The username is usually not null, but it could be for some embedded databases.
Always setting generatedKeysColumnNameArraySupported to false when getGeneratedKeysSupported is false, since it can't be supported without having generated keys supported. This change only affects logging messages.
Issue: SPR-9006
Adding a static CustomSQLExceptionTranslatorRegistry and a CustomSQLExceptionTranslatorRegistrar that can be used to register custom SQLExceptionTranslator implementations for specific databases from any application context.
This can be used in application contexts like this:
<bean class="org.springframework.jdbc.support.CustomSQLExceptionTranslatorRegistrar">
<property name="sqlExceptionTranslators">
<map>
<entry key="H2">
<bean class="com.yourcompany.data.CustomSqlExceptionTranslator"/>
</entry>
</map>
</property>
</bean>

Prior to this change, single quotes were incorrectly parsed by
NamedParameterUtils#parseSqlStatement, resulting in incorrect parameter
counts:
ParsedSql sql = NamedParameterUtils
.parseSqlStatement("SELECT 'foo''bar', :xxx FROM DUAL");
assert sql.getTotalParameterCount() == 0 // incorrect, misses :xxx
That is, presence of the single-quoted string caused the parser to
overlook the named parameter :xxx.
This commit fixes the parsing error such that:
ParsedSql sql = NamedParameterUtils
.parseSqlStatement("SELECT 'foo''bar', :xxx FROM DUAL");
assert sql.getTotalParameterCount() == 1 // correct
Issue: SPR-8280
ResourceDatabasePopulator is a component that underlies the database
initialization support within Spring's jdbc: namespace, e.g.:
<jdbc:initialize-database data-source="dataSource">
<jdbc:script execution="INIT" location="classpath:init.sql"/>
</jdbc:initialize-database>
Prior to this commit, ResourceDatabasePopulator#executeSqlScript's use
of Statement#executeUpdate(sql) precluded the possibility of SELECT
statements because returning a result is not permitted by this method
and results in an exception being thrown.
Whether this behavior is a function of the JDBC specification or an
idiosyncracy of certain implementations does not matter as the issue
can be worked around entirely. This commit eliminates use
of #executeUpdate(sql) in favor of #execute(sql) followed by a call
to #getUpdateCount, effectively allowing any kind of SQL statement to
be executed during database initialization.
Issue: SPR-8932
Prior to this change, roughly 5% (~300 out of 6000+) of files under the
source tree had CRLF line endings as opposed to the majority which have
LF endings.
This change normalizes these files to LF for consistency going forward.
Command used:
$ git ls-files | xargs file | grep CRLF | cut -d":" -f1 | xargs dos2unix
Issue: SPR-5608
Decomposed Environment interface into PropertySources, PropertyResolver
objects
Environment interface and implementations are still present, but
simpler.
PropertySources container aggregates PropertySource objects;
PropertyResolver provides search, conversion, placeholder
replacement. Single implementation for now is
PropertySourcesPlaceholderResolver
Renamed EnvironmentAwarePropertyPlaceholderConfigurer to
PropertySourcesPlaceholderConfigurer
<context:property-placeholder/> now registers PSPC by default, else
PPC if systemPropertiesMode* settings are involved
Refined configuration and behavior of default profiles
See Environment interface Javadoc for details
Added Portlet implementations of relevant interfaces:
* DefaultPortletEnvironment
* PortletConfigPropertySource, PortletContextPropertySource
* Integrated each appropriately throughout Portlet app contexts
Added protected 'createEnvironment()' method to AbstractApplicationContext
Subclasses can override at will to supply a custom Environment
implementation. In practice throughout the framework, this is how
Web- and Portlet-related ApplicationContexts override use of the
DefaultEnvironment and swap in DefaultWebEnvironment or
DefaultPortletEnvironment as appropriate.
Introduced "stub-and-replace" behavior for Servlet- and Portlet-based
PropertySource implementations
Allows for early registration and ordering of the stub, then
replacement with actual backing object at refresh() time.
Added AbstractApplicationContext.initPropertySources() method to
support stub-and-replace behavior. Called from within existing
prepareRefresh() method so as to avoid impact with
ApplicationContext implementations that copy and modify AAC's
refresh() method (e.g.: Spring DM).
Added methods to WebApplicationContextUtils and
PortletApplicationContextUtils to support stub-and-replace behavior
Added comprehensive Javadoc for all new or modified types and members
Added XSD documentation for all new or modified elements and attributes
Including nested <beans>, <beans profile="..."/>, and changes for
certain attributes type from xsd:IDREF to xsd:string
Improved fix for detecting non-file based Resources in
PropertiesLoaderSupport (SPR-7547, SPR-7552)
Technically unrelated to environment work, but grouped in with
this changeset for convenience.
Deprecated (removed) context:property-placeholder
'system-properties-mode' attribute from spring-context-3.1.xsd
Functionality is preserved for those using schemas up to and including
spring-context-3.0. For 3.1, system-properties-mode is no longer
supported as it conflicts with the idea of managing a set of property
sources within the context's Environment object. See Javadoc in
PropertyPlaceholderConfigurer, AbstractPropertyPlaceholderConfigurer
and PropertySourcesPlaceholderConfigurer for details.
Introduced CollectionUtils.toArray(Enumeration<E>, A[])
Work items remaining for 3.1 M2:
Consider repackaging PropertySource* types; eliminate internal use
of SystemPropertyUtils and deprecate
Further work on composition of Environment interface; consider
repurposing existing PlaceholderResolver interface to obviate need
for resolve[Required]Placeholder() methods currently in Environment.
Ensure configurability of placeholder prefix, suffix, and value
separator when working against an AbstractPropertyResolver
Add JNDI-based Environment / PropertySource implementatinos
Consider support for @Profile at the @Bean level
Provide consistent logging for the entire property resolution
lifecycle; consider issuing all such messages against a dedicated
logger with a single category.
Add reference documentation to cover the featureset.
Branch in question is 'env' branch from git://git.springsource.org/sandbox/cbeams.git; merged into
git-svn repository with:
git merge -s recursive -Xtheirs --no-commit env
No merge conflicts, but did need to
git rm spring-build
prior to committing.
With this change, Spring 3.1.0 development is now happening on SVN
trunk. Further commits to the 3.0.x line will happen in an as-yet
uncreated SVN branch. 3.1.0 snapshots will be available
per the usual nightly CI build from trunk.
