FastJson可以把读取到的数据直接解析为对象即可，所以，你可需求知道json的数据格式，然后根据格式定制beanv即可，闲话少说，直接上代码
1. bean如下所示
package com.json.example;
import java.io.Serializable;
import java.util.List;
public class Bean implements Serializable
{
private static final long serialVersionUID = -7722646761436254605L;
private int beginPage;
private int cacheSize;
private int total;
private List<?> data;
public int getTotal()
{
return total;
}
public void setTotal(int total)
{
this.total = total;
}
public int getBeginPage()
{
return beginPage;
}
public void setBeginPage(int beginPage)
{
this.beginPage = beginPage;
}
public int getCacheSize()
{
return cacheSize;
}
public void setCacheSize(int cacheSize)
{
this.cacheSize = cacheSize;
}
public List<?> getData()
{
return data;
}
public void setData(List<?> data)
{
this.data = data;
}
@Override
public String toString()
{
return "Bean [beginPage=" + beginPage + ",cacheSize=" + cacheSize
+ ",total=" + total + ",data=" + data + "]";
}
}
2. 原json格式：

解析代码如下：
<pre class="java" name="code">public class JsonParse
{
public static void main(String[] args) throws Exception
{
String jsonString = ClientAbortMethod.getJsonString(null);
String strAfter = jsonString.substring(2,jsonString.length() - 4);
System.out.println(strAfter);
Bean obj = JSON.parSEObject(strAfter,Bean.class);
System.out.println(obj);
