Question

I have configured a spring boot application but on booting the application,I am getting mapping error as below

Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Not Found, status=404).
No message available

.I have gone through the below link and have updated my controller to be part of root package containing the main class. This application has no explicit mapping for /error

I have used below mentioned configuration/code for my application:

build.gradle

buildscript {
    ext {
        springBootVersion = '2.1.1.RELEASE'
    }
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'

group = 'com.ticket'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = 1.8

repositories {
    mavenCentral()
}


dependencies {
    implementation('org.springframework.boot:spring-boot-starter-data-jpa')
    implementation('javax.servlet:jstl')
    implementation('org.springframework.boot:spring-boot-starter-web')
    runtimeOnly('com.h2database:h2')
    testImplementation('org.springframework.boot:spring-boot-starter-test')
}

TicketController.java

package com.ticket.controller;

import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.servlet.ModelAndView;

@RestController
public class TicketController {

    static Logger log = LogManager.getLogger();

    @RequestMapping(value = "/", method = RequestMethod.GET)
    public ModelAndView homeScreen(ModelMap model) {
        return new ModelAndView("view");
    }   
}

application.properties

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

Jsp path

src/main/webapp/WEB-INF/jsp/view.jsp

Answer 1

By default Spring boot does not provide ability to resolve Jsp for view layer. Adding in below property to

build.gradle

solved the issue

implementation('org.apache.tomcat.embed:tomcat-embed-jasper')
