一、前言

上一篇文章介绍了spring boot集成thrift分别在jar和war的情况下启动thrift服务。从文章中可以发现，客户端获取的信息是在服务端固定的参数。如何处理我们的业务呢？这将是本篇文章的重点。话不多说直接开始... ...

二、项目整改

在springboot中要处理业务中的信息，需要获取项目中的上下文信息即可，具体操作如下：

• 2.1 修改thrift服务（ThriftServer）

 package cn.bintools.daios.example.thrift.server;

import cn.bintools.daios.example.thrift.HelloService;
import cn.bintools.daios.example.thrift.impl.HelloServiceImpl;
import lombok.extern.slf4j.Slf4j;
import org.apache.thrift.TProcessor;
import org.apache.thrift.protocol.TBinaryProtocol;
import org.apache.thrift.server.TServer;
import org.apache.thrift.server.TThreadPoolServer;
import org.apache.thrift.transport.TServerSocket;
import org.apache.thrift.transport.TTransportException;
import org.apache.thrift.transport.TTransportFactory;
import org.springframework.beans.BeansException;
import org.springframework.beans.factory.InitializingBean;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.stereotype.Component;

/**
 * 初始化thrift服务
 *
 * @author <a href="jian.huang@bintools.cn">yunzhe</a>
 * @version 1.0.0 2019-07-02-下午7:10
 */
@Component
@Slf4j
public class ThriftServer implements ApplicationContextAware,InitializingBean {
    @Value("${thrift.port}")
    private int port;

    private TBinaryProtocol.Factory protocolFactory;

    private TTransportFactory transportFactory;
    //通过实现ApplicationContextAware,InitializingBean 获取上下文信息
    private static ApplicationContext context;



    public void init(){
        protocolFactory = new TBinaryProtocol.Factory();
        transportFactory = new TTransportFactory();
    }

    public void start(){
        new Thread(){
            @Override
            public void run(){
                TProcessor processor = new HelloService.Processor<HelloService.Iface>(new HelloServiceImpl());
                init();
                try{
                    TServerSocket serverSocket = new TServerSocket(port);
                    TThreadPoolServer.Args args = new TThreadPoolServer.Args(serverSocket);
                    args.protocolFactory(protocolFactory);
                    args.processor(processor);
                    args.transportFactory(transportFactory);
                    TServer server = new TThreadPoolServer(args);
                    log.info("thrift server start success, port={}",port);
                    server.serve();
                }catch (TTransportException e){
                    log.error("thrift server start fail",e);
                }
            }
        }.start();
    }
   // 获取上下文
    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        context=applicationContext;
    }

    @Override
    public void afterPropertiesSet() throws Exception {

    }
}

• 2.2 服务端逻辑处理 （HelloServiceImpl）
  需要对该类实现ApplicationListener<ApplicationContextEvent>实现其中的onApplicationEvent方法。具体代码如下

package cn.bintools.daios.example.thrift.impl;

import cn.bintools.daios.example.thrift.ConnectionInfo;
import cn.bintools.daios.example.thrift.HelloService;
import cn.bintools.daios.example.thrift.server.BusinessServer;
import org.apache.thrift.TException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationListener;
import org.springframework.context.event.ApplicationContextEvent;
import org.springframework.stereotype.Service;

/**
 * 服务端实现
 *
 * @author <a href="jian.huang@bintools.cn">yunzhe</a>
 * @version 1.0.0 2019-07-02-下午7:14
 */
@Service
public class HelloServiceImpl implements HelloService.Iface,ApplicationListener<ApplicationContextEvent> {
    private static ApplicationContext applicationContext;
    @Override
    public int add(int num1, int num2) throws TException {
//通过上下文实例化具体的bean
        BusinessServer server = applicationContext.getBean(BusinessServer.class);
        return server.business();
    }
    @Override
    public ConnectionInfo getConnInfoById(int cpId) throws TException {
        ConnectionInfo connectionInfo = new ConnectionInfo();
        connectionInfo.setConnId(12);
        connectionInfo.setConnectionName("ThrfaceiftConnName");
        connectionInfo.setUrl("192.168.1.162");
        connectionInfo.setPort(3306);
        connectionInfo.setUserName("mysql_conn");
        connectionInfo.setPassword("abc*&ABC123");
        return connectionInfo;
    }
    @Override
    public void onApplicationEvent(ApplicationContextEvent event) {
       //从event中获取上下文信息
        applicationContext = event.getApplicationContext();
    }
}

通过对这两个文件进行相应的处理，就可以实现通过thrift实现具体的业务处理。

三、总结

通过以上测试，可以让thrift进行相应的处理。感觉还有更优的解决方案，希望大家多多指点
