使用与不适用@RequestBody注解的区别

1.
如果使用@RequestBody接受页面参数：
public Map<String,Object> insertBudget(@ApiParam(required = true,name = "actBudgetCost",value = "预算")@RequestBody ActBudgetCost actBudgetCost, HttpServletRequest request){

}

那么前台页面ajax应该这样写：
$.ajax({
url: '',
type: "POST",
data: JSON.stringify({
"actiName":name
}),
dataType: "json",
contentType: "application/json",
async: false,
success: function (result) {

},
error: function (xhr, ajaxOptions, thrownError) {
//console.log(thrownError); //alert any HTTP error
//alert("请求出错！");
return false;
}
});

2.
如果不使用@RequestBody接受页面参数：
public Map<String, Object> regProduct(HttpServletRequest request,
@ApiParam(name = "customerProAuditPO", value = "产品注册实体")CustomerProAuditVO customerProAuditVO
) {

}

那么前台页面ajax应该这样写：
var data = {
customerName:customerName,
};
$.ajax({
url:'',
type: "POST",
data: data,
//async: false,
dataType:"json",
success: function(result) {
var json = result;

},
error: function (xhr, ajaxOptions, thrownError) {
console.log(thrownError);
return false;
}
});
