Question

我有问题，我真的需要帮助。我试图从jsp发布到控制器2的数据只有1个ajax帖子。

我的Ajax：

$.ajax({
        type: "POST",
        url: contextPath + "/generalLedger/journalEntries/form",
        data : {"json" : glEntries, "searchParam" : searchData},
        success: function(data) {
            alert("Success!!!");
        },
        error: function (jqXHR, textStatus, errorThrown) {
            alert(jqXHR + " : " + textStatus + " : " + errorThrown);
        }
});

在我的控制器中：

@RequestMapping (method = RequestMethod.POST,  value = "/form")
public String postJournalEntry (@RequestBody String json, @RequestBody String searchParam, Model model) {
    // Some codes here
}

我的问题是我有：

Answer 1

在jquery代码行中，

data : {"json" : glEntries, "searchParam" : searchData},

应该是，

data : {json : glEntries, searchParam : searchData},

使用ajax发布2个数据
