我是Struts2的新手，并尝试使用fileUploader拦截器。我附加了所有代码层
动作类（FileUploadAction）
package com.caveofprogramming.actions;
import java.io.File;
import org.apache.struts2.convention.annotation.InterceptorRef;
import org.apache.struts2.convention.annotation.Action;
import org.apache.struts2.convention.annotation.Result;
import com.opensymphony.xwork2.ActionSupport;
public class FileUploadAction extends ActionSupport{
private File fileUpload;
private String fileUploadContentType;
private String fileUploadFileName;
public String getFileUploadContentType() {
return fileUploadContentType;
}
public void setFileUploadContentType(String fileUploadContentType) {
this.fileUploadContentType = fileUploadContentType;
}
public String getFileUploadFileName() {
return fileUploadFileName;
}
public void setFileUploadFileName(String fileUploadFileName) {
this.fileUploadFileName = fileUploadFileName;
}
public File getFileUpload() {
return fileUpload;
}
public void setFileUpload(File fileUpload) {
this.fileUpload = fileUpload;
}
@Action( value = "/fileUpload",
results={@Result(name="success",location="/success.jsp"),
@Result(name="error",location="/error.jsp"),
@Result(name="input",location="/error.jsp")
},
interceptorRefs={
@InterceptorRef(
params={"allowedTypes","image/jpeg,image/jpg,application/zip",
"maximumSize","1024000"},
value="fileUpload"
),
@InterceptorRef("defaultStack"),
@InterceptorRef("validation")
}
)
public String execute(){
try{
return SUCCESS;
} catch(Exception e){
return ERROR;
}
}
public String display() {
return NONE;
}
}
error.jsp文件

我不明白为什么我会收到这个错误
“内容类型不允许：fileUpload”photography-104a.jpg“”upload_37fbf440_169b_4687_af65_93c8c967256c_00000000.tmp“image / pjpeg”
虽然我上传的文件格式是“.jpg”。请帮我
您收到此错误可能是因为您不允许内容类型为image/pjpeg的文件。使用fileUpload拦截器的参数来定义允许的MIME类型
<interceptor-ref name="fileUpload">
<param name="allowedTypes">image/jpeg,image/pjpeg</param>
</interceptor-ref>
