springboot整合jsp,thymeleaf.源代码下载

By：Roy.LiuLast updated：2019-09-26

在整合项目过程中，还有可能遇到有用 jsp 写的，有用thymeleaf写的。这时候也需要整合. 整合方式很简单，spring mvc 本身就支持，所以在springboot中一样支持，只不过是xml配置，变成了一个启动时加载的类而已。在我的例子用的是AppConfig类.

1. 整个项目工程结构
用了之前用来测试springboot 整个hibernate, mybatis的例子。

2. AppConfig类，用来配置视图解析，以及静态资源文件映射

@Configuration
public class AppConfig implements WebMvcConfigurer {
	
		
	@Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
     
		registry.addResourceHandler("/static/**")
                .addResourceLocations(                  
                    "classpath:/static/"                   
            	); 
    }
	
	@Bean
    public ViewResolver viewResolver() {
        InternalResourceViewResolver resolver = new InternalResourceViewResolver();
        resolver.setPrefix("/WEB-INF/");
        resolver.setSuffix(".jsp");
        resolver.setViewNames("jsp/*");
        resolver.setOrder(2);
        return resolver;
    }

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

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

    @Bean
    public ThymeleafViewResolver viewResolverThymeLeaf() {
        ThymeleafViewResolver viewResolver = new ThymeleafViewResolver();
        viewResolver.setTemplateEngine(templateEngine());
        viewResolver.setCharacterEncoding("utf-8");
        viewResolver.setViewNames(new String[]{"html/*"});
        viewResolver.setOrder(1);
        return viewResolver;
    }

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

}

3. 运行起来，测试运行结果:
