01 基本用法
待完善的DEMO……
1 sqlMap.properties
driver=oracle.jdbc.driver.OracleDriver url=jdbc:oracle:thin:@localhost:1521:orcl username=username password=password
2 导包，iBatis必要jar和odbc驱动，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>
<!-- 引用properties文件 -->
<properties resource="resources/SqlMap.properties" />
<settings useStatementNamespaces="true" />
<transactionManager type="JDBC">
<dataSource type="simple">
<property name="JDBC.Driver" value="${driver}" />
<property name="JDBC.ConnectionURL" value="${url}" />
<property name="JDBC.Username" value="${username}" />
<property name="JDBC.Password" value="${password}" />
</dataSource>
</transactionManager>
<sqlMap resource="dao/imp/EmpDaoSqlMap.xml" />
</sqlMapConfig>
2 实体Emp.java
package model;
import java.sql.Date;
public class Emp {
private Integer id;
private String name;
private String job;
private Integer mgr;
private Date hireDate;
private Double sal;
private Double comm;
// getters & setters
}
3 表
create table TESTEMPBYDF ( ID NUMBER(7) primary key, NAME VARCHAR2(20), JOB VARCHAR2(10), MGR NUMBER(7), HIREDATE DATE, SAL NUMBER(8,2), COMM NUMBER(8,2) ); create sequence testempbydf_seq;
4 dao接口EmpDao.java
package dao;
import java.util.List;
import model.Emp;
public interface EmpDao {
// 新增记录
void addEmp(Emp e);
// 删除记录
void deleteEmp(Integer id);
// 修改记录
void updateEmp(Emp e);
// 查询一条记录
Emp getEmp(Integer id);
// 查询全部记录
List<Emp> getAllEmp();
}
5 util类SessionFactory.java
package util;
import java.io.IOException;
import java.io.Reader;
import com.ibatis.common.resources.Resources;
import com.ibatis.sqlmap.client.SqlMapClient;
import com.ibatis.sqlmap.client.SqlMapClientBuilder;
public class SessionFactory {
private static final SqlMapClient sqlMapClient;
static {
String resource = "resources/sqlMapConfig.xml";
Reader reader = null;
try {
reader = Resources.getResourceAsReader(resource);
} catch (IOException e) {
System.out.println("sqlMapConfig.xml文件找不到");
e.printStackTrace();
}
sqlMapClient = SqlMapClientBuilder.buildSqlMapClient(reader);
}
public static SqlMapClient getSqlMapclient() {
return sqlMapClient;
}
}
6 dao实现类EmpDaoIbatisImp.java
package dao.imp;
import java.sql.SQLException;
import java.util.List;
import util.SessionFactory;
import com.ibatis.sqlmap.client.SqlMapClient;
import model.Emp;
import dao.EmpDao;
public class EmpDaoIbatisImp implements EmpDao {
private SqlMapClient client = SessionFactory.getSqlMapclient();
public void addEmp(Emp e) {
try {
client.insert("dao.imp.EmpDaoIbatisImp.add", e);
} catch (SQLException e1) {
e1.printStackTrace();
}
}
public void deleteEmp(Integer id) {
try {
client.delete("dao.imp.EmpDaoIbatisImp.delete", id);
} catch (SQLException e) {
e.printStackTrace();
}
}
public void updateEmp(Emp e) {
try {
client.update("dao.imp.EmpDaoIbatisImp.update", e);
} catch (SQLException e1) {
e1.printStackTrace();
}
}
public Emp getEmp(Integer id) {
Emp e = new Emp();
try {
e = (Emp) client.queryForObject("dao.imp.EmpDaoIbatisImp.get", id);
} catch (SQLException e1) {
e1.printStackTrace();
}
return e;
}
@SuppressWarnings("unchecked")
public List<Emp> getAllEmp() {
List<Emp> emps = null;
try {
emps = client.queryForList("dao.imp.EmpDaoIbatisImp.getAll");
} catch (SQLException e) {
e.printStackTrace();
}
return emps;
}
}
7 类-表 操作定义配置文件EmpDaoSqlMap.xml
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE sqlMap PUBLIC "-//iBATIS.com//DTD SQL Map 2.0//EN" "http://ibatis.apache.org/dtd/sql-map-2.dtd"> <sqlMap namespace="dao.imp.EmpDaoIbatisImp"> <typeAlias alias="Emp" type="model.Emp" /> <resultMap id="employee" class="model.Emp"> <result property="id" column="id" /> <result property="name" column="name" /> <result property="job" column="job" /> <result property="mgr" column="mgr" /> <result property="hireDate" column="hireDate" /> <result property="sal" column="sal" /> <result property="comm" column="comm" /> </resultMap> <insert id="add" parameterClass="Emp"> insert into testempbydf values(testempbydf_seq.nextval, #name#, #job#, #mgr#, #hireDate#, #sal#, #comm#) </insert> <delete id="delete" parameterClass="java.lang.Integer"> delete from testempbydf where id=#id# </delete> <update id="update" parameterClass="Emp"> update testempbydf set name=#name#, job=#job#, mgr=#mgr#, hireDate=#hireDate#, sal=#sal#, comm=#comm# where id=#id# </update> <select id="get" parameterClass="java.lang.Integer" resultClass="Emp"> select * from testempbydf where id=#id# </select> <select id="getAll" resultClass="Emp"> select * from testempbydf </select> </sqlMap>
