解决方案

解决方案二：
<mapperresource="dao/UserMapper.xml"/>这个应该写全路径<mapperresource="com/tgood/tc/cp/businessbase/dao/UserMapper.xml"/>
解决方案三：

<mapperresource="dao/UserMapper.xml"/>这个应该写全路径<mapperresource="com/tgood/tc/cp/businessbase/dao/UserMapper.xml"/>

谢谢你的回答，不过我该成你说的这样还是报同样的错误。
解决方案四：
这是用到的jar包<properties><junit.version>4.11</junit.version><commons-logging.version>1.1.1</commons-logging.version><dubbo.version>2.5.3</dubbo.version><javassist.version>3.15.0-GA</javassist.version><spring.version>3.2.6.RELEASE</spring.version><slf4j.version>1.6.6</slf4j.version><log4j.version>1.2.9</log4j.version><zookeeper.version>3.4.5</zookeeper.version><zkclient.version>0.4</zkclient.version><mybatis.version>3.2.3</mybatis.version><mybatis-spring.version>1.1.1</mybatis-spring.version></properties><dependencies><dependency><groupId>commons-logging</groupId><artifactId>commons-logging</artifactId><version>${commons-logging.version}</version></dependency><dependency><groupId>com.alibaba</groupId><artifactId>dubbo</artifactId><version>${dubbo.version}</version></dependency><dependency><groupId>org.javassist</groupId><artifactId>javassist</artifactId><version>${javassist.version}</version></dependency><dependency><groupId>org.apache.zookeeper</groupId><artifactId>zookeeper</artifactId><version>${zookeeper.version}</version><type>pom</type></dependency><dependency><groupId>com.101tec</groupId><artifactId>zkclient</artifactId><version>${zkclient.version}</version></dependency><!--spring核心包--><!--springframestart--><dependency><groupId>org.springframework</groupId><artifactId>spring-core</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-web</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-oxm</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-tx</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-jdbc</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-aop</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-context-support</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-test</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-beans</artifactId><version>${spring.version}</version></dependency><!--springframeend--><!--junit测试包--><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>${junit.version}</version><scope>test</scope></dependency><!--日志文件管理包--><!--logstart--><dependency><groupId>log4j</groupId><artifactId>log4j</artifactId><version>${log4j.version}</version></dependency><dependency><groupId>org.slf4j</groupId><artifactId>slf4j-api</artifactId><version>${slf4j.version}</version></dependency><dependency><groupId>org.slf4j</groupId><artifactId>slf4j-log4j12</artifactId><version>${slf4j.version}</version></dependency><!--logend--><dependency><groupId>com.tgood.tc.cp.icloud</groupId><artifactId>iCloud-BusinessBase-api</artifactId><version>1.0-SNAPSHOT</version></dependency><dependency><groupId>org.mybatis</groupId><artifactId>mybatis-spring</artifactId><version>${mybatis-spring.version}</version></dependency><dependency><groupId>org.mybatis</groupId><artifactId>mybatis</artifactId><version>${mybatis.version}</version></dependency><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>5.1.26</version></dependency><dependency><groupId>com.mchange</groupId><artifactId>c3p0</artifactId><version>0.9.2.1</version></dependency><dependency><groupId>org.mybatis.generator</groupId><artifactId>mybatis-generator-core</artifactId><version>1.3.2</version></dependency></dependencies>

解决方案五：
jdbc.url=jdbc:mysql://114.215.159.133:3306/chargenet?useUnicode=true&amp;characterEncoding=utf8;zeroDateTimeBehavior=convertToNull没有用过=这种写法，都是直接用=
解决方案六：

谢谢你的回答，不过把你说的去掉之后还是报同样的错误。
解决方案七：
<beanid="sqlSessionFactory"class="org.mybatis.spring.SqlSessionFactoryBean"><propertyname="configLocation"value="classpath:spring/mybatis.xml"/><propertyname="dataSource"ref="dataSource"/></bean>

检查看mybatis.xml的配置
解决方案八：
引用6楼Inhibitory的回复:

<beanid="sqlSessionFactory"class="org.mybatis.spring.SqlSessionFactoryBean"><propertyname="configLocation"value="classpath:spring/mybatis.xml"/><propertyname="dataSource"ref="dataSource"/></bean>

检查看mybatis.xml的配置

<?xmlversion="1.0"encoding="UTF-8"?><!DOCTYPEconfigurationPUBLIC"-//mybatis.org//DTDConfig3.0//EN""http://mybatis.org/dtd/mybatis-3-config.dtd"><configuration><typeAliases><typeAliasalias="user"type="com.tgood.tc.cp.businessbase.model.User"/></typeAliases><!--指定映射文件--><mappers><mapperresource="com/tgood/tc/cp/businessbase/dao/UserMapper.xml"/></mappers></configuration>

我的配置是这样
解决方案九：
<?xmlversion="1.0"encoding="UTF-8"?><!DOCTYPEconfigurationPUBLIC"-//mybatis.org//DTDConfig3.0//EN""http://mybatis.org/dtd/mybatis-3-config.dtd"><configuration><typeAliases><typeAliasalias="user"type="com.tgood.tc.cp.businessbase.model.User"/></typeAliases><!--指定映射文件--><mappers><mapperresource="dao/UserMapper.xml"/></mappers></configuration>

这样也不行
解决方案十：
我猜要么是id重名，要么就是bean重复加载。用删bean慢慢排除
解决方案十一：
引用9楼sphinx1685的回复:

我猜要么是id重名，要么就是bean重复加载。用删bean慢慢排除

我说的是mybatis中的sqlid，不是spring的beanid
解决方案十二：
UserMapper.xml我一般是如下来加载的，不用configLocation<beanid="sqlSessionFactory"class="org.mybatis.spring.SqlSessionFactoryBean"><propertyname="dataSource"ref="dataSource"/><propertyname="mapperLocations"value="classpath*:sample/config/mappers/**/*.xml"/></bean>

可以试试这种方法。
解决方案十三：
Spring与MyBatis集成的官网文档
解决方案十四：
Errorcreatingbeanwithname'sqlSessionFactory'definedinclasspathresource[spring/applicationContext.xml]:这句话是关键
解决方案十五：
还是目录结构的问题，分不清你哪个是source文件夹，哪个是普通包<mapperresource="main/resources/dao/UserMapper.xml"/><bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">        <property name="configLocation" value="classpath:main/resources/spring/mybatis.xml" />        <property name="dataSource" ref="dataSource" />    </bean>
解决方案：
试试吧，看报其他错没
解决方案：

我这个是maven结构，不存在main和resources文件夹的。按照你的写法直接爆红了。就是这么写：spring/mybatis.xml可以直接点击到
解决方案：
引用13楼j762878367的回复:

Errorcreatingbeanwithname'sqlSessionFactory'definedinclasspathresource[spring/applicationContext.xml]:这句话是关键

我也知道这是关键，关键是怎么处理。
解决方案：
引用11楼Inhibitory的回复:

UserMapper.xml我一般是如下来加载的，不用configLocation<beanid="sqlSessionFactory"class="org.mybatis.spring.SqlSessionFactoryBean"><propertyname="dataSource"ref="dataSource"/><propertyname="mapperLocations"value="classpath*:sample/config/mappers/**/*.xml"/></bean>

可以试试这种方法。

这样写也报同样的错误。
解决方案：
dubbo和你的spring包冲突吧，dubbo本身自带spring的参考下这个帖子试试：http://blog.csdn.net/xiazou/article/details/20545555
