Fastjson writeJSONString方法
Fastjson在1.2.11版本中,JSON类新增对OutputStream/Writer直接支持。
package com.alibaba.fastjson; public abstract class JSON { public static final int writeJSONString(OutputStream os, // Object object, // SerializerFeature... features) throws IOException; public static final int writeJSONString(OutputStream os, // Charset charset, // Object object, // SerializerFeature... features) throws IOException; public static final int writeJSONString(Writer os, // Object object, // SerializerFeature... features) throws IOException; }
import com.alibaba.fastjson; import java.nio.charset.Charset; class Model { public int value; } Model model = new Model(); model.value = 1001; OutputStream os = ...; JSON.writeJSONString(os, model); JSON.writeJSONString(os, Charset.from("GB18030"), model); Writer writer = ...; JSON.writeJSONString(os, model);
