Utilize Maven 2 JasperReports Plugin to Compile jrxml Automatically

Motivation
We would like to compile jrxml automatically as we build our web application.


Mechanics
We use Maven 2 JasperReports Plugin to compiles JasperReports xml design files to Java source and .jasper serialized files.

How to do it
1. edit nig-web/pom.xml

Refactoring: Decompose Conditional

Motivation

if-else條件判斷式,一直是程式看起來很複雜的地方。當功能更複雜,條件式就會更多,判斷式就會顯得又臭又長。無論是程式的可讀性,或是可維護性,都大大的降低。另外,在測試的時候(如code coverage test),也會增加測試時間。


Mechanics
  • 將condition 的部份extract到獨立的method.
  • 將if-else的部份,extract到獨立的method.

Example

Before Refactor


 public List doPrint(String evdcCdStart, String evdcCdEnd) throws FDCDataAccessException {  
      List params = new ArrayList();  
      StringBuffer sql = new StringBuffer();  
      sql.append(" SELECT EVADE_CD, EVADE_NM FROM Nigt042 ");  
      String where = " WHERE ", and = " ";  
      if(StringUtils.isNotEmpty(evdcCdStart) && StringUtils.isNotEmpty(evdcCdEnd)){  
           sql.append(where).append(and).append(" EVADE_CD between ?1 and ?2 ");  
           params.add(evdcCdStart);  
           params.add(evdcCdEnd);  
           where = " ";  
           and = " AND ";  
      }else if(StringUtils.isNotEmpty(evdcCdStart) && StringUtils.isEmpty(evdcCdEnd)){  
           sql.append(where).append(and).append(" EVADE_CD >= ?1 ");  
           params.add(evdcCdStart);  
           where = " ";  
           and = " AND ";  
      }else if(StringUtils.isEmpty(evdcCdStart) && StringUtils.isNotEmpty(evdcCdEnd)){  
           sql.append(where).append(and).append(" EVADE_CD <= ?1 ");  
           params.add(evdcCdEnd);  
           where = " ";  
           and = " AND ";  
      }  
      sql.append(" ORDER BY EVADE_CD ");  
      return Nigt042Dao.queryNativeSQL(new Nigt042(), sql.toString(), params.toArray());  
 }  

從上述code snippet可以看出有三段判斷式

判斷式1: StringUtils.isNotEmpty(evdcCdStart) && StringUtils.isNotEmpty(evdcCdEnd)

判斷式2: StringUtils.isNotEmpty(evdcCdStart) && StringUtils.isEmpty(evdcCdEnd)

判斷式3: StringUtils.isEmpty(evdcCdStart) && StringUtils.isNotEmpty(evdcCdEnd)

為了讓if-else邏輯判斷增加可讀性,分別將此三的判斷式抽離成三個private method,並賦予有意義的名字,此三個method分別為:

before extract after extract
StringUtils.isNotEmpty(evdcCdStart) && StringUtils.isNotEmpty(evdcCdEnd) hasStartAndEndCode
StringUtils.isNotEmpty(evdcCdStart) && StringUtils.isEmpty(evdcCdEnd) onlyHasStartCode
StringUtils.isEmpty(evdcCdStart) && StringUtils.isNotEmpty(evdcCdEnd) onlyHasEndCode



After Refactor


 public List doPrint(String evdcCdStart, String evdcCdEnd) throws FDCDataAccessException {  
      List params = new ArrayList();  
      StringBuffer sql = new StringBuffer();  
      sql.append(" SELECT EVDC_CD, EVDC_NM FROM NIGT042 ");  
      String where = " WHERE ", and = " ";  
      if(hasStartAndEndCode(evdcCdStart, evdcCdEnd)){  
           sql.append(where).append(and).append(" EVDC_CD between ?1 and ?2 ");  
           params.add(evdcCdStart);  
           params.add(evdcCdEnd);  
           where = " ";  
           and = " AND ";  
      }else if(onlyHasStartCode(evdcCdStart, evdcCdEnd)){  
           sql.append(where).append(and).append(" EVDC_CD >= ?1 ");  
           params.add(evdcCdStart);  
           where = " ";  
           and = " AND ";  
      }else if(onlyHasEndCode(evdcCdStart, evdcCdEnd)){  
           sql.append(where).append(and).append(" EVDC_CD <= ?1 ");  
           params.add(evdcCdEnd);  
           where = " ";  
           and = " AND ";  
      }  
      sql.append(" ORDER BY EVDC_CD ");  
      return nigt042Dao.queryNativeSQL(new Nigt042(), sql.toString(), params.toArray());  
 }  
 private boolean onlyHasEndCode(String evdcCdStart, String evdcCdEnd) {  
      return StringUtils.isEmpty(evdcCdStart) && StringUtils.isNotEmpty(evdcCdEnd);  
 }  
 private boolean onlyHasStartCode(String evdcCdStart, String evdcCdEnd) {  
      return StringUtils.isNotEmpty(evdcCdStart) && StringUtils.isEmpty(evdcCdEnd);  
 }  
 private boolean hasStartAndEndCode(String evdcCdStart, String evdcCdEnd) {  
      return StringUtils.isNotEmpty(evdcCdStart) && StringUtils.isNotEmpty(evdcCdEnd);  
 }

