问题遇到的现象和发生背景
在编写一个面向切面的简单程序时尝试使用Mybatis, 但是卡在org.apache.ibatis.binding.BindingException: Invalid bound statement (not found): 错误中无法解决.
问题相关代码，请勿粘贴截图
Mapper类:
@Mapper
@Repository
public interface UserLogMapper {
int insertLogin(@Param("userLog") UserLog userLog); // 登入记录
}
Service类:
@Service
public class UserLogService {
@Autowired
UserLogMapper userLogMapper;
/**
* 插入登入记录
* @param user 用户体
* @return 插入反馈
*/
public int insertLogin(User user){
Timestamp time = new Timestamp(System.currentTimeMillis());
UserLog userLog = new UserLog(user.getId(), user.getUsername(), time, true);
return userLogMapper.insertLogin(userLog);
}
}
<!-UserLogMapper.xml-!>

/**

*/
@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest
public class LogAOPTest {
// 直接用Mapper避免多层调用导致StackOverflow
@Autowired
private UserLogMapper userLogMapper;
/**
* 测试登入记录
*/
@Test
public void insertLoginTest(){
User user = new User(1,"usr50035", "123456");
Timestamp time = new Timestamp(System.currentTimeMillis());
UserLog userLog = new UserLog(user.getId(), user.getUsername(), time, true);
int status = userLogMapper.insertLogin(userLog);
System.out.println(status);
}
}
AOP类:
@Aspect
@Component
public class LogAOP {
@Autowired
private UserLogService userLogService;
// 登入切点
@Around("execution(* xmu.mw.aoptest.Service.UserLogService.insertLogin(*))")
public void loginLog(ProceedingJoinPoint joinPoint) throws Throwable{
User user = new User();
try{
Object o = joinPoint.proceed();
user = (User)o;
}
finally{
userLogService.insertLogin(user);
}
}
}
Model: User类
@Data
@NoArgsConstructor
@AllArgsConstructor
public class UserLog implements Serializable {
private Integer id; // 唯一标识符
private String username; // 用户名
private Timestamp time; // 登录/出时间
private Boolean type; // 登录登出类型 true:login, false:logout
private static final long serialVersionUID = 1L;
}
运行结果及报错内容

我的解答思路和尝试过的方法
尝试过检查xml文件的namespace, 通过插件也可以正常转到目标代码, 也加入了@MapperScan注解, 该有的@Service之类的注解也有.
不知道如何解决问题.
我想要达到的结果
构建一个用户记录的切面.
对于所有的"登录"操作, 记录各各次登录的时间、用户，存入UserLog表格中.
可以通过测试, 结果是正常向数据库中插入一条登录的信息, 包括id, username, timestamp, type.
