BeanIO is an open source Java framework for reading and writing Java beans or plain old java objects POJOs from a flat file or stream. Mapping file property substitution support using the syntax property. Name or property. Name,default. A new occurs attribute for specifying both min. Occurs and max. Occurs. Examples 0 1, 1, 3. Since 2. 0. 1 Since 2. Field trim logic fixed gc. Fixed OSGi class loading issues that may result in a Null. Pointer. Exception gc. Segments now support a lazy attribute to prevent class instantiation during unmarshalling. Collections wrapped by a nillable segment will be unmarshalled as null instead of an empty. XML streams. The last field in a fixed length record may be of variable length and unpadded by setting. The null character can be escaped in property values using 0. Added a keep. Padding field attribute to instruct Bean. IO not to unpad a fixed. Since 2. 0. 3 Support for record identification based on record length gc. Fixed a bug introduced in 2. Fixed property substitution for property configuration elements gc. Fixed unmarshalling logic that invoked setter methods with null for missing. Since 2. 0. 4 Added support for segments and fields of indeterminate length in the middle of a record gc. Renamed target attributes now deprecated to value for record and group definitiions. Added support for a group value attribute to return a child component. Added ignore. Unidentified. Records attribute to stream configuration gc. Fixed EOF validation for minimum record occurrences gc. Fixed several other issues see changelog. Release 2. 0 is not backwards compatible with prior releases. Sorry. This section contains the. Java Changes. The org. Bean. Reader. Context class was renamed. Record. Context in order. The exception classes org. Bean. Reader. Exception and org. Bean. Writer. Exception. The exception classes. Bean. Reader. IOException and org. Bean. Writer. IOException are now only thrown. Razor1911 Rar Skyrim more. IOException, or when a Bean. ReaderWriter method. The org. beanio. stream. Record. Reader.

All type handlers and Spring related classes are unchanged or backwards compatible. Internal implementation classes have been moved to the org. API. may change in any release without further regard to backwards compatibility. Mapping File Changes. The mapping file namespace has changed to http www. Release 2. 0 includes more lenient defaults for some mapping components. A new stream attribute. If strict is set. A default order is calculated for groups and records that do not have order explicitly set, based. CSV, delimited and fixed length record elements will use default min. Length and max. Length settings. If strict is false, release 2. Length to 0 and. max. Length to unbounded. The ordered attribute has been removed from a stream. Since release 2. 0, all record and group. The order attribute is still supported. If you want to continue validating record order, you can set order. Bean. IO calculate. The reader and writer elements have been combined into a single parser element. Format specific property names have not changed. If you have overridden the default Record. Reader. Factory or. Record. Writer. Factory, you will need to modify your class to implement. Record. Parser. Factory instead. The min. Occurs attribute for a record now defaults to 0, instead of 1. All bean elements should be renamed segment. A segment element supports. For XML formatted streams, the min. Occurs attribute for a beansegment, or a field. XML element, will always default to 1. Prior to release 2. Occurs. defaulted to 0 if not nillable. This is now consistent with XML Schema and hopefully simpler to remember. The. Occurs attribute for a field bound to an XML attribute remains 0. The xml. Wrapper attribute has been removed. XML wrappers can be replaced by segment components. Mapping file changes are illustrated using an example in Appendix C. If desired, Bean. IOs default min. Occurs value for a group, record or field can be. See Section 7. 0 Configuration. To get started with Bean. IO, download the latest stable version from. Google Code, extract the contents of the ZIP file. Bean. IO requires a version 1. JDK or higher. In order to process XML formatted streams. Bean. IO also requires an XML parser based on the Streaming API for XML St. AX, as specified by. JSR 1. 73. JDK 1. St. AX implementation and therefore does not require any additional libraries. JDK 1. 5 users. will need to include the following The St. AXJSR 1. 73 API JAR, available from Project SJSXP. A St. AX implementation JAR. A reference implementation, used for Bean. IO development and included. JDK 1. 6, is available from Project SJSXP. Alternatively, Maven users can declare the following dependencies. POM. Note that the version numbers used below are only examples. Bean. IO dependency. Id org. beaniolt group. Id. lt artifact.

Id. lt version 1. This section explores a simple example that uses Bean. IO to read and write. Lets suppose the file is in CSV format. Position. Field. Format. First Name. Text. Last Name. Text. 2Job Title. Text. 3Salary. Number. Hire Date. Date MMDDYYYYA sample file is shown below. Joe,Smith,Developer,7. Jane,Doe,Architect,8. Jon,Anderson,Manager,8. Next, lets suppose we want to read records into the following Java bean for further processing. Remember that a Java bean must have a default no argument constructor and public getters and setters. Date. public class Employee. String first. Name. String last. Name. String title. int salary. Date hire. Date. Bean. IO uses an XML configuration file, called a mapping file, to define how bean objects are bound. Below is a mapping file, named mapping. Employee objects. The. same mapping file can be used to write, or marshall, Employee objects to a file. XMLSchema instance. Locationhttp www. File formatcsv. Employee. Name. lt field namelast. Name. lt field nametitle. Date formatMMddyyyy. To read the employee CSV file, a Stream. Factory is used to load our mapping. Bean. Reader instance.
