This is an example program for Spring Batch

This is the test of spring batch which read from db table and write to db table (mysql)

By default spring batch DataSource uses the HSQL. Here I am using JPA and set the database platform (like MySQL) to point to a specific database (other than the default HSQL).

Used Following

• spring-batch-core 3.0.1.RELEASE
• spring-boot-starter-batch 1.1.5.RELEASE
• spring-boot-starter-data-jpa 1.1.5.RELEASE
• mysql
• gradle

I am also using gradle wrapper (http://www.gradle.org/docs/current/userguide/gradle_wrapper.html). The wrapper is something you should check into version control. By distributing the wrapper with your project, anyone can work with it without needing to install Gradle beforehand. Add following to build.gradle

• task wrapper(type: Wrapper) { gradleVersion = '1.11' }

Command to create gradlew:-

• gradle wrapper

I am also using Spring Boot (http://projects.spring.io/spring-boot/). This helps to create a stand-along spring app - just run the app. To make the app spring-boot add the following line to build.gradle

• apply plugin: 'spring-boot'

• following Dependencies:-

** compile 'org.springframework.boot:spring-boot-starter-batch:1.1.5.RELEASE'

** compile 'org.springframework.boot:spring-boot-starter-data-jpa:1.1.5.RELEASE'

Command to spring boot

• gradlew bootRun

• gradlew run

DDL:-

CREATE TABLE person ( id bigint(20) NOT NULL AUTO_INCREMENT, first_name varchar(45) DEFAULT NULL, last_name varchar(45) DEFAULT NULL, PRIMARY KEY (id) ) ENGINE=InnoDB AUTO_INCREMENT=7 DEFAULT CHARSET=utf8;

CREATE TABLE account ( accountId bigint(20) NOT NULL, firstName varchar(45) DEFAULT NULL, lastName varchar(45) DEFAULT NULL, PRIMARY KEY (accountId) ) ENGINE=InnoDB DEFAULT CHARSET=utf8;

INSERT INTO account (accountId, firstName, lastName) VALUES (1,'first name','last name');
