我正在遵循这个auth0的教程来使用JWT来保护我的应用程序.

我最终得到了以下WebSecurity配置:

@EnableWebSecurity
@AllArgsConstructor(onConstructor = @__(@Autowired))
public class WebSecurity extends WebSecurityConfigurerAdapter {

    private final UserDetailsService userDetailsService;
    private final BCryptPasswordEncoder passwordEncoder;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.formLogin()
                .and().cors()
                .and().csrf()
                .disable()
                .authorizeRequests()
                .antMatchers(HttpMethod.POST, REGISTER_URL).permitAll()
                .antMatchers(HttpMethod.POST, LOGIN_URL).permitAll()
                .anyRequest().authenticated()
                .and()
                .addFilter(new JWTAuthorizationFilter(authenticationManager()))
                .addFilter(new JWTAuthenticationFilter(authenticationManager()))
                // This disables session creation on Spring Security
                .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);
    }

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

    @Bean
    public CorsConfigurationSource corsConfigurationSource() {
        final UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", new CorsConfiguration().applyPermitDefaultValues());
        return …

我有如下数据类：

@Entity
@Table(name = "SECTIONS")
data class Section(

        @Id @GeneratedValue
        @Column(name = "ID")
        var id: Long = 0,

        @Column(name = "NAME")
        var name: String = "",

        @OneToMany(
                mappedBy = "section",
                fetch = FetchType.EAGER,
                cascade = arrayOf(CascadeType.ALL),
                orphanRemoval = true
        )
        var fields: MutableList<Field> = mutableListOf()
)

@Entity
@Table(name = "FIELDS")
data class Field(

        @Id @GeneratedValue
        @Column(name = "ID")
        var id: Long = 0,

        @Column(name = "NAME")
        var name: String = "",

        @ManyToOne
        @JoinColumn(name = "SECTION_ID")
        var section: Section? = null …

我有一个 Spring @Configuration 类，如下所示：

@Configuration
public class ExecutorServiceConfiguration {

    @Bean
    public BlockingQueue<Runnable> queue() {
        return ArrayBlockingQueue<>(1000);
    }     

    @Bean
    public ExecutorService executor(BlockingQueue<Runnable> queue) {
        return ThreadPoolExecutor(1, 1, 0L, TimeUnit.MILLISECONDS, queue);
    }

    @PreDestroy
    public void shutdownExecutor() {
        // no executor instance
    }
}

我还想指定一种@PreDestroy关闭 ExecutorService 的方法。但是，该@PreDestroy方法不能有任何参数，这就是为什么我无法将executorbean 传递给该方法以关闭它的原因。指定 destroy 方法也@Bean(destroyMethod = "...")不起作用。它允许我指定现有的shutdownor shutdownNow，但不能指定我打算使用的自定义方法。

我知道我可以直接实例化队列和执行器，而不是作为 Spring bean，但我宁愿这样做。
