方法详细信息

preConfigure

public void preConfigure(WebAppContext context)
                  throws Exception

从接口 Configuration 复制的描述

Set up for configuration.

Typically this step discovers configuration resources

指定者：

接口 Configuration 中的 preConfigure

覆盖：

类 AbstractConfiguration 中的 preConfigure

参数：

context - The context to configure

抛出：

Exception

configure

public void configure(WebAppContext context)
               throws Exception

从接口 Configuration 复制的描述

Configure WebApp.

Typically this step applies the discovered configuration resources to either the WebAppContext or the associated MetaData.

指定者：

接口 Configuration 中的 configure

覆盖：

类 AbstractConfiguration 中的 configure

参数：

context - The context to configure

抛出：

Exception

deconfigure

public void deconfigure(WebAppContext context)
                 throws Exception

从接口 Configuration 复制的描述

DeConfigure WebApp. This method is called to undo all configuration done. This is called to allow the context to work correctly over a stop/start cycle

指定者：

接口 Configuration 中的 deconfigure

覆盖：

类 AbstractConfiguration 中的 deconfigure

参数：

context - The context to configure

抛出：

Exception

cloneConfigure

public void cloneConfigure(WebAppContext template,
                           WebAppContext context)
                    throws Exception

从接口 Configuration 复制的描述

Clone configuration instance.

Configure an instance of a WebAppContext, based on a template WebAppContext that has previously been configured by this Configuration.

指定者：

接口 Configuration 中的 cloneConfigure

覆盖：

类 AbstractConfiguration 中的 cloneConfigure

参数：

template - The template context

context - The context to configure

抛出：

Exception

另请参见：

AbstractConfiguration.cloneConfigure(org.eclipse.jetty.webapp.WebAppContext, org.eclipse.jetty.webapp.WebAppContext)

resolveTempDirectory

public void resolveTempDirectory(WebAppContext context)

Get a temporary directory in which to unpack the war etc etc. The algorithm for determining this is to check these alternatives in the order shown:

A. Try to use an explicit directory specifically for this webapp:

1. Iff an explicit directory is set for this webapp, use it. Do NOT set delete on exit.
2. Iff javax.servlet.context.tempdir context attribute is set for this webapp && exists && writeable, then use it. Do NOT set delete on exit.

B. Create a directory based on global settings. The new directory will be called "Jetty_"+host+"_"+port+"__"+context+"_"+virtualhost Work out where to create this directory:

1. Iff $(jetty.home)/work exists create the directory there. Do NOT set delete on exit. Do NOT delete contents if dir already exists.
2. Iff WEB-INF/work exists create the directory there. Do NOT set delete on exit. Do NOT delete contents if dir already exists.
3. Else create dir in $(java.io.tmpdir). Set delete on exit. Delete contents if dir already exists.

makeTempDirectory

public void makeTempDirectory(File parent,
                              WebAppContext context,
                              boolean deleteExisting)
                       throws IOException

抛出：

IOException

unpack

public void unpack(WebAppContext context)
            throws IOException

抛出：

IOException

findWorkDirectory

public File findWorkDirectory(WebAppContext context)
                       throws IOException

抛出：

IOException

isTempWorkDirectory

public boolean isTempWorkDirectory(File tmpDir)

Check if the tmpDir itself is called "work", or if the tmpDir is in a directory called "work".

返回：

true if File is a temporary or work directory

getCanonicalNameForWebAppTmpDir

public static String getCanonicalNameForWebAppTmpDir(WebAppContext context)

Create a canonical name for a webapp temp directory. The form of the name is: "Jetty_"+host+"_"+port+"__"+resourceBase+"_"+context+"_"+virtualhost+base36_hashcode_of_whole_string host and port uniquely identify the server context and virtual host uniquely identify the webapp

返回：

the canonical name for the webapp temp directory

findJars

protected List<Resource> findJars(WebAppContext context)
                           throws Exception

Look for jars in WEB-INF/lib

参数：

context -

返回：

the list of jar resources found within context

抛出：

Exception
