    text
    copied!<p>I would like to implement properties policy in my application : i want to define default properties inside my application, and in case of, i want to keep possibility to overriding this default parameters by a config file outside of the war file. </p> <p>So i define a ConfigModule.java:</p> <pre><code>public class ConfigModule extends AbstractModule { private static final Logger LOG = LoggerFactory.getLogger(BatchConfigModule.class); @Override protected void configure() { LOG.info("Start rocoto configuration"); Module rocotoModule = Rocoto.expandVariables(new ConfigurationModule() { @Override protected void bindConfigurations() { // default config LOG.debug("Default config"); bindProperties(Config.DEFAULT_CONFIG); LOG.debug("before config.properties"); // // For overriding default config File propertiesFile = new File(Resources.getResource("config.properties") .getFile()); if (propertiesFile.exists()) { LOG.info("config.properties was found in classpath: [" + propertiesFile.getAbsolutePath() + "]"); bindProperties(propertiesFile); } else { LOG.info("config.properties was not found in classpath"); } } }); install(rocotoModule); } } </code></pre> <p>Config.DEFAULT_CONFIG extends java.util.Properties and define default properties, each parameters in DEFAULT_CONFIG is like this => </p> <pre><code>DEFAULT_CONFIG.setProperty("testModeInt", "${testMode|false}"); </code></pre> <p>And i inject in my code property with @Named("testModeInt"). </p> <p>My problem is, if my config.properties is not present in classpath, i have an error : </p> <pre><code>Caused by: java.lang.IllegalStateException: Re-entry not allowed at com.google.inject.internal.util.$Preconditions.checkState(Preconditions.java:142) at org.nnsoft.guice.rocoto.configuration.ConfigurationModule.configure(ConfigurationModule.java:63) at com.google.inject.AbstractModule.configure(AbstractModule.java:59) at com.google.inject.spi.Elements$RecordingBinder.install(Elements.java:223) at com.google.inject.spi.Elements.getElements(Elements.java:101) at com.google.inject.spi.Elements.getElements(Elements.java:92) at com.google.inject.util.Modules$RealOverriddenModuleBuilder$1.configure(Modules.java:152) at com.google.inject.AbstractModule.configure(AbstractModule.java:59) at com.google.inject.spi.Elements$RecordingBinder.install(Elements.java:223) at com.google.inject.AbstractModule.install(AbstractModule.java:118) at net.antoine.ConfigModule.configure(ConfigModule.java:51) </code></pre> <p>Which i just don't understand, where is this problem come from, or maybe this implementation is not good, another idea ? </p>
