iBatis最棒的特點就是它的簡潔,這也是唯一令它在任何數據庫程序中更容易使用的原因.iBatis使得通過Java或者任何其它的Microsoft的程序來使用數據庫變得非常簡單.本章我們將會通過一個例子向你介紹如何向數據庫插入一行數據.我們使用MySQL作爲本例的數據庫,和我們上一章中使用的是一樣的.這是"Contact"表和我們上一章使用過的兩個文件:"Contact.java"和"SqlMapConfig.xml"
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>
我們使用<insert>標籤來映射SQL語句,在該標籤中我們定義了一個"id",它將在IbatisInsertion.java文件中用來執行數據庫插入,查詢操作.
<selectKey resultClass="int" keyProperty="id">
select last_insert_id() as id
</selectKey>
上面的代碼指出了表中被插入數據的下一行.
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>
IbatisInsertion.java的代碼如下 :
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","[email protected]");
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("===============================================");
}
}
如何執行本例 :
1.創建Contact.java並將其編譯
2.創建Contact.xml和SqlMapConfig.xml
3.創建IbatisInsertion.java
4.執行IbatisInsertion類文件,結果將在你的命令提示符上輸出如下 :
"Record Inserted Successfully"
輸出 :
