java - Jasper Report用Struts2框架生成RTF格式

Question

我的案例与案例非常相似: Jasper Report with Struts2 Framework

一切正常并生成 PDF 文件。代码相似，配置 struts.xml 也相似，或者说是一样。

我尝试生成RTF 格式 的报告。这很简单，对吧？只需替换struts.xml中的一行--> <param name="format">RTF</param> .

API 表示:

Format - the format in which the report should be generated. Valid values can be found in JasperReportConstants.

在 JasperReportConstants 下有“FORMAT_RTF”。这意味着该值为“RTF”。没有其他的。或者...我错过了什么吗？

系统生成带有“rtf”扩展名的pdf文档，而不是真正的RTF格式文档。

怎么了？我错过了什么？

Answer 1

我希望您使用的是 itext 和 jasper Repot 的正确且兼容的 jar。 <param name="format">RTF</param>是 RTF 的唯一变化。

这是工作示例

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

如果您使用与 Jasper Report with Struts2 Framework 相同的代码那么你需要更改代码。因为在该代码中，他们以 pdf 格式导出。

你可以使用

 try {
        JasperCompileManager.compileReportToFile(
                "C:\\Users\\Parth\\workspace1\\serializ\\jasper/our_jasper_template.jrxml", 
                "H:\\jasper/our_compiled_template.jasper");
    } catch (Exception e) {
        e.printStackTrace();
        return ERROR;
    }

JasperAction.java

 package com.common;

 import java.util.ArrayList;
 import java.util.List;
 import net.sf.jasperreports.engine.JasperCompileManager;
 import com.Person;
 import com.opensymphony.xwork2.ActionSupport;

 public class JasperAction extends ActionSupport{

private static final long serialVersionUID = 1L;
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(
                "C:\\Users\\Parth\\workspace1\\serializ\\jasper/our_jasper_template.jrxml", 
                "H:\\jasper/our_compiled_template.jasper");
    } catch (Exception e) {
        e.printStackTrace();
        return ERROR;
    }

    return SUCCESS;
  }

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

Person.java

 package com;

  public class Person {
 private Long id;
 private String name;
 private String lastName;
 public Person() {
    }
  public Person(String name, String lastName) {
    this.name = name;
    this.lastName = lastName;
  }
  public Person(Long id, String name, String lastName) {
    this.id = id;
    this.name = name;
    this.lastName = lastName;
  }
public Long getId() {
    return id;
}
public void setId(Long id) {
    this.id = id;
}
public String getName() {
    return name;
}
public void setName(String name) {
    this.name = name;
}
public String getLastName() {
    return lastName;
}
public void setLastName(String lastName) {
    this.lastName = lastName;
}

}
