Question

我下面爲構建春春+ +安全+ Thymeleaf Maven項目一個簡單的在線教程，我發現了以下錯誤：

由於某些原因，它不會解析登錄頁面，但即使登錄頁面位於正確的位置。如果我指向頁面加載的users.html頁面並且沒有錯誤。必須是非常簡單的東西，我錯過了。有人可以協助嗎？

以下是我的配置類：

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("/"); 
} 

} 

的ApplicationContext類：

@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類：

@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類：

@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("/"); 
} 
} 

SecurityInit類：

public class SecurityInit extends AbstractSecurityWebApplicationInitializer { 

} 

Answer 1

也許你有thymeleaf和springSecurity的解析器的衝突。您已將loginPage配置設置爲「登錄」，並且thymeleaf期待「login.html」。您是否嘗試更改.loginPage（「/ login.html」）的.loginPage（「/ login」）？

Answer 2

只需從配置中刪除後綴代碼即可。

resolver.setSuffix(".html"); 

Answer 3

在ThymeleafProperties類的意見則默認前綴爲classpath:/templates/，默認後綴爲.html。因此，改變你的html到src/main/resources/templates/login.html，如下面的圖像
