Field personRepositary in () required a bean of type () that could not be found - mysql

I am trying to run a spring developed web app and I'm getting the following error.
My folder structure is as follows.
Here is my PersonRepositary.java code which is inside the repositary folder.
package com.travelx.travelx.repositary;
import org.springframework.data.repository.CrudRepository;
import com.travelx.travelx.models.Person;
public interface PersonRepositary extends CrudRepository<Person, Integer> {
}
The RegisterController.java file which is in the controllers folder is ac follows.
package com.travelx.travelx.controllers;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import com.travelx.travelx.models.Person;
import com.travelx.travelx.repositary.PersonRepositary;
#RestController
#RequestMapping("register")
public class RegisterController {
#Autowired
private PersonRepositary personRepositary;
#PostMapping("login")
public String registerPerson(#RequestBody Person person) {
personRepositary.save(person);
return "You are Registered!";
}
}
And the TravelXApplication.java file which is in the controllers is below.
package com.travelx.travelx.controllers;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.domain.EntityScan;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
#SpringBootApplication
#ComponentScan
#EntityScan
#EnableJpaRepositories
public class TravelxApplication {
public static void main(String[] args) {
SpringApplication.run(TravelxApplication.class, args);
}
}
I'm trying to make a web page where a person can register to a site. Here, I'm using xampp as my platform to handle the back end. As shown in the image, the controllers, repositories and and models are implemented in separate folders. I'm new to Spring. So no matter how hard I to find what the problem is, I cant seem to find it. Can some one help me please?
--------------UPDATE------------------
I've moved my TravelXApplication.java to the com.travelx.travelx and now this error is gone.Spring works fine. However when I open my form, insert data and try to save it, the browser gives me the following error.
How do I solve it?

Your PersonRepositary is not registered as a bean in your Spring context. In practice, this means that Spring is not be able to inject it in your RegisterController.
I suspect that #EnableJpaRepositories, #EntityScan and #ComponentScan are unnecessary in your main application class and are actually causing Spring automatic configuration to be overridden. Try deleting these three annotations from TravelxApplication.
Here's the answer to why it should still work without annotations.
Update: just noticed that your TravelxApplication is located in the controllers package, but then it won't have visibility to your repository. Make sure to move your main class to the com.travelx.travelx package.

Initialization Error for Junit in Eclipse

I have configured Cucumber Maven project and getting Initialization error while executing my RunTest.java file:
package annotation;
import org.junit.runner.RunWith;
import cucumber.junit.Cucumber;
#RunWith(Cucumber.class)
#Cucumber.Options(format = {"pretty", "html:target/cucumber"})
public class RunTest { }
I had included hamcrest-library files too but still I don't know what I have left out.
Use the below code instead...
package annotation;
import org.junit.runner.RunWith;
import cucumber.api.junit.Cucumber;
import cucumber.api.CucumberOptions;
#RunWith(Cucumber.class)
#CucumberOptions(plugin = { "pretty", "html:target/cucumber" })
public class RunTest {
}
Two import statements were wrong. Cucumber.Options was not correct it is CucumberOptions. format is now deprecated, use plugin.

WELD-001318: Ambigous dependency when using JaxbJsonProvider and JsonProvider on WAS Liberty

