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：

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。
