Spring-mvc + Spring-Security + Thymeleaf - 错误解决模板

Question

我正在学习构建 Spring + Spring Security + Thymeleaf + Maven 项目的简单在线教程，但出现以下错误：

看起来由于某种原因它没有解析登录页面，但即使登录页面位于正确的位置。 如果我指向该页面加载的 users.html 页面并且没有错误。 一定是我错过的非常简单的东西。 有人可以帮忙吗？

以下是我的配置类：

public class ApplicationInitializer implements WebApplicationInitializer {

@Override
public void onStartup(ServletContext servletContext) throws ServletException {
    //Load application context
    AnnotationConfigWebApplicationContext rootContext = new AnnotationConfigWebApplicationContext();
    rootContext.register(ApplicationContext.class);
    rootContext.setDisplayName("hub");

    //Context loader listener 
    servletContext.addListener(new ContextLoaderListener(rootContext));

    //Dispatcher servlet
    ServletRegistration.Dynamic dispatcher = 
            servletContext.addServlet("dispatcher", new DispatcherServlet(rootContext));
    dispatcher.setLoadOnStartup(1); 
    dispatcher.addMapping("/");
}

}

应用上下文类：

@Configuration 
@ComponentScan(basePackages = {"com.motodoc.hub.*"})
@EnableWebMvc
@Import({SpringDataConfig.class, ThymeleafConfig.class, SecurityConfig.class})
@ImportResource("classpath:trace-context.xml")
@PropertySource("classpath:spring.properties")
public class ApplicationContext extends WebMvcConfigurerAdapter {

// Maps resources path to webapp/resources
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
    registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
}

// Only needed if we are using @Value and ${...} when referencing properties
@Bean
public static PropertySourcesPlaceholderConfigurer properties() {
    PropertySourcesPlaceholderConfigurer propertySources = new PropertySourcesPlaceholderConfigurer();
    Resource[] resources = new ClassPathResource[] { 
            new ClassPathResource("spring.properties") };
    propertySources.setLocations(resources);
    propertySources.setIgnoreUnresolvablePlaceholders(true);
    return propertySources;
}

// Provides internationalization of messages
@Bean
public ResourceBundleMessageSource messageSource() {
    ResourceBundleMessageSource source = new ResourceBundleMessageSource();
    source.setBasename("messages");
    return source;
}
}

ThymeleafConfig 类：

@Configuration 
public class ThymeleafConfig {

@Bean 
public ServletContextTemplateResolver templateResolver() {
    ServletContextTemplateResolver resolver = new ServletContextTemplateResolver();
    resolver.setPrefix("/WEB-INF/views/");
    resolver.setSuffix(".html");
    resolver.setTemplateMode("HTML5");
    resolver.setOrder(1);
    return resolver;
}

@Bean 
public SpringTemplateEngine templateEngine() {
    SpringTemplateEngine engine = new SpringTemplateEngine();
    engine.setTemplateResolver(templateResolver());
    return engine;
}

@Bean 
public ThymeleafViewResolver thymeleafViewResolver() {
    ThymeleafViewResolver resolver = new ThymeleafViewResolver();
    resolver.setTemplateEngine(templateEngine());
    return resolver;
}   
}

SpringSecurityConfig 类：

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
  auth.inMemoryAuthentication().withUser("mkyong").password("123456").roles("USER");
  auth.inMemoryAuthentication().withUser("admin").password("123456").roles("ADMIN");
  auth.inMemoryAuthentication().withUser("dba").password("123456").roles("DBA");
}

@Override
public void configure(WebSecurity web) throws Exception {
    web.ignoring().antMatchers("/resources/**");
  }

@Override
protected void configure( HttpSecurity http ) throws Exception
{
    http
        .authorizeRequests()
        .antMatchers("/**").authenticated()
        .antMatchers("/resources/**").permitAll()
        .anyRequest().authenticated()
        .and()
    .formLogin()
        .loginPage("/login")
        .permitAll()
        .defaultSuccessUrl("/users")
        //.failureUrl("/login.html?authfailed=true")
        .and()
    .logout()
        .invalidateHttpSession(true)
        .logoutUrl("/logout")
        .deleteCookies("JSESSIONID")
        .logoutSuccessUrl("/");
}
}

安全初始化类：

public class SecurityInit extends AbstractSecurityWebApplicationInitializer {

}

Answer 1

可能你和 thymeleaf 和 springSecurity 的解析器有冲突。 您已将 loginPage 配置设置为“login”，而 thymeleaf 期待“login.html”。 您是否尝试将 .loginPage("/login") 更改为 .loginPage("/login.html") ？

Answer 2

只需从配置中删除后缀代码即可。

resolver.setSuffix(".html");

Answer 3

在 ThymeleafProperties 类中，视图的默认前缀是classpath:/templates/ ，默认后缀是.html 。 因此，将您的html更改为src/main/resources/templates/login.html ，如下图所示
