java - 独立运行 spring boot 应用程序时映射不起作用

Question

我在我的项目中使用了spring boot。当我使用 ide 启动应用程序时一切正常，但是当我运行 jar 文件并在浏览器中打开第一页时，我看到以下文本:

Whitelabel Error Page

This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Not Found, status=404).
/login.html

Spring Boot 配置类是:

@EnableAutoConfiguration
@EnableTransactionManagement
@EnableJpaAuditing
@EnableCaching
@EnableWebMvc
@EnableWebMvcSecurity
@Import({SecurityLauncher.class})
@EnableGlobalMethodSecurity(securedEnabled = true, prePostEnabled = true)
public class Launcher extends WebMvcConfigurerAdapter {

    public static void main(String[] args) {
        SpringApplication.run(Launcher.class);
    }

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        super.addResourceHandlers(registry);
    }

    @Bean
    public DispatcherServlet dispatcherServlet() {
        return new DispatcherServlet();
    }

    @Override
    public void configureDefaultServletHandling(
            DefaultServletHandlerConfigurer configurer) {
        configurer.enable();
    }
}

如何解决这个问题？

编辑 2 -> Spring 安全配置:

public class SecurityLauncher extends WebSecurityConfigurerAdapter {


    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests().antMatchers("/login/*", "/login.html*").permitAll().antMatchers("/*").authenticated()
                .and().formLogin().loginProcessingUrl("/login").loginPage("/login.html")
                .passwordParameter("password").usernameParameter("username").defaultSuccessUrl("/").and()
                .logout().logoutUrl("/logout").deleteCookies("JSESSIONID").permitAll().and().csrf().disable();
    }

    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth, UserSecurityProvider securityProvider) throws Exception {
        auth.userDetailsService(securityProvider);
    }

}

Answer 1

@SpringBootApplication 正在错误包中扫描 Controller ，但没有找到 Controller ，因此您必须删除@SpringBootApplication 并让@ComponentScan(basePackages = "...") 查找 Controller 以正确扫描。当您启动 login.html 时，您是否在日志中看到映射消息？
