从Oracle数据库获取Java类内容 [英] Get java class content from oracle database

问题描述

是否可以从数据库中获取Java .class文件?
我的意思是java类，它是通过带有-r -s -v -g参数的loadjava工具加载的.

Is it possible to get the java .class file from a database?
I mean java classes, which was loaded via loadjava tool with -r -s -v -g parameters.

该怎么做?

修改: 我需要它以可读的形式；)

I need it in readable form ;)

推荐答案

看看

Take a look at the DBMS_JAVA package.
With DBMS_JAVA you can export both .java and .class files, using:

• export_source-导出.java文件

PROCEDURE export_source(name VARCHAR2, schema VARCHAR2, blob BLOB)
PROCEDURE export_source(name VARCHAR2, blob BLOB)
PROCEDURE export_source(name VARCHAR2, clob CLOB)

export_class-导出.class文件

export_class - to export .class file

PROCEDURE export_class(name VARCHAR2, schema VARCHAR2, blob BLOB)
PROCEDURE export_class(name VARCHAR2, blob BLOB)

此处，您可以找到一些有关如何使用该示例的示例阅读.java文件的来源.

Here you can find some examples on how to use that to read the source of .java files.
