使用DatabaseMetaData.getMetaData对基础视图all_objects、all_tab_comments和all_synonyms进行回复。这些视图考虑了授予访问权限的内容。
SELECT_CATALOG_ROLE会赠款与目录的存取权，以允许查询dba_objects。
要完成所要求的任务，可以很容易地编写一个Map到DatabaseMetaData.getMetaData（）.getTables（..）的JavaAPI来使用dba_xyz视图。

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.util.Properties;

import oracle.jdbc.OracleConnection;
import oracle.jdbc.OracleDatabaseMetaData;

public class MyMetaData extends OracleDatabaseMetaData {


    public MyMetaData(Connection conn) {
        super((OracleConnection) conn);
    }

    public synchronized ResultSet getTables(String catalog, String schemaPattern, String tableNamePattern, String[] types) throws SQLException {
        // catalog isn't used
        // dba view based sql  

        String sql = "SELECT NULL AS table_cat,"+
        "       o.owner AS table_schem,\n       "+
        "       o.object_name AS table_name,\n  "+
        "       o.object_type AS table_type,\n"+
        "       c.comments AS remarks\n" +
        "  FROM dba_objects o, dba_tab_comments c\n"+
        "  WHERE o.owner LIKE :1 ESCAPE '/'\n    "+
        "  AND o.object_name LIKE :2 ESCAPE '/'\n"+
        "  AND o.owner = c.owner (+)\n    "+
        "  AND o.object_name = c.table_name (+)\n";

        // bind params

         PreparedStatement stmt = connection.prepareStatement(sql);
         stmt.setString(1, schemaPattern == null ? "%" : schemaPattern);
         stmt.setString(2, tableNamePattern == null ? "%" : tableNamePattern);

        return stmt.executeQuery();
    }

    public static void main(String[] args) throws SQLException {

        String conString = "jdbc:oracle:thin:@//localhost:1521/xe";
        Properties props = new Properties();
        props.setProperty("user", "klrice");
        props.setProperty("password", "klrice");
        Connection conn = DriverManager.getConnection(conString, props);
        // use this class
        MyMetaData md = new MyMetaData(conn);

        // test it out
        ResultSet rset = md.getTables(null, "ORDS_METADATA", null, null);
            while (rset.next()) {
                System.out.println(rset.getString(2));
            }    

    }

}

SELECT_CATALOG_ROLE允许对数据字典视图（例如select * from dba_users）具有SELECT权限，但不允许对用户表具有SELECT权限。必须显式指定对所需表的权限，例如grant select,update,delete on need_table for user_name; grant select,update,delete on DEPARTMENTS to test;
或者为所有表给予选择权限（不好做法）。

我在jdbc上也遇到过同样的问题。我的解决方案就是这么简单。

create or replace synonym youruser.all_objects for dba_objects;
create or replace synonym youruser.all_tables for dba_tables;
create or replace synonym youruser.all_tab_columns for dba_tab_columns;
create or replace synonym youruser.all_users for dba_users;
create or replace synonym youruser.all_constraints for dba_constraints;
create or replace synonym youruser.all_cons_columns for dba_cons_columns;

这对我很有效。

感谢@ LotarSchin，您的解决方案如此简单，而且确实有效。在阅读了OracleJDBC驱动程序的源代码后，我有了一个更完整的同义词列表：

create user metadata_collector identified by "password";
grant connect to metadata_collector;
grant select any dictionary to metadata_collector;
create or replace synonym metadata_collector.all_objects for dba_objects;
create or replace synonym metadata_collector.all_tables for dba_tables;
create or replace synonym metadata_collector.all_tab_comments for dba_tab_comments;
create or replace synonym metadata_collector.all_tab_columns for dba_tab_columns;
create or replace synonym metadata_collector.all_col_comments for dba_col_comments;
create or replace synonym metadata_collector.all_users for dba_users;
create or replace synonym metadata_collector.all_constraints for dba_constraints;
create or replace synonym metadata_collector.all_cons_columns for dba_cons_columns;
create or replace synonym metadata_collector.all_arguments for dba_arguments;
create or replace synonym metadata_collector.all_synonyms for dba_synonyms;
create or replace synonym metadata_collector.all_col_privs for dba_col_privs;
create or replace synonym metadata_collector.all_tab_privs for dba_tab_privs;
create or replace synonym metadata_collector.all_ind_columns for dba_ind_columns;
create or replace synonym metadata_collector.all_trigger_cols for dba_trigger_cols;
create or replace synonym metadata_collector.all_indexes for dba_indexes;
create or replace synonym metadata_collector.all_types for dba_types;
