Fabric2.3.0 基于maven安装java智能合约

官方案例地址： https://github.com/hyperledger/fabric-chaincode-java/tree/master/examples/fabric-contract-example-maven ，这个案例无法直接使用 。

我们知道老版本是将智能合约实现ChaincodeBase 然后 在pom文件的mainClass 里面 写入智能合约引用 。 2.0版本略有不同 你只需要实现

ContractInterface接口然后在pom文件的mainClass 里面 写入org.hyperledger.fabric.contract.ContractRouter 即可 注意不是 你开发的做能合约引用 ，而且 只要在你的方法里面加上
@Transaction 注解 就不再需要像以前一样在Invoke里面各种判断方法名了。
java maven 形式的智能合约安装很慢，是因为每次安装的时候都会从maven仓库去下载依赖，我们可以在pom.xml里面修改仓库地址
