test数据库的user表在运行前状态：
通过 junit进行插入3条记录：
import java.util.List;
import Controller.Application;
import mapper.UserMapper;
import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import pojo.User;
@SpringBootTest(classes = {Application.class})
public class UserMapperTest extends BaseTest{
@Autowired
private UserMapper userMapper;
@Test
public void testInsert() {
try {
userMapper.insert(new User("man1", "男", 26));
userMapper.insert(new User("man2", "男", 23));
userMapper.insert(new User("man2", "男", 27));
} catch (Exception e) {
e.printStackTrace();
}
}
@Test
public void testUpdate() {
try {
User user = new User("测试0000", "男", 23);
user.setId(11l);
userMapper.update(user);
} catch (Exception e) {
e.printStackTrace();
}
}
@Test
public void testQuery() {
try {
List users=userMapper.findList();
for(User u:users){
System.out.println("ID:"+u.getId()+" Name:"+u.getUserName()+" Sex:"+u.getUserSex()+" Age:"+u.getUserAge());
}
} catch (Exception e) {
e.printStackTrace();
}
}
@Test
public void testDelete(){
try {
userMapper.delete(11l);
testQuery();
} catch (Exception e) {
e.printStackTrace();
}
}
}
测试update
测试 query all
测试delete
最后，启动spring boot
测试Controller
测试成功！
