如果我对您的理解正确，则可以执行以下操作（我使用的是Spring 3.2.3.RELEASE＆Jackson 1.9.12）。
在applicationContext.xml中，您具有：
<bean id="jacksonMessageConverter" /> <bean > <property name="messageConverters"> <list> <ref bean="jacksonMessageConverter"/> </list> </property> </bean>
您具有如下所示的Spring控制器：
package test;import org.apache.log4j.Logger;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestBody;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestMethod;import org.springframework.web.bind.annotation.ResponseBody;@Controller@RequestMapping("/json")public class JsonParsingController { private final static Logger log = Logger.getLogger(JsonParsingController.class); @RequestMapping(value = "/cart.do", method = RequestMethod.POST, produces = "application/json; charset=utf-8")@ResponseBody public CartResponse handleCart(@RequestBody Cart cart) { if (cart != null) { log.debug(cart); } return new CartResponse("OK!");}}和三个POJO：
package test;public class Cart { private String id; private Checkout checkoutID; public String getId() { return id; } public void setId(String id) { this.id = id; } public Checkout getCheckoutID() { return checkoutID; } public void setCheckoutID(Checkout checkoutID) { this.checkoutID = checkoutID; } @Override public String toString() { return "Cart{" + "id='" + id + ''' + ", checkoutID=" + checkoutID + '}'; }}package test;public class Checkout { private String id; private String billingAddress; private String shippingAddress; public String getId() { return id; } public void setId(String id) { this.id = id; } public String getBillingAddress() { return billingAddress; } public void setBillingAddress(String billingAddress) { this.billingAddress = billingAddress; } public String getShippingAddress() { return shippingAddress; } public void setShippingAddress(String shippingAddress) { this.shippingAddress = shippingAddress; } @Override public String toString() { return "Checkout{" + "id='" + id + ''' + ", billingAddress='" + billingAddress + ''' + ", shippingAddress='" + shippingAddress + ''' + '}'; }}package test;public class CartResponse { private String result; public CartResponse(String result) { this.result = result; } public String getResult() { return result; } public void setResult(String result) { this.result = result; }}然后，您可以在HTML页面中执行以下操作：
<script language="Javascript" type="text/javascript"> $(document).ready(function () { // Your data var arr = { id: '51f631cb84812abb04000006', checkoutID: { id: '123456789', "shippingAddress" : "5h avenue - new york", "billingAddress" : "5h avenue - new york" } }; $.ajax({ url: '/json/cart.do', type: 'POST', data: JSON.stringify(arr), contentType: 'application/json; charset=utf-8', dataType: 'json', async: false, success: function (msg) { alert(msg.result); } }); });</script>至少对我来说-它有效:)
