Answer 1

最新的公共配置文件位于以下位置：

如果您阅读该文件中的注释/代码，您将看到如何处理文件位置。

为了正确使用该库，您将需要esapi.properties和validation.properties。

/**
 * The reference {@code SecurityConfiguration} manages all the settings used by the ESAPI in a single place. In this reference
 * implementation, resources can be put in several locations, which are searched in the following order:
 * <p>
 * 1) Inside a directory set with a call to SecurityConfiguration.setResourceDirectory( "C:\temp\resources" ).
 * <p>
 * 2) Inside the System.getProperty( "org.owasp.esapi.resources" ) directory.
 * You can set this on the java command line as follows (for example):
 * <pre>
 *              java -Dorg.owasp.esapi.resources="C:\temp\resources"
 * </pre>
 * You may have to add this to the start-up script that starts your web server. For example, for Tomcat,
 * in the "catalina" script that starts Tomcat, you can set the JAVA_OPTS variable to the {@code -D} string above.
 * <p>
 * 3) Inside the {@code System.getProperty( "user.home" ) + "/.esapi"} directory (supported for backward compatibility) or
 * inside the {@code System.getProperty( "user.home" ) + "/esapi"} directory.
 * <p>
 * 4) The first ".esapi" or "esapi" directory on the classpath. (The former for backward compatibility.)
 * <p>
 * Once the Configuration is initialized with a resource directory, you can edit it to set things like master
 * keys and passwords, logging locations, error thresholds, and allowed file extensions.
 * <p>
 * WARNING: Do not forget to update ESAPI.properties to change the master key and other security critical settings.
