Question

我正在使用tomcat web应用程序并休息webservice 当我插入数据时，我得到例外！

我的班级CustomerProxy：

package com.rayanen.java.se.cmsd.proxy;

import com.rayanen.java.se.cmsd.dto.CustomerDTO;
import org.springframework.http.HttpEntity;
import org.springframework.http.HttpHeaders;
import org.springframework.http.HttpMethod;
import org.springframework.http.ResponseEntity;
import org.springframework.stereotype.Component;
import org.springframework.web.client.RestTemplate;

import javax.faces.context.FacesContext;

@Component
public class CustomerProxy implements ICustomerProxy{



    @Override
    public void insertCustomer(CustomerDTO customerDTO) {
        RestTemplate restTemplate = new RestTemplate();

        HttpHeaders requestHeaders = new HttpHeaders();

        String headerValue = FacesContext.getCurrentInstance().getExternalContext().getRequestHeaderMap().get("cookie");
        requestHeaders.add("Cookie", headerValue);

        HttpEntity requestEntity = new HttpEntity(customerDTO, requestHeaders);
        ResponseEntity response = restTemplate.exchange(
                "http://localhost:8080/ws/customer/insert",
                HttpMethod.POST,
                requestEntity,
                CustomerDTO.class);
        /*return response.getBody();*/
    }
}

class CustomerRestController：

package com.rayanen.java.se.cmsd.ws;

import com.rayanen.java.se.cmsd.dto.CustomerDTO;
import com.rayanen.java.se.cmsd.exceptions.*;
import com.rayanen.java.se.cmsd.facade.facadeimpl.CustomerFacade;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
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
@RequestMapping(value = "/customer")
public class CustomerRestController {
    @Autowired
    private CustomerFacade customerFacade;

    @RequestMapping(method = RequestMethod.POST, value = "/insert")
    ResponseEntity insert(@RequestBody CustomerDTO customerDTO){
        try {
            customerFacade.save(customerDTO);
        } catch (StoreFailedException e) {
            e.printStackTrace();
        } catch (CustomerIDDuplicateException e) {
            e.printStackTrace();
        } catch (EmailNotValidException e) {
            e.printStackTrace();
        } catch (CustomerIDNotValidExeption customerIDNotValidExeption) {
            customerIDNotValidExeption.printStackTrace();
        } catch (LastNameNotValidException e) {
            e.printStackTrace();
        } catch (NameNotValidException e) {
            e.printStackTrace();
        }
        return new ResponseEntity(HttpStatus.OK);
    }

}

class CustomerBean：

package com.rayanen.java.se.cmsd.webui;

import com.rayanen.java.se.cmsd.dto.CustomerDTO;
import com.rayanen.java.se.cmsd.exceptions.*;
import com.rayanen.java.se.cmsd.facade.facadeimpl.CustomerFacade;
import com.rayanen.java.se.cmsd.proxy.ICustomerProxy;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Component;

import javax.faces.application.FacesMessage;
import javax.faces.context.FacesContext;
import javax.faces.event.ActionEvent;
import java.io.Serializable;

@Component
@Scope("view")
public class CustomerBean implements Serializable{


    private CustomerDTO customerDTO = new CustomerDTO();
    private String lable;

    @Autowired
    private CustomerFacade customerFacade;

    @Autowired
    private ICustomerProxy iCustomerProxy;

    public String getLable() {
        return lable;
    }

    public void setLable(String lable) {
        this.lable = lable;
    }

    public CustomerDTO getCustomerDTO() {
        return customerDTO;
    }

    public void setCustomerDTO(CustomerDTO customerDTO) {
        this.customerDTO = customerDTO;
    }

    public void insert(ActionEvent actionEvent){
        lable = customerDTO.getName() + "; " + customerDTO.getLastName();
        iCustomerProxy.insertCustomer(customerDTO);
        FacesContext.getCurrentInstance().addMessage(null, new FacesMessage(FacesMessage.SEVERITY_INFO, "Added Successfully", ""));

    }



}

和插入我调试和查找异常的数据后的Exeption是这样的：

RestTemplate restTemplate = new RestTemplate();

Answer 1

是的，正如@Kayaman在评论中指出的那样，添加spring core依赖应该解决它。

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-core</artifactId>
        <version>5.0.2.RELEASE</version>
    </dependency>

Answer 2

问题出在我的其他依赖版本上我改变了它们并解决了问题

无法从spring-web
