Spring2.5+Struts2+Ibatis整合之五

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 {@Resourceprivate 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 stubreturn 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;@BeforeClasspublic 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 blocke.printStackTrace();}}@Testpublic 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();}@Testpublic 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());}@Testpublic void queryAllStudents(){for(Student student:studentService.getStudents()){System.out.println(student);}}@Testpublic void queryStudentByName(){for(Student student:studentService.getStudentsByName("博客")){System.out.println(student);}}@Testpublic void queryStudentById(){Student stu = studentService.getStudent(1);System.out.println(stu);}@Testpublic 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：
