Please help me to fix this issue.. Thanks a lot in advance...

Answer 1

For me (spring-boot-starter-parent version 2.0.5.RELEASE) it worked changing the path in this way:

src/main/resources/WEB-INF/view/index.html ? src/main/resources/META-INF/resources/view/index.html (for some reason it seemed not liking the WEB-INF name and it needed the nested resources directory).

It seems to work also with src/main/resources/resources/view/index.html

In these cases you don't even need to add the @EnableWebMvc annotation and implement the WebMvcConfigurer (prefix and suffix configured in application.properties are enough).

I add to my answer also a clarification about the MVC configuration taken from the Spring Boot Reference Guide:

27.1.1 Spring MVC Auto-configuration

If you want to keep Spring Boot MVC features and you want to add additional MVC configuration [...] you can add your own @Configuration class of type WebMvcConfigurer but without @EnableWebMvc.

If you want to take complete control of Spring MVC, you can add your own @Configuration annotated with @EnableWebMvc.

76.7 Switch off the Default MVC Configuration

The easiest way to take complete control over MVC configuration is to provide your own @Configuration with the @EnableWebMvc annotation. Doing so leaves all MVC configuration in your hands.

Answer 2

Removing of @EnableWebMvc annotation works for me in Spring Boot Project.

Answer 3

In your code you have defined suffix and prefix

spring.mvc.view.prefix=/WEB-INF/view/
spring.mvc.view.suffix=.html

So all page in your request will convert to html file automatically,so you need to change return "index.html"; to return "index";

Change to

@Controller 
public class HomeController {
    @RequestMapping("/")
    public String index() {
        return "index";
    }
}

Answer 4

I was getting this error when doing a CURL request in my spring boot application:

{"timestamp":1566549840380,"status":500,"error":"Internal Server Error","message":"Could not resolve view with name 'createApiKey' in servlet with name 'dispatcherServlet'","path":"/createApiKey"}

I fixed it by changing from @Controller to @RestController (which is a combination of @Controller and @ResponseBody) like this:

@RestController
public class ApiKeyController {
    ...
    @GetMapping("/createApiKey")
    public DeferredResult<CreateApiKeyResp> createApiKey(@RequestParam long userId) {
        ...

Answer 5

In my case I was missing the thymeleaf dependency.

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

Answer 6

Circular view path changes for spring-boot application getting jsp pages

Changes required in application.properties

spring.thymeleaf.mode=HTML5
spring.thymeleaf.enabled=false

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

Changes in pom.xml

    <dependency>
        <groupId>org.apache.tomcat.embed</groupId>
        <artifactId>tomcat-embed-jasper</artifactId>
    </dependency>

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