错误：org.springframework.web.HttpMediaTypeNotSupportedException：内容类型'text /plain; charset = UTF

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)@ResponseBodypublic 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

text/plain
