I want create Spring boot project with Spring MVC.
I created Controller:
#Controller
public class HelloController {
#RequestMapping("/")
public ModelAndView index() {
ModelAndView modelAndView = new ModelAndView("start");
modelAndView.addObject("message", "hello");
return modelAndView;
}
}
Application Class
#ComponentScan
#EnableAutoConfiguration
public class Application {
public static void main(String[] args) {
ApplicationContext ctx = SpringApplication.run(Application.class, args);
System.out.println("Let's inspect the beans provided by Spring Boot:");
String[] beanNames = ctx.getBeanDefinitionNames();
Arrays.sort(beanNames);
for (String beanName : beanNames) {
System.out.println(beanName);
}
}
}
and html page start.html

My project is build but when i tried open page I have error
http://localhost:8080/
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing
this as a fallback.
Wed Jun 15 14:20:53 ALMT 2016 There was an unexpected error (type=Not
Found, status=404). No message available
I tried add WebMvcConfigurerAdapter but not helped.
EDIT
Now I can return JSON
#RequestMapping("/")
public #ResponseBody Greeting index() {
return new Greeting(1L, "sefsfdf");
}
but How can i return ModelView?

I want to map the form action with the controller method as below, but i get the 404 page not found error.
my JSP page:
<h1>Welcome to SportyShoes</h1>
<form action="loginaction" method="post">
<input type="text" name="adminname">
<input type="password" name="password">
<button>Submit</button>
</form>
my controller page:
#Controller
public class AdminController {
#Autowired
private AdminService adminService;
#RequestMapping(value = "/loginaction", method = RequestMethod.POST)
public String loginAction(ModelMap map, #RequestParam(value="adminname") String adminName, #RequestParam(value="password") String password) {
Admin admin = adminService.authenticate(adminName, password);
if(admin == null) {
map.addAttribute("error", "admin name or password is wrong");
return null;
}
return "entry";
}
}
but i get the error:
There was an unexpected error (type=Not Found, status=404).
JSP file [/WEB-INF/views/loginaction.jsp] not found

All my HTML files are in /resources/templates path.
You are returning "new_product", in the /new method.
You have to create a new_product view (new_product.jsp / new_product.html..) and do whatever you want to inside, then it will be ok and you'll get a 200 response.
If your file already exists, maybe the path is not correct and you have to configure it. Try to put the html file in static folder otherwise add your path in your application.properties
I am trying to map index1.jsp from controller.
Here is my controller method code:
#GetMapping({"/", "/hello"})
public String hello(Model model, #RequestParam(value="name", required=false, defaultValue="World") String name) {
model.addAttribute("name", name);
return "index1";
}
This is WebConfiguration:
#Configuration
public class WebConfiguration implements WebMvcConfigurer {
#Bean
public UrlBasedViewResolver viewResolver() {
UrlBasedViewResolver resolver
= new UrlBasedViewResolver();
resolver.setPrefix("/WEB-INF/jsp/");
resolver.setSuffix(".jsp");
resolver.setViewClass(JstlView.class);
return resolver;
}
}

I am getting error: HTTP Status 500 – Internal Server Error
This is from console:

...
org.thymeleaf.exceptions.TemplateInputException: Error resolving template [index1], template might not exist or might not be accessible by any of the configured Template Resolvers
I think it look up at templates folder, and not in WEB-INF/jsp. If I try to map html file from templates it works. But with JSP makes problem.
Here it is a structure of application:

There are following steps you need to follow if you want to work with Spring boot + JSP instead of thymeleaf.
Remove thymeleaf dependency from pom.xml
Add below dependencies in pom.xml (Jasper to compile JSPs)
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
</dependency>
<!-- Need this to compile JSP -->
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
<scope>provided</scope>
</dependency>
Refer https://mkyong.com/spring-boot/spring-boot-hello-world-example-jsp/ for more information.
I'm developing simple Spring Boot MVC application. Previously I had everything working with just Spring + Hibernate (that is there was servlet.xml etc.) and I'm trying to rebuild project to use Spring Boot. Althought I have read many answers on SO I still can't fix Spring Boot not finding my .jsp files - it displays whitelabel error page.
Many answers on SO are about including tomcat-embed-jasper and jstl in pom.xml but I already have it. I'm using IntelliJ IDEA 17 Ultimate, Tomcat 8.5.13, latest versions of Spring and Spring Boot.

You are using Spring Boot but your pom is riddled with conflicting dependencies. For starters cleanup your pom.xml. Also in your pom you should take into account what is being done in the JSP Samples pom.xml (Which means at least make the spring-boot-starter-tomcat provided instead of the default compile scope.
Finally you don't need the maven-compile and maven-war plugins as those are already inherited from the parent.

Also take into account the limitations there are when using Spring Boot with JSPs.
However the actual problem is your project structure, you are using Maven with should have a src/main/java directory for your java sources and all your web related things should be in src/main/webapp instead of web, further non java related resources should be in src/main/resources. Due to not having this default structure files aren't going to be copied to the correct location (actually they will be ignored).
