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

SpringMVC---400错误The request sent by the client was 
syntactically incorrect ()
// 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!");
    }
});
SpringMVC---400错误The request sent by the client was 
syntactically incorrect ()

Controller代码如下:

@RequestMapping(value = "/importstorestore", method = RequestMethod.POST)
    @ResponseBody
    public Object importStoreToStoreTree(@ModelAttribute StoreStoreRelationVO storeRelationVO ) {
}

StoreStoreRelationVO代码如下:

SpringMVC---400错误The request sent by the client was 
syntactically incorrect ()
@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
}
SpringMVC---400错误The request sent by the client was 
syntactically incorrect ()

StoreStoreEntity如下:

SpringMVC---400错误The request sent by the client was 
syntactically incorrect ()
@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
}
SpringMVC---400错误The request sent by the client was 
syntactically incorrect ()

 

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

SpringMVC---400错误The request sent by the client was 
syntactically incorrect ()
// StoreStoreEntity
var
storeStore = { upstoreid : vupstoreid, downstoreid:vcurrentstoreid, channelid:1, }; // StoreStoreRelationVO  var data = { storeStoreEntity:storeStore, productTypeIds : vproducttypeid, channelTypeId : vchanneltypeid, userId : 1, };
SpringMVC---400错误The request sent by the client was 
syntactically incorrect ()

 

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

SpringMVC---400错误The request sent by the client was 
syntactically incorrect ()
// 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!");
    }
});
SpringMVC---400错误The request sent by the client was 
syntactically incorrect ()

 

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

SpringMVC---400错误The request sent by the client was 
syntactically incorrect ()
$.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!");
    }
});
SpringMVC---400错误The request sent by the client was 
syntactically incorrect ()

 

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

SpringMVC---400错误The request sent by the client was 
syntactically incorrect ()
var storeStore = {
            upstoreid : vupstoreid,
            downstoreid:vcurrentstoreid,
            channelid:1,
    };
    
    var data = {
            storeStoreEntity:storeStore,
            productTypeIds : vproducttypeid,
            channelTypeId : vchanneltypeid,
            userid : 1,
    };
SpringMVC---400错误The request sent by the client was 
syntactically incorrect ()

 

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 -
