Release 5.1.0.20

Date: Sept 5, 2015

Juno 5.1.0.20 is a moderate update.

The biggest improvement is the ability to associate external INI config files with REST servlets using the ConfigFile functionality.

Core​

  • Significant API changes to org.apache.juneau.config API.

    • ConfigFile is now thread safe and can be shared across multiple threads.
    • New ConfigMgr class for managing configuration files.
    • Serializers and parsers can be associated with config files for storing and retrieving POJOs. Default support provided for JSON.

  • New SimpleHtmlWriter class. Can be used for simple HTML DOM construction.

  • New ProcBuilder class for calling external processes.

  • New ObjectMap.remove(Class,String,Object) method.

  • "class='link'" added to links generated by HtmlDocSerializer.

  • New EncoderGroup.append(EncoderGroup) method.

  • New HtmlDocSerializerContext.HTMLDOC_addLinks configuration property.

  • Modified the Parser.createContext(ObjectMap,Method,Object) method. Outer context objects can be passed in to create instances of non-static inner classes.

  • Fixed bug in HtmlStrippedDocSerializer where exception was thrown when trying to serialize primitive arrays.

  • JsonParser now handles parsing JSON boolean/numeric values as strings to bean properties of type boolean or number.

  • UrlEncodingSerializer and UrlEncodingParser now represent arrays and collections as key-value pairs where the keys are numbers (e.g. "?0=foo&1=bar").

  • Various internal improvements to IOPipe.

  • New ReflectionUtils.getResource(Class,String) method.

  • StringUtils.parseNumber(String,Class) now returns zero for empty strings. This affects the way most parsers handle blank values.

Server​

  • You can now parse into non-static inner classes of a servlet for parameters/attributes/content. Useful if you like to define your marshaller beans inside your servlet.

  • Changes to RestServlet:

    • New methods for accessing external INI config files: RestServlet.getConfig() RestServlet.createConfigFile()
    • New "$C{...}" variable that resolve to INI config file values.
    • New "$UE{...}" variable that URL-encodes the value inside the variable.
    • New convenience methods for retrieving classpath resource files: RestServlet.getResource(String) RestServlet.getResourceAsString(String) RestServlet.getResource(Class,String,String). Useful if you want to load predefined POJOs from JSON files in your classpath.
    • New RestServlet.handleNotFound(int,RestRequest,RestResponse) method for customized handling of when a resource or method was not found.

  • BasicRestServlet now automatically processes "/favicon.ico" requests by overriding the new ~~ RestServlet.handleNotFound(int,RestRequest,RestResponse)~~ method.

  • New RestRequest methods:

    • RestRequest.resolveVars(String)
    • RestRequest.getVarResource(String)
    • RestRequest.getConfig()

  • New RestResponse methods:

  • New RestMethod.encoders() @RestMethod(encoders) and RestMethod.inheritEncoders() annotations. Allows encoders to be fine-tuned at the method level.

  • New @RestResource(config) annotation for associating external ConfigFile config files with servlets.

  • ResourceLink.

  • New org.apache.juneau.rest.matcher package for commonly-used RestMatchers:

    • MultipartFormDataMatcher
    • UrlEncodedFormMatcher

Microservice​

  • New juneau-microservice.jar file that encapsulates all 3 juneau jars with code necessary for creating fast and efficent jetty-powered REST microservices. Contains the following:

    • Jetty 8.0
    • Apache HttpClient 4.3.5
    • Apache Commons FileUpload 1.3.1

  • Microservice now supports Java 6 (previously required Java 7)
