spring data r2dbc 通过 Entity Callbacks 来实现密码加密功能

不使用使用 Entity Callbacks实现密码在保存时密码加密功能

 @Autowired
 PasswordEncoder passwordEncoder;

public Mono<ServerResponse> save(ServerRequest request){
       return request.bodyToMono(Doctor.class)
               .map(d -> {
                   d.setIsVerified(false);
                   d.setPassword(passwordEncoder.encode(d.getPassword()));
                   return d;
               })
               .flatMap(doctor -> doctorService.saveDoctor(doctor))
               .flatMap(d -> ServerResponse.created(URI.create("/doctors/" + d.getId())).bodyValue(d));
}

使用 Entity Callbacks功能实现密码加密

• 定义一个回调类实现BeforeSaveCallback

import com.fengyun.medical.domain.Doctor;
import org.reactivestreams.Publisher;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.r2dbc.mapping.OutboundRow;
import org.springframework.data.r2dbc.mapping.event.BeforeSaveCallback;
import org.springframework.data.relational.core.sql.SqlIdentifier;
import org.springframework.r2dbc.core.Parameter;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.stereotype.Component;
import reactor.core.publisher.Mono;

@Component
public class MedicalCallBack implements BeforeSaveCallback<Doctor> {

    @Autowired
    PasswordEncoder passwordEncoder;

    @Override
    public Publisher<Doctor> onBeforeSave(Doctor entity, OutboundRow row, SqlIdentifier table) {
        row.put("is_verified", Parameter.from(false));
        row.put("password",Parameter.from(passwordEncoder.encode(entity.getPassword())));
        return Mono.just(entity);
    }
}

• handler处理流程

  public Mono<ServerResponse> save(ServerRequest request){
       return request.bodyToMono(Doctor.class)
               .flatMap(doctor -> doctorService.saveDoctor(doctor))
               .flatMap(d -> ServerResponse.created(URI.create("/doctors/" + d.getId())).bodyValue(d));

    }
