MyBatis的映射器接口而不是XML文件

Question

我與MyBatis的工作，這是我的配置，它是工作：

mybatis-config.xml:

<?xml version="1.0" encoding="UTF-8" ?> 
<!DOCTYPE configuration 
PUBLIC "-//mybatis.org//DTD Config 3.0//EN" 
"http://mybatis.org/dtd/mybatis-3-config.dtd"> 

<configuration> 
    <settings> 
     <setting name="cacheEnabled" value="true" /> 
     <setting name="lazyLoadingEnabled" value="true" /> 
     <setting name="multipleResultSetsEnabled" value="true" /> 
     <setting name="useColumnLabel" value="true" /> 
     <setting name="useGeneratedKeys" value="false" /> 
     <setting name="autoMappingBehavior" value="PARTIAL" /> 
     <setting name="defaultExecutorType" value="SIMPLE" /> 
     <setting name="defaultStatementTimeout" value="25" /> 
     <setting name="safeRowBoundsEnabled" value="false" /> 
     <setting name="mapUnderscoreToCamelCase" value="false" /> 
     <setting name="localCacheScope" value="SESSION" /> 
     <setting name="jdbcTypeForNull" value="OTHER" /> 
     <setting name="lazyLoadTriggerMethods"  value="equals,clone,hashCode,toString" /> 
    </settings> 

    <typeAliases> 
     <typeAlias type="com.beitech.cagb.secure.api.model.UserDataResult" 
      alias="UserData"></typeAlias> 
    </typeAliases> 

    <mappers> 
     <mapper resource="com/payulatam/ppp4/secure/api/interfaces/user- mapper.xml" /> 
     <!-- <mapper  class="com.beitech.cagb.secure.api.interfaces.UserMapper" /> --> 
    </mappers> 

</configuration> 

user-mapper.xml:

<?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="com.beitech.cagb.secure.api.interfaces.IUserDao"> 

    <select id="getUserData" resultType="UserData"> 
     select 
     usuario_web_id as usuario_web_id, 
     tipo_usuario_web as tipo_usuario_web, 
     email as email, 
     nombres as nombres, 
     apellidos as apellidos 
     from 
     pps.usuario_web u 
     where 
     u.usuario_web_id=#{userId} 
     and u.email=#{mail} 
    </select> 

</mapper> 

IUserDao:

package com.beitech.cagb.secure.api.interfaces; 

import org.apache.ibatis.annotations.Param; 
import com.beitech.cagb.secure.api.model.UserDataResult; 

public interface IUserDao { 

    public UserDataResult getUserData(
     @Param("mail") final String mail, 
     @Param("userId") final Integer userId); 

} 

但如果我之間切換：

<mappers> 
    <!-- <mapper resource="com/payulatam/ppp4/secure/api/interfaces/user- mapper.xml" /> --> 
    <mapper class="com.beitech.cagb.secure.api.interfaces.UserMapper" /> 

使用這個類，而不是XML文件UserMapper：

package com.beitech.cagb.secure.api.interfaces; 

import org.apache.ibatis.annotations.Select; 
import com.beitech.cagb.secure.api.model.UserDataResult; 
import org.apache.ibatis.annotations.Results; 
import org.apache.ibatis.annotations.Result; 

public interface UserMapper { 

    @Select("select usuario_web_id as usuario_web_id, tipo_usuario_web as tipo_usuario_web, email as email, nombres as nombres, apellidos as apellidos from pps.usuario_web u where u.usuario_web_id=#{userId} and u.email=#{mail}") 
    @Results(value = { 
     @Result(property="usuario_web_id",javaType=Integer.class,column="usuario_web_id"), 
    @Result(property="tipo_usuario_web",javaType=String.class,column="tipo_usuario_web"), 
    @Result(property="email",javaType=String.class,column="email"), 
    @Result(property="nombres",javaType=String.class,column="nombres"), 
    @Result(property="apellidos",javaType=String.class,column="apellidos") 
}) 
UserDataResult getUserData(String mail, Integer userId); 

}

我得到這個錯誤：

org.apache.ibatis.binding.BindingException: Invalid bound statement (not found): com.beitech.cagb.secure.api.interfaces.IUserDao.getUserData

我有這個測試類：

package com.beitech.cagb.secure.api; 

import org.junit.Assert; 
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 com.beitech.cagb.secure.api.interfaces.IUserDao; 
import com.beitech.cagb.secure.api.model.UserDataResult; 

@RunWith(SpringJUnit4ClassRunner.class) 
@ContextConfiguration(locations="/META-INF/spring/pu.xml") 
public class UserDaoTest { 

    @Autowired 
    private IUserDao userDao; 

    @Test 
    public void testUserDAO(){ 

     Assert.assertNotNull(userDao); 
     UserDataResult userDataResult = userDao.getUserData("ana.sandoval@pagosonline.com", 500101); 

     Assert.assertNotNull(userDataResult); 
     System.out.println("UserData: " + userDataResult.getUsuario_web_id() + " " 
      + userDataResult.getEmail() + " " 
      + userDataResult.getTipo_usuario_web() + " " 
      + userDataResult.getNombres() + " " 
      + userDataResult.getApellidos()); 
    } 

} 

我想，也許是因爲在xml文件我在接口定義命名空間是這樣，而不是：

<mapper namespace="com.beitech.cagb.secure.api.interfaces.IUserDao">

的問題是，在測試我應該使用映射器（接口）的一個實例使其工作：

@Autowired 
private UserMapper userMapper; 

@Test 
public void testUserDAO(){ 

    Assert.assertNotNull(userMapper); 
    UserDataResult userDataResult = userMapper.getUserData("ana.sandoval@pagosonline.com", 500101); 

    Assert.assertNotNull(userDataResult); 
    System.out.println("UserData: " + userDataResult.getUsuario_web_id() + " " 
      + userDataResult.getEmail() + " " 
      + userDataResult.getTipo_usuario_web() + " " 
      + userDataResult.getNombres() + " " 
      + userDataResult.getApellidos()); 
} 

現在它的工作。
