批管理控制台-使用InternalResourceViewResolver而不是FreeMarkerViewResolver的DispatcherServlet [英] batch admin console - DispatcherServlet using InternalResourceViewResolver instead of FreeMarkerViewResolver
问题描述
我在将spring batch管理控制台集成到我的应用程序时遇到问题.
I have an issue with integrating the spring batch admin console into my application.
好消息是，当我转到 http://mymachine.com:8080/ReportingManager时/batch/configuration 我可以进入管理控制台.
The good news is that when i go to http://mymachine.com:8080/ReportingManager/batch/configuration I can get to the admin console.
但是当我转到 http://mymachine.com:8080/ReportingManager/batch/job-configuration 我得到404和一个错误，提示找不到/batch/jobs.
But when I go to http://mymachine.com:8080/ReportingManager/batch/job-configuration i get a 404 and an error saying that /batch/jobs can't be found.
我刚刚完成了比较我的应用程序日志和我知道正在运行的spring-batch-admin-sample应用程序之间的org.springframework.web日志输出差异的练习.
I've just gone through the exercise of comparing the difference in output of org.springframework.web logs between my application logs and the spring-batch-admin-sample application which I know is working.
查看日志后，似乎可以在spring batch管理控制台中找到URL映射，但是DispatcherServlet尝试使用InternalResourceViewResolver代替FreeMarkerViewResolver
After looking at the logs it looks like the URL mappings can be found for the spring batch admin console but the DispatcherServlet is trying to use InternalResourceViewResolver instead of the FreeMarkerViewResolver
我的以下应用日志显示错误的ViewResolver用于/ReportingManager/batch/jobs ...
My application logs below show the wrong ViewResolver is being used for /ReportingManager/batch/jobs...

当我查看spring-batch-admin-sample的需求时，我可以看到/spring_admin_console/jobs正在使用AjaxFreeMarkerView ...
Whereas when I look at the longs for the spring-batch-admin-sample I can see that /spring_admin_console/jobs is using AjaxFreeMarkerView...

我花了一段时间试图找出正在发生的事情，并且不确定.我怀疑我的web.xml可能做错了什么.可能与servlet的顺序有关.
I've spent a while trying to find out what is happening and am not sure. I suspect maybe I am doing something wrong in my web.xml. Maybe relating to the order of the servlets.
我要从我的web.xml中摘录，希望有人能看到我做错了事.
I am going to post an excerpt from my web.xml in the hopes that someone will see something I am doing wrong.
预先感谢您对我的了解.
Thanks in advance for having a look at this for me.
我将我的web.xml放在这里.
I've put my web.xml here.
推荐答案
在您的Web项目中，请确保您具有以下文件夹结构:WEB-INF\classes\META-INF\spring\batch\override.并在此文件夹下创建一个新的.xml文件.随便命名即可.文件的内容应如下所示:
In your web project make sure you have this folder structure: WEB-INF\classes\META-INF\spring\batch\override. And under this folder create a new .xml file. Name it whatever name you want. The content of the file should be something like this:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
<bean id="resourceService" class="org.springframework.batch.admin.web.resources.DefaultResourceService">
<property name="servletPath" value="/batch" />
</bean>
</beans>
servletPath的值需要与web.xml中的servlet-mapping相匹配.我使用了/batch，因为这就是您所拥有的.
The value for the servletPath needs to match your servlet-mapping in your web.xml. I used /batch because this is what you have in yours.
此处的更多信息.另外，查看.您需要搜索名为resourceService的bean，看看
More about this here. Also, it does help to have a look at the Spring Batch Admin source code. In that resources-context.xml you can see that a certain SPeL expression is used for various servletPath resources: <prop key="servletPath">#{resourceService.servletPath}</prop>. You need to search for the bean called resourceService, have a look at its source code and from there you can establish what property to change for DefaultResourceService in your custom .xml file.
最新编辑:作为一般建议，您的mvc-dispatcher DispatcherServlet将自动拾取，默认情况下将拾取位于/WEB-INF/mvc-dispatcher-servlet.xml的文件.您将在两个不同的应用程序上下文中将mvc-dispatcher-servlet.xml下的bean拾取并加载两次，因为您已将此文件指定为contextConfigLocation值之一.那里有一个上下文层次结构，根目录(由contextConfigLocation定义)是父目录.这个想法是将非Web的(或将由Web使用的)bean放在根上下文中，并且Web能够使用"这些bean.其他方法不太有意义，因为DAO或Service类不需要访问Web.
LATER EDIT: As a general suggestion, your mvc-dispatcher DispatcherServlet is picking up automatically and by default the file located at /WEB-INF/mvc-dispatcher-servlet.xml. You'll have the beans under mvc-dispatcher-servlet.xml being picked up and loaded twice in two different app contexts because you have this file specified as one of the contextConfigLocation values. There is a hierarchy of contexts there, root one (defined by contextConfigLocation) being the parent. The idea is to place beans that are non-web (or that are to be used by web) in the root context and the web to be able to "use" these beans. Other way around doesn't quite make sense, because a DAO or Service class doesn't need access to web.
