SpringSecurity报错authenticationManager must be spec的解决

在重写类UsernamePasswordAuthenticationFilter时抛出了这个异常，字面上理解是authenticationManager不明确，所以要显示的注入。

有两个地方要改下

首先要在配置文件重写authenticationManager

@Bean
   @Override
   protected AuthenticationManager authenticationManager() throws Exception {
       return super.authenticationManager();
   }

然后在过滤器里面显示的设置一下

@Autowired
   @Override
   public void setAuthenticationManager(AuthenticationManager authenticationManager) {
       super.setAuthenticationManager(authenticationManager);
   }

顺便贴一下两个类的完整代码

仅供参考：

过滤器

@Component
public class TokenLoginFilter extends UsernamePasswordAuthenticationFilter {
   @Autowired
   JwtTokenUtils jwtTokenUtils;

public TokenLoginFilter() {
       this.setPostOnly(false);
       this.setRequiresAuthenticationRequestMatcher(new AntPathRequestMatcher("/login","POST"));
   }

@Override
   public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response) throws AuthenticationException {
       //获取表单提交数据
       try {
           UserInfo user = new ObjectMapper().readValue(request.getInputStream(), UserInfo.class);
           return super.getAuthenticationManager().authenticate(new UsernamePasswordAuthenticationToken(user.getLoginName(),user.getPassword(),
                   new ArrayList<>()));
       } catch (IOException e) {
           e.printStackTrace();
           throw new RuntimeException();
       }
   }

@Override
   protected void successfulAuthentication(HttpServletRequest request, HttpServletResponse response, FilterChain chain, Authentication authResult) throws IOException, ServletException {
       UserSecurity userSecurity = (UserSecurity) authResult.getPrincipal();
       String token = jwtTokenUtils.createToken(userSecurity.getUsername());
       ResponseUtils.out(response, R.ok(token));
   }

@Override
   protected void unsuccessfulAuthentication(HttpServletRequest request, HttpServletResponse response, AuthenticationException failed) throws IOException, ServletException {
       ResponseUtils.out(response, R.fail(ServiceError.LOGIN_FAIL));
   }

@Autowired
   @Override
   public void setAuthenticationManager(AuthenticationManager authenticationManager) {
       super.setAuthenticationManager(authenticationManager);
   }
}

配置文件

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {

@Autowired
   UserInfoServiceImpl userInfoService;

@Autowired
   JwtAuthorizationTokenFilter jwtAuthorizationTokenFilter;

@Autowired
   TokenLoginFilter tokenLoginFilter;

@Autowired
   JwtAuthenticationEntryPoint jwtAuthenticationEntryPoint;

@Autowired
   public void configure(AuthenticationManagerBuilder auth) throws Exception {
       auth.userDetailsService(userInfoService).passwordEncoder(passwordEncoderBean());
   }

@Override
   protected void configure(HttpSecurity http) throws Exception {
       http.exceptionHandling()
               .authenticationEntryPoint(jwtAuthenticationEntryPoint)
               .and().csrf().disable()
               .authorizeRequests()
               .antMatchers("/login").permitAll()
               .antMatchers("/hello").permitAll()
               .antMatchers(HttpMethod.OPTIONS, "/**").anonymous()
               .anyRequest().authenticated()
               .and()
               .addFilterAt(tokenLoginFilter, UsernamePasswordAuthenticationFilter.class)
               .addFilterAfter(jwtAuthorizationTokenFilter, TokenLoginFilter.class).httpBasic();

}

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

@Bean
   @Override
   protected AuthenticationManager authenticationManager() throws Exception {
       return super.authenticationManager();
   }
}
