我用谷歌搜索了如何解决它，但没有，我认为配置正确，但也许有人可以看到我的错误，请帮帮我!!

我使用struts2 jasperreports和注释。我的struts.xml

 <package name="default" extends="struts-default, jasperreports-default">
            <result-types> 
           <result-type name="jasper" class="org.apache.struts2.views.jasperreports.JasperReportsResult" /> 
   </result-types>  
   </package>

操作文件

import com.opensymphony.xwork2.ActionSupport;

import java.net.URL;
import java.util.HashMap;
import java.util.Map;
import net.sf.jasperreports.engine.JasperCompileManager;
import org.apache.struts2.convention.annotation.Action;
import org.apache.struts2.convention.annotation.Result;


public class GenerarReportesAction extends ActionSupport {
private Map<String,Object> params;
private int numsol;


       @Action(value = "imprimirVale", results = {
        @Result(name = "success", type="jasper", 
            params={"location","/Reportes/ValeAlmacen.jasper"," format", "PDF", "reportParameters","%{params}","documentName","vale_almacen.pdf"})})
    @Override
    public String execute() throws Exception {

        try {
            JasperCompileManager.compileReportToFile(
                    "Reportes/ValeAlmacen.jrxml",
                    "Reportes/ValeAlmacen.jasper");
            params = new HashMap<String,Object>();
            URL img = getClass().getClassLoader().getResource("../../img/IQFALOGO.jpg");
            params.put("img",img.toString() );

           params.put("numsol",numsol);

        } catch (Exception e) {
            e.printStackTrace();
            return ERROR;
        }

        return SUCCESS;
    }

}

Answer 1

这就是答案：

对类[类Actions.GenerarReportesAction]进行结果注释或由文件扩展名确定，或者是操作的PackageConfig的默认结果类型，无法找到为Struts / XWork包定义的结果类型[动作＃惯例默认＃]

要使用您自己的包（默认），您可以：

使用ParentPackage annotation
在struts.xml中定义struts.convention.default.parent.package
