我无法连接所有允许从 ajax 客户端发送的 xml 被解组为 Java 对象的部分。我将 Jquery 用于 ajax 客户端、Spring3 和 JAXB。以下是关键组件:
Ajax 客户端
        function checkForNewActivities(activities) {
            $j.ajax({
                url: "upload/checkForNewActivities",
                type: "POST",
                async: true, 
                dataType: "xml",
                data: ({activities:activities}),
                contentType: "application/xml",
                beforeSend: function() {
                    alert("sending ajax");
                },
                complete: function() {
                    alert("ajax sent");
                },
                success: function(data) {
                    alert("success");
                },
                error: function(jqXHR, textStatus, errorThrown) {
                    alert(textStatus + errorThrown);
                }
            });
        }
弹簧配置
<bean id="marshallingConverter" class="org.springframework.http.converter.xml.MarshallingHttpMessageConverter">
          <property name="marshaller" ref="jaxbMarshaller" />
          <property name="unmarshaller" ref="jaxbMarshaller" />
          <property name="supportedMediaTypes" value="application/xml"/>
    </bean>
<bean id="jaxbMarshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
    <property name="classesToBeBound">
        <list>
           a bunch of java classes
        </list>
    </property>
</bean>
这是作为目标的 Spring Controller 方法:
  @RequestMapping(value="/checkForNewActivities",headers="application/xml", method=RequestMethod.POST)
  public @ResponseBody String uploadMultipleWorkouts(@RequestBody String activities) {        
      System.out.println(activities);
      return ""; 
  }
使用 RequestMapping 中的 headers="application/xml",这个方法永远不会被调用。如果我删除标头参数,则调用该方法并将活动转储到控制台显示转义的 xml。
我显然错过了如何将此方法连接到 spring 配置,以便进行 xml 解组。
