Main Application Class: (It was going to be using JSP but realized the trouble with Spring Boot):
package com.MBS.Consulting.jsp;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
import org.springframework.context.annotation.Configuration;
#Configuration
#SpringBootApplication(scanBasePackages="com.MBS.Consulting.jsp")
public class SampleWebJspApplication extends SpringBootServletInitializer {
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(SampleWebJspApplication.class);
}
public static void main(String[] args) throws Exception {
SpringApplication.run(SampleWebJspApplication.class, args);
}
}
WelcomeController - In sub folder of main class (this controller is accessible):
package com.MBS.Consulting.jsp.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
#Controller
public class WelcomeController {
#GetMapping("/")
public String index() {
return "static/index";
}
#GetMapping("/Home")
public String welcome() {
return "Welcome/welcome";
}
#GetMapping("/ContactUs")
public String contactUs() {
return"Welcome/contact_Us";
}
#GetMapping("/AboutUs")
public String aboutUs() {
return "Welcome/about_us";
}
}
CustomerController - Does not even show that it is called with AOP. The package name is the same as the last controller. I do need to login using Spring Security to reach this page. It allows me to login and then gives me 404.
package com.MBS.Consulting.jsp.controller;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.DeleteMapping;

#Controller
#RequestMapping("/Customer")
public class CustomerController {
#Autowired
private CustomersService customerService;
#GetMapping("/Home")
public String customerHome() {
return "Customer/Customer_Home";
}
}
Security config:
Not sure if I really need this or not but added it just to make sure that it couldn't be causing the problem.
package com.MBS.Consulting.jsp.config;
import java.util.HashMap;
import java.util.Map;

}
)
.httpBasic();
return http.build();
}
}
Project structure:
I hope the image shows up due just to show the project structure and that I believe the controllers are in the correct location to not be a problem for Spring Boot.
In the logs for console I get no information at all when visit CustomerController, but I do get a 404 Error. The web address I visit is http://localhost:8080/Customer/Home to try to call CustomerController. I am unsure what will cause this and if someone could explain what I did wrong.
I did search on it and I was going to try and configure the dispatcher servlet but it should of been auto configured. I believe if it reaching one it should be able to reach the other if it is the same folder. Also I understand the it needs to be in the sub folder of the main class. Finally I checked to see if it was the mapped right since I used folders in the template folder.
While mappings were correct and the project structure is correct it was unable to reach controllers due to spring security. The security FilterChain in the screen shot is missing two asterisks on the permit all controllers.
this:
.antMatchers("/","/Welcome", "/Login").permitAll()
should be:
.antMatchers("/**","/Welcome/**", "/Login/**").permitAll()
Swagger Api Docs Image
I am working on adding / integrating swagger in my springboot project. I have tried different things but its not got fixed. All that is showing now is white page without any endpoints or controllers and just an empty page with swagger logo.
Swagger URL is : http://localhost:8080/swagger-ui.html
My swagger configurations are given below:
package com.app;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;
#SpringBootApplication(scanBasePackages = {"com.app.controller"})
public class StoreApplication extends SpringBootServletInitializer {
public static void main(String[] args) {
try {
SpringApplication.run(StoreApplication.class, args);
}catch (Throwable throwable){
System.out.println(throwable.toString());
throwable.printStackTrace();
}
}
}
Here is my controller code.
My Controller
package com.app.controller;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
#CrossOrigin
#RestController
public class CustomersController {
#RequestMapping(value = "/customers", method = RequestMethod.GET)
ResponseEntity<?> getAllCustomers(){
return ResponseEntity.status(HttpStatus.OK).body(null);
}
#RequestMapping(value = "/customer", method = RequestMethod.POST)
ResponseEntity<?> createCustomer(){
return ResponseEntity.status(HttpStatus.OK).body(null);
}
}
Here is the main class
Main Class
package com.app;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;
#SpringBootApplication(scanBasePackages = {"com.app.controller"})
public class StoreApplication extends SpringBootServletInitializer {
public static void main(String[] args) {
try {
SpringApplication.run(StoreApplication.class, args);
}catch (Throwable throwable){
System.out.println(throwable.toString());
throwable.printStackTrace();
}
}
}
This is my app config file
AppConfig
package com.app.config;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
#Configuration
public class AppConfig implements WebMvcConfigurer {
#Override
public void addViewControllers(ViewControllerRegistry registry){
// registry.addRedirectViewController("/docApi/v2/api-docs","/v2/api-docs");
registry.addViewController("/welcome").setViewName("Welcome");
}
}
First, try to add swagger config like this:
#EnableSwagger2
#Configuration
public class SwaggerConfig {
#Bean
public Docket productApi() {
return new Docket(DocumentationType.SWAGGER_2)
.select()
.apis(RequestHandlerSelectors.basePackage("com.app"))
.paths(PathSelectors.any())
.build();
}
}
then add some annotation in your controller like this:
package com.app.controller;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
#CrossOrigin
#RestController
#Api
public class CustomersController {
#RequestMapping(value = "/customers", method = RequestMethod.GET)
#ApiOperation(value = "get all", tags = "customer")
ResponseEntity<?> getAllCustomers(){
return ResponseEntity.status(HttpStatus.OK).body(null);
}
#RequestMapping(value = "/customer", method = RequestMethod.POST)
#ApiOperation(value = "create", tags = "customer")
ResponseEntity<?> createCustomer(){
return ResponseEntity.status(HttpStatus.OK).body(null);
}
}
hope this would fix your problem. Then try to access the url: http://127.0.0.1:8080/swagger-ui/index.html, pay attention not the url http://localhost:8080/swagger-ui.html.

