java - 创建名称为authenticationTokenFilterBean 的bean 时出错 : Unsatisfied dependency expressed through field tokenUtils

Question

我想在我的项目中实现Spring Security。但无论我尝试什么，我都会遇到同样的错误。

我创建了必要的类(TokenUtils、AuthenticationTokenFilter、SpringConfiguration)。它们位于同一包下，但我收到以下错误。

这是我的堆栈跟踪发生问题的部分

Description:

   Field tokenUtils in      com.sbvtransport.sbvtransport.security.AuthenticationTokenFilter required a bean of type 'com.sbvtransport.sbvtransport.security.TokenUtils' 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.sbvtransport.sbvtransport.security.TokenUtils' in your configuration.    
package com.sbvtransport.sbvtransport.security;

这些是我的安全类(class):

AuthenticationTokenFilter

import java.io.IOException;

import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter;
import org.springframework.security.web.authentication.WebAuthenticationDetailsSource;

public class AuthenticationTokenFilter  extends UsernamePasswordAuthenticationFilter{

@Autowired
TokenUtils tokenUtils;

@Autowired
private UserDetailsService userDetailsService;

@Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
        throws IOException, ServletException {
    HttpServletRequest httpRequest = (HttpServletRequest) request;
    String authToken = httpRequest.getHeader("Authorization");
    String username = tokenUtils.getUsernameFromToken(authToken);

    if (username != null && SecurityContextHolder.getContext().getAuthentication() == null) {
        UserDetails userDetails = this.userDetailsService.loadUserByUsername(username);
        if (tokenUtils.validateToken(authToken, userDetails)) {
            UsernamePasswordAuthenticationToken authentication = new UsernamePasswordAuthenticationToken(
                    userDetails, null, userDetails.getAuthorities());
            authentication.setDetails(new WebAuthenticationDetailsSource().buildDetails(httpRequest));
            SecurityContextHolder.getContext().setAuthentication(authentication);
        }
    }

    chain.doFilter(request, response);
}

}

TokenUtils

package com.sbvtransport.sbvtransport.security;

import java.util.Date;
import java.util.HashMap;
import java.util.Map;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.security.core.userdetails.UserDetails;

import io.jsonwebtoken.Jwts;
import io.jsonwebtoken.SignatureAlgorithm;

public class TokenUtils {

@Value("SuperSecreat")
private String secret;

@Value("86400") // 24 hours(in seconds)
private Long expiration;

public String getUsernameFromToken(String token) {
    String username;
    try {
        Claims claims = this.getClaimsFromToken(token);
        username = claims.getSubject();
    } catch (Exception e) {
        username = null;
    }
    return username;
}

private Claims getClaimsFromToken(String token) {
    Claims claims;
    try {
        claims = Jwts.parser().setSigningKey(this.secret).parseClaimsJws(token).getBody();
    } catch (Exception e) {
        claims = null;
    }
    return claims;
}

public Date getExpirationDateFromToken(String token) {
    Date expirationDate;
    try {
        final Claims claims = this.getClaimsFromToken(token);
        expirationDate = claims.getExpiration();
    } catch (Exception e) {
        expirationDate = null;
    }
    return expirationDate;
}

private boolean isTokenExpired(String token) {
    final Date expirationDate = this.getExpirationDateFromToken(token);
    return expirationDate.before(new Date(System.currentTimeMillis()));
}

public boolean validateToken(String token, UserDetails userDetails) {
    final String username = getUsernameFromToken(token);
    return username.equals(userDetails.getUsername()) && !isTokenExpired(token);
}

public String generateToken(UserDetails userDetails) {
    Map<String, Object> claims = new HashMap<String, Object>();
    claims.put("sub", userDetails.getUsername());
    claims.put("created", new Date(System.currentTimeMillis()));
    return Jwts.builder().setClaims(claims).setExpiration(new Date(System.currentTimeMillis() + expiration * 1000))
            .signWith(SignatureAlgorithm.HS512, secret).compact();
}

}

安全配置

package com.sbvtransport.sbvtransport.security;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.authentication.AuthenticationManager;
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.crypto.password.PasswordEncoder;
import org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter;

@SpringBootApplication
@Configuration
@EnableWebSecurity
@EnableAutoConfiguration
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
@Autowired
private UserDetailsService userDetailsService;

@Autowired
public void configureAuthentication(AuthenticationManagerBuilder authenticationManagerBuilder) throws Exception {

    authenticationManagerBuilder.userDetailsService(this.userDetailsService).passwordEncoder(passwordEncoder());
}

@Bean
public PasswordEncoder passwordEncoder() {
    return new BCryptPasswordEncoder();
}

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

@Bean
public AuthenticationTokenFilter authenticationTokenFilterBean() throws Exception {
    AuthenticationTokenFilter authenticationTokenFilter = new AuthenticationTokenFilter();
    authenticationTokenFilter.setAuthenticationManager(authenticationManagerBean());
    return authenticationTokenFilter;
}

@Override
protected void configure(HttpSecurity httpSecurity) throws Exception {
    httpSecurity.csrf().disable().sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS).and()
            .authorizeRequests().antMatchers("").permitAll();

    httpSecurity.addFilterBefore(authenticationTokenFilterBean(), UsernamePasswordAuthenticationFilter.class);
}

  }

似乎 AuthenticationTokenFilter 内的 Autowiring TokenUtils 有问题，但我也可能是错的。

我希望我的问题足够清楚，如果我可以做任何改进，请提出建议。

错误:错误消息清楚地表明未找到TokenUtils bean

'com.sbvtransport.sbvtransport.security.TokenUtils' that could not be found.

您在 TokenUtils 上缺少 @Component，使用 @Component 声明类会使组件扫描在应用程序上下文中创建此类的单例 bean

@Component
public class TokenUtils {

以及AuthenticationTokenFilter上的@Configuration

@Configuration
public class AuthenticationTokenFilter  extends UsernamePasswordAuthenticationFilter{

@SpringBootApplication 在其声明的包中启用组件扫描

@EnableAutoConfiguration: enable Spring Boot’s auto-configuration mechanism

@ComponentScan: enable @Component scan on the package where the application is located (see the best practices)

@Configuration: allow to register extra beans in the context or import additional configuration classes

The @SpringBootApplication annotation is equivalent to using @Configuration, @EnableAutoConfiguration, and @ComponentScan with their default attributes,
