我在运行此代码时出错,代码中有一个注入周期,但我找不到它。顺便说一句,我是新的Spring。我该如何解决这个问题?有什么好的文件吗?
这是我的代码;
WebSecurityConfiguration类:
软件包com.trendyol.app;

import com.trendyol.app.auth.JwtTokenFilter;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.config.http.SessionCreationPolicy;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter;

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled=true) //Tüm methodlarımızdan önce security devreye girer
public class WebSecurityConfiguration extends WebSecurityConfigurerAdapter {

    ///////////////////
    @Autowired
    private JwtTokenFilter jwtTokenFilter;

    @Autowired
    private UserDetailsService userDetailsService;

    @Autowired
    public void configurePasswordEncoder(AuthenticationManagerBuilder builder  ) throws Exception{
        builder.userDetailsService(userDetailsService).passwordEncoder(getBCryptPasswordEncoder());
    }
    ///////////////////
    @Bean
    public BCryptPasswordEncoder getBCryptPasswordEncoder(){
       return new BCryptPasswordEncoder();
    }

    @Bean
    public AuthenticationManager getAuthenticationManager() throws Exception{
        return super.authenticationManagerBean();
    }
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().disable()
                .authorizeRequests()
                .antMatchers("/login") //bu adress hariç
                .authenticated()
                .and()
                .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);

        http.addFilterBefore(jwtTokenFilter, UsernamePasswordAuthenticationFilter.class);

    }
}

字符串
UserDetailsService:

package com.trendyol.app.auth;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.userdetails.User;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.stereotype.Service;

import javax.annotation.PostConstruct;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.Map;

@Service
public class UserDetailsService implements org.springframework.security.core.userdetails.UserDetailsService {
    private Map<String,String > users=new HashMap<>();

    @Autowired
    private BCryptPasswordEncoder passwordEncoder;

    @PostConstruct
    public void init(){
        users.put("temelt", passwordEncoder.encode("123"));
    }

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        if(users.containsKey(username)){
            return new User(username,users.get(username),new ArrayList<>());
        }
        throw new UsernameNotFoundException(username);
    }
}

您是否尝试过使用@Lazy标记而不是@Autowired标记标记PasswordEncoder?从文档:
指示是否要延迟初始化bean。
我也遇到过类似的问题,改用@Lazy是我解决问题的一种方法。在你的例子中,它看起来像这样:

@Service
public class UserDetailsService implements org.springframework.security.core.userdetails.UserDetailsService {
    private Map<String,String > users=new HashMap<>();

    @Lazy
    private BCryptPasswordEncoder passwordEncoder;

    @PostConstruct
    public void init(){
