iBATIS与Spring的集成

构造JavaBean如下(get,set方法省略)：

public class Student {
	private Integer stu_id;

	private String stu_name;

	private Integer stu_age;

	private float stu_score;

	private Date stu_birth;
}

 在JavaBean包里新建一个Student.xml，内容如下：

<?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="student">

	<typeAlias alias="Student" type="com.mengya.bean.Student" />

	<insert id="save" parameterClass="Student">
		insert into student
		values(#stu_id#,#stu_name#,#stu_age#,#stu_score#,#stu_birth#)
	</insert>

	<delete id="delStuByID" parameterClass="int">
		delete from student where stu_id = #stu_id#
	</delete>

	<update id="update" parameterClass="Student">
		update student set
		stu_name=#stu_name#,stu_age=#stu_age#,stu_score=#stu_score#,stu_birth=#stu_birth#
		where stu_id=#stu_id#
	</update>

	<select id="queryAll" resultClass="Student">
		select * from student
	</select>

	<select id="queryById" resultClass="Student" parameterClass="int">
		select * from student where stu_id = #stu_id#
	</select>

</sqlMap>

 构造dao接口如下：

public interface StudentDao {
	public void save(Student stu);

	public void delete(int stu_id);

	public void update(Student stu);

	public Student queryByPK(int stu_id);

	public List<Student> queryAll();
}

 对dao的实现：继承Spring提供的org.springframework.orm.ibatis.support.SqlMapClientDaoSupport

public class StudentDaoImple extends SqlMapClientDaoSupport implements
		StudentDao {

	public void delete(int stu_id) {
		getSqlMapClientTemplate().delete("delStuByID", stu_id);
	}

	public List<Student> queryAll() {
		return getSqlMapClientTemplate().queryForList("queryAll");
	}

	public Student queryByPK(int stu_id) {
		return (Student) getSqlMapClientTemplate().queryForObject("queryById",
				stu_id);
	}

	public void save(Student stu) {
		getSqlMapClientTemplate().insert("save", stu);
	}

	public void update(Student stu) {
		getSqlMapClientTemplate().update("update", stu);
	}

}

 构造service接口：

public interface StudentService {
	public void save(Student stu);

	public void delete(int stu_id);

	public void update(Student stu);

	public Student queryByPK(int stu_id);

	public List<Student> queryAll();
}

 对service的实现：

public class StudentServiceImple implements StudentService {

	private StudentDao studao;

	public void setStudao(StudentDao studao) {
		this.studao = studao;
	}

	public void delete(int stu_id) {
		this.studao.delete(stu_id);
	}

	public List<Student> queryAll() {
		return studao.queryAll();
	}

	public Student queryByPK(int stu_id) {
		return studao.queryByPK(stu_id);
	}

	public void save(Student stu) {
		studao.save(stu);
	}

	public void update(Student stu) {
		studao.update(stu);
	}

}

 iBATIS的sqlMapConfig.xml配置如下：

<!DOCTYPE sqlMapConfig PUBLIC "-//ibatis.apache.org//DTD SQL Map Config 2.0//EN"
	"http://ibatis.apache.org/dtd/sql-map-config-2.dtd">
<sqlMapConfig>
	<sqlMap resource="com/mengya/bean/Student.xml" />
</sqlMapConfig>

 Spring的applicationContext.xml配置如下：

<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:context="http://www.springframework.org/schema/context"

public class StudentAction extends ActionSupport {
	private StudentService stuMght;

	private Student stu;

	private List<Student> stuList;

	public StudentService getStuMght() {
		return stuMght;

	public String list() {
		this.stuList = stuMght.queryAll();
		return "list";
	}

	public Student getStu() {
		return stu;
	}

	public void setStu(Student stu) {
		this.stu = stu;
	}

	public List<Student> getStuList() {
		return stuList;
	}

	public void setStuList(List<Student> stuList) {
		this.stuList = stuList;
	}

}

struts.xml的配置如下：

<struts>
	<constant name="struts.i18n.encoding" value="gbk" />
	<constant name="struts.objectFactory" value="spring" />
	<package name="mengya" extends="struts-default">
		<action name="student_*" class="studentAction" method="{1}">
			<result name="list">/list.jsp</result>
		</action>
	</package>
</struts>

 web.xml配置如下：

<filter>
		<filter-name>struts2</filter-name>
