Führen Sie meine Spring -Boot -Anwendung (Beispielprogramm zum Posten von Jason in Spring Ruhestand Webvise WebService) in Eclipse erfolgreich aus. Wenn ich jedoch den Befehl MVN -Paket verwende, um die JAR -Datei abzurufen. Habe die folgende Nachricht. Jeder könnte helfen. < /P>

Code: Select all

: Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'controllerSimple' defined in file
< /code>

 controllerSimple.java

package com.example;

import java.io.IOException;
import java.util.HashMap;
import java.util.Map;

import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class ControllerSimple {

AddressList addressList;
ControllerSimple (){
addressList = new AddressList();
}

@RequestMapping("/hello")
public String index() {
return "Hello World";
}

@RequestMapping(value="/crud_c_final", method=RequestMethod.POST)
public ResponseEntity create_key(@RequestBody AnEntity anentity) throws SMException, IOException{

System.out.println("request create received!");
if(anentity!=null){
String key = anentity.getKey();
String name = anentity.getValue().getName();
String address = anentity.getValue().getAddress();

...
...
}
< /code>

MVN Paket erhalten folgende Nachricht: < /p>
