UndertowServer+SpringMVC+Thymeleaf模板引擎构建轻量级的web项目

这两周需要写一个页面来请求另一个服务中的接口，服务器采用了超轻量级的undertow，模板引擎采用的是Thymeleaf，在寻找页面资源位置这个地方难住了我。下面分享一下，这方面的代码。

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调该函数     * 通过该机制可以动态扩展bean实例配置     * 用于工作服务框架加载工作服务实现相关bean     *     * @param basePackage 扩展bean扫描路径     * @return ApplicationListener实例     */    @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;    }    /**     * 视图解析器     * @param templateEngine 解析器     * @return  视图解析     */    @Bean    public ThymeleafViewResolver viewResolver(SpringTemplateEngine templateEngine) {        ThymeleafViewResolver resolver = new ThymeleafViewResolver();        resolver.setTemplateEngine(templateEngine);        resolver.setCharacterEncoding("UTF-8");

return resolver;    }}

UndertowServer 的启动方法：

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;}
