java - Highcharts-Export Server 2.0.1 Windows 下错误

Question

编辑:解决方案是将所有 phatomJS 相关脚本放入 Scripts 目录中，并确保没有任何项目对于 Windows 是只读的。我的脚本和 phantomjs.exe 都存在于此处:C:\jetty-distribution-9.0.0.M3\webapps\ROOT\Scripts\phantomjs。

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

我现在可以通过此处加载的演示导出http://localhost:8080/highcharts-export/demo，也可以使用 url: 'http 通过我们的网站调用它//localhost:8080/highcharts-export/'

编辑:有人有一个可以在 Windows 和 Jetty 下工作的 app.properties 文件吗？

我通过对 app.properties 进行修改解决了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

具有相同结果的 exec 值的其他变体:

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

我现在可以在 http://localhost:8080/highcharts-export/demo 上获取演示，但是查看 jetty 的输出，我被诸如此类的内容淹没:

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

原始问题如下:这是 this 的后续内容问题。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 的位置如何配置，我都会收到下面列出的错误。

但是，当我将其加载到 jetty 时，出现以下错误，并且无法解决此问题。

Answer 1

您收到 Beancreation 异常，因为 @PostConstruct afterBeanInit 方法失败。

当您将 app.properties 文件中的“script”属性留空时，它会尝试使用 ClassLoader 加载 highcharts-convert 文件。 See here 。

如 app.properties 文件中所述，这仅在 Tomcat 中进行了测试。显然，这对于 Jetty 来说并不是开箱即用的。也许，因为类加载器不同，或者也许您必须将应用程序部署为爆炸 war ？

但最简单的方法是在 app.properties 文件中指定“script”属性。请注意，highcharts-convert.js 脚本使用的强制文件也必须存在于同一文件夹中。

属性文件的代码示例，我在 Windows 下使用 Jetty 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

更改 app.properties 文件后，我使用 mvn clean package 构建 war

并将 war 文件复制到 Jetty webapps 文件夹中。它起作用了。
