Simple project using Oracle database with Spring, and Maven

Installation

• You will need to have setup the Oracle database and populate the data using the script provided (see below)
• You will need to copy the Oracle's jar file and install it to manually (see below)
• Edit your hibernate.cfg.xml file to your Oracle's setup (username, password, host, port, etc)

Install Oracle's jar manually using the following command

mvn install:install-file -Dfile=./ojdbc.jar -DgroupId=com.oracle -DartifactId=ojdbc6 -Dversion=11.2.0 -Dpackaging=jar

The reason we need to do this because we have the following section in pom.xml file

<dependency>
  <groupId>com.oracle</groupId>
  <artifactId>ojdbc6</artifactId>
  <version>11.2.0</version>
</dependency>

You will also need to create following table in Oracle using the following DDL.

CREATE TABLE DBUSER ( 
  USER_ID      NUMBER(12)    NOT NULL, 
  USER_NAME    VARCHAR2(20)  NOT NULL, 
  CREATED_BY   VARCHAR2(20)  NOT NULL, 
  CREATED_DATE DATE          NOT NULL, 
  PRIMARY KEY (USER_ID) 
);

CREATE TABLE DEPARTMENT ( 
  DEPT_ID     NUMBER(12)   NOT NULL, 
  DEPT_NAME   VARCHAR2(20) NOT NULL, 
  PRIMARY KEY (DEPT_ID) 
);

CREATE TABLE EMPLOYEE (
    EMP_ID     NUMBER(12)  NOT NULL,
    FIRST_NAME VARCHAR2(50) NOT NULL,
    LAST_NAME  VARCHAR2(50) NOT NULL,
    BIRTH_DATE DATE            NULL,
    CELL_PHONE VARCHAR2(15)     NULL,
    DEPT_ID    NUMBER(12)      NULL,
    PRIMARY KEY(EMP_ID)
);

ALTER TABLE EMPLOYEE ADD (
  CONSTRAINT EMP_DEPT_FK 
  FOREIGN KEY (EMP_ID) 
  REFERENCES DEPARTMENT(DEPT_ID));

CREATE SEQUENCE EMP_SEQ
START WITH 0
INCREMENT BY 1
MINVALUE 0
NOCACHE 
NOCYCLE 
NOORDER;

Edit your hibernate configuration file to your environment

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
  <session-factory>
    <property name="hibernate.connection.driver_class">oracle.jdbc.driver.OracleDriver</property>
    <property name="hibernate.connection.url">jdbc:oracle:thin:@<YOUR_SERVER_IP>:1521:<YOUR_SID></property>
    <property name="hibernate.connection.username">YOUR_DB_LOGIN</property>
    <property name="hibernate.connection.password">YOUR_DB_PASSWORD</property>
    <property name="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</property>
    <property name="hibernate.default_schema">YOUR_SCHEMA_NAME</property>
    <property name="show_sql">true</property>
    <mapping resource="com/demo/example/dbuser.hbm.xml"></mapping>
    <mapping resource="com/demo/example/department.hbm.xml"></mapping>
    <mapping resource="com/demo/example/employee.hbm.xml"></mapping>
  </session-factory>
</hibernate-configuration>

Once this is done you can then

Then you can run the following command

$mvn clean eclipse:eclipse install

If you want so use it from Eclipse then just use File->Import
