最近来了个thrift+swift的分布式架构项目、所以就研究了一下这套远程调度框架的使用、中间踩了很多坑
首先介绍一下用到的几个插件和jar包
<plugin>
<groupId>com.facebook.mojo</groupId>
<artifactId>swift-maven-plugin</artifactId>
<version>${swift-version}</version>
<executions>
<execution>
<goals>
<goal>generate</goal>
</goals>
</execution>
</executions>
<configuration>
<skip>false</skip>
<idlFiles>
<directory>${project.basedir}/src/main/thrift/</directory>
<includes>
<include>**/*.thrift</include>
</includes>
<!--<excludes>-->
<!--<exclude>**/other.thrift</exclude>-->
<!--</excludes>-->
</idlFiles>
<defaultPackage>${project.groupId}.thrift.hello</defaultPackage>
<outputFolder>${project.basedir}/src/main/java/</outputFolder>
</configuration>
</plugin>
该插件是生成服务端接口的插件、搭建的测试环境上用的版本是0.23.1
<dependency>
<groupId>com.facebook.swift</groupId>
<artifactId>swift-service</artifactId>
<version>${swift-version}</version>
</dependency>
<dependency>
<groupId>com.facebook.swift</groupId>
<artifactId>swift-annotations</artifactId>
<version>${swift-version}</version>
</dependency>
这两个jar包是通过注解来简化生成的服务端API代码的、这两个jar包和swift-maven-plugin插件版本保持一致。
<!--0.9.1-0.13.0-->
<dependency>
<groupId>org.apache.thrift</groupId>
<artifactId>libthrift</artifactId>
<version>0.13.0</version>
</dependency>
最坑的是这个jar包版本的选择上、自测版本从0.9.1到0.13.0都可以、再往后的版本就不行了
一直报如下异常

请大家以此为戒
框架搭建以及使用方法可参考杨过大侠的这篇文章 https://www.cnblogs.com/yjmyzz/p/thrift-swift-sample.html
