构造方法详细信息

VelocityManager

public VelocityManager()

方法详细信息

setObjectFactory

public void setObjectFactory(com.opensymphony.xwork2.ObjectFactory fac)

setContainer

public void setContainer(com.opensymphony.xwork2.inject.Container container)

getVelocityEngine

public org.apache.velocity.app.VelocityEngine getVelocityEngine()

返回：

a reference to the VelocityEngine used by all struts velocity thingies with the exception of directly accessed *.vm pages

createContext

public org.apache.velocity.context.Context createContext(com.opensymphony.xwork2.util.ValueStack stack,
                                                         javax.servlet.http.HttpServletRequest req,
                                                         javax.servlet.http.HttpServletResponse res)

This method is responsible for creating the standard VelocityContext used by all WW2 velocity views. The following context parameters are defined:

• request - the current HttpServletRequest
• response - the current HttpServletResponse
• stack - the current ValueStack
• ognl - an OgnlTool
• struts - an instance of StrutsUtil
• action - the current Struts action

返回：

a new StrutsVelocityContext

init

public void init(javax.servlet.ServletContext context)

initializes the VelocityManager. this should be called during the initialization process, say by ServletDispatcher. this may be called multiple times safely although calls beyond the first won't do anything

参数：

context - the current servlet context

loadConfiguration

public Properties loadConfiguration(javax.servlet.ServletContext context)

load optional velocity properties using the following loading strategy

• relative to the servlet context path
• relative to the WEB-INF directory
• on the classpath

参数：

context - the current ServletContext. may not be null

返回：

the optional properties if struts.velocity.configfile was specified, an empty Properties file otherwise

setCustomConfigFile

public void setCustomConfigFile(String val)

setToolBoxLocation

public void setToolBoxLocation(String toolboxLocation)

getToolboxManager

public org.apache.velocity.tools.view.ToolboxManager getToolboxManager()

setChainedContexts

public void setChainedContexts(String contexts)

allow users to specify via the struts.properties file a set of additional VelocityContexts to chain to the the StrutsVelocityContext. The intent is to allow these contexts to store helper objects that the ui developer may want access to. Examples of reasonable VelocityContexts would be an IoCVelocityContext, a SpringReferenceVelocityContext, and a ToolboxVelocityContext

getVelocityProperties

public Properties getVelocityProperties()

返回：

the velocityProperties

setVelocityProperties

public void setVelocityProperties(Properties velocityProperties)

参数：

velocityProperties - the velocityProperties to set
