我收到一个奇怪的错误，我看不出原因...因为它所说的无法找到的ID位于URL：http://192.168.160.128:8080/deleteproposal/4并且我有类似的requestMethod工作正常......
异常：org.springframework.web.bind.MissingServletRequestParameterException：必需长参数'id'不存在 网址失败：http://192.168.160.128:8080/deleteproposal/4 异常消息：必需长参数'id'不存在

控制器还没有做任何事......
@RequestMapping(value="/deleteproposal/{id}", method=RequestMethod.GET)
public ModelAndView deleteProposal(ModelAndView modelAndView, @RequestParam(value ="id") Long id) {
System.out.println("!!!!: PROPOSAL CONTROLLER: DELETE id : ");
return modelAndView;
}
jsp是正常的......
<c:forEach var="proposal" items="${allproposals}">
<tr>
<td>${proposal.id}</td>
<td><span class="label label-warning">${proposal.proposalType}</span></td>
<td class="hidden-sm">
<a href="${contextRoot}/viewonestatus/${proposal.statusUpdate.id}">${proposal.functionality}</a>
</td>
<td><fmt:formatDate pattern="EEEE',' d ' de ' MMMM ' de 'y" value="${proposal.release}" /></td>
<td>
<a href="${contextRoot}/deleteproposal/${proposal.id}">
<button class="btn-u" type="button" >Borrar</button>
</a>
</td>
<td>
<a href="${contextRoot}/assignonevotes/${proposal.id}">
<button class="btn-u" type="button">Modificar</button>
</a>
</td>
</tr>
</c:forEach>
答案 0 :(得分：3)
要将方法参数名称与URI模板变量（/ deleteproposal / {id}）名称匹配，请使用@PathVariable(value="id")代替@RequestParam(value ="id")
