Action常见注解的运用

 1 @ParentPackage()用于定义一个包名,如:@ParentPackage(“mypk”)
 2 
 3 @Namespace()用于定义一个命名空间,如:@Namespace("/")
 4 
 5 @Action用于定义一个一个action,如:@Action(value="login"),此注解中还存在results,用于返回一个地址,如:
 6    @Action(value = "testFileUpload", interceptorRefs = {
 7             @InterceptorRef("myfileUpload"), @InterceptorRef("defaultStack") }, results = {
 8             @Result(name = "input", location = "/admin/upload.jsp"),
 9             @Result(name = "success", location = "/admin/index.jsp") })
10   其中interceptorRefs属性用于引入拦截器
11 
12 注1:使用struts版本下载配置的action,注意参数的配置:
13   @Action(value="download",results={
14               @Result(name="success",type="stream",params={
15                       "inputName","input",
16                       "contentDisposition","attachment;filename=文件名称",
17                       "contentType","application/x-msdownload",
18                       "bufferSize","4096"})
19       })
20 
21 注2:上传时配置的action,注意参数的配置:
22   @Action(value=”fileUpload”,interceptorPefs={@InterceptorRef(value=”myUplaod”,params={“maximumSize”,”1024000”,”allowTypes”,”image/pjpeg”}),@InterceptorRef(value=”ddd”)},reuslt={@Result(name = "success", location = "/admin/index.jsp") }})
23   
24 @Validations用于验证注解,如:
25 @Validations(requiredString={@RequiredStringValidator(fileName=”uname”,message=”值”)})
26 
27 @SkipVaidation用于跳过验证注解
28

30 以上是action常用的注解。。。通常情况下,struts的注解与它的xml配置文件配合使用。。。
