Spring學習日誌之Spring MVC啓動配置

對DispatcherServlet進行配置

Spring MVC的配置實際上就是對DispatcherServlet的配置

public class DispatcherServletConfig extends AbstractAnnotationConfigDispatcherServletInitializer
{
	@Override
	protected Class<?>[] getRootConfigClasses()     // 加載自定義的配置類
	{
		return new Class<?>[]{BeanConfig.class, SecurityConfig.class};
	}

	@Override
	protected Class<?>[] getServletConfigClasses()  // 加載web配置類，如viewResolver
	{
		return new Class<?>[]{WebConfig.class};
	}

	@Override
	protected String[] getServletMappings()
	{
		return new String[]{"/"};
	}
}

WebConfig的實現

@Configuration
@EnableWebMvc   // 在此開啓WebMvc
@ComponentScan(basePackageClasses = {BasePackageMarker.class})
public class WebConfig extends WebMvcConfigurerAdapter
{
	@Bean
	public ViewResolver viewResolver(TemplateEngine templateEngine)
	{
		ThymeleafViewResolver viewResolver = new ThymeleafViewResolver();
		viewResolver.setTemplateEngine(templateEngine);
		viewResolver.setCharacterEncoding("UTF-8");

		return viewResolver;
	}

	@Bean
	public TemplateEngine templateEngine(ITemplateResolver templateResolver)
	{
		SpringTemplateEngine templateEngine = new SpringTemplateEngine();
		templateEngine.setTemplateResolver(templateResolver);
		templateEngine.addDialect(new SpringSecurityDialect());
		return templateEngine;
	}

	@Bean
	public ITemplateResolver templateResolver()
	{
		SpringResourceTemplateResolver templateResolver = new SpringResourceTemplateResolver();
		templateResolver.setPrefix("/WEB-INF/templates/");
		templateResolver.setSuffix(".html");
		templateResolver.setTemplateMode("HTML5");
		templateResolver.setCharacterEncoding("UTF-8");
		templateResolver.setCacheable(false);

		return templateResolver;
	}

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