springboot-jsp

An example of Spring Boot application that uses an embedded tomcat and jsp.

Use JSP in your current Spring Boot project

1. Add required dependencies:

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>jstl</artifactId>
</dependency>
<dependency>
    <groupId>org.apache.tomcat.embed</groupId>
    <artifactId>tomcat-embed-jasper</artifactId>
</dependency>
<dependency><!-- Optional, use this only when you need spring security taglibs -->
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-taglibs</artifactId>
</dependency>

2. Add view prefixes in application properties (yaml example below)

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

3. Configure view resolver:

@EnableWebMvc
@Configuration
public class WebConfig extends WebMvcConfigurerAdapter {

    @Value("${spring.mvc.view.prefix}")
    private String prefix;

    @Value("${spring.mvc.view.suffix}")
    private String suffix;

    /**
     * Configures view resolver for jsp views.
     */
    @Bean
    public InternalResourceViewResolver setupViewResolver() {
        InternalResourceViewResolver resolver = new InternalResourceViewResolver();
        resolver.setPrefix(prefix);
        resolver.setSuffix(suffix);
        resolver.setViewClass(JstlView.class);
        return resolver;
    }
}

4. Create jsp views in src/main/webapp/WEB-INF/ directory.
