Question

我正在使用spring mvc和mysql，我的问题是，当我使用spring的form标签保存数据时，编码包括像“à，á，é，ã”这样的字母，当我将这些数据从数据库返回到输入字段时，但是当我合并新数据时，编码后的字符无法通过UTF-8到达控制器，控制器会重新使用“CombustÃ£o”而不是“Combustão”

这是我的表格：

<form action="${pageContext.request.contextPath}/catalog/carro/saveedit"
                  method="post">
                <div class="form-group">
                    <label class="col-md-4" for="nome">Carro:</label>
                    <input class="form-control" type="text" name="nome"
                           id="nome" value="${carroEditable.nome}"/>
                </div>
                <div class="form-group">
                    <label for="categoria" class="col-md-4">Categoria:</label>
                    <select name="categoria" id="categoria"
                            class="form-control">
                        <option selected value="${carroEditable.categoria}">
                            ${carroEditable.categoria}
                        </option>
                        <option value="Combustão">Combustão</option>
                        <option value="Elétrico">Elétrico</option>
                    </select>
                </div>
                <div class="form-group">
                    <button type="submit" class="btn btn-default btn-block">
                        Salvar
                    </button>
                </div>
                <input type="hidden" name="idCarro"
                       value="${carroEditable.idCarro}"/>
            </form>

和我的控制器

 @RequestMapping(value = "/catalog/carro/saveedit",
            method = RequestMethod.POST)
    public String merge(ServletRequest request)
            throws ServletRequestBindingException, UnsupportedEncodingException {



        Integer id = ServletRequestUtils.getIntParameter(request, "idCarro");
        String categoria = ServletRequestUtils.getRequiredStringParameter
                (request,
                        "categoria");
        String nome = ServletRequestUtils.getRequiredStringParameter(request,
                "nome");
        Carros carros = carrosRepository.findOne(id);
        carros.setNome(nome);
        carros.setCategoria(categoria);
        carrosRepository.saveAndFlush(carros);
        return "redirect:/catalog/carro/gerencia";

我也试过

 <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

表格标签

content="text/html; charset=UTF-8"

尝试将spring CharacterEncodingFilter添加到您的web.xml。

  <filter>
    <filter-name>encodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
      <param-name>encoding</param-name>
      <param-value>UTF-8</param-value>
    </init-param>
  </filter>
  <filter-mapping>
    <filter-name>encodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