I don't understand what is the problem. Its my first spring-boot application please help.
Im trying to mock a controller's post method. I want it to return status code 201(CREATED) . But it gives Status Code 200.
Given below is the code
This is my controller Class
package com.example.demo;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RestController;
public #RestController
class SomeController{
#PostMapping("/insertString")
public ResponseEntity<String> insertString(String str) {
return new ResponseEntity<>(new String("monster"),HttpStatus.CREATED);
}
}
This is my junit test Suit
package com.example.demo;
import static org.junit.Assert.*;
import static org.mockito.Mockito.when;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;
import static org.mockito.Mockito.anyString;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.Mockito.*;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.servlet.WebMvcTest;
import org.springframework.boot.test.mock.mockito.MockBean;
import org.springframework.http.HttpStatus;
import org.springframework.http.MediaType;
import org.springframework.http.ResponseEntity;
import org.springframework.stereotype.Controller;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.MvcResult;
import org.springframework.test.web.servlet.RequestBuilder;
import org.springframework.test.web.servlet.request.MockMvcRequestBuilders;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RestController;
#RunWith(SpringRunner.class)
#WebMvcTest(SomeController.class)
public class TestClass {
#Autowired
private MockMvc mockMvc;
#MockBean
private SomeController someController;
#Test
public void test() throws Exception {
ResponseEntity<String> entity = new ResponseEntity<>(HttpStatus.CREATED);
when(someController.insertString(anyString())).thenReturn(entity);
RequestBuilder requestBuilder = MockMvcRequestBuilders
.post("/insertString")
.accept(MediaType.APPLICATION_JSON)
.content("monkey")
.contentType(MediaType.APPLICATION_JSON);
MvcResult result = mockMvc.perform(requestBuilder)
.andExpect(status().isCreated())
.andReturn();
System.out.println(result.getResponse().getContentAsString());
}
}
The errorim getting is
java.lang.AssertionErrror:Status expected:<201> but was:<200>
Though i have mentioned the status as HttpStatus.CREATED in the RequestEntity object, Why am i getting 200.
Please if someone can help
Try to change
public ResponseEntity<String> insertString(String str)
to
public ResponseEntity<String> insertString(#RequestBody String str)
I've run the test with above code and it passed.
Trying out this tutorial from here.
Created a dynamic web project and the code as it is.
However when I deploy and run this on Tomcat, getting this exception:
org.apache.jasper.JasperException: java.lang.IllegalStateException: Neither BindingResult nor plain target object for bean name 'command' available as request attribute
org.apache.jasper.servlet.JspServletWrapper.handleJspException(JspServletWrapper.java:565)
org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:476)
org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:385)
I tried to google it and also tried modifying the controller class:
package com.tutorialspoint;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.portlet.ModelAndView;
#Controller
public class StudentController {
#RequestMapping(value="/student", method=RequestMethod.GET)
public ModelAndView student(){
ModelAndView mAndV = new ModelAndView("student");
mAndV.addObject("command",new Student());
return mAndV;
/*return new ModelAndView("student","command",new Student());*/
}
#RequestMapping(value="/addstudent", method=RequestMethod.POST)
public String addStudent(#ModelAttribute("SpringWeb")Student student, ModelMap model) {
model.addAttribute("name",student.getName());
model.addAttribute("age",student.getAge());
model.addAttribute("id",student.getId());
return "result";
}
}
But its not helping...
I know this must be an simple issue. But not getting what it is.
