Logback ClassCircularityError

标签： java eclipse tomcat logback slf4j

我从Windows更改为Ubuntu 17.04，现在通过Eclipse Neon.3发行版（4.6.3）在Tomcat 8.0.36上启动webapp时出现错误。

java.lang.ClassCircularityError: ch/qos/logback/core/spi/FilterReply

该项目是通过M2E构建的，其中包含AspectJ。

使用以下SLF4J依赖项：

    <dependency>
        <groupId>ch.qos.logback</groupId>
        <artifactId>logback-classic</artifactId>
        <version>1.1.7</version>
    </dependency>

    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>jul-to-slf4j</artifactId>
        <version>1.7.21</version>
    </dependency>

    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>jcl-over-slf4j</artifactId>
        <version>1.7.21</version>
    </dependency>

它在Windows Eclipse下工作，具有几乎相同的设置和安装。 它也适用于我mvn clean package（默认的ubuntu maven安装不是eclipse）并将其手动部署到Ubuntu的默认Tomcat安装。 我已经将我的eclipse版本更改为Oxygen并遇到了同样的问题。 我试图改变依赖项的版本 - 结果相同。

我已将代码扩展到试图获取JDNI对象的“ServletContextListener”：

import java.net.URL;
import java.util.logging.Level;
import java.util.logging.LogRecord;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;
import org.slf4j.LoggerFactory;
import org.slf4j.bridge.SLF4JBridgeHandler;
import ch.qos.logback.classic.LoggerContext;
import ch.qos.logback.classic.joran.JoranConfigurator;
import ch.qos.logback.classic.jul.LevelChangePropagator;
import ch.qos.logback.core.util.StatusPrinter;

// ....

@Override
public void contextInitialized(final ServletContextEvent sce) {
    new LogRecord(Level.FINEST, "Ensure class is loaded!");

    // Prepare logging context
    final LoggerContext context = (LoggerContext) LoggerFactory.getILoggerFactory();
    context.reset();

    // setup JUL to SLF4J log bridging
    SLF4JBridgeHandler.removeHandlersForRootLogger();
    SLF4JBridgeHandler.install();
    final LevelChangePropagator levelChangePropagator = new LevelChangePropagator();
    levelChangePropagator.setResetJUL(true);
    levelChangePropagator.setContext(context);
    levelChangePropagator.start();
    context.addListener(levelChangePropagator);

    // Load context values
    String contextPath = sce.getServletContext().getContextPath().replaceAll("[^0-9a-zA-Z-_]", "");
    if(contextPath.length() == 0){
        contextPath = "ROOT";
    }
    context.putProperty("appName", contextPath);
    final Boolean isProductiveVal = (Boolean) getJNDI(IS_PRODUCTIVE_JNDI);

// .....

private static Object getJNDI(final String jndiPath) {
    try {
        final Context initialContext = new InitialContext(); // << This line crashes
        return initialContext.lookup(jndiPath);
    } catch (Exception e) {
        throw new RuntimeException(e);
    }
}

我不知道我可以尝试修复它。 而且我还没有完全理解这个问题。 Tomcat尝试加载一个自我引用的类？！

有人知道我能检查什么吗？

完整堆栈的Tomcat启动。

1 个答案:

答案 0 :(得分：0)

我改为我在windows中使用的Tomcat8安装。 它终于奏效了（我不知道前任主管在那里做了什么）。

我能立即看到的唯一区别是它在Tomcat端也使用了Log4j。也许这就是差异。对不起，如果其他人也有这个问题，没有解决方案。
