spring boot默认使用什么样的view技术

Question

What kind of view technology used in spring boot by default when I add the 'Spring Boot Web Starter'. If I want to use the JSP, I need to include the 'tomcat-embed-jasper' or 'Spring Boot Thymeleaf Starter' for thymeleaf templates. So I would like to know the default view technology of 'Spring Boot Web Starter'

Answer 1

By default there is no view You need to configure and add their dependencies.If You are using Spring Boot older versions then You can refer above answer but if You are using Spring Boot 2 then add on more dependency for thymeleaf-

        <dependency>
            <groupId>nz.net.ultraq.thymeleaf</groupId>
            <artifactId>thymeleaf-layout-dialect</artifactId>
        </dependency>
    <dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>

Answer 2

JSP is supported by Spring out-of-the-box.

It can be configured like this

@EnableWebMvc
@Configuration
public class ApplicationConfiguration implements WebMvcConfigurer {

    @Bean
    public ViewResolver jspViewResolver() {
        InternalResourceViewResolver bean = new InternalResourceViewResolver();
        bean.setPrefix("/WEB-INF/views/");
        bean.setSuffix(".jsp");
        return bean;
    }
}

or in properties file

spring.mvc.view.prefix: /WEB-INF/views/
spring.mvc.view.suffix: .jsp

For Thymeleaf

Spring Boot will provide auto-configuration for Thymeleaf with below dependency in pom.xml

Please make a note of version used. Also you might need to provide view properties like above

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-thymeleaf</artifactId>
    <version>1.5.6.RELEASE</version>
</dependency>
