测试前期准备
第一步:创建easybuy数据库,设置utf-8格式
第二步:创建表test_tb
CREATE TABLE `test_tb` ( `id` int(11) NOT NULL AUTO_INCREMENT, `name` varchar(255) DEFAULT NULL, `birthday` datetime DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8;
第三步:创建JavaBean
package cn.easybuy.core.bean; import java.util.Date; public class TestTb { private Integer id; private String name; private Date birthday; public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public Date getBirthday() { return birthday; } public void setBirthday(Date birthday) { this.birthday = birthday; } }
第四步:创建mapper文件
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <mapper namespace="cn.easybuy.core.dao.TestTbDao"> <!-- 添加测试数据 --> <insert id="addTestTb" parameterType="TestTb"> insert into test_tb (name,birthday) values (#{name},#{birthday}) </insert> </mapper>
第五步:创建Dao接口
package cn.easybuy.core.dao; import cn.easybuy.core.bean.TestTb; public interface TestTbDao { public void addTestTb(TestTb testTb); }
这里我们只需要创建一个借口就可以,不需要实现类
第六步:创建Service接口和实现类
package cn.easybuy.core.service; import cn.easybuy.core.bean.TestTb; public interface TestTbService { public void addTestTb(TestTb testTb); }
package cn.easybuy.core.service; import javax.annotation.Resource; import org.springframework.stereotype.Service; import org.springframework.transaction.annotation.Transactional; import cn.easybuy.core.bean.TestTb; import cn.easybuy.core.dao.TestTbDao; @Service @Transactional public class TestTbServiceImpl implements TestTbService{ @Resource private TestTbDao testTbDao; public void addTestTb(TestTb testTb) { testTbDao.addTestTb(testTb); } }
Junit环境搭建(Spring提供的)
第一步:创建SpringJunitTest类
package cn.easybuy.common.junit; import org.junit.runner.RunWith; import org.springframework.test.context.ContextConfiguration; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; /** * 公用类 * @author Evan * */ @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations = "classpath:application-context.xml") public class SpringJunitTest { }
这个是测试类的基类,上面加入了两个注解标签用于指定上下文和运行测试类,以后子类只需要继承即可,不需要再加上注解
第二步:Junit单元测试环境搭建,创建测试类
package cn.easybuy; import java.util.Date; import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.test.context.ContextConfiguration; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; import cn.easybuy.common.junit.SpringJunitTest; import cn.easybuy.core.bean.TestTb; import cn.easybuy.core.service.TestTbService; public class TestTestTb extends SpringJunitTest{ @Autowired private TestTbService testTbService; @Test public void testAdd() throws Exception { TestTb testTb = new TestTb(); testTb.setName("测试1"); testTb.setBirthday(new Date()); testTbService.addTestTb(testTb); } }
