我正在尝试使用 JWT token 保护 REST API 的安全。为了保存编码的用户密码,我尝试使用 bcrypt 进行编码。但是,当我尝试 Autowiring BCryptPasswordEncoder 时,出现以下错误:
Could not autowire. No beans of BCryptPasswordEncoder type found. Check autowiring problems in bean class.
这就是我的 Controller 的样子:
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){
}
}
这是我正在关注的博客: https://dzone.com/articles/implementing-jwt-authentication-on-spring-boot-api

Spring Security 5 中有关 Bcrypt 的内容有变化吗?
最佳答案
您提到的文章对此进行了进一步描述:
There is no default instance of BCryptPasswordEncoder that can be injected in the UserController class
稍后在代码中
@Bean
public BCryptPasswordEncoder bCryptPasswordEncoder() {
return new BCryptPasswordEncoder();
}
您是否按照这些步骤操作并定义了 BCryptPasswordEncoder
类?
关于java - Spring 安全5 : No Beans of type BCryptPasswordEncoder found,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/49116485/
