我正在 youtube 教程中处理该项目并陷入此异常。如何解决 org.springframework.beans.factory.BeanCreationNotAllowedException?
我正在 youtube 教程中处理该项目,但遇到了此异常。我在 Stack Overflow 上看到过类似的问题,但有一个不正确的导入问题。我已经检查了我的导入,没有问题。我试图将此文件移动到 root,但我再次遇到了同样的错误。我曾尝试在 youtube 和网络上找到解决方案,但我没有得到任何软件。请帮我找出解决办法。

Description:
Field userSecurityService in com.bookstore.config.SecurityConfig required a bean of type 'com.bookstore.service.impl.UserSecurityService' 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 'com.bookstore.service.impl.UserSecurityService' in your configuration.
UserSecurityService.java
package com.bookstore.service.impl;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import com.bookstore.domain.User;
import com.bookstore.repository.UserRepository;
public class UserSecurityService implements UserDetailsService {
@Autowired
private UserRepository userRepository;
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
User user=userRepository.findByUsername(username);
if(null == user) {
throw new UsernameNotFoundException("Username Not Found");
}
return user;
}
}
package com.bookstore.config;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.env.Environment;
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.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.web.util.matcher.AntPathRequestMatcher;
import com.bookstore.service.impl.UserSecurityService;
import com.bookstore.utility.SecurityUtility;
@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
@ComponentScan("com.bookstore.service.impl.UserSecurityService")
public class SecurityConfig extends WebSecurityConfigurerAdapter{
@Autowired
private Environment env;
@Autowired
private UserSecurityService userSecurityService;
private BCryptPasswordEncoder passwordEncoder() {
return SecurityUtility.passwordEncoder();
}
private static final String[] PUBLIC_MATCHERS = {
"/css/**","/js/**","/image/**","/","/myAccount"
};
@Override
protected void configure(HttpSecurity http) throws Exception{
http
.authorizeRequests().
/*antMatchers("/**").*/
antMatchers(PUBLIC_MATCHERS).
permitAll().anyRequest().authenticated();
http
.csrf().disable().cors().disable()
.formLogin().failureUrl("/login?error").defaultSuccessUrl("/")
.loginPage("/login").permitAll()
.and()
.logout().logoutRequestMatcher(new AntPathRequestMatcher("/logout"))
.logoutSuccessUrl("/?logout").deleteCookies("remember-me").permitAll()
.and()
.rememberMe();
}
@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth)
throws Exception{
auth.userDetailsService(userSecurityService).passwordEncoder(passwordEncoder());
}
}
解决方法
您需要在 @Service
上添加 UserSecurityService
,如下所示。
@Service
public class UserSecurityService implements UserDetailsService {
@Autowired
private UserRepository userRepository;
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
User user=userRepository.findByUsername(username);
if(null == user) {
throw new UsernameNotFoundException("Username Not Found");
}
return user;
}
}
