Java Field authenticationManager LoginController需要一个类型为authenticationManager'；那是找不到的

尝试使用spring security设置我的SecurityConfigure时出现此错误

APPLICATION FAILED TO START

Description:

Field authenticationManager in com.springvuegradle.Controller.LoginController required a bean of type 'org.springframework.security.authentication.AuthenticationManager' that could not be found.

The injection point has the following annotations:
        - @org.springframework.beans.factory.annotation.Autowired(required=true)


Action:

Consider defining a bean of type 'org.springframework.security.authentication.AuthenticationManager' in your configuration.

正如其他答案所建议的那样，我已经覆盖了authenticationManagerBean，但是这没有帮助。欢迎任何意见。下面是我的SecurityConfigure类

package com.springvuegradle.Security;

import com.springvuegradle.Services.MyUserDetailsService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.crypto.password.NoOpPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;

public class SecurityConfigurer extends WebSecurityConfigurerAdapter {

    @Autowired
    private MyUserDetailsService myUserDetailsService;

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(myUserDetailsService);
    }

    /***
     * Requires authentication for all endpoints except the /authenticate endpoint.
     */
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests().antMatchers("/authenticate").permitAll().anyRequest().authenticated();
    }

    @Override
    @Bean
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }

    @Bean
    public PasswordEncoder passwordEncoder(){
        //TODO change this to actually hash the password
        return NoOpPasswordEncoder.getInstance();
    }
}

登录控制器

@RestController
public class LoginController {

    @Autowired
    private AuthenticationManager authenticationManager;

查看代码，似乎您正在尝试在LoginController中自动连接SecurityConfigure。但是在SpringSecurity中，不需要自动连接configurer类。另外，正如您所提到的，重写authenticationManagerBean只会为您提供AuthenticationManager类型的bean，而不是SecurityConfigurer类型的bean。

您好，谢谢您的回复。我相信我只是想在我的LoginController中自动连接一个AuthenticationManager bean。我已将相关代码添加到我的原始帖子中。您似乎忘记在SecurityConfigure类上添加@EnableWebSecurity注释。即使添加了配置和@EnableWebSecurity注释，错误仍然存在。您认为这可能是项目配置的问题吗？应用@EnableWebSecurity注释后，情况不应该如此。我尝试了同样的代码，它对我很有效。它将能够找到AuthenticationManager bean，并且完全可以自动连接。
