postgresql - 如何从JDBC连接postgres数据库和logstash导入数据？

Question

我正在尝试将 PostgreSQL 数据库与 Logstash 连接，以将数据从 postgres 导入到 elasticsearch。 我正在使用 JDBC 驱动程序将 Logstash 与 postgres 连接起来。

但是我遇到了以下错误

[2019-06-27T13:04:05,943][ERROR][logstash.javapipeline ] A plugin had an unrecoverable error. Will restart this plugin.

我的配置是

• Java 版本 - “1.8.0_211”
• postgres (PostgreSQL) 11.0
• logstash-7.2.0

这是我的 logstash 配置文件

input {
    jdbc{
        #input configuration
        jdbc_driver_library => "postgresql-42.2.6.jar"
        jdbc_driver_class => "org.postgresql.Driver"
        jdbc_connection_string => "jdbc:postgresql://localhost:5432/LogstashTest"
        jdbc_user => "postgres"
        jdbc_password => "root"
        statement => 'SELECT  * FROM public."contacts";'
    }
}
output{
    stdout { codec => json_lines }
}

当您将不正确的配置文件传递给 Logstash 时，问题可能是由于 PostgreSQL JDBC 驱动程序损坏所致。我有同样的问题，你需要检查你的 JDBC 驱动程序文件。
