首先需要導包
commons-beanutils-1.7.0.jar
commons-collections-3.2.1.jar
commons-lang-2.3.jar
commons-lang3-3.1.jar
commons-logging-1.0.4.jar
後臺接受前臺需用set get方法

這是action
public class Action extends ActionSupport {
	private long num;
	private int type;
	String  documentType;

	public long getNum() {
		return num;
	}
	public void setNum(long num) {
		this.num = num;
	}
	public int getType() {
		return type;
	}
	public void setType(int type) {
		this.type = type;
	}
	public String show() throws IOException {
		Gson sGson = new Gson();
		JSONArray jsonArray = new JSONArray() ;
		for(int i=0;i<2;i++){
			Object[] objects = new Object[1];
			objects[0]=1;
			objects[1]=URLEncoder.encode("https://www.baidu.com/", "utf-8");//進行轉碼
			}
			jsonArray.add(objects);
		String json = sGson.toJson(jsonArray);
		ServletActionContext.getResponse().setContentType("text/html;charset=utf-8");
		ServletActionContext.getResponse().getWriter().write(json);
		System.out.println(num);
		System.out.println(type);
		return null;
	}
}

 

這是js前臺程式碼

 var params= $.param({
					'num' : 123,
					'type' : 456,
				}, true);
			$.ajax({
	            type : 'POST',
	            url : 'Action ',
	            async:true,
	            data :params,
				success : function(data) {
					  data =JSON.parse(data);
					  for ( var x in data) { 
					  data[x][1]=decodeURI(data[x][1], "utf-8");//解碼
						console.log(data);	
						}
	            },
	            error : function() {
	            	console.log("errpr");
	            }
	        });  
 

struts程式碼

<action name="Action " class="Action " method="show">
		</action>
