Formのパス分割
大規模なアプリケーションでは、パスを分割することもできます。例えば、/aaa/bbb/のパスに対応するアクションクラスは、ルートパッケージ.action.aaa.BbbActionになります。
http://sastruts.seasar.org/featureReference.html#Action
にあるように、Actionはパスを分割できます。Actionと同じ階層にFormもあったほうがいいのでFormもパス分割してみました。
まずはAction。
package sample.action.foo; import javax.annotation.Resource; import org.seasar.struts.annotation.ActionForm; import org.seasar.struts.annotation.Execute; import sample.form.foo.TestForm; public class TestAction { @ActionForm @Resource protected TestForm testForm; @Execute(validator = false) public String index() { testForm.hoge="aaa"; return "test.jsp"; } }
Formは、以下。
package sample.form.foo; public class TestForm { public String hoge; }
これで動かすと、問題なく動きます。
この状態から、Formの変数名をformにしたいので、ActionクラスのForm指定部分の@Resourceのnameを指定します。
package sample.action.foo; import javax.annotation.Resource; import org.seasar.struts.annotation.ActionForm; import org.seasar.struts.annotation.Execute; import sample.form.foo.TestForm; public class TestAction { @ActionForm @Resource(name = "testForm") protected TestForm form; @Execute(validator = false) public String index() { form.hoge = "aaa"; return "test.jsp"; } }
そうすると、以下のエラーになります。

上記は、HotDeployですが、CoolDeployでも同じです。
じゃあ、それならと、パスを分割せずにルートパッケージ以下の、actionとformパッケージに上記のソースを移動（以下）すると動きます。
package sample.action; import javax.annotation.Resource; import org.seasar.struts.annotation.ActionForm; import org.seasar.struts.annotation.Execute; import sample.form.TestForm; public class TestAction { @ActionForm @Resource(name = "testForm") protected TestForm form; @Execute(validator = false) public String index() { form.hoge = "aaa"; return "test.jsp"; } }
これは仕様？
