Question

我正在使用带有Logback的SLF4J来记录错误消息。其中一个观察结果是，一些根本原因需要toString()而不是getMessage()。例如，如果异常被包装在另一个异常中，SLF4J会打印“＃”;根本原因而不是toString()中间接引用的异常消息。 Java util库日志很好。但是，我必须使用SLF4J-Logback。有没有什么方法可以覆盖SLF4J和logback的默认行为。

class TestException extends Exception
        {
            private String exceptionCode;
            private String exceptionMessage;

            @Override
            public String toString()
            {
                return "TestException [exceptionCode=" + exceptionCode + ", exceptionMessage=" + exceptionMessage + "]";
            }
        }

        try
        {
            TestException testException = new TestException();
            testException.exceptionCode = "Test exception code";
            testException.exceptionMessage = "Test exception message";
            throw new IOException("Io message", testException);
        }
        catch (Exception e)
        {
            logger.error("Error message ", e);
            java.util.logging.Logger.getAnonymousLogger().log(java.util.logging.Level.SEVERE, "Error message", e);
        }

输出呈现：
