如何将参数传递给Thymeleaf Ajax Fragment
我有一个Spring MVC控制器,该控制器返回百里香叶片段的名称以查看解析器bean。问题在于此片段需要使用url作为参数。在这里我放片段:
<!-- A fragment with wrapper form for basic personal information fragment --> <th:block th:fragment="form-basic(url)">
<form role="form" th:action="${url}" method="post" th:object="${user}">
<th:block th:replace="admin/fragments/alerts::form-errors"></th:block>
<th:block th:include="this::basic" th:remove="tag"/>
<div class="margiv-top-10">
<input type="submit" class="btn green-haze" value="Save" th:value="#{admin.user.form.save}" />
<input type="reset" class="btn default" value="Reset" th:value="#{admin.user.form.reset}" />
</div>
</form>
</th:block>
我无法在没有错误的情况下传递该参数。控制器如下:
@RequestMapping(method = RequestMethod.GET)public String show(@CurrentUser User user, Model model) {
logger.info(user.toString());
if(!model.containsAttribute(BINDING_RESULT_NAME)) {
model.addAttribute(ATTRIBUTE_NAME, user);
}
model.addAttribute("url", "/admin/users/self/profile");
return "admin/fragments/user/personal::form-basic({url})";
}
对于上面的示例,我得到以下错误:
06-Jan-2017 11:36:40.264 GRAVE [http-nio-8080-exec-9] org.apache.catalina.core.StandardWrapperValve.invoke El Servlet.service() para el servlet [dispatcher] en el contexto con ruta [/ejercicio3] lanzó la excepción [Request processing failed; nested exception is java.lang.IllegalArgumentException: Invalid template name specification: 'admin/fragments/user/personal::form-basic({url})'] con causa raíz java.lang.IllegalArgumentException: Invalid template name specification: 'admin/fragments/user/personal::form-basic({url})'

我已经做过这些测试:
"admin/fragments/user/personal::form-basic('{url}')";"admin/fragments/user/personal::form-basic(@{/admin/users/self/profile})";
"admin/fragments/user/personal::form-basic(/admin/users/self/profile)";
"admin/fragments/user/personal::form-basic('/admin/users/self/profile')";
总之我得到了错误
回答:
您可以通过两种方式将参数从控制器传递到Thymeleaf片段。首先是通常的Spring方式-抛出模型:
@RequestMapping(method = RequestMethod.GET)public String show(@CurrentUser User user, Model model) {
model.addAttribute("url", "/admin/users/self/profile");
return "admin/fragments/user/personal::form-basic";
}
够了 在这种情况下,您无需指定任何片段参数(即使您有)。
第二种方法是在片段名称中指定参数:
@RequestMapping(method = RequestMethod.GET)public String show(@CurrentUser User user, Model model) {
String url = "/admin/users/self/profile";
return String.format("admin/fragments/user/personal::form-basic(url='%s')",url);
}
注意,必须指定参数名称,并且字符串值必须放在单引号中。在这种情况下,您不需要url
在模型中添加变量。
