<title>Migrating to Spring Framework 3.2</title>

<para>In this appendix we discuss what users will want to know when upgrading to

Spring Framework 3.2. For a general overview of features, please see

<xref linkend="new-in-3.2"/></para>

<section xml:id="migration-3.2-new-optional-deps">

<title>Newly optional dependencies</title>

<para>Certain inter-module dependencies are now <literal>optional</literal> at the

Maven POM level where they were once required. For example, <literal>spring-tx</literal>

and its dependence on <literal>spring-context</literal>. This may result in <literal>

ClassNotFoundErrors</literal> or other similar problems for users that have been relying

on transitive dependency management to pull in affected downstream <literal>spring-*

</literal>. To resolve this problem, simply add the appropriate missing jars to your

build configuration.</para>

</section>

<section xml:id="migration-3.2-ehcache-support">

<title>EHCache support moved to spring-context-support</title>

<para>Along with Spring's new JCache support, the EHCache support classes in the

<literal>org.springframework.cache.ehcache</literal> package moved from the

<literal>spring-context</literal> module to <literal>spring-context-support</literal>.</para>

</section>

<section xml:id="migration-3.2-inline-asm">

<title>Inlining of spring-asm jar</title>

<para>In versions 3.0 and 3.1, we published a discrete <literal>spring-asm</literal>

containing repackaged <literal>org.objectweb.asm</literal> 3.x sources. As of Spring

Framework 3.2, we have upgraded to <literal>org.objectweb.asm</literal> 4.0 and done

away with the separate module jar, favoring inlining these classes directly within

<literal>spring-core</literal>. This should cause no migration issue for most users;

but on the off chance that you have <literal>spring-asm</literal> declared directly

within your project's build script, you'll want to remove it when upgrading to

Spring Framework 3.2.</para>

</section>

<section xml:id="migration-3.2-inline-cglib">

<title>Explicit CGLIB dependency no longer required</title>

<para>In prior versions, users of Spring's subclass-based AOP proxies (e.g. via

<literal>proxy-target-class="true"</literal>) and <literal>@Configuration</literal>

class support were required to declare an explicit dependency on CGLIB 2.2. As of

Spring Framework 3.2, we now repackage and inline the newly-released CGLIB 3.0.</para>

<para>This means greater convenience for users, as well as correct functionality for

Java 7 users who are creating subclass proxies of types that contain <literal>

invokedynamic</literal> bytecode instructions. Repackaging CGLIB internally ensures

no classpath conflicts with other third party frameworks that may depend on other

versions of CGLIB.</para>

</section>

<section xml:id="migration-3.2-osgi-users">

<title>For OSGi users</title>

<para>OSGi metadata is no longer published within individual Spring Framework

jar MANIFEST.MF files. Please see this

<link xl:href="http://www.springsource.org/springframework-ebr">announcement</link>

for more information about how users can get OSGi-ready versions of Spring

Framework 3.2 jars.</para>

</section>

<section xml:id="migration-3.2-compatibility-mvc-config">

<title>MVC Java Config and MVC Namespace</title>

<para>As explained in <xref linkend="mvc-config-content-negotiation"/>, both

the MVC Java config and the MVC namespace register extensions such as

<filename>.json</filename> and <filename>.xml</filename> if the

corresponding classpath dependencies are present. That means controller

methods may now return JSON or XML formatted content if those

extensions are present in the request URI,

even if the 'Accept' header doesn't request those media types.</para>

<para>The newly added support for matrix variables is explained in

<xref linkend="mvc-ann-matrix-variables"/>. To preserve backward

compatibility, by default, semicolon content is removed from incoming

request URIs and therefore <interfacename>@MatrixVariable</interfacename>

cannot be used without additional configuration. However, when using

the MVC Java config and the MVC namespace, semicolon content is left

in the URI so that matrix variables are automatically supported.

