UndertowServer+SpringMVC+Thymeleaf模板引擎構建輕量級的web項目

這兩周需要寫一個頁面來請求另一個服務中的接口，服務器采用了超輕量級的undertow，模板引擎采用的是Thymeleaf，在尋找頁面資源位置這個地方難住了我。下面分享一下，這方面的代碼。

SpringWebConfig方面：

public class SpringWebConfig extends WebMvcConfigurerAdapter {
 private static boolean initialized = false;

 @Bean
 public static PropertySourcesPlaceholderConfigurer config() {
 return SpringConfigHelper.createPlaceholderConfigBean("classpath:prime.cfg");
 }

 /**
 * Spring容器初始化完成后回調該函數
 * 通過該機制可以動態擴展bean實例配置
 * 用於工作服務框架加載工作服務實現相關bean
 *
 * @param basePackage 擴展bean掃描路徑
 * @return ApplicationListener實例
 */
 @Bean
 public ApplicationListener<ContextRefreshedEvent> initializedEvent(
 @Value("${Optimus.Prime.ServiceBasePackage:}") String basePackage) {
 return new ApplicationListener<ContextRefreshedEvent>() {
 @Override
 public void onApplicationEvent(ContextRefreshedEvent event) {
 if (!initialized) {
 initialized = true;
 SpringConfigHelper.appendBeanFromPackage(
 (AnnotationConfigWebApplicationContext) event.getApplicationContext(),
 basePackage);
 }
 }
 };
 }

 /**
 * 模板解析器
 * @return 解析器
 */
 @Bean
 public SpringResourceTemplateResolver templateResolver() {
 SpringResourceTemplateResolver resolver = new SpringResourceTemplateResolver();
 resolver.setPrefix("classpath:/template/");
 resolver.setSuffix(".html");
 resolver.setTemplateMode(TemplateMode.HTML);
 resolver.setCacheable(false);
 resolver.setCharacterEncoding("UTF-8");
 return resolver;
 }

 /**
 * 解析器
 * @param templateResolver 解析器
 * @return
 */
 @Bean
 public SpringTemplateEngine templateEngine(SpringResourceTemplateResolver templateResolver) {
 SpringTemplateEngine engine = new SpringTemplateEngine();
 engine.setTemplateResolver(templateResolver);

 return engine;
 }
 /**
 * 視圖解析器
 * @param templateEngine 解析器
 * @return 視圖解析
 */
 @Bean
 public ThymeleafViewResolver viewResolver(SpringTemplateEngine templateEngine) {
 ThymeleafViewResolver resolver = new ThymeleafViewResolver();
 resolver.setTemplateEngine(templateEngine);
 resolver.setCharacterEncoding("UTF-8");

return resolver;
 }
}

UndertowServer 的啟動方法：

public int start() {
    DeploymentInfo servletBuilder = Servlets.deployment()
            .setClassLoader(UndertowServer.class.getClassLoader())
 .setContextPath("/TAE/rest/v1")
 .setDeploymentName("test.war")
 .addServletContextAttribute(
 SpringContextListener.PARENT_CONTEXT, context)
 .addListeners(
 Servlets.listener(SpringContextListener.class))
 .addServlets(
 Servlets.servlet("resource", DispatcherServlet.class)
 .addInitParam("contextClass",
 "org.springframework.web.context.support"
 + ".AnnotationConfigWebApplicationContext")
 .addInitParam("contextConfigLocation",
 configClass)
 .addMapping("/*")
 .setLoadOnStartup(1)
 )
 .addServletContextAttribute(WebSocketDeploymentInfo.ATTRIBUTE_NAME,
 new WebSocketDeploymentInfo()
 .setBuffers(new DefaultByteBufferPool(true, 100))
 );

 DeploymentManager manager = Servlets.defaultContainer()
 .addDeployment(servletBuilder);
 manager.deploy();

 try {
 PathHandler path = Handlers.path(Handlers.redirect("/"))
 .addPrefixPath("/", manager.start());

 server = Undertow.builder()
 .addHttpListener(port, host)
 .setHandler(path)
 .build();

 server.start();
 } catch (Exception e) {
 log.fatal("cannot start web server", e);
 return CommonError.FATAL_FAIL;
 }
 return CommonError.SUCCESS;
}
