SpringMVC---400错误The request sent by the client was syntactically incorrect ()
在SpringMVC中使用@RequestBody和@ModelAttribute注解时遇到了很多问题,现记录下来。
@ModelAttribute这个注解主要是将客户端请求的参数绑定参数到一个对象上,不用将很多参数@RequestParam或是@PathVariable。
但是在使用过程中遇到了问题,
第一次Html端请求代码如下,请求方式1
// 简单键值对
var data = {
productTypeIds : vproducttypeid,
channelTypeId : vchanneltypeid,
userId : 1,
}; // 提交保存
$.ajax({
"type" : "POST",
"url" : chainelUtil.URL.ACTION_IMPORT,
"data" : data,
"success" : function(data) {
bootbox.alertTimeout("创建成功!");
},
"error" : function(data) {
bootbox.alertTimeout("创建失败!");
}
});
Controller代码如下:
@RequestMapping(value = "/importstorestore", method = RequestMethod.POST)
@ResponseBody
public Object importStoreToStoreTree(@ModelAttribute StoreStoreRelationVO storeRelationVO ) {
}
StoreStoreRelationVO代码如下:
@Component
public class StoreStoreRelationVO implements Serializable{ /**
*
*/
private static final long serialVersionUID = 1L; // 渠道关系实体
private StoreStoreEntity storeStoreEntity; // 渠道类型Id
private String channelTypeId; // 商品分类Id字符串以","分割
private String productTypeIds; // 商品分类Id List
private List<String> productTypeIdList; // 区域Id,目前版本可能用不上
private String regionId; // 当前登陆用户
private String userId;
// 省略getter setter
}
StoreStoreEntity如下:
@Entity
@Table(name = "base_store_store")
public class StoreStoreEntity implements Serializable{ /**
*
*/
private static final long serialVersionUID = 1L; @Id
@Column
@GenericGenerator(name = "idGenerator", strategy = "increment")
@GeneratedValue(generator = "idGenerator")
private Long id; // 上级id
private Long upstoreid; // 下级id
private Long downstoreid; // 所属渠道id
private Long channelid;
// 省略getter 和 setter
}
如上的请求没问,服务器端可以接受到数据。
但是如果将请求的参数修改为如下,对象中组合对象,因为StoreStoreRelationVO 有个属性是StoreStoreEntity
// StoreStoreEntity
var storeStore = {
upstoreid : vupstoreid,
downstoreid:vcurrentstoreid,
channelid:1,
};
// StoreStoreRelationVO
var data = {
storeStoreEntity:storeStore,
productTypeIds : vproducttypeid,
channelTypeId : vchanneltypeid,
userId : 1,
};
如果用请求方式1请求,直接报错
HTTP Status 404 -
type Status report
message
description The requested resource is not available.
Apache Tomcat/7.0.52
我将Ajax请求参数改为Json,如下,请求方式2
// 提交保存
$.ajax({
"type" : "POST",
"dataType" : 'json',
"contentType" : "application/json;charset=UTF-8",
"url" : chainelUtil.URL.ACTION_IMPORT,"data" : JSON.stringify(data),
"success" : function(data) {
var messagetext = $('#message');
messagetext.html("已经向系统成功提交申请,创建成功!");
bootbox.alertTimeout("创建成功!");
},
"error" : function(data) {
var messagetext = $('#message');
messagetext.html("服务器繁忙,请重新提交!");
bootbox.alertTimeout("创建失败!");
}
});
服务器端不变,这样不报错了,但是storeRelationVO却接收不到数据,不能自动装载。
我将Controller中的@ModelAttribute修改为@RequestBody
storeRelationVO可以正常接受到数据。
----------------------------------------------------------------------
为什么Json就能正确成功呢,我又将Ajax改回到最初格式,参数格式不设定
$.ajax({
"type" : "POST",
"url" : chainelUtil.URL.ACTION_IMPORT,
"data" : data,
"success" : function(data) {
bootbox.alertTimeout("创建成功!");
},
"error" : function(data) {
bootbox.alertTimeout("创建失败!");
}
});
结果不出所料,报错,415 Unsupported Media Type
HTTP Status 415 -
type Status report
message
description The server refused this request because the request entity is in a format not supported by the requested resource for the requested method.
Apache Tomcat/7.0.52
看来用@RequestBody,需要传Json数据
----------------------------------
我将请求参数稍微改了一下,其余不变
var storeStore = {
upstoreid : vupstoreid,
downstoreid:vcurrentstoreid,
channelid:1,
};
var data = {
storeStoreEntity:storeStore,
productTypeIds : vproducttypeid,
channelTypeId : vchanneltypeid,
userid : 1,
};
结果报错,这个错我找了好久啊,最后发现一个大小写错误,userid应该对应实体中的userId,一个i应该是大写,所以请求参数不区分大小写!
HTTP Status 400 -
type Status report
message
