Spring mvc Spring安全登录不'；使用Bcrypt时无法工作

我使用SpringMVC和SpringSecurity创建了登录页面，所有功能都正常工作，但当为登录和注册添加加密时，它不起作用（用户密码也在数据库中加密）

security-config.xml

这里有什么问题

您似乎无法向身份验证提供商提供自己的bcrypt加密机。您需要将

BCryptPasswordEncoder

声明为Springbean，并将其自动连接到控制器，同时将其传递给身份验证提供者。请参阅下面的代码片段以供参考

spring security.xml

<authentication-manager>
    <authentication-provider>
        <password-encoder ref="encoder" />
        <!-- your jdbc user details service declaration --> 
    </authentication-provider>
</authentication-manager>

<beans:bean id="encoder" class="org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder">
    <beans:constructor-arg name="strength" value="11" />
</beans:bean>

你说不工作是什么意思？有错误吗？您是否尝试过将spring security package设置为调试并检查日志？在没有加密的情况下，它可以正常工作，但当使用加密密码添加新用户时，当我尝试登录@Setu时，它会给我错误的凭据

<authentication-manager>
    <authentication-provider>
        <password-encoder ref="encoder" />
        <!-- your jdbc user details service declaration --> 
    </authentication-provider>
</authentication-manager>

<beans:bean id="encoder" class="org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder">
    <beans:constructor-arg name="strength" value="11" />
</beans:bean>

@Autowired
private BCryptPasswordEncoder encoder;

@RequestMapping(value = "/signup", method = RequestMethod.POST)
public String postSignUpPage(@ModelAttribute User user ,@RequestParam("password") String password) {
    user.setPassword(encoder.encode(password));
    userRepo.save(user);
    return "redirect:/signin";
}
