  <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>.
