为什么在 JasperServer 6.0.1 上出现调度程序无效日期错误？

Question

我正在将 jasperserver 从 3.7 迁移到 jasperserver 6.0.1，现在在新的 jasperserver 中我希望日期格式为 dd/mm/yyyy 但默认情况下日期格式为 yyyy-mm-dd。为此，我在

处更改了 jasperserver_config.properties 文件

apache-tomcat-7.0.65\webapps\jasperserver\WEB-INF\bundles\jasperserver_config.properties

我改成了

    # Used for parsing and formatting dates by server
    date.format=dd/MM/yyyy
    datetime.format=dd/MM/yyyy HH:mm:ss
    time.format=HH:mm:ss

    # Used for parsing and formatting dates by calendar component (UI).
    # Pattern for date should match appropriated pattern from server properties.
    # The format for calendar component can be combinations of the following:
    # d  - day of month (no leading zero)
    # dd - day of month (two digit)
    # o  - day of year (no leading zeros)
    # oo - day of year (three digit)
    # D  - day name short
    # DD - day name long
    # m  - month of year (no leading zero)
    # mm - month of year (two digit)
    # M  - month name short
    # MM - month name long
    # y  - year (two digit)
    # yy - year (four digit)
    calendar.date.format=dd/mm/yyyy
    calendar.datetime.format=dd/mm/yyyy HH:mm:ss
    calendar.time.format=HH:mm:ss

它更改了日期格式，但是当我要安排任何报告时，日期字段显示为无效日期（见下文）。有人可以帮助我更改在整个 jasperserver

上正常工作的日期格式吗

Answer 1

JasperReports Server 6.10 版之前存在一个错误，请参阅 bug report。我当时不得不使用解决方案#2。

解决方案#1

如果可能，更新到版本 6.10。

解决方案#2

此解决方案有点冗长，但如果两个步骤（更改源、生成优化的 js 文件）都完成，则可以正常工作：

您必须编辑 js 文件才能正常工作。使用您需要的模式。

in file /opt/jasperreports-server-cp-5.5.0a/apache-tomcat/webapps/jasperserver/scripts/scheduler/model/job.js you have to change this:

row 5

from:
  var UI_DATE_PATTERN = "YYYY-MM-DD HH:mm";
to:
  var UI_DATE_PATTERN = "DD.MM.YYYY HH:mm";
row 766

from:
data.trigger.startDate = moment(data.trigger.startDate).format(SERVICE_DATE_PATTERN);
to:
 data.trigger.startDate = moment(data.trigger.startDate,UI_DATE_PATTERN).format(SERVICE_DATE_PATTERN);

优化Java脚本

注意： 由于优化了 Java 脚本文件（据我所知这不是编辑过的文件），请记住您可能需要重新创建优化的 js 文件 - 因为优化的文件是 JRS 使用的文件。第 5 版就是这种情况。6.x 至少：

Create a working directory where you can copy JavaScript files and install and run the required scripts. In this example, the directory is called Working.

Create a subdirectory for a copy of the JavaScript files from JasperReports Server. This directory is called jssources.

Copy the following directories from the JasperReports Server directory, <js-webapp>, to js-sources:

• Copy <js-webapp>/scripts to js-sources/scripts.

• Copy <js-webapp>/fusion to js-sources/fusion (optional, Pro version only)

Back up your js-sources directory.

Create a js-optimization-output directory for the output of the optimization process.

Download and install node.js from http://nodejs.org/. Place the nodejs folder directly in your Working folder.

Download r.js, a requirejs optimization file, from http://requirejs.org and place it directly in the Working folder.

Make your changes to the JavaScript files in Working/js-sources.

Open a command line tool and run the commands to optimize the JavaScript. The following example is for Windows, it places the output in the Working/js-optimization-output folder:

% cd Working

% nodejs\node r.js -o js-sources\scripts\build.js appDir=js-sources\scripts baseUrl=. optimize=uglify2 dir=js-optimization-output

Copy the optimized scripts from js-optimization-output to <webapp>/optimized-scripts (where webapp is the location of your JRS)

Reload the web app in the app server to see the changes.

注意：如果在执行所有这些操作后出现问题，请记住清除浏览器缓存。
