Windows下的Highcharts-Export Server 2.0.1错误

Question

编辑:解决方案是将所有与phatomJS相关的脚本放入Scripts目录,并确保没有任何项目是Windows的只读.我的脚本和phantomjs.exe都存在于:C:\jetty-distribution-9.0.0.M3\webapps\ROOT\Scripts\phantomjs.

该app.properties文件具有以下配置:

# location of the phantomjs executable, could be for example /usr/local/bin/phantomjs
exec = C:/jetty-distribution-9.0.0.M3/webapps/ROOT/Scripts/phantomjs/phantomjs.exe
# location of convert script used by phantomjs, optional to leave the script property empty, than it's using the script located in: /WEB-INF/phantomjs/highcharts-convert.js. This is tested in TOMCAT, but specify a path if resource loading isn't working with the classloader (f.e. with Jetty server), script = a/path/to/my/phantomjs-script.js
script = C:/jetty-distribution-9.0.0.M3/webapps/ROOT/Scripts/phantomjs/highcharts-convert.js

我现在可以通过这里加载的demo导出http://localhost:8080/highcharts-export/demo,也可以通过我们的网站使用它来调用它url: 'http://localhost:8080/highcharts-export/'

编辑: 有没有人有一个工作的app.properties文件在Windows和Jetty下工作？

我通过对app.properties进行此修改来解决下面列出的一些问题:

# location of the phantomjs executable, could be for example /usr/local/bin/phantomjs
exec = "C:\\jetty-distribution-9.0.0.M3\\webapps\\ROOT\\Scripts\\phantomjs\\phantomjs.exe"

# location of convert script used by phantomjs, optional to leave the script property empty, than it's using the script located in: /WEB-INF/phantomjs/highcharts-convert.js. This is tested in TOMCAT, but specify a path if resource loading isn't working with the classloader (f.e. with Jetty server), script = a/path/to/my/phantomjs-script.js
script = /WEB-INF/phantomjs/highcharts-convert.js

exec值的其他变体具有相同的结果:

C:\\jetty-distribution-9.0.0.M3\\webapps\\ROOT\\Scripts\\phantomjs\\phantomjs.exe
C:/jetty-distribution-9.0.0.M3/webapps/ROOT/Scripts/phantomjs/phantomjs.exe
C:\jetty-distribution-9.0.0.M3\webapps\ROOT\Scripts\phantomjs\phantomjs.exe

我现在可以通过http://localhost:8080/highcharts-export/demo看看码头的输出来获得演示了我充斥着类似的东西:

        [ERROR] [pool-1-thread-1 02:55:19] (TaskUtils.java:handleError:95) Unexpected error occurred in sche

下面的原始问题: 这是对这个问题的跟进.我现在可以成功(至少根据maven)构建最新的highcharts-export服务器.我只修改了app.properties文件,如下所示:

# location of the phantomjs executable, could be for example /usr/local/bin/phantomjs
exec = C:/jetty-distribution-9.0.0.M3/webapps/ROOT/Scripts/phantomjs

无论phatomjs的位置配置如何,我都会得到下面列出的错误.

但是,当我将它加载到jetty时,我收到以下错误,无法解决此问题.

Answer 1

你得到了一个Beancreation异常,因为@PostConstruct afterBeanInit方法失败了.

当您将app.properties文件中的'script'属性保留为空时,它会尝试使用ClassLoader加载highcharts-convert文件.看到这里.

如app.properties文件中所述,这仅在Tomcat中进行测试.显然,Jetty的开箱即用.也许,因为ClassLoader是不同的,或者你可能必须将应用程序部署为爆炸战争？

但简单的方法是在app.properties文件中指定'script'属性.请注意,highcharts-convert.js脚本使用的必备文件也必须存在于同一文件夹中.

代码示例属性文件,由我在带有Jetty的Windows下使用.

#### phantomjs properties ####

# the host and port phantomjs listens to
host = 127.0.0.1
port = 7777

# location of the phantomjs executable, could be for example /usr/local/bin/phantomjs
exec = phantomjs

# location of convert script used by phantomjs, optional to leave the script property    empty, than it's using the script located in: /WEB-INF/phantomjs/highcharts-convert.js. This is tested in TOMCAT, but specify a path if resource loading isn't working with the classloader (f.e. with Jetty server), script = a/path/to/my/phantomjs-script.js
script = C:/Users/gert/SRC/highcharts.com/exporting-server/java/highcharts-export/target/highcharts-export/WEB-INF/phantomjs/highcharts-convert.js

在我更改了app.properties文件后,我用它构建了战争 mvn clean package

并将war文件复制到Jetty webapps文件夹.它起作用了.
