sofa-hessian-node
蚂蚁金服对 Hessian 序列化的定制版本
sofa-hessian-node 对应的 Java Hessian 版本是 v3.1.3。它对 hessian.js-1 模块做了进一步封装,通过预编译来提高性能。
安装
$ npm install sofa-hessian-node --save
示例
'use strict';
// classMap 是要序列化类的定义
const classMap = {
'com.alipay.test.sub.TestObj2': {
name: {
type: 'java.lang.String',
},
transientField: {
type: 'java.lang.String',
isTransient: true,
},
finalField: {
type: 'java.lang.String',
defaultValue: 'xxx',
},
staticField: {
type: 'java.lang.String',
isStatic: true,
},
},
};
const encode = require('sofa-hessian-node').encode;
const buf = encode({
$class: 'com.alipay.test.sub.TestObj2',
$: { name: 'gxcsoccer' },
}, '2.0', classMap);
console.log(buf.toString('hex'));

hessian 4 支持
const { v4 } = require('sofa-hessian-node');
const buf = v4.encode({
$class: 'com.alipay.test.sub.TestObj2',
$: { name: 'gxcsoccer' },
}, '2.0', classMap);
console.log(buf.toString('hex'));
性能数据
从 benchmark 看,相比于直接使用 hessian.js-1,sofa-hessian-node 性能有非常明显的提高(特别是针对复杂对象的场景)
