iBatis-Inserting data into database
The greatest feature of iBatis is
it’s simplicity, and that is the only reason of being it easier to use in any
database application. iBatis makes it really simple to use a database with Java
or any other Microsoft applications. In this section we will introduce you with an example
which is inserting a row into database. And for this we are using MySQL as a
database it is the same one we have used in our previous example. The
table name is "Contact" and we have used two files "Contact.java" and
"SqlMapConfig.xml" as we did in previous example.
Contact.java
public class Contact {
private String firstName;
private String lastName;
private String email;
private int id;
public Contact() {}
public Contact(
String firstName,
String lastName,
String email) {
this.firstName = firstName;
this.lastName = lastName;
this.email = email;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
}

SqlMapConfig.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE sqlMapConfig
PUBLIC "-//ibatis.apache.org//DTD SQL Map Config 2.0//EN"
"http://ibatis.apache.org/dtd/sql-map-config-2.dtd">
<sqlMapConfig>
<settings useStatementNamespaces="true"/>
<transactionManager type="JDBC">
<dataSource type="SIMPLE">
<property name="JDBC.Driver" value="com.mysql.jdbc.Driver"/>
<property name="JDBC.ConnectionURL"
value="jdbc:mysql://192.168.10.112:3306/vin"/>
<property name="JDBC.Username" value="root"/>
<property name="JDBC.Password" value="root"/>
</dataSource>
</transactionManager>
<sqlMap resource="Contact.xml"/>
</sqlMapConfig> |
For SQL mapping statement we have used <insert>
tag. Inside this tag definition we have defined an "id" which
will be used in IbatisInsertion.java file for executing insert query on
database.
<selectKey resultClass="int"
keyProperty="id">
select
last_insert_id() as id
</selectKey> |
Above lines of code points to next row of the table where
the next value is to be inserted.
Contact.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE sqlMap
PUBLIC "-//ibatis.apache.org//DTD SQL Map 2.0//EN"
"http://ibatis.apache.org/dtd/sql-map-2.dtd">
<sqlMap namespace="Contact">
<!--- Inserting data in table -->
<insert id="insert" parameterClass="Contact">
insert into contact (firstName,lastName,email)
values (#firstName#, #lastName#, #email#)
<selectKey resultClass="int" keyProperty="id">
select last_insert_id() as id
</selectKey>
</insert>
<!--- Showing all data of table -->
<select id="getAll" resultClass="Contact">
select * from contact
</select>
</sqlMap> |
Full source code of IbatisInsertion.java is as
follows:
IbatisInsertion.java
import com.ibatis.common.resources.Resources;
import com.ibatis.sqlmap.client.SqlMapClient;
import com.ibatis.sqlmap.client.SqlMapClientBuilder;
import java.io.*;
import java.sql.SQLException;
import java.util.*;
public class IbatisInsertion{
public static void main(String[] args) throws IOException,SQLException{
Reader reader = Resources.getResourceAsReader("SqlMapConfig.xml");
SqlMapClient sqlMap = SqlMapClientBuilder.buildSqlMapClient(reader);
//Inserting one record in contacts
System.out.println(
"*-------------- Inserting information in Contact Table -----------*");
Contact contact=new Contact("Amit","Kumar","amit@roseindia.net");
sqlMap.insert("Contact.insert",contact);
System.out.println("|Record Inserted Successfully ");
System.out.println("All Contacts");
List<Contact> contacts = (List<Contact>)
sqlMap.queryForList("Contact.getAll",null);
Contact contactall = new Contact();
for (Contact c : contacts) {
System.out.print(" " + c.getId());
System.out.print(" " + c.getFirstName());
System.out.print(" " + c.getLastName());
System.out.print(" " + c.getEmail());
contact = c;
System.out.println("");
}
System.out.println("===============================================");
}
}

To run this example :
- Create and save Contact.java and compile it.
- Create and save Contact.xml and SqlMapConfig.xml
- Create and save IbatisInsertion.java and
- execute IbatisInsertion class file and
output on your command prompt will be flashed as
"Record Inserted Successfully"
