Type: CLI entry point (standalone, NOT Spring Boot) · Lines: 130 · Author: Roger Rene Kommer

Purpose: Command-line entry point for the SchemaExp tool — manually boots a minimal Spring context, parses CLI arguments, and delegates to SchemaExpService for export/import/clear operations.

How it differs from the main app

Unlike the main ProjectForge application which uses Spring Boot (SpringApplication.run(ProjectForgeApplication.class, args)), this tool manually bootstraps a plain Spring context:

ApplicationContext context = new AnnotationConfigApplicationContext(SchemaExpContext.class);
TenantRegistryMap.getInstance().setApplicationContext(context);
DatabaseSupport.setInstance(new DatabaseSupport(HibernateUtils.getDialect()));

Three manual bootstrapping steps replace what Spring Boot does automatically: context creation, tenant registry registration, and Hibernate dialect setup. This gives the tool a minimal footprint — no embedded Tomcat, no Spring Security, no Quartz scheduler.

CLI argument parsing

The tool accepts options followed by a single file argument. Supported flags:

Flag	Effect
`-exp`	Export operation → `SchemaExpService.doExport()`
`-imp`	Import operation → `SchemaExpService.doImport()`
`-cleardb`	Drop all tables before import (or standalone clear)
`-insertnew`	RestoreMode.InsertNew — skip existing records
`-overwrite`	RestoreMode.OverWrite — update existing records
`-insertall`	RestoreMode.InsertAll — insert everything (default)

The option parser (parseOption(), lines 40-65) uses StringUtils.equalsIgnoreCase() for case-insensitive matching. Positional options — flags must come before the file argument. The while (parseOption(args, pos++)) loop (line 78) iterates until it hits a non-option, then --pos backs up to point at the first non-option argument (the filename).

Known issues

Typo: initApplicatinContext (line 122) — missing 'o' in "Application". The typo exists in both the method name and its call site (line 73).
Dead code: The catch (IllegalArgumentException) block on line 82 never executes — parseOption() never throws this exception.
Dead check: Lines 95-98 check restoreMode == null but restoreMode is initialized to RestoreMode.InsertAll (line 36) and never set to null. This check can never trigger.
No exit codes: The program always exits with code 0, even on exceptions. Scripting in CI requires stdout/stderr parsing.
Broad component scan: @ComponentScan({"org.projectforge", ...}) (in SchemaExpContext) brings in thousands of beans — much more than needed. Context startup can be slow.
