java - com.mysql.jdbc.Driver 未加载。您确定在 :jdbc_driver_library 中包含了正确的 jdbc 驱动程序吗

Question

我遇到了 java 版本和 mysql-connect-java.jar 与 logstash 的兼容性问题。

谁能告诉我哪个版本的 mysql-connect-java.jar 与哪个版本的 java 兼容？

错误:

com.mysql.cj.jdbc.Driver not loaded. Are you sure you've included the correct jdbc driver in :jdbc_driver_library?

我当前的java版本是

openjdk version "1.8.0_212"
OpenJDK Runtime Environment (build 1.8.0_212-8u212-b03-0ubuntu1.16.04.1-b03)
OpenJDK 64-Bit Server VM (build 25.212-b03, mixed mode)

我已尝试使用以下 mysql 连接器 jar 文件，但每一个都失败了。

mysql-connector-java-8.0.16.jar
mysql-connector-java-8.0.15.jar
mysql-connector-java-6.0.5.jar
mysql-connector-java-5.1.46.jar
mysql-connector-java-5.1.4.jar

Logstash 配置文件是 mysql.conf

input {
    jdbc {
        jdbc_connection_string => "jdbc:mysql://localhost:3306/prbi"
        jdbc_user => "root"
        jdbc_password => ""
        jdbc_driver_library => "mysql-connector-java-8.0.15.jar" #tried above every jar
        jdbc_driver_class => "com.mysql.cj.jdbc.Driver" #tried com.mysql.jdbc.Driver too
        schedule => "* * * * *"
        use_column_value => true
        tracking_column => "%{id}"
        clean_run => true
        statement => "SELECT * from tmp_j_summaryrepor"
    }
}
output {
    elasticsearch {
    hosts => ['http://localhost:9200']
    index => "prsummaryreport"
    document_type => "prsummaryreport"
    document_id => "%{id}" # It is a Primary Key of table
    }
    stdout { codec => json_lines } 
}

对于 logstash 6.2.x 及更高版本，更喜欢在以下位置添加驱动程序:

/usr/share/logstash/logstash-core/lib/jars/

而是让 jdbc_driver_library 为空。许多 elastic.co 论坛也引用了这一点。
