java - 错误 : org. springframework.web.HttpMediaTypeNotSupportedException:不支持内容类型 'text/plain;charset=UTF-8'

Question

我是 Spring Data 的新手。我不断收到错误:org.springframework.web.HttpMediaTypeNotSupportedException: Content type 'text/plain;charset=UTF-8' not supported我试图将 @RequestMapping 注释中的消耗更改为 text/plain 但不幸的是它没有帮助。*

有什么想法吗？

谢谢，

我的代码如下所示:

package com.budget.processing.application;


import com.budget.business.service.Budget;
import com.budget.business.service.BudgetItem;
import com.budget.business.service.BudgetService;
import com.budget.processing.dto.BudgetDTO;
import com.budget.processing.dto.BudgetPerConsumerDTO;
import com.utils.Constants;
import com.common.utils.config.exception.GeneralException;
import org.apache.log4j.Logger;
import org.joda.time.YearMonth;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;
import org.springframework.web.bind.annotation.*;

import javax.ws.rs.core.MediaType;
import java.text.ParseException;
import java.util.ArrayList;
import java.util.Collection;
import java.util.List;


@Controller("budgetManager")
@RequestMapping(value = "budget", produces  = Constants.RESPONSE_APP_JSON)
@Transactional(propagation = Propagation.REQUIRED)
public class BudgetManager {

private static final Logger logger = Logger.getLogger(BudgetManager.class);


@Autowired
private BudgetService budgetService;


@RequestMapping(method = RequestMethod.GET)
public
@ResponseBody
Collection<BudgetDTO> getBudgetMonthlyAllConsumers() throws GeneralException {

    List<Budget> budgetList = budgetService.getBudgetForAllConsumers();
    List<BudgetDTO> bugetDtos = new ArrayList<>();
    for (Budget budget : budgetList) {
        BudgetDTO budgetDTO = generateBudgetDto(budget);
        bugetDtos.add(budgetDTO);
    }
    return bugetDtos;
}


@RequestMapping(method = RequestMethod.PUT, consumes = MediaType.APPLICATION_JSON)
public
@ResponseBody
Collection<BudgetDTO> updateConsumerBudget(@RequestParam(value = "budgetPerDate", required = false)

                          ArrayList<BudgetPerConsumerDTO> budgetPerDate) throws GeneralException, ParseException {

    List<BudgetItem> budgetItemList = new ArrayList<>();
    List<Budget> budgets = new ArrayList<>();
    if (budgetPerDate != null) {
        for (BudgetPerConsumerDTO budgetPerConsumerDTO : budgetPerDate) {
            budgetItemList.add(budgetService.createBudgetItemForConsumer(budgetPerConsumerDTO.getId(), new YearMonth(budgetPerConsumerDTO.getDate()), budgetPerConsumerDTO.getBudget()));
        }
    }

    budgets = budgetService.getBudgetForAllConsumers();
    List<BudgetDTO> budgetDTOList = new ArrayList<>();
    for (Budget budget : budgets) {
        BudgetDTO budgetDto = generateBudgetDto(budget);
        budgetDTOList.add(budgetDto);
    }
    return budgetDTOList;

}

}

这是我得到的异常(exception):

Answer 1

根据评论中提到的内容，最简单的解决方案是:

@RequestMapping(method = RequestMethod.PUT, consumes = MediaType.APPLICATION_JSON_VALUE)
@ResponseBody
public Collection<BudgetDTO> updateConsumerBudget(@RequestBody SomeDto someDto) throws GeneralException, ParseException {

    //whatever

}

class SomeDto {

   private List<WhateverBudgerPerDateDTO> budgetPerDate;


  //getters setters
}

该解决方案假定您正在创建的 HTTP 请求实际上具有

Content-Type:application/json 而不是 text/plain
