es在win下添加数据（二）
win环境下把MySql中的数据导入到Elasticsearch（二）
环境问题参考我上文：
https://blog.csdn.net/qq_24265945/article/details/81168158
环境问题已经好了，接下来，我们讲实战。
下载：mysql-connector-java-5.1.46.zip
该压缩包帮助mysql与其他平台连接。看到很多资源都要积分，不能选0分，所以选1分了
https://dev.mysql.com/downloads/file/?id=476197
在bin目录下创建jdbc.config
根据需求改连接，账号，密码，名字，端口等等。
input {
stdin {
}
jdbc {
# mysql jdbc connection string to our backup databse
jdbc_connection_string => "jdbc:mysql://127.0.0.1:3306/zhangjiang?characterEncoding=UTF-8&useSSL=false"
# the user we wish to excute our statement as
jdbc_user => "root"
jdbc_password => "111111"
# the path to our downloaded jdbc driver
jdbc_driver_library => "D:/logstash-6.3.1/mysql-connector-java-5.1.46/mysql-connector-java-5.1.46/mysql-connector-java-5.1.46.jar"
# the name of the driver class for mysql
jdbc_driver_class => "com.mysql.jdbc.Driver"
jdbc_paging_enabled => "true"
jdbc_page_size => "50000"
jdbc_default_timezone => "UTC"
statement_filepath => "D:/logstash-6.3.1/logstash-6.3.1/bin/jdbc.sql"
schedule => "* * * * *"
type => "patent"
}
}
filter {
json {
source => "message"
remove_field => ["message"]
}
}
output {
elasticsearch {
hosts => "localhost:9200"
index => "patent"
document_id => "%{id}"
}
stdout {
codec => json_lines
}
}
创建jdbc.sql（这里根据自己需求改啦）
select
Patent_ID as id,
Patent_Num as pnum,
Patent_Name as pname,
Patent_Link as link,
Patent_Applicant as applicant,
Patent_Summary as summary,
Patent_Date as pdate,
Patent_ClassNum as classnum,
Patent_Update as pupdate,
Patent_Status as pstatus
from
patentinfor
在bin中输入 logstash -f jdbc.conf
疯狂导入啦~~~
这里也记录下几个报错的问题给大家参考：
1.
D:\logstash-6.3.1\logstash-6.3.1\bin>logstash -f jdbc.conf

已经有端口使用了。查看下是不是开着别的cmd在调用logstash,关闭就是了

这里是参考了别的网页，本来在下文中还写了port，protocol等内容，删除就是了，同时注意是hosts而不是host；记得查看自己的sql文件，如果sql文件出错，同样会导致导入失败，结果是：可以手动在cmd写内容进es，但是mysql的内容并没有录入es
output {
elasticsearch {
hosts => "localhost:9200"
index => "patent"
document_id => "%{id}"
}
stdout {
codec => json_lines
}
最后附上成功运行后可视化软件kibana图:
一周后的后续：当我加入中文分词工具以后，突然发现一个问题，映射是elasticsearch默认自己创建的 ，一旦创建没有办法修改，所以建议大家插入数据前先创建mapping，把分词工具加进去，具体分词工具我这里采用elasticsearch中的IK Analysis,后续会考虑其他分词工具，比较效果。这里附上我分词工具IK Analysis的安装和使用后续：
