struts.xml
entry struts.xml
条目中有一个拼写错误 struts.xml
. struts.xml
定义tile结果和拦截器。 Please see this link data
key. data
密钥。 So it will be always null. Approach 1. 方法1。
Create setters for lists,maps,number1,numberarray1,string1
and so on. 为
lists,maps,number1,numberarray1,string1
等创建setter。 In the top of this link , is defined the way to do it. 在此链接的顶部,定义了执行此操作的方式。 Then you can access all the variables in this way.
然后,您可以通过这种方式访问所有变量。
Approach 2. In your javascript define a new object. 方法2.在你的javascript中定义一个新对象。
var sentData ={};
sentData ["sentData "] = data;
// And in your ajax call ,
data: JSON.stringify(sentData),
And in your action class, create getters and setters for this. 在你的动作类中,为此创建getter和setter。
Map<K.V> sentData = new HashMap<K,V>();
This will give you whole json object as a Map. 这将为您提供整个json对象作为Map。
