Spring任务调度器之Task的使用
在struts2的返回结果配置中,我们大部分情况使用默认的或者chain或者redirect,其实struts2还有很多其他类型的,今天我们就来看一下都有哪些类型。
打开struts2的源码中struts-default.xml文件,我们能看到如下配置
< xmlnamespace prefix ="v" ns ="urn:schemas-microsoft-com:vml" />< xmlnamespace prefix ="o" ns ="urn:schemas-microsoft-com:office:office" />
<package name="struts-default" abstract="true">
<result-types>
<result-type name="chain"class="com.opensymphony.xwork2.ActionChainResult"/>
<result-type name="dispatcher"class="org.apache.struts2.dispatcher.ServletDispatcherResult" default="true"/>
<result-type name="freemarker"class="org.apache.struts2.views.freemarker.FreemarkerResult"/>
<result-type name="httpheader"class="org.apache.struts2.dispatcher.HttpHeaderResult"/>
<result-type name="redirect"class="org.apache.struts2.dispatcher.ServletRedirectResult"/>
<result-type name="redirectAction"class="org.apache.struts2.dispatcher.ServletActionRedirectResult"/>
<result-type name="stream"class="org.apache.struts2.dispatcher.StreamResult"/>
<result-type name="velocity"class="org.apache.struts2.dispatcher.VelocityResult"/>
<result-type name="xslt"class="org.apache.struts2.views.xslt.XSLTResult"/>
<result-type name="plainText"class="org.apache.struts2.dispatcher.PlainTextResult" />
<!-- Deprecated name form scheduled for removal in Struts 2.1.0. The camelCase versions are preferred. See ww-1707 -->
<result-type name="redirect-action"class="org.apache.struts2.dispatcher.ServletActionRedirectResult"/>
<result-type name="plaintext"class="org.apache.struts2.dispatcher.PlainTextResult" />
</result-types>
注1:redirect与redirect-action区别 |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
一、使用redirect需要后缀名 使用redirect-action不需要后缀名 |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
二、type="redirect" 的值可以转到其它命名空间下的action,而redirect-action只能转到同一命名空下的 action,因此它可以省略.action的后缀直接写action的名称。 |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
如: |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
<result name="success" type="redirect">yhj.do</result> <result name="success" type="redirect-action">yhj</result> |

or database or service layer), but can't load that object
until at least the ID parameter has been loaded. By loading
the parameters twice, you can retrieve the object in the
prepare() method, allowing the second params interceptor to
apply the values on the object. -->

objects applied before prepare() is called, you'd need to move
servlet-config interceptor up.
This stack also excludes from the normal validation and workflow
the method names input, back, and cancel. These typically are
associated with requests that should not be validated.
