Question

我有以下代码示例捕获异常并使用IllegalStateException包装它们。

try {
    do my things...
} catch (final Exception e) {
    throw new IllegalStateException("Exception happened", e)
}

这一切正常，但在运行集成测试时，当记录IllegalStateException时，它没有显示由此引起的。

java.lang.IllegalStateException: Exception happened
    at org.apache.zookeeper.KeeperException.create(KeeperException.java:111)
    at org.apache.zookeeper.KeeperException.create(KeeperException.java:51)
    at org.apache.zookeeper.ZooKeeper.getData(ZooKeeper.java:1155)

    at <my package>.test_get_config_missing_resource(ZookeeperConfigProviderIT.java:118)

我们正在使用logback，java 8和JUnit

Logback配置（但这看起来并不是由logback输出）

<configuration>
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
  <!-- encoders are assigned the type
       ch.qos.logback.classic.encoder.PatternLayoutEncoder by default -->
  <encoder>
    <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
  </encoder>
</appender>

<root level="WARN">
    <appender-ref ref="STDOUT" />
</root>

为什么会发生这种情况？

Answer 1

原因是代码。

检查此处的grep代码以获取KeeperException create method Grep Code KeeperException

它只是抛出异常但不添加任何消息。这就是为什么你没有看到任何有用的东西。

此外，因为它只是在没有记录原始问题的情况下返回。

异常日志记录丢失引起的
