</dependencies>

application.properties:

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

spring.session.store-type=none

spring.datasource.url:jdbc:mysql://localhost/phonebook?useSSL=false
spring.datasource.username:root
spring.datasource.password:root
spring.datasource.driver:com.mysql.jdbc.Driver

spring.jpa.properties.hibernate.dialect:org.hibernate.dialect.MySQL5Dialect
logging.level.org.hibernate.SQl:debug

class WebMvcConfig:

@Configuration
//@EnableWebMvc
public class WebMvcConfig extends WebMvcConfigurerAdapter {

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

@Bean
public InternalResourceViewResolver viewResolver() {
    InternalResourceViewResolver resolver = new      InternalResourceViewResolver();
    resolver.setPrefix("WEB-INF/jsp/");
    resolver.setSuffix(".jsp");
    return resolver;
}

Controller :

@Controller
public class MainController {

@RequestMapping(value = "/index", method = RequestMethod.GET)
@ResponseBody
public String index() {
   return "index";
}
}

SpringBootApplication :

//@Configuration
//@ComponentScan
//@EnableAutoConfiguration
@SpringBootApplication
public class PhoneBookApplication extends SpringBootServletInitializer{

public static void main(String[] args) {
    SpringApplication.run(PhoneBookApplication.class, args);
}
}

After deleting @ResponseBody from my Controller I got this exception:

There was an unexpected error (type=Internal Server Error, status=500). Error resolving template "index", template might not exist or might not be accessible by any of the configured Template Resolvers

delete @ResponseBody from your MainController if you want to return index.html — Patrick

To solve your issue:

There was an unexpected error (type=Internal Server Error, status=500). Error resolving template "index", template might not exist or might not be accessible by any of the configured Template Resolvers

Try to change your application like this:

You dont need to have a WebMvcConfig class for using template resolver for jsp. You configure the suffix and prefix correctly in your application.properties file. So delete this class.

@SpringBootApplication
public class PhoneBookApplication extends SpringBootServletInitializer{

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(PhoneBookApplication.class);
    }

    public static void main(String[] args) {
        SpringApplication.run(PhoneBookApplication.class, args);
    }
}

Controller:

@Controller
public class MainController {

    @RequestMapping(value = "/index", method = RequestMethod.GET)
    public String index() {
       return "index";
    }
}

You dont need a template folder in your resource folder and the dependency in your pom, if you dont use thymeleaf as template enginge. You can delete

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

You need to remove the @ResponseBody from the controller method in order to dispatch the view (index.jsp), otherwise the response will be returned as part of the http body.

@ResponseBody Annotation that indicates a method return value should be bound to the web response body.

Please remove this application.properties:

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

Also, Remove it from Controller @ResponseBody

@Controller
public class MainController {

@RequestMapping(value = "/index", method = RequestMethod.GET)
public String index() {
   return "index";
}
}

In my scenario, i'm deploying a Angular application with Spring MVC API.

So the other solutions were not working for me, So i used servlet-mapping from the web.xml file.

Here is example of the Servlet and its Mappling in the web.xml file.

<servlet>
    <servlet-name>index</servlet-name>
    <jsp-file>/index.html</jsp-file>
</servlet>

<servlet-mapping>
    <servlet-name>index</servlet-name>
    <url-pattern>/login/*</url-pattern>
</servlet-mapping>

The web.xml file need to be placed in the Web-INF directory.

Here is the structure of the web.xml file

<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app>
... Your configurations
</web-app>
