该篇主要Service层代码以及针对Service层功能的Junit测试代码
在src下创建包com.zyg.ssi.service，在该包下创建接口StudentService，其代码如下：

package com.zyg.ssi.service;

import java.util.List;
import com.zyg.ssi.bean.Student;

public interface StudentService {

	/**
	 * 保存学生信息
	 * @param student
	 */
	public abstract void save(Student student);

	/**
	 * 根据学号删除学生信息
	 * @param studentId
	 */
	public abstract void delete(Integer studentId);

	/**
	 * 更新学生信息
	 * @param student
	 */
	public abstract void update(Student student);

	/**
	 * 根据学号获取学生信息
	 * @param studentId
	 */
	public abstract Student getStudent(Integer studentId);

	/**
	 * 获取全部学生信息
	 * @param studentId
	 */
	public abstract List<Student> getStudents();
	
	/**
	 * 通过学生姓名获取学生信息
	 * @param studentId
	 */
	public abstract List<Student> getStudentsByName(String name);
}

在src下创建包com.zyg.ssi.service.impl，在该包下创建实现StudentService接口的类StudentServiceImpl，其代码如下：
package com.zyg.ssi.service.impl;
import java.util.List;

import javax.annotation.Resource;

import com.zyg.ssi.bean.Student;
import com.zyg.ssi.dao.StudentDao;
import com.zyg.ssi.service.StudentService;

public class StudentServiceImpl implements StudentService {
	@Resource
	private StudentDao studentDao;
	
	/* (non-Javadoc)
	 * @see com.zyg.ssj.service.impl.StudentService#save(com.zyg.ssj.bean.Student)
	 */
	public void save(Student student){
		studentDao.addStudent(student);
	}
	
	/* (non-Javadoc)
	 * @see com.zyg.ssj.service.impl.StudentService#delete(java.lang.Integer)
	 */
	public void delete(Integer studentId){
		studentDao.delStudentById(studentId);
	}
	
	/* (non-Javadoc)
	 * @see com.zyg.ssj.service.impl.StudentService#update(com.zyg.ssj.bean.Student)
	 */
	public void update(Student student){
		studentDao.updateStudentById(student);
	}
	
	/* (non-Javadoc)
	 * @see com.zyg.ssj.service.impl.StudentService#getStudent(java.lang.Integer)
	 */
	public Student getStudent(Integer studentId){
		return studentDao.queryStudentById(studentId);
	}
	
	/* (non-Javadoc)
	 * @see com.zyg.ssj.service.impl.StudentService#getStudents()
	 */
	public List<Student> getStudents(){
		return studentDao.queryAllStudents();
	}
	
	/* (non-Javadoc)
	 * @see com.zyg.ssj.service.impl.StudentService#getStudentDao()
	 */
	public StudentDao getStudentDao() {
		return studentDao;
	}

	/* (non-Javadoc)
	 * @see com.zyg.ssj.service.impl.StudentService#setStudentDao(com.zyg.ssj.dao.StudentDao)
	 */
	public void setStudentDao(StudentDao studentDao) {
		this.studentDao = studentDao;
	} 
	
	public List<Student> getStudentsByName(String name) {
		// TODO Auto-generated method stub
		return studentDao.queryStudentByName(name);
	}
}


完成Service层代码后，需要编写Junit单元测试代码对Service层功能进行测试。

在项目中加入Junit4支持：
选中项目点击右键选择BuildPath->Configure Build path->Libraries->Add Library->Junit->Junit4。
在src目录下创建包com.zyg.ssi.junit.test，在该包下创建Junit单元测试类StudentServiceTest，其代码如下：
package com.zyg.ssi.junit.test;

import org.junit.BeforeClass;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.zyg.ssi.bean.Student;
import com.zyg.ssi.service.StudentService;

public class StudentServiceTest {
	
	private static StudentService studentService;
	
	@BeforeClass
	public static void setUpBeforeClass() throws Exception {
		try {
			ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml");
			System.out.println(ctx);
			studentService = (StudentService)ctx.getBean("studentService");
		} catch (RuntimeException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}
	
	@Test
	public void addStudent(){
		for(int i=0;i<10;i++){
			Student stu = new Student();
			stu.setStuName("欢迎访问长弓博客"+(i+1));
		}
		
		/*Student stu = new Student();
		stu.setStuName("长弓1");
		studentService.save(stu);*/
		System.out.println("添加学生后所有学生信息：");
		queryAllStudents();
	}
	
	@Test
	public void updateStudent(){
		Student stu = studentService.getStudent(11);
		System.out.println("更新前学生姓名："+stu.getStuName());
		stu.setStuName("我是长弓");
		studentService.update(stu);
		stu = studentService.getStudent(11);
		System.out.println("更新后学生姓名："+stu.getStuName());
	}
	
	
	@Test
	public void queryAllStudents(){
		for(Student student:studentService.getStudents()){
			System.out.println(student);
		}
	}
	
	@Test
	public void queryStudentByName(){
		for(Student student:studentService.getStudentsByName("博客")){
			System.out.println(student);
		}
	}
	
	@Test
	public void queryStudentById(){
		Student stu = studentService.getStudent(1);
		System.out.println(stu);
	}
	
	@Test
	public void deleteStudentById(){
		System.out.println("--------------删除前所有学生信息：");
		queryAllStudents();
		studentService.delete(10);
		System.out.println("--------------删除后所有学生信息：");
		queryAllStudents();
	}
}


运行StudentServiceTest保证CRUD操作能够正常运行，Spring2.5整合Ibaits成功。
至此，完成了Spring2.5+Struts2+Ibaits整合的第1步，即Spring2.5+Ibaits的整合，对于第2步中在Spring2.5+Ibaits的基础上再整合Struts2的操作，跟Spring2.5+Struts2+Jpa系列文章中在Spring2.5+Jpa的基础上再整合Struts2的操作完全相同，故不再赘述。下面提供在Spring2.5+Jpa的基础上再整合Struts2操作的链接地址，供有兴趣的读者参考：
