java - ESAPI - 获取具有禁止依赖项的 NoClassDefFoundError (LoggerFactory)

Question

我正在使用 espai ESAPI 对字符串值进行编码以解决跨站点脚本问题，如下所示(代码片段)。

String encodedString = ESAPI.encoder().encodeForHTML(value);

异常跟踪

org.owasp.esapi.errors.ConfigurationException: java.lang.reflect.InvocationTargetException Encoder class (org.owasp.esapi.reference.DefaultEncoder) CTOR threw exception.

Maven 存储库 pom.xml

<dependency>
    <groupId>org.owasp.esapi</groupId>
    <artifactId>esapi</artifactId>

如果我不排除 log4j 那么它会抛出依赖收敛错误，因为 log4j 是在 maven banned 依赖中声明的，如下所示

    <execution>
        <id>enforce</id>
        <configuration>
            <rules>

                    <version>3.0</version>
                </requireMavenVersion>
                <DependencyConvergence />
                <bannedDependencies>

                        <!-- This should not exist as it will force SLF4J calls to be

                        <!-- As recommended from the slf4j guide, exclude commons-logging -->

                    </excludes>

        <goals>

        </goals>
    </execution>
</executions>

在这方面的帮助将不胜感激。如果您需要更多详细信息，请告诉我。提前致谢!

我升级到最新版本 2.2.1.1 并且我需要在 ESAPI.properties 中添加两个额外的属性(除了 @Carlo 指出的那个) :

ESAPI.Logger=org.owasp.esapi.logging.slf4j.Slf4JLogFactory
Logger.UserInfo=false
Logger.ClientInfo=false