[Java] VarArgs 的應用


Varargs
varargs是JDK 1.5開始才提供的新功能,其定義如下:The varargs, or variable arguments, feature allows a developer to declare that a method can take a variable number of parameters for a given argument. The vararg must be the last argument in the formal argument list.
白話一點來說,varargs就是用來處理輸入參數數量無法預知的情形,以下是一個簡單的範例。
Scenario
為了因應客戶需求,將前端的刪除功能從單筆變成多筆,此時要從前端傳多筆資料的primary key給controller來進行資料刪除。

Class Diagram
由於多筆刪除是統一的作法,且每一個Controller都會繼承Abstract Controller,於是就把getPKList定義於AbstractController中,這樣每個controller都可以直接取用,如下圖:



Sequence Diagram
從Sequence diagram可以看出,當使用者選擇某幾筆資料,然後按下刪除按鈕,Controller會呼叫getPKList來取得從前端回傳回來的primary key,當接收到以後,再呼叫doDelete來刪除資料。


Sample Code
從以下的code snippet可以看出,getPKList有帶兩個參數,第二個參數就是varargs,由於每張table擁有的primary key的數量不一,有可能一個或一個以上,如NIGT036只有一個primary key, NIGT001則有四個
NIGT036

NIGT001



透過varargs,就可以一個method 滿足所有controller 的需求

ReportWrapper Class for JasperReport Implementation

在JasperReport開發,主要會分成五個部分:
  1. Get data source: 傳入List of value object,並建立JRBeanCollectionDataSource
  2. Read Jasper File: 讀取.jasper file
  3. Generate JasperPrint: 讀取report input stream並建立JasperPrint物件
  4. Set response content type and header: 根據user要輸出的格式,指定content type and header
  5. Export Report: 根據user要輸出的格式,用相對應的API進行報表輸出


其實每份報表都不外乎這五大步驟,這邊我建立一個ReportWrapper class,如下


 package gov.fdc.nig.report;

 */  
 private @ResponseBody  
 void processF7Key(final NIG135DataBean formBean,  
 final HttpServletResponse response, final HttpSession session)  
 throws IllegalAccessException, InvocationTargetException,  
 IOException {  
      String jasperXMLFileName = "NIG135P1";  
      OutputStream outputStream = response.getOutputStream();  
      try {  
           if ("135".equals(formBean.getReportOption())) {  
                Map params = new HashMap();  
                params.put("rejectPeriod", formBean.doPrintForNIG135P1(covertToNIG135P1ReportBean(formBean));  
                if ("1".equals(formBean.getReportType())) {  
                     // export csv file  
                     if (ExportFormatEnum.CSV.getValue().equals(  
                     formBean.getExportFormat())) {  
                          new ReportWrapper().execute(data,  
                          jasperXMLFileName, params, response,

                     }  
                          // export pdf file  
                          else if (ExportFormatEnum.PDF.getValue().equals(  
                          formBean.getExportFormat())) {

                     }  
                }  
           }  
      }catch(Exception e){  
      //............  
      }  
 }  

nig.nig135w.js
 function nig135wFormF7(){  
      $("#fn").val("7");  
      $("#nig135wForm").attr("target", "_self");  
      $("#nig135wForm").attr("action", "/nig/front/NIG135W");  
      $("#nig135wForm").submit();  
 }  

Benefits
所有的報表程式,都透過這一支ReportWrapper class來處理。
我們只要專注於前端的business logic以及templates,後端如何去產生pdf, csv等格式,就交給ReportWrapper 處理就好。

How to Access .jasper file from EAR File


Problem
根據標準組所提供的讀取.jasper的方式,是將.jasper的目錄寫死,此寫法未來會有很大的問題。如:
1. 若有多位開發人員同時進行開發,大家都存放於不同的地方,會導致某人的環境可以執行,其他人卻無法執行的狀況。
2. 若開發機、測試機、正式機所放置的目錄不一樣,這樣deploy到不同的機器,又忘記手動去更改目錄,會導致在測試機可以執行,正式機卻無法執行的窘境。

