Method Details

wrapWithDefaultGzipHandler

public static org.eclipse.jetty.server.handler.gzip.GzipHandler wrapWithDefaultGzipHandler(org.eclipse.jetty.server.Handler handler,
 int inflateBufferSize,
 int compressionLevel)

addQosFilters

public static void addQosFilters(org.eclipse.jetty.servlet.ServletContextHandler handler,
 com.google.inject.Injector injector)

Add any filters that were registered with JettyBindings.addQosFilter(com.google.inject.Binder, java.lang.String, int). These must be added first in the filter chain, because when a request is suspended and later resumed due to QoS constraints, its filter chain is restarted. Placing QoSFilters first in the chain avoids double-execution of other filters.

addExtensionFilters

public static void addExtensionFilters(org.eclipse.jetty.servlet.ServletContextHandler handler,
 com.google.inject.Injector injector)

addFilters

public static void addFilters(org.eclipse.jetty.servlet.ServletContextHandler handler,
 Set<? extends ServletFilterHolder> filterHolders)

getJettyRequestLogHandler

public static org.eclipse.jetty.server.Handler getJettyRequestLogHandler()

addAllowHttpMethodsFilter

public static void addAllowHttpMethodsFilter(org.eclipse.jetty.servlet.ServletContextHandler root,
 List<String> allowedHttpMethods)

maybeAddHSTSPatternRule

public static void maybeAddHSTSPatternRule(ServerConfig serverConfig,
 org.eclipse.jetty.rewrite.handler.RewriteHandler rewriteHandler)

maybeAddHSTSRewriteHandler

public static void maybeAddHSTSRewriteHandler(ServerConfig serverConfig,
 org.eclipse.jetty.server.handler.HandlerList handlerList)

getGuiceFilterHolder

public static org.eclipse.jetty.servlet.FilterHolder getGuiceFilterHolder(com.google.inject.Injector injector)

Using this FilterHolder forces the underlying GuiceFilter to be instantiated with the 1-argument constructor that uses an injected non-static FilterPipeline. Since the FilterPipeline is non-static, multiple Jetty servers may be initialized by separate Guice Injectors running in the same JVM. This is currently needed only for running embedded tests.