I am running a server under WebSphere Application Server (17.0.0.1/wlp-1.0.16.cl170120170227-0220) and have added the changes recommended in this post (How to change Jackson version in JAX-RS app (WebSphere Liberty)) for upgrading the level of Jackson in WAS Liberty. I am using Postman to test my server. When I submit a GET request for an object, it completes successfully. (After adding this change, my server can return my objects in either XML or JSON.). However, I am now seeing these messages in the server console when my server builds the Response object.
[INFO ] FFDC1015I: An FFDC Incident has been created: "org.jboss.weld.exceptions.AmbiguousResolutionException: WELD-001318: Cannot resolve an ambiguous dependency between:
- Managed Bean [class com.ibm.zss.boundary.JaxbJsonProvider] with qualifiers [#Any #Default],
- Managed Bean [class com.ibm.zss.boundary.JsonProvider] with qualifiers [#Any #Default] com.ibm.ws.jaxrs20.cdi.component.JaxRsFactoryImplicitBeanCDICustomizer 425" at ffdc_17.06.13_15.59.57.0.log
com.ibm.zss.boundary.JaxbJsonProvider and com.ibm.zss.boundary.JsonProvider are the classes I added based on the instructions from the previous post.
I also updated my server.xml to include:
<feature>jsonp-1.0</feature>
<feature>jaxrs-2.0</feature>
I've been searching for solutions for handling a WELD ambiguousResolutionException, but most of them address issues with classes where the developer has control over what is being injected. So, I don't know if I have any control over the code that I need to change for this problem.
For completeness, here are the classes which I added to my application:
import javax.ws.rs.Consumes;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.ext.Provider;
import com.fasterxml.jackson.jaxrs.json.JacksonJaxbJsonProvider;
#Provider
#Consumes(MediaType.APPLICATION_JSON)
#Produces(MediaType.APPLICATION_JSON)
public class JaxbJsonProvider extends JacksonJaxbJsonProvider {
}
import javax.ws.rs.Consumes;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.ext.Provider;
import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.jaxrs.json.JacksonJsonProvider;
#Provider
#Consumes(MediaType.APPLICATION_JSON)
#Produces(MediaType.APPLICATION_JSON)
public class JsonProvider extends JacksonJsonProvider {
public JsonProvider() {
ObjectMapper objectMapper = new ObjectMapper();
objectMapper.setVisibility(objectMapper.getVisibilityChecker().withFieldVisibility(JsonAutoDetect.Visibility.ANY));
setMapper(objectMapper);
}
}
Can you either mark it an #Specializes or an #Alternative with low #Priority, depending on whether you want it to be used for injection points?

JerseyTest WebTarget POST support

I am developing a light weight server App with a RESTful api implemented with Jersey 2.12 and Jackson 2.
I am writing tests while developing using JUnit and JerseyTest. I know that my Jersey Resources work as expected including the marshalling from and to JSON because I tested them manually with the PostMan Chrome plugin.
My GET tests with query parameters work well too, based on the example in the Jersey documentation
Here is a simplified (I have left out boilerplate code to make the idea clearer) example of a test I'd like to write:
import static org.junit.Assert.assertTrue;
import javax.ws.rs.client.Entity;
import javax.ws.rs.client.WebTarget;
import javax.ws.rs.core.Application;
import javax.ws.rs.core.Response;
import org.glassfish.jersey.server.ResourceConfig;
import org.glassfish.jersey.test.JerseyTest;
import org.junit.Test;
import com.acme.api.rest.SessionsEndPoint;
import com.acme.api.rest.beans.UserCredentialsBean;
public class TestSession extends JerseyTest {
#Override
protected Application configure() {
return new ResourceConfig(SessionsEndPoint.class);
}
#Test
public void test() {
UserCredentialsBean userCredentialsBean = new UserCredentialsBean();
userCredentialsBean.setUserId("alice");
userCredentialsBean.setPassword("secret");
WebTarget theTarget = target("sessions/login");
Response response = theTarget.request().post( Entity.entity(UserCredentialsBean.class, "application/json"));
assertTrue(true);
}
}
The basic problem I have is that I cannot find any documentation on how to properly use the WebTarget class for post requests. the WebTarget theTarget is constructed correctly but the line:
Response response = theTarget.request().post( Entity.entity(UserCredentialsBean.class, "application/json"));
does not work.
As I understand the WebTarget class is fairly new in the JerseyTest framework. Is there anybody who can point me at any recent documentation, examples, or just explain here how I can get this to work?
I did do a lot of googling before I posted my question here, but after checking back my eyes suddenly fell on this Related Question. I did search on SO several times but never found this question. Anyway, here's the solution to my problem:
I started implementing as explained in the accepted answer and got it to work quickly.
Then I decided that you it should be possible to avoid using JSON string representations at all, and I got that to work to.
The code above works if modified as follows:
import static org.junit.Assert.assertTrue;
import javax.ws.rs.client.Entity;
import javax.ws.rs.client.WebTarget;
import javax.ws.rs.core.Application;
import javax.ws.rs.core.Response;
import org.glassfish.jersey.server.ResourceConfig;
import org.glassfish.jersey.test.JerseyTest;
import org.junit.Test;
import com.acme.api.rest.SessionsEndPoint;
import com.acme.api.rest.beans.UserCredentialsBean;
public class TestSession extends JerseyTest {
#Override
protected Application configure() {
return new ResourceConfig(SessionsEndPoint.class);
}
#Test
public void test() {
UserCredentialsBean userCredentialsBean = new UserCredentialsBean();
userCredentialsBean.setUserId("alice");
userCredentialsBean.setPassword("secret");
LoginResponseBean loginResponseBean =
target("sessions/login")
.request(MediaType.APPLICATION_JSON_TYPE)
.post(
Entity.entity(
userCredentialsBean,
MediaType.APPLICATION_JSON_TYPE
),
LoginResponseBean.class
);
assertTrue(
loginResponseBean.isSuccess()
&&
loginResponseBean.getToken().length()==36
);
}
}
LoginResponseBean is a plain Java Bean. Just getters and setters and a default constructor.
Marshalling to- and from JSON is done by the framework, either by moxy or jackson as the JSON provider.

