Mecab-ko 韩文分词器安装与使用

环境信息:

Linux: centos7 (debian编译碰到了好多依赖问题，需要一个个调试)

Docker也是同样的问题，推荐使用centos7镜像

1. 前置依赖安装

# 编译依赖安装
yum install -y gcc gcc-c++ wget automake autoconf autogen

2. mecab-ko 编译安装

mecab-ko：基础库

mecab-ko-dic：字典库

mecab-java：外部执行程序，必须在linux下。其实主要是为了生成 libMeCab.so 和 MeCab.jar

编译后的文件都放到了： /usr/local/lib 和 /usr/local/bin下

# 1. mecab-ko 安装
wget https://bitbucket.org/eunjeon/mecab-ko/downloads/mecab-0.996-ko-0.9.2.tar.gz
# 解压
tar xvfz mecab-0.996-ko-0.9.2.tar.gz
cd mecab-0.996-ko-0.9.2
# 编译安装
./configure
make & make install
# 验证是否安装成功
mecab --version

# 2. mecab-ko-dic 安装
wget https://bitbucket.org/eunjeon/mecab-ko-dic/downloads/mecab-ko-dic-2.1.1-20180720.tar.gz
# 解压
tar xvfz mecab-ko-dic-2.1.1-20180720.tar.gz
cd mecab-ko-dic-2.1.1-20180720
# 编译安装 
sudo ./autogen.sh
./configure
make & make install
ldconfig

# 3.安装jdk,这里以jdk-11.0.12为例,jdk解压到/opt/jdk-11.0.2路径下
wget https://cdn.azul.com/zulu/bin/zulu11.58.23-ca-jdk11.0.16.1-linux_x64.tar.gz

# 4.mecab-java安装
wget https://bitbucket.org/eunjeon/mecab-java/downloads/mecab-java-0.996.tar.gz
# 解压
tar zxvf mecab-java-0.996.tar.gz
# 编辑Makefile文件，更新jdk地址
vi Makefile
# ----------------------
# java环境变量替换
INCLUDE=/opt/jdk-11.0.2/include
JAVAC=/opt/jdk-11.0.2/bin/javac
JAR=/opt/jdk-11.0.2/bin/jar
# -----------------------

# 复制编译好之后的文件到/usr/local/lib 下
sudo cp libMeCab.so /usr/local/lib 
sudo cp MeCab.jar /usr/local/lib


# 配置环境变量
echo "export LD_LIBRARY_PATH=/usr/local/lib" >> ~/.bash_profile 
# 或
vim ~/.bash_profile
#------------------
export LD_LIBRARY_PATH=/usr/local/lib
#-----------------
source ~/.bash_profile
# 执行完以上操作后就可以进入mecab-java环境进行测试
cd /mecab-java
# javac 编译
/opt/jdk-11.0.2/bin/javac test.java
# java执行
/opt/jdk-11.0.2/bin/java test

#/opt/jdk-11.0.2/bin/javac -cp MeCab.jar test.java
#/opt/jdk-11.0.2/bin/java -Djava.library.path=/usr/local/bin/mecab-java -cp .:MeCab.jar test

3. Dockerfile

先准备好如下文件，放到docker打包路径下：


[root@localhost docker]# ll
总用量 4
drwxr-xr-x. 9 root root  141 10月 14 15:05 build
-rw-r--r--. 1 root root 1891 10月 14 12:53 Dockerfile
drwxr-xr-x. 2 root root  183 10月 14 10:42 public
[root@localhost docker]#

# build 为java编译后生成的路径
# public 为资源文件

# public资源文件如下：
总用量 244684

4. 常用Docker命令

systemctl restart docker

# docker 测试
# 打包资源上传路径
cd /opt/docker

# 生成image镜像
docker build -t mecab-ko:v2.4 .

# container 运行image镜像
docker run -d --name mecab-ko -p 8000:8000 mecab-ko:v2.4

# 进入容器
docker exec -it d4d09122009d /bin/bash

# 停止所有docker container
docker stop $(docker ps -a -q)

# 删除所有docker container
docker rm $(docker ps -a -q)

5. SpringBoot核心代码

需要将mecab-java-0.996项目下的 org.chasen.mecab 包及类文件完整的拷贝到你的Springboot项目中。

/**
 * @author: curyu
 * @date: 2022/10/13 10:51
 * @description:
 */
@RestController
@RequestMapping("mecab")
public class MecabController {

    static {
        try {
            System.loadLibrary("MeCab");
        } catch (UnsatisfiedLinkError e) {
            System.err.println("Cannot load the example native code.nMake sure your LD_LIBRARY_PATH contains '.'n" + e);
            System.exit(1);
        }
    }

    @SneakyThrows
    @GetMapping("/api")
    public List<Map<String, Object>> mecabKeywords(String text) {
        List<Map<String, Object>> resultList = new ArrayList<>();
        String[] split = text.split("\r\n");
        for (String s : split) {
            Map<String, Object> map = doMecab(s);
            resultList.add(map);
        }
        return resultList;
    }

    private Map<String, Object> doMecab(String text) {
        Map<String, Object> result = new HashMap<>();
        List<String> list = new ArrayList<>();
        System.out.println(MeCab.VERSION);
        Tagger tagger = new Tagger();
        String record1 = tagger.parse(text);
        Node node = tagger.parseToNode(text);
        result.put("sourceText", text);
        // result.put("targetParse", record1);
        for (; node != null; node = node.getNext()) {
            String record3 = node.getSurface();
            list.add(record3);
            if (node.getSurface() != null && !("").equals(node.getSurface()) && node.getSurface().toString().length() > 0) {
                result.put("targetNode", list);
            }
        }
        return result;
    }

}
