问题
I have a Spring web project that uses Maven to compile/build. There is no issue in building the project. I am trying to run the project in Eclipse (3.3.2) on Tomcat (v6) server.
As part of Spring project, I have a spring-servlet.xml file in WEB-INF directory. This file includes another resource xml file that has datasource configuration.
<import resource="classpath:${datasourceInclude}.xml"/>
Now when the project is compiled using Maven, it resolves the variable ${datasourceInclude} and set it with appropriate values resulting in spring-servlet.xml with proper values.
<import resource="classpath:datasourceLocal.xml"/>
But when I tried running the project in Eclipse (Tomcat), I am getting following error:
org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Failed to import bean definitions from URL location [classpath:${datasourceInclude}.xml]
Offending resource: ServletContext resource [/WEB-INF/spring-servlet.xml]; nested exception is org.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from class path resource [${datasourceInclude}.xml]; nested exception is java.io.FileNotFoundException: class path resource [${datasourceInclude}.xml] cannot be opened because it does not exist
at org.springframework.beans.factory.parsing.FailFastProblemReporter.error(FailFastProblemReporter.java:68)
...
...
Basically when I starts Tomcat, it tries to pick the spring-servlet.xml from /src/main/webapp/WEB-INF folder which has ${datasourceInclude} variable.
Can anyone tell me how to fix this issue so that I dont have to change spring-servlet.xml and add hard code value in place of ${datasourceInclude} variable.
回答1:
Try to add war:inplace to the list of goals executed for resource filtering in the Maven project configuration page.
Right-click on your project, then go to Properties > Maven > Lifecycle Mapping and add war:inplace to the Goals to invoke on resource changes as shown below:
回答2:
Who's responsible for resolving the property/variable name in your Spring XML? This is done at compile time via Maven or is it supposed to happen at runtime? If at runtime, are you using Spring's PropertyPlaceholderConfigurer?
