()));
        repository.save(user);
        return user.getId();
    }

PasswordUtils.class的代码如下：

import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;

public class PasswordUtils {

    public static String generateBCrypt(String password) {

        if (password == null) {
            return password;
        }

        BCryptPasswordEncoder encoder = new BCryptPasswordEncoder();
        return encoder.encode(password);

    }

}

在我的pom.xml中，我对spring boot starter安全性依赖项进行了注释，因为当我不进行注释时，它会要求我输入用户名和密码以发出请求。调用REST服务时出现错误：java.lang.ClassNotFoundException错误：org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder

如何在没有我的服务的情况下使用BCrypt询问凭据

可能重复FWIW，没有理由每次都创建一个新编码器。将其设为常量或注入一个公共实例。@chrylis，即使注入，错误仍然存在。我对这种方法不是很确定。尝试为

BCryptPasswordEncoder

创建bean，并对其进行自动布线。也许是个坏主意
