Hibernate Logging by Log4j using properties file

Log4j and Logback frameworks are used to support logging in hibernate, there are two ways to perform logging using log4j:

  1. By log4j.xml file (or)
  2. By log4j.properties file

Here, we are going to enable logging using log4j through properties file.

Create log4j.properties file

Now you need to create log4j.properties file. In this example, all the log details will be written in the D:\\logfilename.log file.( location where you want)

if you want logs present inside log folder which are created inside the src folder then write 

logs/logfilename.log

# Direct log messages to a log file

log4j.appender.file=org.apache.log4j.RollingFileAppender

#log4j.appender.file.File=D:\\javatpointhibernate.log

# Define the log folder path

log4j.appender.file.File=logs/javatpointhibernate.log


log4j.appender.file.MaxFileSize=1MB

log4j.appender.file.MaxBackupIndex=1

log4j.appender.file.layout=org.apache.log4j.PatternLayout

log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

# Direct log messages to stdout

log4j.appender.stdout=org.apache.log4j.ConsoleAppender

log4j.appender.stdout.Target=System.out

log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

# Root logger option

log4j.rootLogger=INFO, file, stdout

# Log everything. Good for troubleshooting

log4j.logger.org.hibernate=INFO

# Log all JDBC parameters

log4j.logger.org.hibernate.type=ALL

#logging.path=logs


package com.hbm;


import org.apache.log4j.Logger;


public class Testapp {


// It's a good practice to use camelCase for class names (TestApp instead of Testapp)

private static Logger logger = Logger.getLogger(Testapp.class);


public static void main(String[] args) {


// Create a SimpleLayout for logging output

// Layout layout = new SimpleLayout();

//Layout layout = new SimpleLayout();

// Use PatternLayout with a time pattern

// Layout layout = new PatternLayout("%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n");

// Layout layout = new PatternLayout("%d{yyyy-MM-dd HH:mm:ss.SSS} %-5p [%t] %c{1}.%M(%F:%L) - %m%n");

// Use a ConsoleAppender to output log messages to the console

// Appender appender = new ConsoleAppender(layout);


// Set the appender to the logger

//log.addAppender(appender);


// Log various messages with different log levels

// log.info("from info");

// log.debug("from debug");

// log.fatal("from fatal");

// log.error("from error"); // Corrected the log message

// log.warn("from warn");

// Log statements

logger.debug("Debug message");

logger.info("Info message");

logger.warn("Warning message");

logger.error("Error message");

}

}

Two Sum II - Input Array Is Sorted

 Given a 1-indexed array of integers numbers that is already sorted in non-decreasing order , find two numbers such that they add up to a specific target number. Let these two numbers be numbers[index1] and numbers[index2] where 1 <= index1 < index2 <= numbers.length. Return the indices of the two numbers, index1 and index2, added by one as an integer array [index1, index2] of length 2. The tests are generated such that there is exactly one solution. You may not use the same element twice. Your solution must use only constant extra space .   Example 1: Input: numbers = [2,7,11,15], target = 9 Output: [1,2] Explanation: The sum of 2 and 7 is 9. Therefore, index1 = 1, index2 = 2. We return [1, 2]. Example 2: Input: numbers = [2,3,4], target = 6 Output: [1,3] Explanation: The sum of 2 and 4 is 6. Therefore index1 = 1, index2 = 3. We return [1, 3]. Example 3: Input: numbers = [-1,0], target = -1 Output: [1,2] Explanation: The sum of -1 and 0 is -1. Therefore index1 = 1,...

Comparable Vs. Comparator in Java

  In Java , Comparable and Comparator both are interfaces used to sort objects. Comparable It defines  natural ordering  within a class. It is implemented  inside  the class being sorted. It uses the compareTo() method. It allows sorting  by one one . Comparable provides a  single sorting sequence . In other words, we can sort the collection on the basis of a single element such as id, name, and price. Comparable  affects the original class , i.e., the actual class is modified. Comparable is present in  java.lang  package. We can sort the list elements of Comparable type by  Collections.sort(List)  method. Only one compareTo() method can be implemented, restricting flexibility. Comparator It defines  custom sorting logic It is implemented  in a separate class  or using lambda expressions . It uses the compare() method. It allows sorting  by multiple criteria . The Comparator provides  multiple sorting...

Increasing Triplet Subsequence

 Given an integer array nums, return true if there exists a triple of indices (i, j, k) such that i < j < k and nums[i] < nums[j] < nums[k]. If no such indices exists, return false.   Example 1: Input: nums = [1,2,3,4,5] Output: true Explanation: Any triplet where i < j < k is valid. Example 2: Input: nums = [5,4,3,2,1] Output: false Explanation: No triplet exists. Example 3: Input: nums = [2,1,5,0,4,6] Output: true Explanation: The triplet (3, 4, 5) is valid because nums[3] == 0 < nums[4] == 4 < nums[5] == 6. Brute Force : Failed for some testcase class Solution {     public boolean increasingTriplet ( int [] nums ) {         int n = nums . length ;         int i = 0 ;         int j =i+ 1 ;         int k =j+ 1 ;         while (i <n && j<n && k<n)         {         if (nums...
