Question

我的程序编译没有任何错误。但是执行大文件时，出现以下异常：

    [ERROR] Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.2.1:java (default-cli) on project rdf4j-getting-started: 
    An exception occured while executing the Java class. null: InvocationTargetException: The parser has encountered
 more than "100,000" entity expansions in this document; this is the limit imposed by the application. -> [Help 1]

我正在使用以下命令：

mvn -Djdk.xml.totalEntitySizeLimit=0 -DentityExpansionLimit=0  exec:java

我的pom具有所有依赖性：

我使用以下Java版本：

java version "1.8.0_192"
Java(TM) SE Runtime Environment (build 1.8.0_192-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.192-b12, mixed mode)

请帮忙

我的命令是正确的。我通过添加到pom文件解决了这个问题：

<dependency>
        <groupId>ch.qos.logback</groupId>
        <artifactId>logback-classic</artifactId>
        <version>1.0.13</version>
    </dependency>

为什么我无法在Java中读取大数据文件？