JUnit NoClassDefFoundError

I'm new at JUnit and use inteliji idea.
import org.junit.Test;
import org.junit.Ignore;
import org.junit.runner.RunWith;
import org.junit.runners.JUnit4;
import java.util.Date;
import static org.junit.Assert.*;
public class TestQuote {
#Test
public void testQuote() {
Date date = new Date(System.currentTimeMillis());
Quote quote=new Quote("a",date,200.0,300.0,100.0,107.0,1.0);
assertNull("Object is null",quote);
assertEquals("Symbol is ok",quote.getSymbol(),"a");
assertEquals("Date is ok",quote.getDate(),System.currentTimeMillis());
assertEquals("Open price is ok",quote.getOpenPrice(),200.0);
assertEquals("High price is ok",quote.getHighPrice(),300.0);
assertEquals("Low price is ok",quote.getLowPrice(),100.0);
assertEquals("Close price is ok",quote.getClosePrice(),107.0);
}
}
Here is code of my test class. JUnit.jar is added to classpath but when i run it it says:
java.lang.NoClassDefFoundError: org/hamcrest/SelfDescribing
Any sollutions?
BTW main program work OK.
Go to the JUnit web site: http://junit.org/
Then click on "Download and install Guide" : https://github.com/junit-team/junit/wiki/Download-and-Install
Then read:
Download the following JARs and put them on your test classpath:
junit.jar
hamcrest-core.jar

AS3 Error #1065

I must be missing something simple here, but in my main app, I import my Pages class, which in turn imports and dynamically instantiates one of two page types. Unfortunatley it only results in the error: ReferenceError: Error #1065: Variable PageA is not defined. (when I call Pages.load("A");)
Pages
package pages
{
import pages.PageA;
import pages.PageB;
import flash.display.Sprite;
import flash.utils.getDefinitionByName;
public class Pages
{
public static function load(pageType:String):void
{
var pageClass:Class = getDefinitionByName("pages.Page"+pageType) as Class;
}
}
}
PageA
package pages
{
import flash.display.Sprite;
public class PageA extends Sprite
{
public function PageA()
{
trace("PageA init");
}
}
}
PageB
package pages
{
import flash.display.Sprite;
public class PageB extends Sprite
{
public function PageB()
{
trace("PageB init");
}
}
}
Exactly, the compiler plainly didn't include those classes in the compiled SWF. I've hit this wall somewhere before, when I've tried instantiating via generated string (in my case 'Gem'+an integer), and received about the same error. I went around it by creating a dummy constant, enumerating all the classes I plan to use, this made the compiler aware of this. So, make the following:
private static const PAGES:Array=[PageA, PageB];
And compile. Should do. Also, you don't need to import parts of "pages" package, they are already visible in your project, since your "Pages" class belongs to the same package.
