Spring Security 5：找不到 BCryptPasswordEncoder 類型的 Beans

[英]Spring Security 5 : No Beans of type BCryptPasswordEncoder found

 原文  2018-03-05 17:45:55  4   6    java/ spring/ spring-boot/ spring-security

問題描述

我正在嘗試使用 JWT 令牌保護 REST API。 為了保存編碼的用戶密碼，我正在嘗試使用 bcrypt 進行編碼。 但是，當我嘗試自動裝配 BCryptPasswordEncoder 時，出現以下錯誤：

Could not autowire. No beans of BCryptPasswordEncoder type found. Check autowiring problems in bean class.

這是我的控制器的樣子：

package com.starter.springsecurity.demo.controller;

import com.starter.springsecurity.demo.domain.User;
import com.starter.springsecurity.demo.repository.UserRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/users")
public class UserController {

    @Autowired
    private UserRepository userRepository;

    private BCryptPasswordEncoder bCryptPasswordEncoder;

    public UserController(BCryptPasswordEncoder bCryptPasswordEncoder){
        this.bCryptPasswordEncoder = bCryptPasswordEncoder;
    }

    @RequestMapping("/register")
    public void register(@RequestBody User user){

    }
}

@Bean

這段代碼通過將它放置在spring的主類（Spring5MvcRestApplication）中對我有用

您剛剛在代碼或主類中添加了 BCryptPasswordEncoder：

@Bean
public BCryptPasswordEncoder bCryptPasswordEncoder() {
