Cadence ADE实战：1GHz VCO相位噪声仿真全流程（附PSS/Pnoise避坑指南）本文详细介绍了在Cadence ADE环境中对1GHz VCO进行相位噪声仿真的完整流程。重点剖析了PSS（周期性稳态分析）和Pnoise（周期性噪声分析）两大核心引擎的关键参数设置与避坑指南，帮助射频与模拟IC设计者准确评估VCO性能，解决仿真不收敛、结果异常等常见问题。阅读详情

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>