The removal of semicolon content is controlled through the

<classname>UrlPathHelper</classname> property of

<classname>RequestMappingHandlerMapping</classname>.</para>

</section>

<section xml:id="migration-3.2-compatibility-uri-variable-values">

<title>Decoding of URI Variable Values</title>

<para>URI variable values now get decoded when

<code>UrlPathHelper.setUrlDecode</code> is set to <code>false</code>.

See <link xl:href="https://jira.springsource.org/browse/SPR-9098">SPR-9098</link>.</para>

</section>

<section xml:id="migration-3.2-compatibility-http-patch">

<title>HTTP PATCH method</title>

<para>The <classname>DispatcherServlet</classname> now allows the

HTTP PATCH method where previously it didn't.</para>

</section>

<section xml:id="migration-3.2-compatibility-tiles3">

<title>Tiles 3</title>

<para>Besides the version number change, the set of Tiles

dependencies has also changed. You will need to have a subset or all of

<filename>tiles-request-api</filename>, <filename>tiles-api</filename>,

<filename>tiles-core</filename>, <filename>tiles-servlet</filename>,

<filename>tiles-jsp</filename>, <filename>tiles-el</filename>.

</para>

</section>

<section xml:id="migration-3.2-compatibility-spring-mvc-test">

<title>Spring MVC Test standalone project</title>

<para>If migrating from the

<link xl:href="https://github.com/SpringSource/spring-test-mvc">spring-test-mvc</link>

standalone project to the <filename>spring-test</filename> module in

Spring Framework 3.2, you will need to adjust the root package

to be <classname>org.springframework.test.web.servlet</classname>.</para>

<para>You will no longer be able to use the

<classname>MockMvcBuilders</classname> <code>annotationConfigSetup</code>

and <code>xmlConfigSetup</code> options. Instead you'll need to switch

to using the <interfacename>@WebAppConfiguration</interfacename> support

of <filename>spring-test</filename> for loading Spring configuration,

then inject a <interfacename>WebApplicationContext</interfacename> into

the test and use it to create a <classname>MockMvc</classname>. See

<xref linkend="spring-mvc-test-framework" /> for details.</para>

</section>

<section xml:id="migration-3.2-compatibility-spring-test">

<title>Spring Test Dependencies</title>

<para>The <literal>spring-test</literal> module has been upgraded to

depend on JUnit 4.11 (<literal>junit:junit</literal>), TestNG 6.5.2

(<literal>org.testng:testng</literal>), and Hamcrest Core 1.3

(<literal>org.hamcrest:hamcrest-core</literal>). Each of these

dependencies is declared as an <emphasis>optional</emphasis> dependency in

the Maven POM. Furthermore, it is important to note that the JUnit team

has stopped inlining Hamcrest Core within the

<literal>junit:junit</literal> Maven artifact as of JUnit 4.11. Hamcrest

Core is now a <emphasis>required</emphasis> transitive dependency of

<literal>junit</literal>, and users may therefore need to remove any

exclusions on <literal>hamcrest-core</literal> that they had previously

configured for their build.</para>

</section>

<section xml:id="migration-3.2-changes">

<title>Public API changes</title>

<section xml:id="migration-3.2-api-changes">

<title>JDiff reports</title>

<para>

Select JDiff reports are now being published to provide users with a convenient

means of understanding what's changed between versions. Going forward these will be

published between each minor version, e.g. from 3.1.3.RELEASE to 3.1.4.RELEASE; from

the latest maintenance version to the latest GA release, e.g.

<link xl:href="http://static.springsource.org/spring-framework/docs/3.1.3.RELEASE_to_3.2.0.RELEASE">

3.1.3.RELEASE to 3.2.0.RELEASE</link>; and in between each milestone

and/or RC for users who are tracking next-generation development, e.g.

<link xl:href="http://static.springsource.org/spring-framework/docs/3.2.0.RC2_to_3.2.0.RELEASE">

3.2.0.RC2 to 3.2.0.RELEASE</link>.
