Mapped Statements collection does not contain value for

[matrix1984]

今天搞了个MyBatis+Spring的Demo，本来好好的，不知道是因为执行了mvn install/clean等命令，突然就不行了，哎，太折腾了。

下面贴下spring和myBatis的配置：


appctx-common.xml（省略了beans的namesapce）:

        <!-- 开启Autowired、Common、Persistence及Required标注的支持 -->
	<context:annotation-config />
	
	<context:property-placeholder location="classpath:jdbc.properties" />
	<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
		<!-- Connection Info -->
		<property name="driverClassName" value="${jdbc.driverClassName}" />
		<property name="url" value="${jdbc.url}" />
		<property name="username" value="${jdbc.username}" />
		<property name="password" value="${jdbc.password}" />
		<!-- Connection Pooling Info -->
		<property name="maxActive" value="${dbcp.maxActive}" />
		<property name="maxIdle" value="${dbcp.maxIdle}" />
		<property name="defaultAutoCommit" value="false" />
		<property name="timeBetweenEvictionRunsMillis" value="3600000"/>
		<property name="minEvictableIdleTimeMillis" value="3600000"/>
	</bean>
	
	<!-- MyBatis integration with Spring as define sqlSessionFactory -->
	<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
		<property name="dataSource" ref="dataSource" />
		<property name="configLocation" value="classpath:mybatis/mybatis-configuration.xml" />
		<!--<property name="mapperLocations" value="classpath*:cn/git/mis/common/model/mapper/*.xml" />--> 
	</bean>
	<!-- 采用扫描指定包的mapper接口，而不是一一定义每个mapper -->
	<bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
		<property name="basePackage" value="cn.git.mis.common.model.mapper" />
		<!-- <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" /> -->
	</bean>
	
	<!-- transaction manager, use JtaTransactionManager for global tx --> 
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource" />
    </bean>
	<tx:annotation-driven transaction-manager="transactionManager" />

mybatis-configuration.xml:

<configuration>
	<typeAliases>
		<typeAlias alias="User" type="cn.git.mis.common.model.bean.User" />
	</typeAliases>
</configuration>

UserMapper.xml:

<mapper namespace="cn.git.mis.common.model.mapper.UserMapper">
	<insert id="insertUser" parameterType="User" useGeneratedKeys="false" keyProperty="id">
		insert into T_USER(id,gender,username,password) values(SEQ_USER_ID.nextval,#{gender},#{username},#{password})
	</insert>

	<select id="getUser" resultType="User" parameterType="map">
		select * from T_USER where username = #{username} and password = #{password}
	</select>
	<select id="getUserById" resultType="User" parameterType="java.lang.Long">
		select * from T_USER where id=#{id}
	</select>
	
	<update id="updateUser" parameterType="User">
		update T_USER set gender=#{gender}, username = #{username} where id = #{id}
	</update>
	<update id="updateUserPwd" parameterType="map">
		update T_USER set password=#{password} where id = #{id}
	</update>
	
	<delete id="deleteUserById">
		delete from T_USER where id = #{id}
	</delete>
</mapper>

各位大虾帮看下哪里有问题。

MyBatisTest.java

public class MyBatisTest {
	private static ApplicationContext xmlAppCtx = null;
	static {
		xmlAppCtx = new ClassPathXmlApplicationContext("classpath:spring/appctx-common.xml");
	}
	
	@Test
	public void userTest() {
		// Query
		Map<String, Object> param = new HashMap<String, Object>();
		param.put("username", "Langhia");
		param.put("password", "123456");
		User _user = mapper.getUser(param);
		Assert.assertNotNull(_user);
	}
	
}

最近在看mybatis 遇到了和您一样的问题，麻烦您能解答一下，这是什么原因啊？
