I am new in the Spring Boot Application development.I am doing simple spring boot application using spring boot version 1.4.3 Release version and Spring 4.3.5.RELEASE version. I am successfully in the configuration of Mysql database configuration. Also table get created while running Spring Boot main class.
Below is Spring Boot project directory structure :
SpringBootApp[boot]
src/main/java
-config
-controller
-dto
-entity
-repository
-service
src/main/resources
-application.properties
src/test/java
src/main/webapp
/recources/css
/resources/images
/resources/js
/WEB-INF/view/jsp/main.jsp
I created DBConfig.java file which having DB related functionality like datasource creation,jpa transaction management.
Below is WebMVC configuration file:
@EnableWebMvc
@Configuration
@Import(DBConfig.class)
@ComponentScan(basePackages = { "com.tms" })
public class SpringWebConfig extends WebMvcConfigurerAdapter {
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
}
@Bean
public InternalResourceViewResolver viewResolver() {
InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
viewResolver.setViewClass(JstlView.class);
viewResolver.setPrefix("/WEB-INF/view/");
viewResolver.setSuffix(".jsp");
return viewResolver;
}
@Override
public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
configurer.enable();
}
}
Below is App Context initializer file :
public class WebAppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
@Override
protected Class<?>[] getRootConfigClasses() {
return new Class[] { DBConfig.class };
}
@Override
protected Class<?>[] getServletConfigClasses() {
return new Class[] { SpringWebConfig.class };
}
@Override
protected String[] getServletMappings() {
return new String[] { "/" };
}
}
I also added below line of code in application.properties file to locate jsp pages and to deactivate thymeleaf template.
spring.mvc.view.prefix: /WEB-INF/jsp/
spring.mvc.view.suffix: .jsp
spring.thymeleaf.check-template-location=false
Below is Spring Controller java file:
@RequestMapping("/")
public class IndexController {
@RequestMapping(method = RequestMethod.GET)
public String printWelcome(ModelMap model) {
model.addAttribute("title", "Hello world!");
return "main";
}
}
Below jsp sample page :
/WEB-INF/jsp/main.jsp
<%@taglib uri="http://www.springframework.org/tags/form" prefix="form"%>
<html>
<head>
<title>Spring Boot</title>
</head>
<body>
<h2>Test Page</h2>
<table>
<tr>
<td>Title</td>
<td>${title}</td>
</tr>
</table>
</body>
</html>
Spring Boot Application successfully get started.
Below is STS console output :

When i type url http://localhost:8080/ in the browser it will give below message :
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).
Also i tried http://localhost:8080/SpringBootApp/ url in the browserit will show below message :
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.
Thu Jan 12 04:33:26 IST 2017
There was an unexpected error (type=Not Found, status=404).
/SpringBootApp/
No any error message printed in the STS console.
I would be thankful if anybody have solution/ to suggest other approach for the same.
