const app=require('express')();
const opt={
  application:{name:'fxxk'},
  register:'www.cctv.com:2181',
  dubboVer:'2.5.3.6',
  root:'dubbo',
  dependencies:{
    Foo:{
      interface:'com.service.Foo',
      version:'LATEST',
      timeout:6000,
      group:'isis',
      methodSignature: {
        findById = (id) => [ {'$class': 'java.lang.Long', '$': id} ],
        findByName = (name) => (java) => [ java.String(name) ],
      }
    },
    Bar:{
      interface:'com.service.Bar',
      version:'LATEST',
      timeout:6000,
      group:'gcd'
    }
  }  
}
opt.java = require('js-to-java')

const Dubbo=new nzd(opt);

const customerObj = {
  $class: 'com.xxx.XXXDTO',
  $: {
    a: 1,
    b: 'test',
    c: {$class: 'java.lang.Long', $: 123}
  }
};

app.get('/foo',(req,res)=>{
  Dubbo.Foo
    .xxMethod({'$class': 'java.lang.Long', '$': '10000000'},customerObj)
    .then(data=>res.send(data))
    .catch(err=>res.send(err))
})

app.get('/foo/findById',(req,res)=>{
  Dubbo.Foo
    .findById(10000)
    .then(data=>res.send(data))
    .catch(err=>res.send(err))
})

app.listen(9090)



```
### 注意

须等待初始化完毕才能正常使用，标志：**Dubbo service init done**

如果要和1.x版本共存的话试试这个，[niv](https://github.com/scott113341/npm-install-version).
