集成Spring MVC，Jquery，Ajax和Tiles

I'm trying to implement an ajax functionality into my weapp, I'm using Spring MVC and Tiles, for Ajax call I'm using jquery.

我正在尝试在我的weapp中实现ajax功能,我正在使用Spring MVC和Tiles,对于Ajax调用我正在使用jquery。

Everything works fine except ajax functionality

除了ajax功能外,一切正常

相关代码如下:

Tiles Configuration:

<beans:bean class="org.springframework.js.ajax.AjaxUrlBasedViewResolver" id="tilesViewResolver">
        <beans:property name="viewClass" value="org.springframework.js.ajax.tiles2.AjaxTilesView"/>
    </beans:bean>

<beans:bean class="org.springframework.web.servlet.view.tiles2.TilesConfigurer" id="tilesConfigurer">
    <beans:property name="definitions">
        <beans:list>
            <beans:value>/WEB-INF/plantilla/plantilla.xml</beans:value>
            <!-- Scan views directory for Tiles configurations -->
            <beans:value>/WEB-INF/views/**/vistas.xml</beans:value>
        </beans:list>
    </beans:property>
</beans:bean>

My Controller:

@RequestMapping(value = "clientes/listarProvincias", method = RequestMethod.GET,headers="Accept=*/*")
public @ResponseBody List<Provincia> listarProvincias(@RequestParam(value = "departamento", required = true)String codigoDepartamento){
    logger.info("Ingresando al Metodo Listar Provincias con Ajax");
    Integer codDep = Integer.parseInt(codigoDepartamento);
    return this.provinciaDAO.listarProvinciaPorDepartamento(codDep);
}

My JSP

   <script type="text/javascript">
$(document).ready(function() { 
    $('#departamento').change(
            function() {
                $.getJSON('clientes/listarProvincias', {
                    departamento : $(this).val(),
                    ajax : 'true'
                }, function(data) {
                    alert("Ingresando a JSON");
                    var html = '<option value="">Departamento</option>';
                    var len = data.length;
                    for ( var i = 0; i < len; i++) {
                        html += '<option value="' + data[i].name + '">'
                                + data[i].name + '</option>';
                    }
                    html += '</option>';

                    $('#provincias').html(html);
                });
            });
});
</script>

Part of the form

部分表格

 <p>
                        <label>Departamento</label>
                        <span class="field">
                            <form:select path="departamento.codDpto" id="departamento">

                                <c:forEach items="${departamentos}" var="departamento">
                                    <form:option value="${departamento.codDpto}">${departamento.descripcion}</form:option>
                                </c:forEach>
                            </form:select>
                            <label class="error">

                            </label>
                        </span>
                    </p>

                    <p>
                        <label>Provincia</label>
                        <span class="field">
                            <form:select path="provincia.codprovincia" id="provincias">
                                <form:option value="" ></form:option>
                                <c:forEach items="${provincias}" var="provincia">

                                </c:forEach>
                            </form:select>
                            <label class="error">
                                <form:errors path="estaReg" cssClass="error"></form:errors>
                            </label>

I don't know what I'm doing wrong. Best Regards,

Check if you need change your controller declaration as well

检查您是否还需要更改控制器声明

  @RequestMapping(value = "json", headers = "Accept=application/json")
    @ResponseBody
    public ResponseEntity<java.lang.String> listJson(@RequestParam String nombre) {
        HttpHeaders headers = new HttpHeaders();

        // PAY ATTENTION TO THIS:
        headers.add("Content-Type", "application/json; charset=utf-8");

        List<Medico> result = null;
        if (org.apache.commons.lang3.StringUtils.isEmpty(nombre)) {
            result = Provincia.findProvinciaEntries(0, 10);
        } else result = Provincia.findProvinciaEntries(0, 10);


        // NEED TO CREATE JSON ARRAY
        String data = "{\"items\":" + Provincia.toJsonArray(result) + " }";
        return new ResponseEntity<String>(data, headers, HttpStatus.OK);
    }

Hope this help you
