ContextValueFilter

wenshao edited this page Apr 18, 2016 · 6 revisions

在某些场景下,对Value做过滤,需要获得所属JavaBean的信息,包括类型、字段、方法等。在fastjson-1.2.9中,提供了ContextValueFilter,类似于之前版本提供的ValueFilter,只是多了SeriliazeContext参数可用。

package com.alibaba.fastjson.serializer;

public interface ContextValueFilter extends SerializeFilter {
    Object process(SerializeContext context, 
                   Object object, 
                   String name, 
                   Object value);
}

其中SerializeContext的定义如下:

package com.alibaba.fastjson.serializer;

public final class SerializeContext {
    public Class<?> getBeanClass();

    public Method getMethod();

    public Field getField();

    public String getName();

    public String getLabel();
}
