Question

我正在使用Spring MVC 3来设置和处理表单，但是我遇到了这个问题，这是我在使用Spring MVC 3提交表单时从未遇到的问题，我无法理解其背后的原因。

当我提交表单时，我得到 HTTP状态405 - 请求方法'POST'不支持错误。以下是我用来实现它的.jsp表单和控制器。

newProblem.jsp

<form:form  commandName="problem" >
        <form:label path="problem" >
            <span class="label">Problem <form:errors path="problem" /></span>
        </form:label>
        <form:textarea path="problem" cssClass="editor"  id="editor"/>


        <input type="submit" value="create"  />
</form:form>

ProblemManagementController.java

//Add new problem (GET)
@RequestMapping(method=RequestMethod.GET, value="/admin/problems/new")
public String setUpForm(Model model) {
    model.addAttribute("problem", new Problem());
    return "newProblem";
}

//Add new problem (POST)
@RequestMapping(method=RequestMethod.POST, value="/admin/problems/new")
public String processForm(@Valid Problem problem, Errors result) {
    if(result.hasErrors()) {
        return "newProblem";
    }
    problemManagementService.createProblem(problem);
    return "redirect:/admin/problems";
}

//Display all problems
@RequestMapping(value="/admin/problems")
public String displayAllProblems(Model model) {
    List<Problem> allProblems = problemManagementService.getAllProblems();

    model.addAttribute("allProblems", allProblems);
    return "allProblems";
}

有人可以帮我理解为什么会收到此错误？

您忘记在<form:form>代码中添加操作。

试试这个：

<form:form action="admin/problems/new" commandName="problem" >
        <form:label path="problem" >
            <span class="label">Problem <form:errors path="problem" /></span>
        </form:label>
        <form:textarea path="problem" cssClass="editor"  id="editor"/>


        <input type="submit" value="create"  />
</form:form>
