使用注解配置struts2action用于文件上传
@Controller()
@Namespace("/clientAccept")
public class ClientAcceptAction{
//get set方法一定要加
private File luploadDoc;
private String luploadDocFileName;
// 上传资质资料
@Action(value = "toUploadLicence", results = { @org.apache.struts2.convention.annotation.Result(name = "input", type = "dispatcher", location = "/client/fileerror.jsp") }, interceptorRefs = {
@InterceptorRef(value = "fileUpload", params = {
"maximumSize",
"4194304",
"allowedTypes",
"image/bmp,image/PNG,image/gif,image/pjpeg,image/JPEG,image/JPG,image/jpg,application/msword,application/vnd.openxmlformats-officedocument.wordprocessingml.document" }),
@InterceptorRef(value = "defaultStack") })
// defaultStack
public String toUploadLicence() throws Exception {
}
}
在使用拦截器时 默认的比如自动填充 文件上传等拦截器全部都不会初始而使用 必须显示的添加 @InterceptorRef(value = "defaultStack") 默认的拦截器
同时使用 fileUpload 的配置 覆盖文件上传的拦截器 这样不影响全局的配置 只应用到该action中
比如在struts.properties配置了文件大小为60M 而该action配置的是4M 然而运行发现该拦截器 没起到作用 不知道为何
找了多方面资料 才知道 使用注解时使用到了 ActionSupport 类中的某些东西
使用注解使用拦截器时必须要继承ActionSupport 才能生效 修改为：
@Controller()
@Namespace("/clientAccept")
public class ClientAcceptAction extends ActionSupport {
//get set方法一定要加
private File luploadDoc;
private String luploadDocFileName;
// 上传资质资料
@Action(value = "toUploadLicence", results = { @org.apache.struts2.convention.annotation.Result(name = "input", type = "dispatcher", location = "/client/fileerror.jsp") }, interceptorRefs = {
@InterceptorRef(value = "fileUpload", params = {
"maximumSize",
"4194304",
"allowedTypes",
"image/bmp,image/PNG,image/gif,image/pjpeg,image/JPEG,image/JPG,image/jpg,application/msword,application/vnd.openxmlformats-officedocument.wordprocessingml.document" }),
@InterceptorRef(value = "defaultStack") })
// defaultStack
public String toUploadLicence() throws Exception {
}
}
这样就可以拦截到了
