Java 上下文初始化期间遇到异常-取消刷新尝试：org.springframework.beans.factory.BeanCreationException

在Eclipse中成功运行我的Spring启动应用程序（将jason发布到Spring RESTful webservice的示例程序）。但是，当我使用

mvn-package

命令获取jar文件时。收到以下消息。任何人都可以帮忙

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

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<AnEntity> 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();

这是您的主要错误：

Error creating bean with name 'controllerSimple' defined in file [C:\Users\MyPC\workspace\springb\target\classes\com\example\ControllerSimple.class]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.example.ControllerSimple]: Constructor threw exception; nested exception is java.lang.NoClassDefFoundError: org/apache/poi/util/HexDump

您应该添加更多的Apache POI依赖项：

<dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi</artifactId>
    <version>3.14</version>
</dependency>

org.apache.poi
poi
3.14

就快到了。仍然存在一些错误，但要少得多。我已经编辑了帖子，并把错误放在那里。
