The configuration object implementation must implement the <code>Configuration</code> interface. This + * allows for the factory to create different specializations in the future if needed and not break any application + * code. + * </p> + * <p> + * The configuration object is basically a wrapper around a properties object. The configuration is therefore specified + * as a set of properties that are loaded and processed from different sources with different precedences. It is + * important that the configuration object always be able to supply default values for any configuration properties that + * must be supplied, and not rely on the user always supplying these values.

Namely, if we put a property into a <code>Properties</code> object that already exists, the + * <code>Properties</code> object replaces it with the new value.

The basic + concept is to load a set of default properties from a known resource + file located on the class path, and then override these defaults + with optional settings that can be provided by a user through either + additional property files or via the command line (as VM arguments). + The loading of defaults from a resource property file (named <strong>com/att/cdp/default.properties</strong>) + ensures that values are defined for properties the application needs + in order to operate. + </p> + <p style="margin-left: 30.0px;"> + One of these default values that can be set is the name of the + property file that allows the user to supply settings, as well as + the path where the file can be found. In general, the default name + of the property file will be "<strong>cdp.properties</strong>", + and the path that will be searched is "<strong>${user.home};etc;../etc</strong>". + However, these values can be changed through the use of the + default.properties resource file. The property that specifies the + property file name is named <strong>com.att.cdp.bootstrap.file</strong>, + while the property named <strong>com.att.cdp.bootstrap.path</strong> + specifies the search path. + </p> + <p style="margin-left: 30.0px;"> + After the default.properties are loaded, but prior to searching for + the application configuration file, the configuration factory checks + for properties <strong>com.att.cdp.bootstrap.path</strong> and <strong>com.att.cdp.bootstrap.file + </strong>in the System properties object (meaning they were set by the + command line). If these values are defined in the system properties + object, they are used. If not, these values are obtained from the + default properties just loaded. This allows the specification of + either the file name or path, or both, to be overridden during start + up by using command-line arguments. + </p> + <p style="margin-left: 30.0px;">The search path is scanned for the + first occurrence of the specified property file. The first + occurrence is loaded and scanning is stopped at that point. The + configuration factory does not load all occurrences it finds, only + the first occurrence it finds.</p> + <p style="margin-left: 30.0px;">The configuration properties are + loaded and processed according to a defined precedence order, such + that properties defined with a higher precedence override the same + property at a lower precedence. The precedence order is defined as + follows:</p> + <h2>Precedence Order</h2> + <ol> + <li>Default properties are initially loaded into the + configuration. These default properties are the lowest level + precedence, and will be overridden by any properties specified at + higher levels. These are loaded from resources that are packaged + as part of the various application components. Each component + (Server, Coordinator, EPM, or CLI) may have different default + properties. The default properties are loaded from a resource + named <strong>com/att/cdp/default.properties</strong>. The default + properties can specify the name of the application property file + to be used to configure the application, as well as the path to + search. Additionally, these properties can be supplied via the + command line to override the default settings if needed.<br /> <br /> + </li> + <li>The configuration factory allows for the application to + supply an initial properties object to initialize the + configuration. This properties object could be loaded or created + in any way necessary for the application. This is totally up to + the application to define, if it is needed. If no + application-specific property object is supplied, this step is + skipped. If a property object is supplied, it is used to replace + or set any properties that may have been defined by the defaults.<br /> + <br /> + </li> + <li>The configuration factory will then search for a bootstrap + file on a bootstrap path. The actual bootstrap file name and path + can be specified as properties on the command line, or will + default to a file name of <strong>cdp.properties</strong> and a + path of <strong>${user.home};etc;../etc</strong>. If desired, the + user can specify the exact name of the property file to be loaded + as well as the path using <strong>-Dcom.att.cdp.bootstrap.file=<filename></strong> + and <strong>-Dcom.att.cdp.bootstrap.path=<path></strong>. + These properties are set to default values by the default + properties loaded in step #1 above. The first occurrence of a + property file is the file loaded and used. Any other occurrences + are not processed.<br /> <br /> + </li> + <li>The System properties are then merged into the + configuration. This allows the highest level of precedence, + command-line VM arguments (-D<strong>name=value</strong>) to be + merged into the configuration property object. These settings + override all lower level settings of the same name, as well as + merge all system properties into the configuration object. + </li> + </ol> + <h2>Variables</h2> + <p style="margin-left: 30.0px;"> + The configuration support allows for variables to be inserted into + any property that is defined. Variables are named using the format <strong>${name}</strong>, + where the "name" is the name of a property that is defined + in the configuration, or a system property (such as <strong>user.home</strong>). + Variables can nest, such that a variable can be replaced with + another variable, which is then reevaluated to obtain the value. + This allows for indirection as well as variable substitution, if + needed. + </p> + <h2>Using the Configuration Support</h2> + <p style="margin-left: 30.0px;"> + The configuration support was designed to be easy to use. The + configuration implementation is abstracted away from the application + so that it could be changed easily in the future if needed, or if we + needed to load different implementations for different reasons. This + means that the application always accesses the configuration through + an interface, named <strong>Configuration</strong>. The + implementation of that configuration interface is obtained by a + static method on the <strong>ConfigurationFactory</strong> class. + The configuration factory will both create the configuration if not + already created on the first access, as well as return the current + configuration if already created. Additionally, the + ConfigurationFactory provides mechanisms to recreate the + configuration after the application is initialized should the need + arise to update its configuration. + </p> + <p style="margin-left: 30.0px;">An example of the code needed to + obtain access to the configuration is:</p> + <pre style="margin-left: 30.0px;">Configuration config = ConfigurationFactory.getConfiguration();</pre> + <p style="margin-left: 30.0px;">Please refer to the javadoc or the + source code in cdp-common for other ways that the configuration and + configuration factory can be used.</p> + <h2>Reloading Properties</h2> + <p style="margin-left: 30.0px;">The configuration support allows + for properties to be re-loaded and re-evaluated after the + application is running. This is designed to allow a configuration to + be refreshed should the need arise. This could allow on-demand + refresh (via a command, for example), or automatically based on + sensing a change in the configuration file.</p> + <p style="margin-left: 30.0px;"> + When the <strong>ConfigurationFactory</strong> method <strong>getConfiguration(Propert</strong><strong>ies)</strong> + is called, the current configuration is cleared and rebuilt using + the process defined above. The supplied property object is used in + step #2 of the process. While the properties are being re-built, no + access to the properties are allowed. Any attempt to access + properties while the re-build operation is in effect will block the + caller until completed. This is accomplished using read and write + shared locks. + </p> +</body> +</html> diff --git a/app-c/appc/appc-common/src/main/java/org/openecomp/appc/encryption/EncryptionException.java b/app-c/appc/appc-common/src/main/java/org/openecomp/appc/encryption/EncryptionException.java new file mode 100644 index 000000000..c21abc2b9 --- /dev/null +++ b/app-c/appc/appc-common/src/main/java/org/openecomp/appc/encryption/EncryptionException.java @@ -0,0 +1,35 @@ +/*- + * ============LICENSE_START======================================================= + * openECOMP : APP-C + * ================================================================================ + * Copyright (C) 2017 AT&T Intellectual Property.
