Port 8080 already in use

I was facing this problem. Port 8080 was already in use.


I was using Spring Tool Suite ( Version: 3.8.4.RELEASE).  port 8080 was not free.  to release this port  in windows operation system.

to view all the port command are 

1.   netstatus -ano 

to find the process id attached with port 8080

2.   netstat  -ano  |  findstr  8080

kill the process and release the port for further use.

3.   taskkill  /F  /PID  4500 ( provide your process id)

JPA mappedBy and JoinColumn

Image
In database we have a foreign key.  In simple foreign key establish the relationship between two database tables. Primary key of one table is placed into another table.  That key is called  foreign key. Here can have a book table and author table . Every author is linked with those books which are written by him.  So inside the book there is author name. that reflect the relation.  In relationship database model. Author is identified by his unique identification, This is the primary key of author table.  Book table will contain the identification of author. Book table have author id and this foreign key is not unique in book table. One single author can write multiple books, @JoinColumn specifies the foreign key column is the Book table that links to the Author entity. In this case, it's author_id. A n example of how to use @JoinColumn annotation with @ManyToOne and @OneToMany relationships in JPA. Consider two entities Author and Book , where an author...

Aggregate function with spring data

Image
I was working on a small project. Requirement was different in term of object mapping. There is simple way to map  java object with database table. Aggregate function in query is not mapped with entity class. We don't have direct mapping attribute in JPA annotation to map aggregate function with entity class. Spring data support this using interface. In ORM query we use aggregate function e.g. count , sum etc. the output of these aggregate function cannot directly map with the Entity class. To collect the outcome of aggregate methods. We need to map using interface in java and provide the Interface class with mapping method.      public List<ITeacherReport> getTeacherReport(String teacherName); Our requirement is to count solved question per month by teacher from answer table. We have below environment configuration. Thymeleaf (for view,  this is template engine) JDK 1.8 Maven Springboot framework  MySql  for database operation Open the start....

Let's try to build simple java application with the help of Spring Tool Suites IDE, Spring-Data connecting and MySql's relation database. You are free to choose any IDE (STS, Eclipse, Intellij etc).  We are building simple application which is storing User information into MySQL Database table. Our Requirements are simple IDE (any IDE, STS, Eclipse or Intellij) JDK 1.8 later  Maven 3.2 Create a Maven project using spring initializr   Open the Spring Initializr ( https://start.spring.io/  ).  This is the best way to start the project. Type the https://start.spring.io on url browser  The Initializr provides quick solution to place dependency and create project structure. Our requirement is JPA and MySql dependencies. below image shows the Initializr with required dependency selection: Following  pom.xml  file  will be generated having   spring-boot-starter-data  and   mysql-con...
