总结一下2017年的时候使用的技术  
**1 java中的使用**  
**1.1 生成thrift文件**  
[thrift-generator][]下载一下源码，自己编译一下。  
`pom.xml`

<dependency>
                <groupId>org.apache.thrift</groupId>
                <artifactId>libthrift</artifactId>
                <version>0.13.0</version>
            </dependency>
    
            <dependency>
                <groupId>com.sohu.thrift</groupId>
                <artifactId>thrift-generator</artifactId>
                <version>0.1.0-SNAPSHOT</version>
                <scope>test</scope>
            </dependency>
    
            <dependency>
                <groupId>junit</groupId>
                <artifactId>junit</artifactId>
                <scope>test</scope>
                <version>4.13.1</version>
            </dependency>

按照下面的代码，生成thrift文件，将输出的内容，保存到一个`.thrift`文件。

import com.sohu.thrift.generator.builder.ThriftFileBuilder;
    import org.junit.Test;
    
    public class ThriftGen { 
    
        private ThriftFileBuilder fileBuilder = new ThriftFileBuilder();
    
        @Test
        public void toOutputstream() throws Exception { 
            this.fileBuilder.buildToOutputStream(PersonService.class, System.out);
        }
    }
    
    import java.util.List;
    
    public class Person { 
    
        public String getCode() { 
            return code;
        }
    
        public void setCode(String code) { 
            this.code = code;
        }
    
        public String getName() { 
            return name;
        }
    
        public void setName(String name) { 
            this.name = name;
        }
    
        public SexEnum getSex() { 
            return sex;
        }
    
        public void setSex(SexEnum sex) { 
            this.sex = sex;
        }
    
        private String code;
    
        private String name;
    
        private SexEnum sex;
    
        private List<Favorite> favoriteList;
    }
    
    
    public class Favorite { 
    
        private String id;
    
        public String getId() { 
            return id;
        }
    
        public void setId(String id) { 
            this.id = id;
        }
    
        public String getName() { 
            return name;
        }
    
        public void setName(String name) { 
            this.name = name;
        }
    
        private String name;
    }
    
    
    
    public enum  SexEnum { 
        MAN,
        WOMAN,
        ALL;
    }
    // 生成相应的thrift文件
    namespace java com.dzmsoft.thriftdemo.api.service.thrift
    
    enum SexEnum { 
            MAN = 0,
            WOMAN = 1,
            ALL = 2
    }
    
    struct Favorite { 
            1:string id,
            2:string name
    }
    struct Person { 
            1:string code,
            2:string name,
            3:SexEnum sex,
            4:list<Favorite> favoriteList
    }
    
    
    service PersonService { 
            bool save(1:Person arg0),
            list<Favorite> getPersons(1:string arg0)
    }

数据类型还是要简单点好，复杂了，还是会有问题，比如下方定义的枚举类型，生成的结构就会很奇怪，这个肯定直接用不了。

package com.dzmsoft.thriftdemo.test.pojo;
    
    public enum  SexEnum { 
        MAN("男","00"),
        WOMAN("女","01"),
        ALL("全部","02");
    
        private final String display;
        private final String value;
    
        private SexEnum(String display , String value){ 
            this.value = value;
            this.display = display;
        }
    
        public String display(){ 
            return this.display;
        }
    
        public String value(){ 
            return this.value;
        }
    
        public static SexEnum getSexEnum(String value){ 
            SexEnum current = null;
            for (SexEnum sexEnum:SexEnum.values()){ 
                if (sexEnum.value().equals(value)){ 
                    current = sexEnum;
                    break;
                }
            }
            return current;
        }
    }
    enum SexEnum { 
    			MAN = 0,
    			WOMAN = 1,
    			ALL = 2,
    			display = 3,
    			value = 4
    	}

**1.2 根据thrift生成python的代码**  
根据thrift文件生成python相关的代码？  
在[apache thrift][]中下载thrift压缩包，然后到[thrift install][]教程，我这里用的mac电脑  
[boost library ][boost library]  
[libevent][]

cd /Users/dzm/Downloads/boost_1_75_0
    ./bootstrap.sh
    sudo ./b2 threading=multi address-model=64 variant=release stage install
    
    # 这里其实应该下载稳定的版本，直接下载对应的master中的，所以可能是alpha版本，安装需要一定时间,在mac采用下面的方式
    192:libevent-2.1.12-stable dzm$ openssl version
    OpenSSL 0.9.8zh 14 Jan 2016
    
    # /usr/local/Cellar/openssl
    brew update
    brew install openssl
    # 上面的操作，还不如执行下面的
    brew reinstall openssl
    
    
    
    # libevent依赖openssh，所以安装这个之前，先把openssl安装了
    cd /Users/dzm/Downloads/libevent-2.1.12-stable
    
    make && make install
    
    cd /Applications/apps/thrift-0.13.0

安装libevent的时候提示的错误，这里

configure: error: openssl is a must but can not be found. You should add the directory containing `openssl.pc' to the `PKG_CONFIG_PATH' environment variable, or set `CFLAGS' and `LDFLAGS' directly for openssl, or use `--disable-openssl' to disable support for openssl encryption

更改brew的仓库路径,这里参考了[mac使用brew update无反应,更新慢解决办法][mac_brew update]

# 替换brew
    cd "$(brew --repo)"
    git remote set-url origin https://mirrors.aliyun.com/homebrew/brew.git
    
    # 替换homebrew-core
    cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
    git remote set-url origin https://mirrors.aliyun.com/homebrew/homebrew-core.git
    
    # 替换homebrew-bottles 访问地址
    192:homebrew-core dzm$ echo $SHELL
    /bin/bash
    
    echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.aliyun.com/homebrew/homebrew-bottles' >> ~/.bash_profile
    source ~/.bash_profile
    
    # 如果要撤销上面的操作
    cd "$(brew --repo)"
    git remote set-url origin https://github.com/Homebrew/brew.git
    cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
    git remote set-url origin https://github.com/Homebrew/homebrew-core.git
    vi ~/.bash_profile
    # 然后，删除 HOMEBREW_BOTTLE_DOMAIN 这一行配置
    source ~/.bash_profile
