dbeaver 创建资源管理

 

 

类似这样，创建一个自定义的资源文件管理，需要按以下步骤创建:

1. 在plugin.xml中创建文档类型

 

 其中base-type属性可不填，示例代码如下：  https://alvinalexander.com/java/jwarehouse/eclipse/org.eclipse.core.tests.runtime/plugin.xml.shtml

<?xml version="1.0" encoding="UTF-8"?>
<?eclipse version="3.0"?>

2. 定义资源处理类 org.jkiss.dbeaver.ui.controls.querylog.SQLiteHandlerImpl  这个类自己创建

 

 其中id属性不可缺省，否则程序运行会NPE

 

 

 需要注意的是: 操作文件时进入不同的handler 是会根据文件的后缀名判断。