為了改善上述的潛在問題,以下是解決方式:

File Structure
My ReportWrapper class is under gov.fdc.nig.report

.japser files are under resources/report


After we build our application to ear file, the file structure looks like this:


Source Code

1
2
3
4
5
    private final static String JASPER_CLASSPATH = "..\\..\\..\\..\\report\\templates\\";
    InputStream reportStream
     = getClass().getResourceAsStream(JASPER_CLASSPATH.concat(fileName.concat(".jasper")));
    JasperReport report = (JasperReport) JRLoader.loadObject(reportStream);
    


Benefit
透過上述的寫法,採相對路徑的方式來讀取.jasper file,避免上述的問題

How to Write CSV Files as UTF-8 for Excel

Problem
As JasperReport export CSV file with UTF-8 encoding, Microsoft Excel wasn't displaying a CSV (comma separated values) file correctly.
The screenshot is as bellows:

But it can display correctly for notepad:


Root Cause
In the absence of any charset identification, Excel must guess about a file's content encoding. Therefore, Excel uses that default to read and display CSV files.


Solution
Use the byte-order marker (BOM) to identify the CSV file as a Unicode file. So I write an byte array into OutputStream, then Excel should uses UTF-8 read and display CSV files.

  //byte-order marker (BOM)
  byte b[] = {(byte)0xEF, (byte)0xBB, (byte)0xBF};
  //insert BOM byte array into outputStream
  outputStream.write(b);
  JRExporter csvExporter = new JRCsvExporter();
  csvExporter.setParameter(JRExporterParameter.JASPER_PRINT, print);
  csvExporter.setParameter(JRExporterParameter.OUTPUT_STREAM, outputStream);
  csvExporter.setParameter(JRExporterParameter.OUTPUT_FILE_NAME, reportName.concat(".csv"));
  csvExporter.setParameter(JRExporterParameter.CHARACTER_ENCODING, "UTF-8");
  csvExporter.exportReport();

利用Commons Lang API 來提升Code Coverage

Problem
目前參與的專案,對於code coverage有相當嚴苛的規定(at least 80%),在進行測試的時候,發現由Eclipse產生的equals()與hashCode()此二method是無法提升到80%以上的主因,因為裡頭太多的if-else statement,如下:

Solution
透過Apache Commons Lang的HashCodeBuilder與EqualsBuilder來解決此問題。


Steps
1. 建立一個Domain Base Class,裡頭透過Commons Lang的API來進行實作hashCode與equals method
實作內容很簡單,如下:

   package gov.fdc.nig.domain;
   
   import org.apache.commons.lang.builder.CompareToBuilder;
   import org.apache.commons.lang.builder.EqualsBuilder;
   import org.apache.commons.lang.builder.HashCodeBuilder;
   import org.apache.commons.lang.builder.ToStringBuilder;
   
   public class DomainBase {
   
       /*
        * This class enables a good hashCode method to be built for any class.
        * It follows the rules laid out in the book Effective Java by Joshua Bloch.
        * Writing a good hashCode method is actually quite difficult.
        * This class aims to simplify the process.
        * (non-Javadoc)

       public int hashCode() {
           return HashCodeBuilder.reflectionHashCode(this);
       }
   
       /*

        * It follows rules laid out in Effective Java , by Joshua Bloch.
        * In particular the rule for comparing doubles, floats, and arrays can be tricky.
        * Also, making sure that equals() and hashCode() are consistent can be difficult.
        * (non-Javadoc)
        * @see java.lang.Object#equals(java.lang.Object)
        */
       public boolean equals(Object obj) {
           return EqualsBuilder.reflectionEquals(this, obj);
       }
   
       /*
        * Assists in implementing Comparable.compareTo(Object) methods.
        * It is consistent with equals(Object) and hashcode() built with EqualsBuilder and HashCodeBuilder.
        */
       public int compareTo(Object obj) {
           return CompareToBuilder.reflectionCompare(this, obj);
       }
   
       /*
        * Assists in implementing Object.toString() methods.
        *
        * (non-Javadoc)
        * @see java.lang.Object#toString()
        */
       public String toString() {
           return ToStringBuilder.reflectionToString(this);
       }
   
   }



2. 原本的entity class,先繼承DomainBase,再來刪除不必要的equals, hashCode與toString method,通通交給DomainBase處理即可。class之間的關係如下:
