Question

我正在尝试通过遵循教程来配置带有Struts2的Jasper。但是当我运行我的应用程序时出现以下错误。

net.sf.jasperreports.engine.JRException：java.io.FileNotFoundException：Struts2Example / jasper / our_jasper_template.jrxml（没有这样的文件或目录）

我已经在网上搜了好几个小时，但我无法找到解决问题的方法。任何人都可以帮我解决这个问题。我的代码如下。

<struts>
    <package name="default" namespace="/" extends="jasperreports-default">
        <action name="myJasperTest"     class="com.dilan.user.action.JasperAction">
            <result name="success" type="jasper">
                <param name="location">/jasper/our_compiled_template.jasper</param>
                <param name="dataSource">myList</param>
                <param name="format">PDF</param>
            </result>
        </action>
    </package>
</struts>

我的动作类

  package com.dilan.user.action;
  import com.opensymphony.xwork2.ActionSupport;
  import net.sf.jasperreports.engine.JasperCompileManager;

  import java.util.ArrayList;
  import java.util.List;

public class JasperAction extends ActionSupport {

private List<Person> myList;

public String execute() throws Exception {

    // Create some imaginary persons.
    Person p1 = new Person(new Long(1), "Patrick", "Lightbuddie");
    Person p2 = new Person(new Long(2), "Jason", "Carrora");
    Person p3 = new Person(new Long(3), "Alexandru", "Papesco");
    Person p4 = new Person(new Long(4), "Jay", "Boss");

    // Store people in our dataSource list (normally they would come from a database).
    myList = new ArrayList<Person>();
    myList.add(p1);
    myList.add(p2);
    myList.add(p3);
    myList.add(p4);

    try {
        JasperCompileManager.compileReportToFile(
                "Struts2Example/jasper/our_jasper_template.jrxml",
                "Struts2Example/jasper/our_compiled_template.jasper");
    } catch (Exception e) {
        e.printStackTrace();
        return ERROR;
    }
    return SUCCESS;
}

public List<Person> getMyList() {
    return myList;
}

}

我已按照本教程创建我的应用程序。 http://struts.apache.org/docs/jasperreports-tutorial.html

下面我附上了我的项目结构图片。有人可以帮我解决这个问题......！ Project structure

使用Struts2配置Jasper时找不到jrxml
