Action代码如下：

package controller;

import com.opensymphony.xwork2.ActionSupport;

import net.sf.json.JSONObject;

public class GetJSON extends ActionSupport{

private String jsonString;

public String getJsonString(){

return this.jsonString;

}

public void setJsonString(String jsonString){

this.jsonString = jsonString;

}

@Override

public String execute() throws Exception {

System.out.println(jsonString);

JSONObject json = JSONObject.fromObject(jsonString);

System.out.println("username=" + json.get("username"));

System.out.println("password=" + json.get("password"));

System.out.println("age=" + json.get("age"));

System.out.println("BigText=" + json.get("BigText"));

return null;

}
